Get disconnected everytime

Well i finally got AoM working for GR but now everytime i join a game either in the chatroom or ingame my internet connection closes. Not only for AoM but everything. Is gameranger causing this?
Any help appreciated

I think you can make an easy test:

Check your connection stability with and without GR... for example by calling someone on skype or going on a Teamspeak server (you'll see when you are disconnected).

And No, I don't think gameranger can make it crash. But the only way to be sure is to test it.
Sometimes, connection crashes because of router bug or ISP desynchronization.

I tried it and it seems that it wasnt GR. Anyway the problem went away in a day or so, guess it was just my connection
