Stuck on Connection, HELPPP

Stuck on Connection, HELPPP

Hey, me and my friens leveled up some chars.

Yesterday we could play without any problem, today he tryed to log and hes stuck on " Connecting ", i can log myself, so i though he was ban so i logged to hes account, it worked perfectly.

We play on Frostwolf, we could lvl up to 70 then he crashed and when he tryed to relog it was stuck on " Connecting" in start Screen when he enter password etc, thanks.

He tryed on others private servers ( Pandawow, pandashan ) same problem, he restarted hes modem, finally he could log in both but still not warmane, do any of you know what is the problem ? He made another account and same problem, so it doesnt come from hes account but from hes pc or something, anyone have this problem or anything ? Please help.

Sorry in advance for that bad english i'm french.

Thanks so muuch for your helps and ty for reading.
