I am having an issue on a completely new install of Ubuntu budgie 22.04, wifi regularly and seemingly randomly disconnects or drops significantly in speed. The behaviour is weird though as it seems to happen every time I try to run a speedtest on speedtest.net, the ping section runs fine then the down speed test starts fine before dipping to a few mbps then the test fails entirely at the start of the up speed test. Also none of these issues occur on the windows install dual booted with ubuntu on this pc so its not an issue with wifi range or the router.

I have tried a few other fixes I found from on posts of a similar issue however none have worked:

Disabling wifi powersave: I have edited /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and set wifi.powersave = 2

Disabling hardware encryption: I also disabled hardware encryption with the following command: echo "options ath5k nohwcrypt=1" >> /etc/modprobe.d/99-local.conf

I have also disabled Ipv6 and forced connection to the 5ghz band of my wifi (both 2.6ghz and 5ghz has the same SSID and unfortunately this is something I cannot change).

Here is some more info about the hardware:

iwconfig:

lo        no wireless extensions.

enp2s0    no wireless extensions.

Thank you in advance for any suggestions on how to fix the issue.

  • Are you certain that your driver is ath5k? Maybe ath9k? Please check my troubleshooting steps here: https://askubuntu.com/questions/1353705/ubuntu-20-04-wifi-keeps-dropping/1353723#1353723 Welcome to Ask Ubuntu. – chili555 May 04 '22 at 23:12
  • "both 2.6ghz and 5ghz has the same SSID and unfortunately this is something I cannot change" I am confident that this is a big part of the issue. Please try binding to the MAC address of the 5 gHz band like this: https://askubuntu.com/questions/425583/ubuntu-connect-drops-worked-for-a-while-then-started-dropping-again/425617#425617 – chili555 May 04 '22 at 23:15
  • @chili555 Thank you very much for the reply, I tried your troubleshooting steps however they did not seem to help. I am not sure if it should be ath5k or ath9k is there a way to check? Also when I tried to run: sudo iwlist wlan0 scan it returned: wlan0 Interface doesn't support scanning. – awegthrjku May 04 '22 at 23:27
  • Look at the network logs with the terminal command: sudo journalctl -b 0 -u NetworkManager. Read man journalctl. – waltinator May 04 '22 at 23:47

    I doubt that your wireless interface is wlan0. Please try: sudo iwlist scan – chili555 May 05 '22 at 00:13
  • Thank you for the responses, chili555 I added the BSSID of the 5ghz channel however it did not seem to work. waltinator I had a look at the linked thread and nothing on it has helped, I will add logs from around the time it fails during the speedtest to bottom of the post as I can consistently get it to drop out. – awegthrjku May 05 '22 at 17:36
  • Update: I managed to fix the network issues by updating the kernel, following one a guide linked in this thread: https://askubuntu.com/questions/1353705/ubuntu-20-04-wifi-keeps-dropping/1353723#1353723 I was hesitant to do this but nothing else worked, however now my display driver is broken so I guess I need to fix that now. – awegthrjku May 05 '22 at 22:16
