I’m experiencing really odd network behavior on Fedora Silverblue. Internet will cut in and out between extremely slow speeds downwards of 100 B/s for minutes at a time followed by normal speeds for a few minutes. For context I can get as high as 100 Mb/down. The internet never cuts out completely, just slows.
I was using Kinoite and this started happening as soon as I did a clean install of Silverblue a couple days ago. I’ve used Silverblue on this hardware in the past with no problem. It happens on both Ethernet and WiFi and I’ve already tried restarting my router. No other network device on my network has any problems and accessing stuff on the LAN is lightning fast. It’s definitely a Fedora or GNOME issue as I have a laptop running Silverblue and it upgrading from 38.20230823.0 to 38.20230828.0 has caused it to have the same issue.
Not everything has problems. For some reason Steam isn’t affected by this at all, it starts up fast and maintains fast download speeds. Running a ping test to 184.108.40.206 results in minimal latency. I’m able to be in Discord calls and stream YouTube and Spotify just fine. But when I run any command to download updates, try and connect to my VPN (it doesn’t work at all) or try general browsing with Firefox it’s terrible.
I don’t see any phantom programs taking up bandwidth running
nethogs. What I do see are applications that are trying to connect to something taking forever to even appear in the the list. This image demonstrates what I’m talking about, Discord was trying to open for 1:27 at that point and nothing showed up for it in the list (192.168.5.50 is a local network device). It seems like once a connection is established everything is fine, but initially starting that connection takes ages.
