When me and my bro play games sometimes like Generals, we sometimes do Direct Connect so it is just the two of us. Well anyways, for some reason, the connection stopped. It used to be where my old PC sometimes couldn't connect to his newer one, and sometimes it would work, sometimes it wouldn't. Then one day, when we tried doing Direct Connect it was the other way around (plus it would not connect whatsoever)! Now his PC was having connection problems wheres mine had none whatsoever. It always says on his PC when he'd connect the cable "Limited or No Connectivity". What should I do?
EDIT: Why hath no one answered?
Ugh, if no one can give actual technical support on this forum, I'll get help elsewhere...
