I am running Xubuntu 20.04 and have a problem with wifi reconnects: Sometimes my HP notebook loses connection to the wifi router (3 meters distance, without obstacles) and then cannot reconnect. This is the corresponding excerpt from syslog:

My mobile phone connects without problems, but my Linux notebook doesn't. After a reboot, everything is fine again, but a simple sudo service network-manager restart doesn't do the trick. Any clues?

Some wifi details:

$ sudo lshw -C network
  *-network

  • Edit your question and show me iwlist wlp58s0 freq, and tell me what channel your router is set to on the homewifi_5G-2 network. Start comments to me with @heynnema or I'll miss them.

  • Thanks for your response @heynnema ! Checked the ASUS dashboard and it shows homewifi_5G-2: Channel 100/80 MHz

  • That's strange, as the iwlist shows that you're connected to channel 52. Do you have more than one wireless network, either 2.4 or 5GHz? Does your ASUS router go to channel 140... or any of the other higher channel numbers showing in the iwlist command (high channels are better)?

  • Yes @heynnema ! I have 5 networks in total: One 2.4GHz on Channel 11 and one 2.4GHz guest network. Additionally, I have two 5GHz networks, one on 52/80 MHz and one on 100/80 MHz. Finally, one 5GHz guest network. Is there any more information I can provide? :)

  • You didn't say what channels the guest networks were set to. What happens when you connect to the "other" 5GHz network on channel 100? What brand router, just curious.

BIOS

HP 830 G6

You have BIOS version R70 01.04.05.

There's a newer BIOS available that appears to address a network problem, vesrion R70 01.05.03 Rev.A, dated 05/11/2020, and can be downloaded here.

Note: Verify that I have the correct web page for your model #.

Note: Have good backups before updating the BIOS.

  • So far it works. I will let you know, if I experience the same behavior after some time. Thanks again :)
