Does anyone else have bought a laptop XPS M170 and have problems with their network connection?

I saw a lot of people having problems with the Broadcom 570x Gigabit Integrated Controller and the same issue I have -> losing the network connection for a few seconds...

 

Does anyone have an idea what to do? I reinstalled the latest (the same it was before) driver but it only solved the problems for 45min... I still have problems with my connection every 2-3 sometimes 5-7min. This is really unacceptable.. and want to know if someone had the same problem and was able to solve it?

 

Regards.
