Just updated to Windows 10 Creators update and my WiFi speed is now very slow when accessing files over network share. Prior to the upgrade I would get 10Mbs data transfer speeds as shown in file copy window. Now I am lucky to get 50Kbs! I have an Intel Dual Band AC-7265 WiFi adapter running the latest Intel WiFi drivers. If I switch to Ethernet then I am back to 30Mbs. I tried un-installing the WiFi adapter & then re-adding but no change. I have no custom TCP settings either.
The WiFi properties show it has connected at 300 Mbs.
The weird thing is that I can write files over the network at >10Mbs, it is only Reading that is very slow.
I tried on another PC also running Windows 10 Creators update and performance there is as expected (>1Mbs).
Is there any diagnostic tool anywhere that will let me find out what is going wrong?

Type troubleshooting in the left lower corner search to open the troubleshooting control panel.
Run the network adapter and internet connection troubleshooters.
If these fix you have completed troubleshooting.
If the above don't fix the wireless then perform the next steps.
Click windows and x keys simultaneously and click on device manager.
Expand network adapters.
Right click on the wireless AC, then view properties, then driver.
View you computer manufactures web site for up to date drivers for your computer.
Uninstall and reinstall drivers for wireless.

Hi,
as I mentioned above, I have already done the adapter delete/re-install with latest driver.
From performing other tests this is what I seem to have:
- Very slow READ (file copy) via 1 WiFi connection point. This did not happen prior to update.
- SEND via this WiFi is fast
- READ via other WiFi connection points to the same endpoint as (1) performs as expected
- Another computer running same Win10, using same WiFi connection point & reading from the same Endpoint works as expected. So this discounts (a) a problem with the WiFi router, (b) the endpoint I am reading from
Rather puzzling. As an experiment I looked into what I could change on the NAS endpoint & found that Jumbo Frames were turned on. So I turned it off, rebooted the NAS. Now I get a file copy READ speed of 1.5Mbs - a lot better, but only 1/2 the speed of the WRITE speed (I would expect READ to be higher). Now, Jumbo Frames don't apply to WiFi, only to 1Gbit Ethernet adapters, so this is even more puzzling!
So I have better performance now, but not as good as it was.

see if one of these is useful:
https://support.microsoft.com/en-us/help/4000432/windows-10-fix-wi-fi-problems
http://www.drivethelife.com/windows-10/fix-no-wifi-available-after-windows-10-update.html
For the wifi you can check your speed with ping command from admin command prompt. For example ping google.com Then you can also run round trip commands RT. These mostly find problems related to your internet provider.
https://www.howtogeek.com/208030/how-to-set-up-a-nas-network-attached-storage-drive/
One of my old internet providers had software updates and software pushes that required a proper sequence for rebooting. If that was not done in the right sequence there was a noticeable difference in internet speed. If you have no noticeable difference with Ethernet cable comparisons then that narrows down the problem.

Hi Cartacus2,
I am experiencing a similar behavior after creators update,
also tried driver uninstallation, update, bios update, netsh winsock reset, uninstall vpn client, many different things
my NIC is Intel AC 8260,
the behavior is for example:
- skype for busines is not loading completely,
- outlook does not complete send/receive,
- opening of specific websites is slow (for example also speedtest.net)
- remote desktop connections are difficult to establish and slow in displaying
the odd thing is it happens at our corporate site,
at home wifi is fast.... weird....
I discovered that if I establish a VPN connection I can work smoothly even in our corporate wifi.....
do you have to possibility to test a vpn connection through your wifi?
I will let you know if I discover something new.

Having the same issue on Intel AC 8260.
Very, very slow WIFI. Updated drivers to latest version. This has happened since the creators update.

2) "Update driver" and choose "Browse my computer for driver software"
3) "Let me pick from a list of available drivers on my computer" and choose "Intel(R) Dual Band Wireless-AC 7265 Version: 17.15.0.5 [22.2.2015]" then Next and that's it.

Hi Ladifor and MarverX,
which version did you have before downgrading to 17.15.0.5?
Do someone has an idea how to fix this for Ac 8260?
it gives me problems on creators update with:
19.50.1.5
19.20.3.4
19.1.0.4
not sure which other versions are available for 8260 for my hardware.....

I'm actually having the opposite problem. I have the same NIC (Intel 8260) and my internet speeds are great >100 Mbps after a reboot. As soon as I connect to my work VPN, my speeds drop to <1 Mbps until I reboot again. Even disconnecting from the VPN doesn't help. No internet traffic is being routed through VPN.

I just rolled back to the Anniversary Update. Everything is fine again. I'll just have to wait until this is solved before upgrading.

i'll echo the same fix worked for me. Going back to the control panel and rechoosing the network adapter seems to have fixed the problem.
Can you please elaborate? I have tried everything in this thread and I can not for the life of me get my wifi(Intel AC 7260) to work as it used to before this dreaded update. I have FTTH and 200/100 mbps connection.
I tried rolling back to drivers 17.15.0.5, latest intel drivers. I uninstalled the creators update and it's still the same. I reset my laptop COMPLETELLY, ie clean install and I still get barely 70 mbps on download. FUnny thing is my upload goes even over 100 mbps. I am at my wits end here...how can it still be broken after a clean install? My chinese smartphone maxes out my 200/100 connection easily...
Any advice appreciated.
Saturday, April 22, 2017 8:05 PM
Go to the wifi properties (several ways to get there).
From there i picked "configure" on my Realtek -
Go to Advanced... Pick wireless mode. I turned off automatic. and picked IEEE 802.11b/g/n and said ok.
Connectivity seems much more stable.
Tuesday, April 25, 2017 9:28 PM
Hi LadiFor,
so there are three factors and also three possible solutions for the problem:
- driver (solution is downgrade version)
- creators update (solution is uninstall creators)
- some wifi setting (since the problem seems only to happen in some locations)
going back to 17.15.0.5 seems to be the downgrade version solution for AC-7265,
unfortunately there is still no downgrade version solution for AC 8260 since it is newer,
the detective work is interesting, but it would be much more interesting to know which wifi setting is causing this problem, what works strangely with creators update and drivers higher than 17.15.0.5, so we could keep latest drivers and latest update,
but I tried many setting regarding wifi (band, power) or regarding netsh parameters, like autotuning or rsss, still no luck,
do someone has other ideas?
greetings
Samuel

Yesterday i've installed (Clean Install - no update!) Creators Update on my HP 15 ba044 Laptop with all released updates.
Well - i've tested three different wifi adapters (internal and two different USB adapters) - and the wifi was very, very slow (max 1 mbps).
To verify this behaviour i've done a complete new clean install of the older Windows 10 version (v1607) and the speed was ok with all adapters (!) like before.
Has anyone an idea? An addional information: Each wifi adapter has a Realtek chipset (8188CU, 8188EU, 8233). Windows 10 installs the driver itself. Changing the driver doen't change a thing.
Maybe it's a very big bug in Creators Update.
Thanks a lot!

Hi,
Decreasing your MTU for WiFi interface to 1400 may solve the issue. I have fixed my issue by this method.
0. In the administrator's command prompt,
1. Check the name of your WiFi interface.
> netsh interface ipv4 show subinterfaces
2. decrease the size of MTU of the wifi interface. Please replace "Wireless Network Connection" with your WiFi interface name.
> netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1400 store=persistent
BTW, May I ask your WiFi environment?
I have a pc with the same NIC, AC8260 and have the slow trouble with my office environment(Cisco Aironet 802.11ac AP), but don't have the trouble with wifi in my home(Linksys 802.11ac AP). I fixed the issue of office environment by this method.
The slow phenomenon is only by TCP downloading, not caused when I try TCP uploading and UDP downloading/uploading. I believe that there are TCP related bugs in Creators Update.
I guess it's not a best solution, it's only workaround. The issue should be fixed by the update of device driver or windows.
Wednesday, April 26, 2017 3:10 PM
Hi notnext,
I were sure I did try setting a lower MTU, cool, now it looks good if I set a lower MTU
in fact it seems another solution,
in fact maybe the best for 8260,
our wifi is Cisco, so maybe it's a problem with PMTUD.....
Thanks,
I will let you know if I know more.

Hi,
I got the similar problem on my 8260 when I upgraded to the Creator Update. I supposed my campus routers were also Cisco while I have no ideas about the exact model. I tried to set a lower MTU to 1400 but there seemed no sign of improvement. Will the Window 10 fix this problem in the next updates? Or it will be perfect if you got any ideas to solve it right now. I will keep following the thread, please let me know when you got the solution.
Thanks

We troubleshooted the problem with our network expert,
we did also some packet sniffing on client side with Microsoft Message Analyzer, and saw differences,
it seems windows with creators update, intel and our wlan infrastructure is not acknowledging some packets, analyzer shows some potential errors,
the solution was to reconfigure our cisco wlan from MSS 1363 to MSS 1360,
so adjusting the "tcp-mss-adjust" value,
actually working quite good on my lenovo X1 yoga, AC 8260 with default MTU (1500) on client side, latest driver with creators update.

Thursday, April 27, 2017 4:18 PM
I also can report success with lower MTU setting on an Intel 8260 card. Changing driver versions did not work for me (maybe the 17.15 driver does not exist for the 8260? I could not find it anywhere)
One thing to clarify, to get the list of interfaces, I ran
netsh interface ipv4 show subinterface
Then, like the directions above say, run (You need to start the Command Shell as Adminsitrator to make this change) :
netsh interface ipv4 set subinterface "Wi-Fi" mtu=1400 store=persistent
where "Wi-Fi" is the name of the interface the first command gave you.
Lastly, you can verify the MTU is set correctly by executing the first command again.
Thanks for the solution, this was driving me crazy!
Friday, April 28, 2017 7:53 AM
We also reconfigured "tss-mss-adjust" value of our Cisco WLC and the issue was solved. It's far better than client-side workaround. Thanks!

I had exactly the same issue. After one of the lastest windows updates, my WIFI connection did not get any faster than 18Kbs! A lot of connection failure issues (not connected to internet messages)
I was able to fix it by un-installing the latest update (related to network VM ware updates) and by re-installing my Dell Dual Band Wireless driver (from hard disk, as updating driver from internet did not work). Now it is working again, hope it will not return with the next update.
Saturday, April 29, 2017 7:37 AM
I have a Broadcom BCM4360 based Wi-Fi card. So far none of the TCP/IP tweaks work. I tried updating the driver and that had no effect. There are very few driver releases for this card. Only connecting out via VPN makes the issue go away.

Disable-NetAdapterRsc -Name Wi-Fi worked in my environment.
Intel AC-8260 with driver v19.50.1.5.

Another *solution* to this problem (yep, I'm here with a client that has the same - only not on WiFi but on NiC (update: actually, it's on his laptop, just confirming now if it's WiFi or NIC connected)...
Start, start typing 'network reset' - and open Network Reset. And (of course), perform it.
That works for my client.
Then Windows Update (presumably) comes along a few days later and kills it again.
I need to identify the driver and stop it from updating.
I don't really know how.
(I made a wee Sway site for my client...)
https://sway.com/rmxrRGxe7LD9d5ct
Be keen to hear how I might achieve what I need to do - ie. stop Windows Update from stuffing up his PC again.
I'm also a bit worried that the Speccy report might not contain the info I need. Is there another wee util I could get him to run that will provide driver info perhaps?
Cheers, Duncan.
Update:
The info given in this thread, looks good and promising - will see if I can get back on my client's PC and try some of this stuff...
Cheers, Duncan.

Thank you, for the record, the Disable-NetAdapterRsc -Name Wi-Fi (Powershell command) also worked for me (intel 8265 with latest driver v19.60.0).
Wednesday, June 21, 2017 6:11 AM
The powershell Disable-NetAdapterRsc -Name Wi-fi solution worked perfectly ON a high-end ZBook Studio G4 with an Intel Dual Band Wireless-AC 8265.
I had first noticed the problem when using Remote Desktop to connect to a remote host. Persistent lag / high latency delayed the screen redraw response by a up to a few seconds and even sometimes left redraw artifacts. It was not usable. In Remote Desktop's full screen mode, the toolbar's connection quality indicator would typically show only two bars ("good") even though much older and lower-powered equipment in the same location consistently managed four bars (excellent). Switching from a 5.0Ghz WLAN to a 2.4Ghz WLAN did not work. Even switching to a completely different WLAN router accomplished nothing. However, the above symptoms would disappear when physically plugging the laptop directly into an Ethernet LAN port on the same WLAN router. At the same time, no network issue was apparent when performing basic network diagnostic tests or online speed/latency tests.
Thank you for the solution!

My goodness!
3GB of update for 1703. Total nonsense I didn't ask for or have the slightest interest in.
WTF is provisioning kiosk devices anyway?
Can't use my computer for 90mins while the thing installs.
When it comes back internet via WiFi is at 1997 dial up speed.
After another hour on the phone using the same WiFi I am glad to have read this - thank you it worked!
But.... How is Microsoft still in business???? Consumer updates trashing internet connection? 3.5GB updates? WHY!!!!
Total garbage through and through.

I also experienced this issue after upgrading to Windows 10 Creator's edition.
My Download/Upload speed over WiFi dropped from 100Mbps down/50Mbps up (equal to my broadband fibre connection), to 5Mbps down/50Mbps up.
I first fixed the problem by disabling my Bluetooth Adapter (in Device Manager) - which is not ideal.
My Wireless driver for "Intel(R) Dual Band Wireless-AC 7265" was the latest version 19.51.0.4 (March 2017).
After seeing the above solution from MarverX, I followed the instructions (to downgrade to version 17.15.0.5) by following the steps:
1) open Device manager - Right click "Intel(R) Dual Band Wireless-AC 7265"
2) "Update driver" and choose "Browse my computer for driver software"
3) "Let me pick from a list of available drivers on my computer" and choose "Intel(R) Dual Band Wireless-AC 7265 Version: 17.15.0.5 [22.2.2015]" then Next and that's it.
After that, I enabled my Bluetooth again.
My WiFi speed now works as expected!
So although disabling Bluetooth did work, downgrading the WiFi driver is the better solution for those that need Bluetooth.

I have a Broadcom BCM43142. I got my Creators Update late on Windows 10 Pro, just a few weeks ago. Immediately I began noticing that my desktop computer's WIFI reception had suffered poorly. Right now, I'm sitting here with only one bar. Before it was at least 3 or 4 (full) consistently. NOTHING else has changed with my network.
I confirmed my suspicions yesterday by doing a speed test. My connection speed was only 2 Mbps! TWO! All of my other devices, including my 7 year old laptop running Windows 10 Home (with Creators update) as well as my Android phone are connected at 28 Mbps.
I tweaked with my WIFI Adapter settings in Device Manager a bit and was able to make some changes that got my speed up to around 17 Mbps, but this is still appalling. Before, I was connected at 28 Mbps just the same on my desktop. Even after my WIFI Adapter settings changes, my WIFI signal is still pitiful through this desktop.
It seems as if the update has not affected my 7 year old laptop, just my 2 year old desktop running 10 Pro.
And by the way, the Broadcom drivers are the latest - from November 2016.
Very disappointed! Everything was great before and I was one of the few folks who never complained about Windows 10. I think it's a great operating system. If I could run an Ethernet cable up here, I would, but unfortunately I'm forced to connect wirelessly, although my router isn't far away at all with a clear line of sight.

Hi everyone,
I was having the same problem after installing the Creator's Update, but I'm using a Asus AC-56 Wifi stick. None of the solutions proposed here seemed to work (though I must admit I tested them rather quickly, so I didn't reboot the system after each attempt).
However, I found a solution for my scenario after reading through some more discussion on that issue. There is a new Realtek driver (April 2017) that works perfectly fine for me.
As there might be more people with similar hardware, I thought I'll post the link to said driver here:

I also fixed my performance (and intermittent disconnects) by reducing MTU size
netsh interface ipv4 set subinterface "Wi-Fi" mtu=1400 store=persistent
Could not find anything in my tp-link router's configuration related to MTUs.
I bought a brand new HP Pavilion Laptop 15-CC504LA, that has a Realtek Wifi adapter. Driver name reads Realtek RTL8723BE 802.11 bgn Wi-Fi Adapter
PS: Looking forward to buy the internal Wireless card that supports AC Wifi.

Worked for me too! Thanks - i had pretty much resigned this to be broken hardware.

Thanks this worked for me too, my 5 year old motherboard doesn't seem to like newer drivers

Hi folks,
The easy way to fix this is through Yamisoft's Windows 10 manager. It's free 30 days ( and u only need an hour max)
Go to network - wi fi manager and find your network. Make sure that the laste collum is marked "Allowed".
Go to front side repair Center - system repair 1. Press SystemComponents after uncheck hidden and MC system files. Let it run and restart. Problem fixed - voila. Worked for me. Intel N-7260 must be updated to ver. 18.33.8.2. of 06-08-2017)
Really hope it works for u 2.
Cheers Charlie

i've been struggling off and on with this issue now for about a week or so w/1709 and Intel 3165 wifi and even my newly bought intel 8265. after looking through my event logs, i noticed that the moment i connected to my wifi's 5Ghz network (802.11ac, 5Ghz, wpa2, hidden); the error log would fill with errors about hardware resetting.
once i switched back to my 2.4Ghz version of my network; internet and lan working fine.
i then tried to use a static ip since i'd seen others mention that in this thread but still same issues. finally it dawned on me about the channel bandwidth and possibly the 40mhz band causing it. So went into my wifi network adapters settings and switched from auto to 20mhz only for channel settings. Reset my network adapter and bam... connected to 5Ghz and getting much better speeds (only 13MB/s but way better than not even being able to connect)
i may try to update drivers again and see if that fixes it but had played this game prior to finally finding this fix for my situation. again all my other devices i have in my home such as my yogabook w/win10 pro and iphone and ps4 all work fine as they are.
also here is the event log error i kept seeing before i changed channels:
The description for Event ID 7002 from source Netwtw04 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
\Device\NDMP21

Thank you! Worked for my Realtek.
1st went to computer vendor ASUS site for driver; reinstalled from there; did NOT work!
The updated driver from Realtek site worked:

I have found the solution which worked for me and the solution is that "Latest is not always the best"
I installed the backdated version of the drivers of my Broadcom 802.11ac Network Adapter which initially had parameters
Driver version:7.35.118.73
Date: July 17
to
Driver version:1.558.53.0
Date:10 April 16
I rolled back my Broadcom drivers through Drive Talent software and my speed has again increased now from 1 Mbps speed to 30 Mbps speed which is the maximum speed promised by my Internet Provider.

This helped for me:
1) open Device manager - Right click "Intel(R) Dual Band Wireless-AC 7265"
2) "Update driver" and choose "Browse my computer for driver software"
3) "Let me pick from a list of available drivers on my computer" and choose "Intel(R) Dual Band Wireless-AC 7265 Version: 17.15.0.5 [22.2.2015]" then Next and that's it.
Thanks! This worked for me as well, I downgraded to version 17.0.0.34

I also experienced this issue after upgrading to Windows 10 Creator's edition.
My Download/Upload speed over WiFi dropped from 100Mbps down/50Mbps up (equal to my broadband fibre connection), to 5Mbps down/50Mbps up.
I first fixed the problem by disabling my Bluetooth Adapter (in Device Manager) - which is not ideal.
My Wireless driver for "Intel(R) Dual Band Wireless-AC 7265" was the latest version 19.51.0.4 (March 2017).
After seeing the above solution from MarverX, I followed the instructions (to downgrade to version 17.15.0.5) by following the steps:
1) open Device manager - Right click "Intel(R) Dual Band Wireless-AC 7265"
2) "Update driver" and choose "Browse my computer for driver software"
3) "Let me pick from a list of available drivers on my computer" and choose "Intel(R) Dual Band Wireless-AC 7265 Version: 17.15.0.5 [22.2.2015]" then Next and that's it.After that, I enabled my Bluetooth again.
My WiFi speed now works as expected!
So although disabling Bluetooth did work, downgrading the WiFi driver is the better solution for those that need Bluetooth.
Oh my god disabling buetooth adapter worked for me "Intel(R) Dual Band Wireless-AC 3168", i don't use buetooth so i don't care. I was breaking my head for days, thank you so much.

i never could get the intel dual band wireless-ac 8260 chipset to work reliably in several new (VERY expensive) Panasonic CF-54 laptops. my experience has lead me to believe the problem is the massive Proset bloatware, not the barebones drivers or the chipset. This is my fix for W7, but the steps are the same for W8/10:
I spent days (weeks really) trying everything I could think of and many suggestions from intel and the internet as well. nothing worked. the chipset was balky in connecting if it would connect at all, and when it did connect, it was almost always REALLY, REALLY, REALLY slow and frequently disconnected! And this was the case with multiple different routers, both old and new.
In complete despair, I finally decided to completely nuke the MASSIVE (and as far as I could tell, nearly useless) bloatware known as Intel Proset/Wireless and instead just install the basic Intel WiFi drivers and let Microsoft manage the WiFi (which Microsoft has almost always done flawlessly since Vista SP1) and see if that might fix the problem. It did fix the problem!
Here's what to do:
- Download the barebones Intel drivers specific to your OS version for the 8260 wifi chipset from here:
https://downloadcenter.intel.com/download/27206
For my Windows 7 x64 system, I downloaded WiFi_20.0.2_Driver64_Win7.zip:
Unzip the downloaded driver file into its own folder, but don't do anything else with it yet.
Go to Programs and Features in Control Panel and Uninstall the installed Intel Proset/Wirless software. Remove everything, including "settings".
Next, manually delete the two intel wifi driver files from Windows/system32/drivers, namely netwfw02.sys and netwfw02.dat OR netwfw04.sys and netwfw04.dat (or perhaps both or even some other number besides 02 or 04). This is an important step, because uninstalling intel driver software lately does not always actually delete the old driver files, and I've had replacement intel driver installs silently fail because they were unable to delete and/or replace existing driver files, leaving a total mess.
(The worse case i've encountered is that after uninstalling the intel HD Graphics 520 display drivers, over 200 driver files are left behind that HAVE to be manually deleted AFTER uninstalling, because if they are not manually deleted, the new driver bundle will absolutely NOT install correctly leaving things like graphics acceleration completely broken.)
- Now go back to the unzipped barebones wifi drivers folder and execute DPInst64.exe (DPInst32.exe for 32-bit systems) followed by executing iprodifx.exe.
And that should be it. Windows should popup a balloon from the taskbar telling you that a new wifi device has been installed and you should be good to go. Not only should the intel wifi now function flawlessly, but you've also eliminated a massive amount of unnecessary bloatware, including several background processes that run at all times, consuming both CPU and memory.
btw, if auto update reinstalls Proset, any problems are likely to come back ...
also, note that i've posted this information multiple times on intel boards and they keep deleting my posts - intel absolutely refuses to acknowledge that their Proset bloatware for the 8260 is utter garbage and is wrecking havoc with users stuck with the 8260.

"With Windows*10, the OS has it [= the Intel® PROSet/Wireless Wi-Fi Connection Utility] embedded":
https://communities.intel.com/thread/84754
Is Intel® PROSet/8260 truly the problem? And if so, can anything be done about it (by a computer layman) on W10?
I have tried about ten different fixes, including most of the above, for my daughter's desktop wifi, which averages 200 kbps. Nothing works.

I know it has been a while since this was posted, but I figured I'd comment just in case anyone was looking for an answer and came upon this post. The ping command is NOT a good method for testing your internet speed (bandwidth). While in a lot of cases, ping (latency) and bandwidth (speed) seem to share similar statistics, e.g. high ping equals low bandwidth, they are in fact, not directly related. It is possible to have a low ping while experiencing low bandwidth and vice versa. For anyone looking to test their internet speeds, I highly recommend using the site www.speedtest.net. It will give you the ping, download speed, and upload speed of your device.

Hi, on my ac 8260 i did at devise settings MIMO power safve mode change to Static SMPS and everything start to work fine.

It is fine to use speedtest.net, but I find pinging the router gateway to be a reliable indication of the stability of the WiFi connection.
I am battling this issue on several HP ProBook 470 G5 laptops with Realtek WiFi chipset. I've tried all the suggestions so far, and no fix. It is worse on some access points than others. The D-Link DAP-2553 really puts this issue to the test. I tried changing settings in the D-Link AP, and none improved the issue. I tested a Startech USB WiFi adapter in the laptop which has a different WiFi chipset, and it works better, but still not 100%. Microsoft did something in this update to break drivers, and generally make WiFi performance unstable. I hope they are working on this issue and issue a fix soon, because it will turn a lot of people off to Windows. The whole world is dependent on WiFi now.

Do you know the way Wi-Fi works? It is based on contention in order to avoid collision and retranmission. If your site has too many neighbor WLANs maybe the spectrum is full and the connection do not perform fine due to the way the 802.11 standard works.
Additionally, Wi-Fi speed is not what it's advertised by vendors, as it depends on the chipset capabilities, the driver maturity, the O.S. maturity as well, the RF medium (occupancy and interference), the AP configuration and the backend performance (LAN, WAN, remote sites).
The wireless LAN chipset vendors (Intel, Broadcomm, Realtek, ...) use to update the drivers frequently to fix security and performance issue so keep the driver up-to-date.
Monday, August 27, 2018 7:11 PM
It is a good suggestion, but too many neighboring WLANS is not my problem. I tested with no WLANs within 300 feet, and still "no go".
I'm thinking the Realtek chips are not fixable.

Hi
I'm having the same problems but my driver is an intel 8265 ver 20.60.0.7. My version of windows is 1709 and I can't rollback because that's the version my laptop came with. I've tried to update the driver and that makes the problems worse. I've also changed the MTU and that didn't work. I hope someone can help.
Friday, May 3, 2019 4:54 PM
I have the Intel 8265. What do I do if I follow your steps and it comes up with 3 model items the first 2 listed as Intel(R) Dual Band Wireless-AC 8265 (Intel) and the third says Intel(R) Dual Band Wireless-AC 8265 (Microsoft). Which do I choose?
Thanks for any help.
