The computer has been slowing down and having connection issues occasionally during this past week, but rebooting has fixed those issues each time until today. I’ve been using this computer with Tumbleweed for almost 2.5 years, and this hasn’t been an issue before, and I’ve been using it on this network 5 days a week this entire year. I don’t recall making any network setting changes on the computer or router before this happened. Rebooting (many times over the course of today while trying to fix this).Connecting to my Android phone set to USB tethering, which did show up as an ethernet interface but had the same behavior as the normal ethernet interface (as described above).Looking through the dmesg logs to see if there was some error or warning (I didn’t find anything).Starting and restarting various network-related services.Deleting the network configuration files in /etc/NetworkManager/system-connections/.Unblocking the interface with rfkill (wasn’t necessary, according to rfkill list).Delete /etc/nf and restart network service / restart NetworkManager / reboot.This isn’t an exhaustive list, since I’ve been trying for 8 hours and didn’t keep track of everything. I’m happy to give any other output that anyone wants, but that’s the obvious one that comes to mind. Notably, the router lists the computer as connected. Ping: : Temporary failure in name resolution PING localhost(localhost (::1)) 56 data bytesġ0 packets transmitted, 0 received, 100% packet loss, time ping -c10 When I try to ping my router, localhost, and a website (I had to manually copy this ping -c10 192.168.1.1 When I try to use Firefox (or connect to the VPN I use for work), it just hangs, trying to connect, until it gives up. However, after a few seconds the menu shows the connection as “limited connectivity”. I can use the menu in the bottom bar to connect to my router via Wifi, and the same menu shows a successful connection if I plug in an ethernet cable. Today, though, I lost an entire day trying to fix the network interfaces, which have stopped working. I’m on OpenSUSE Tumbleweed 20201216, and I’ve been using this installation with only occasional small issues since 2018.
