Right now it works with kernel 5.8 but in 5.11 (installed this morning along other upgrades) the wifi adapter doesn't get detected at all and apparently there are no fixes until the drivers gets patched (unless i'm mistaken). Do someone know if/when bcmwl-kernel-source will get patched?

No WiFi adapter found after moving from Windows
cn flag

Just moved from Windows to Linux Ubuntu, it says I don’t have a WiFi adapter when I have a TP-Link Archer T2U Plus plugged in.

I have looked online and most have said things like connect Ethernet and Mobile Tethering when I don’t have access to both of those.

And I have already disabled Secure Boot.

Cannot connect to wifi, while all networks are available. When I tap on any of them, just nothing happens. Also in settings of networks I was connected, password doesn't shown. Problem isn't with wifi, cause smartphone and other computers are connected to them

This is my first question here, even if I've been lurking here for a long time.

I installed Ubuntu 21.04 next to windows 10 with hopes that a newer kernel would have better support for my problem. This was not the case.

  • I enabled the "Propietary drivers for devices (restricted)" sources when I installed.

Several times a day, my wireless network disconnects (for some reason), and I see this notification:

At this point I'm not really asking about why it disconnected (though I believe it is nearby interference).

My question is why it is asking for the wireless password when Ubuntu already has it. The network is set to automatically connect, so I would think it unnecessary.
