WiFi 5 stoped working

Glen Liu 1 Reputation point

After I upgraded from Windows 10 to Windows11 insider programe in August, I lost the Wifi 5 connection.
I called AT&T fiber tech support and they created a new network name for me to connect using Wifi 4 (802.11n).
AT&T told me that Windows 11 has an issue with it.
Could you please check?

    From what you explained, I believe this is a bug and I advise you to open start and search for feedback and open the Feedback Hub app and report this issue.
    You may try update Windows and the Network driver.
    In worse case, roll back to Windows 10.
