Can't connect to online games
i was playing Diablo 3 a few days ago when i randomly got disconnected, and now can't get past the launcher. around about this time my internet changed to a fibre optic cable as my parents use it for work and needed faster internet. (i'm fairly certain the disconnection as due to the change as they had to cut it off for a few minutes) anyway after internet came back browsers were working, emails working so i tried to get back onto diablo and couldnt get last the launcher. figured ok its a new game, still a few errors. tried to play WoW and WoW MoP beta. can't get past the launcher. thought ok blizzard isn't working. tried to log onto steam. comes up with a connection error message. games like runescape and flash games still work its just my downloaded online ones that suddenly don't, and i don't have a clue why. i've tried disabling fire wall, rebooting comp, re-downloading games and checked for viruses, and nothings changed. has anyone else had this problem before/how do i fix it?!?
