I seem to have a problem with internet connectivity. I use NetworkManager with Proton VPN on an Arch KDE system. The wifi and VPN stay connected, but every once in a while the upload and download rates will go down to, at most, a few hundred KiB/s. The issue can be solved temporarily by disconnecting and reconnecting the VPN, but as I’ve had a similar issue without the VPN before, I do not know whether this is a VPN issue or a NetworkManager issue.
All of my other devices are either Windows or Android for convenience. The VPN works on Windows, but I can’t isolate this issue via that route as those devices are old and have their own issues.
I have tried running my system without vpn and this specific issue hasn’t appeared from yesterday until now. It is making me feel a little uncomfortable not having it on though.
I’m going to try another suggestion, then I’ll come back to this one if it still doesn’t work.
