I have a network issue on Ubuntu 20.04. Wifi randomly disconnects about every 30-45 minutes or whenever I am having a zoom call or I am watching videos in streaming. I tried to fix this by disabling the power management on the wifi card, but it didn't solve my problem. Any idea? My kernel version is 5.4.0-51-generic. Please help me, this is very annoying.

  • We don't know what is your "wifi card". – Pilot6 Oct 22 '20 at 15:37
  • There have been some issues with the -51 kernel. Run Software Updater and get the newer -52 kernel and see if that fixes the problem. – heynnema Oct 22 '20 at 16:53
  • Ok, now I have the -52 version. I'll use it for a while and I'll make you know if I have still issues – Hub One Oct 22 '20 at 19:52
  • I have also issues with the intel audio card, randomly booting recognizing only the mic (when I reboot after this issue it often works), but this seems not fixed in the -52 version – Hub One Oct 22 '20 at 19:55
  • @heynnema I have still troubles, even after having upgraded the kernel to -52 I still managed to trigger the bug – Hub One Oct 22 '20 at 21:01
  • Edit your question and show me sudo lshw -C network and iwlist scan and iwlist freq and free -h and sysctl vm.swappiness. Do you have QoS enabled in your router? Are you running with a VPN? – heynnema Oct 22 '20 at 21:54
  • Edit your question and show me sudo dmidecode -s bios-version and tell me the EXACT make/model # of your computer or motherboard. – heynnema Oct 22 '20 at 21:57

I have solved this similar problem on Ubuntu 20.10, Gnome 3.38.1, by going to Settings > Power > Power Saving > Automatic Suspend > Off.

Anyone has any news on this issues, I tried those solutions as well but it's still coming up.

I run sudo dmidecode -s bios-version and it shows A10.

Then sudo lshw -C network shows :
