Help Please

[Throatseeker]

Hello I game with my RL buddy and we both play at his home. We applied for the IP exemption a while back and never really had issues playing. However here lately both of us have been randomly disconnected and kicked from the game. Including bouts of massive lag spikes and then going LD. If anyone has any insight as to what could cause this please let me know either through this thread or PM! Thanks!
