Can't login into a game. Stuck at connecting screem.

Hello.

I have a problem. Maybe you could help me? I can't login into a game. Yesterday I logged into a game, play few minutes and got dc. So I logged in again and same story. After few minutes dc. I knew that server was updated so I decided to leave wow and do my other thing. But today I cant even login.
I'm sure that my login and password are good, I checked my realmlist and it's good, I've flushed my dns, reset my router and computer and still nothing is working. Now I will download new wow I try again. Maybe you have other solutions?
