Packet loss on keep alive

I run a teamspeak 3 server (version 3.13.3) on a spare PC in my house. I have two friends connected to it (which have 0% packet loss). My wife who is on the same network as me, has 0% packet loss. But for some reason, when I connect, I have a constant fluctuating packet loss of 2-3%, with 7% on the ‘Keep Alive’ tab.

I think it’s my actual PC/Client. Because when I connect to other Teamspeak 3 servers, I get the same problem. So I don’t know what to do.
