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.
This kinda sounds like a TCP retransmission issue. Do you have a server available somewhere? Can you run iperf3 in both ways and see the retransmission rate?
You may also want to run TCP with both CUBIC and BBR for this test since that may also isolate shallow buffers versus corrupted packets.
I had issues with the Proton VPN app on my desktop, but my laptop had no problems despite them both using Linux Mint. However, I had no problems with Proton if I set it up via OpenVPN, and Proton has a great guide on doing that.
Thank you. I also have strange anomalies with ProtonVPN and my EndeavourOS setup. I have been meaning to go the OpenVPN route as it allows port forwarding whereas the ProtonVPN app on linux doesn’t. I only recently moved over from Mullvad because reasons, and it’s been an annoying transition.
You’re welcome :)
This has worked nicely! Thanks
I’m glad it worked out for you! You’re welcome :)
Proton on Linux is annoying to say the least. I’ve got it mostly working on my distro and without a DE. Have you checked the protovnpvn_reconnector service, assuming you’re on systemd? It’s kind of odd that it just slows to a crawl but maintains connection.
