I have just installed Ubuntu 20.04 on my HP Envy laptop and Wifi connection is terrible: when it works it is very slow and sometimes it does not work at all. No issue on Windows 10.

Here is some info:

sirfabel@bellaplx01:~$ uname -a
Linux bellaplx01 5.4.0-47-generic #51-Ubuntu SMP Fri Sep 4 19:50:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

sirfabel@bellaplx01:~$ lspci | grep Ralink
07:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe
07:00.1 Bluetooth: Ralink corp. RT3290 Bluetooth

It seems only rt28xx cards are supported:

sirfabel@bellaplx01:~$ lsmod | grep rt
rt2800pci              16384  0
rt2800mmio             20480  1 rt2800pci
rt2800lib             131072  2 rt2800mmio,rt2800pci
rt2x00pci              16384  1 rt2800pci
rt2x00mmio             16384  2 rt2800mmio,rt2800pci
rt2x00lib              61440  5 rt2x00mmio,rt2x00pci,rt2800mmio,rt2800pci,rt2800lib

Apparently this is a well-known issue, according to what I saw on the web... I tried to apply some patches I found on some forums, but none of them worked...

Can please someone help me?

Thanks!

  • Have you tried the suggestions here https://askubuntu.com/questions/763772/problem-with-rt3290-wifi-driver ? – darth_epoxy Sep 12 '20 at 12:15
  • Yes, actually the patch proposed in this thread is deprecated. As it says: "The patch will work up to kernel version v4.14, it breaks on v4.15 onwards due to the change in the kernel timer implementations". – sirfabel Sep 13 '20 at 03:19
  • Can you see specific firmware rt3290.bin in your /lib/firmware directory? – darth_epoxy Sep 13 '20 at 09:25
  • Yes there is actually! How do I use that bin file? – sirfabel Sep 15 '20 at 02:54
  • That just means that it is already installed correctly. So let's try simply a different way of updating the firmware. Run these 4 commands separately sudo apt update && sudo apt upgrade -y then sudo service fwupd start then sudo fwupdmgr refresh then sudo fwupdmgr update and let us know if the Realtek device firmware is listed in the output. – darth_epoxy Sep 15 '20 at 07:34
  • Only my harddrive is listed on the output... – sirfabel Sep 16 '20 at 03:05

I had the same issue as you with that card. I never had my wifi working perfectly even after long research, but i have found a few stuff that helped.

On what you provided, it seems that you have the right driver installed.

Step 1: Wifi chanel You should try to change the chanel used by your router. If there are many wifi's available in your area there might be some interference.

Use nmcli dev wifi to see the available wifi networks and the chanel they use. Then go to your router to change it.

Step 2: Power Mangement When doing my research, I have found that power management is causing problems with the wifi. To see if it is activated use iwconfig. It should be off or on. If it is on see How can I prevent iwconfig power management from being turned on? to turn it off.
