My configuration is Mullvad (Wireguard) installed on the router.
IVPN app (Wireguard) installed on the PC.
I installed the official Wireguard client on Android and used Mullvad.
I have had no problems with this configuration for over two years.
But things have changed in the past few days.
Neither IVPN on the PC nor Mullvad on Android can connect at all, or even if they do connect, the speed is so slow that it is unusable.
I tried installing the official Mullvad app on both the PC and Android, but even though it is Mullvad, it does not connect at all, or even if it does connect, it is still unusable.
I tried changing Mullvad on the PC to OpenVPN, and all servers could be connected, but the speed remains terrible.
I decided to install IVPN on the router. Then I was able to connect to Mullvad on the PC and Android without any problems, and the speed was the same as before.
I also tried installing ProtonVPN (Wireguard) on the router, and it connected smoothly as well.
I contacted Mullvad support and was disappointed with the surprisingly nonsensical answers.
"Try using TCP443 with OpenVPN" "Are you connected via Wifi?"
(It took me over 24 hours to get this answer...horrible support)
My conclusion is that there must have been some big change in the way Mullvad connects in the last few days, but I can't find any information about it anywhere.
Does anyone know what changes Mullvad made?
