Steam server connectivity

[XEdgarxl]

After I came back from a convention I started to get this problem when trying to connect to a ingame server.This been happening alot lately and when it does I have to disconnect the cables and replug em back in. Also I am not the only one who have this problem i heard. If you have fixed this problem before plz help me it gets really annoying.
