The behavior you described, frequent “Disconnected” or “Limited connectivity” messages, RSSI values showing 255, and WLAN AutoConfig failures, suggests that the issue is not limited to a single adapter model but may be related to driver stability or access point compatibility. The Realtek RTL8852BE Wi-Fi 6 adapters are known to have intermittent issues with certain firmware and driver builds, and similar symptoms can appear on Intel adapters if the AP firmware is outdated.
Since you’ve already tried upgrading and downgrading drivers, I recommend verifying that your wireless access points are running the latest firmware and that WPA3 or advanced security features are not causing compatibility problems. Disabling “802.11ax” (Wi-Fi 6) mode temporarily and forcing devices to connect via 802.11ac can sometimes stabilize connections. Additionally, ensure that power management settings for the Wi-Fi adapter are set to “Maximum Performance” to prevent the adapter from being put into a low-power state.
If the issue persists across multiple vendors’ adapters, it may point to an infrastructure-level problem. In that case, reviewing AP logs for authentication failures and testing with a different SSID or frequency band (2.4 GHz vs. 5 GHz) can help isolate the root cause.
I hope these steps provide a clearer path forward. If you find this answer helpful, please consider hitting “Accept Answer” so others can benefit from it as well.
