I have a HP ProBook 4540s laptop that uses a Ralink RT3290 Wireless adapter. It barely works with Ubuntu. If it does connect, the signal strength is very weak with a very slow Link speed of 6MB/sec, even while I am just 3 meters away from my router. It frequently loses connection as well.

  • Have you tried opening the additional drivers app to check if there's a proprietary driver that works with Ubuntu? – To Do May 26 '20 at 08:54
  • Yes, but there is nothing. – groenem May 27 '20 at 09:48
  • Does these help? https://askubuntu.com/q/253632/27968 and https://unix.stackexchange.com/questions/115958/how-do-i-get-a-ralink-rt3290-wireless-card-working-on-debian-jessie – To Do May 27 '20 at 12:00
  • No, none of them are working. They are all outdated. Seems like the problem is in the kernel since version 4 with no fix yet. – groenem Aug 28 '20 at 11:07
  • @groenem were you able to overcome this problem? – Elgin Cahangirov Sep 25 '20 at 11:22
  • No, not at all. – groenem Sep 28 '20 at 07:54
  • On my PC, it doesn't even turn on. – Akib Azmain Turja Jan 09 '21 at 13:27
  • check this out maybe https://forums.linuxmint.com/viewtopic.php?t=318580 , it's fairly recent (distro version came with 5.0 kernel, so possibly extensible to other 5.x kernels). Apparently it might be an issue with power management, where in order to conserver battery, the wifi card doesn't get enough power to maintain a stable connection. – Esther Apr 06 '22 at 18:13
  • another person said turning off "Wake by WLAN" in BIOS fixed the issue, maybe see if your BIOS has that option and try it – Esther Apr 06 '22 at 18:16
  • I found this solution that seems to work in 2022. https://xn--deepinenespaol-1nb.org/wiki/reparar-y-reinstalar-conexiones-wifi-ralink-y-realtek/#rt3290sta – kumiko Apr 06 '22 at 18:02
  • Hi, thanks for the more recent feedback on this issue.

    The first one did not work for me. The second one I am not sure yet, but it looks like it is keeping the connection now. The third one was not the resolution for me, as the "Wake by LAN" was already off in BIOS, but I was still losing connection.

    So the second one looks like it is working.

    Thanks

I had the same problem where the connection would last like 10 min then die. I found that the solution proposed by SinfMaster in this link worked for me https://unix.stackexchange.com/questions/115958/how-do-i-get-a-ralink-rt3290-wireless-card-working-on-debian-jessie

  • I have already tried that one, but it does not work. I still have a weak and very slow connection that drops frequently, actually more than I can use it. – groenem Oct 20 '20 at 06:51
  • I am curious as to why the solutions mentioned so far was only working for kernel 3.x.x. and not anymore for kernel 5. Surely whatever has changed to break the software driver not to work anymore, could be found and brought back from the old workable kernel? – groenem Apr 05 '21 at 03:20
