Connection problems in GW

Hi. Recently I've had some troubles with my connection when playing GW. I load up the game fine and then play for 5-10 minutes before the lag starts. Not your typical "omg i dont have enough RAM"-lag but the lag where you can't move and then you crash to the start screen (error=007). This is really quite annoying as most of you can understand so I beg for your help! If any more info is needed, just post it and I will provide.

Thanks in advance
