I am running into a weird issue with my WIFI/internet setup. I have a router and a NETGEAR extender that I am connecting with through a thick wall.
Unfortunately, about once every 2h, I can't use the internet anymore. I am on NixOS and network manager shows that I am still connected to the extender WIFI (that is the Gnome network manager applet shows an active WIFI connection), but opening a website doesn't work anymore, I can't ping anything not even the router, and open Google meets stop instantly.
I can fix this with a nmcli connection down XXX && nmcli connection up
command which takes 8-9 seconds.
Now the very weird thing is that recently I had a zoom call open in the zoom desktop application and it continued to work although the rest of the computer didn't have internet access anymore.
I have a few questions regarding this:
- How is it possible to be connected to the WIFI, according to network-manager, but not able to ping the default Gateway? What does a deconnect && reconnect do so that the state differs? I have already deactivated DHCP and moved to a fixed IP because I thought that might have an influence.
- Is there a faster way to refresh a connection instead of a full nmcli connection down && nmcli connection up?
- How can a zoom call stay active when I can't even ping the default gateway anymore?
Thanks for your thoughts, ideas and help
ifconfig wlo1 down
andup
but it can be worst 3) Look here for ports and fixed IPs used by zoom (in case DNS was down it can continue started sessions, or maybe start new ones) and again if GW is not pingable yes.
