Hi on my laptop I cant use multiplayer on any of my steam games, which kind of ruins the point of them (especially TF2). Does any one have any idea what might have gone wrong.
What do you mean?
You cant play online?
Does the internet work on it in general, is Steam added to the firewall? Have you tried repairing the games via steam.
Yes I have tried repairing the games, yes the internet does work in general and yes I can't play online. I have tried spintires, gmod, tf2 and planetside 2 and none of them are able to play multi player, planetside crashes when attempting to connect to a game, gmod gets to two bars on the progress monitor and then says something like 'after 4 attempts connection timed out' which is the same message from tf2 and spintires.
Apparently my isp has been having problems so could it just be that (though my friends on the same isp could connect to servers)
Yep that seems fine too. Really odd issue. Do you have any games on another platform like Origin, Uplay or Battle.net that you could try. To help us narrow down whether it is a Steam issue.
