I can see every other Wi-Fi around me but mines. Even when I try to connect to the hidden Wi-Fi, it still don't work. All my other devices can find my Wi-Fi but this laptop for some reason can't.

    Hello Ma'Quarious Lynn Cathey Cathey,

    Since the laptop can detect other Wi-Fi networks but not the new Xfinity network, this is likely a compatibility issue between the older Wi-Fi adapter and the router’s current band or security settings.

    Could you please provide:

    1. The Wi-Fi adapter name shown under Device Manager > Network adapters.
    2. The model of the Xfinity gateway.
    3. Whether the gateway provides a separate 2.4 GHz network.
    4. Whether its security mode is set to WPA3 only or WPA2/WPA3 transition.

    Older adapters may not detect a newer router configuration even though other devices can. If possible, temporarily enable a separate 2.4 GHz network and use WPA2 or WPA2/WPA3 transition mode rather than WPA3 only.

    Please note that Windows 8 is no longer supported, so a compatible updated driver may not be available. If the adapter cannot support the router’s settings, a USB Wi-Fi adapter that supports current standards may be the practical workaround.

    An older Windows 8 laptop often misses a new router when the router is broadcasting on a band the laptop does not support, especially 5 GHz.

    Try these steps in order:

    1. Check the router band.
      • If the router has both 2.4 GHz and 5 GHz, try connecting the laptop to the 2.4 GHz network.
      • Older laptops may detect 2.4 GHz but not 5 GHz.
    2. Try the other Wi-Fi band.
      • If both bands appear as separate networks, connect to the other one.
      • This is specifically recommended when a PC cannot connect or detect the expected network.
    3. Update or reinstall the Wi-Fi adapter driver.
      • Open Device Manager.
      • Expand Network adapters.
      • Right-click the Wi-Fi adapter and select Update driver.
      • If that does not help, uninstall the Wi-Fi driver and restart the laptop so Windows reinstalls it.
    4. Check whether the network is saved incorrectly and reconnect.
      • Go to Settings > Network & Internet > Wi-Fi > Manage known networks.
      • If the network appears there, select it, choose Forget, then reconnect manually.
    5. If the network is hidden, connect manually.
      • In Wi-Fi settings, choose Hidden network.
      • Enter the Wi-Fi name and password exactly.
    6. Make sure Wi-Fi hardware is enabled.
      • Some laptops have a physical Wi-Fi switch. Make sure it is turned on.
    7. Move closer to the router.
      • This helps rule out weak signal issues during detection.
    8. If needed, use another connection temporarily.
      • Try Ethernet if the laptop has a port, or use another trusted Wi-Fi network to confirm the laptop can still connect wirelessly.

    If the laptop still sees every nearby network except the new router after trying 2.4 GHz and reinstalling the Wi-Fi driver, the most likely cause is compatibility between the older wireless adapter and the router settings.
