Wifi connection dropping on university campus
Closed, InvalidPublic

Description

While using Solus, my wifi connection will randomly drop internet access, though NetworkManager shows me having a good connection to the network. A disconnect and reconnect is enough to temporarily fix the issue until next boot, though I turn my laptop on and off often enough to make it an annoyance.

A possible factor in this is that my university has a network of routers scattered across campus to provide students internet access from anywhere. The routers all use the same SSID to make switching between routers seamless, but perhaps Solus is having issues with that? I have Arch Linux installed on this laptop as well but it is having its own internet issues right now (working on fixing it now), though last I recall it was not having this same issue.

Do you have tlp installed and running?

I have tlp installed as part of the default installation and the systemd process is indeed running.

I thought it might be a power savings issue, but

  1. I have the "Turn off WiFi to save power" option disabled under power settings
  2. I have only had issues on this one network (at least, I don't recall having issues while home for Christmas)
  3. The issue only seems to happen once per boot, a few minutes after booting the computer
  4. My other computer, also running Solus doesn't have this issue

EDIT: To clarify, this other computer is a desktop that also has TLP installed, enabled, and running

For all I know, it could still be a power savings issue, though.

Try removing tlp if it is still there. We actually purged it from Solus because it causes so many issues.

tlp has already been removed. I just updated the system in case it would fix anything, but no. The connection still hung after a few minutes. I am usually connected to a VPN and I thought that perhaps it was the issue, but it still happened when I removed the "autoconnect to VPN" option.

I have the same symptoms on my home network. It's a wifi AC connection given by the ISP router-modem, and the connection drops even if in network manager it is shown as active and connected. The only solutions is to disconnect and reconnect, but the connection drops again in a few hours. This happens on battery and wired.

I honestly don't know what else can be done for this. We are updating linux-firmware and wpa_supplicant as needed. Anything else is an upstream bug in the kernel, afaict.
