10 sec after joining a server and I get connection problem.

[Guldfisk]

I recently changed internet suppliers and since then I've gotten connection problem as soon as I've joined a server, but only sometimes. Today I tried 6 different servers before I gave up and closed tf2. Why is this happening because I've allowed it in the router, in the firewall and in the router firewall. If you're had the same problem please tell me what fixed it for you.

A better internet connection fixed it for me.
