I recently installed Ubuntu for the first time and split my drive (now a part of it is Windows and a part is Ubuntu). Normally everything is fine (Ubuntu connects to the internet regularly), but every week or so the Ubuntu split doesn't connect to the internet. When I restart the computer and switch to Windows it can connect to the WiFi just fine. In fact, it's quite random, but after one or several restarts Ubuntu is finally connecting the the WiFi.

I found several SO questions (here, and here) about Ubuntu not connecting to the internet, but they seem to be related to Ubuntu not connecting to the internet at all (and not like mine which is sporadically).

I believe my make/model of the wifi is Intel Corporation Wi-Fi 6 AX200

  • Wifi issues are generally hardware specific. What is the make/model of the wifi adapter that you use? – Nmath Jan 15 '22 at 22:57
  • Not sure if it's this so let me know. Intel Corporation Wi-Fi 6 AX200 – Penguin Jan 16 '22 at 00:36
  • Look at the logs! sudo journalctl -b 0 -u NetworkManager. Read man journalctl. See https://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos/425180 – waltinator Jan 16 '22 at 03:19

  • whose wifi router is it? can you access it? – Andra Jan 16 '22 at 20:43
  • @Andra My router – Penguin Jan 16 '22 at 22:13
  • when this situation occurs (Ubuntu cannot internet), first, I would try to open the router management page - it would be also over wifi? If the page opens, see if there is an old lease (delete it), maybe some other parameters. And from Ubuntu side I would use Wireshark to see that the request is issued and what replies received. – Andra Jan 17 '22 at 12:53
