Arma 2OA kills internet connection since last past (video)

Okay, since the last patch/update, i ve been having issues with the game, and from some research i did i found out that multiple people have this issue (steam forums etc).

The problem is (watch video for more details) everytime i try to connect to an online server, the game will crash my internet connection, not only the game losing connection, but everything.

I have the game for more than 2 years, and i never had any similar issue (or with any game at all). I tried different routers,ports,firewalls,reinstalling etc. but since other people have this issue aswell its sure that its not from my side. Im not sure but i believe its something with the latest patch (gamespy shutdown... etc) and propably something is flooding the internet connection... Anyway, any help is appreciated.

Got pretty much the same issue here.

It usually happens after one hour of playing.

One of the following hapens:

1. Network conection is lost completly.
   
2. Arma and TS are working fine but anything else does not work (including other computers).
   

This happens on all computers that I have.

And it also seems that I can always ping outside servers just fine but not anything else (like loading the webpage located on that server). My ISP also did not detected any problems on the line.

Sounds like the same thing I'm experiencing with a headless client -> http://forums.bistudio.com/showthread.php?182432-Headless-Client-troubles-since-1-63-amp-Steam
