Windows freez while connected via ethernet cable to router

[kenobi]

Hello,

I have an annoying problem with my pc running Windows 7 Ultimate.
Till I connected my pc(which is a desktop without wi fi adapter) to internet using a ethernet cable and a wi fi router I had no problems. After that, randomly, but especially when browsing the internet, the computer freezes and I must restart it.

I have to mention the fact that if I connect my pc to internet using directly the cable from my ISP ( a pppoe dial-up connection) everything works fine.

All the drivers are from windows update(my Windows is genuine).

What do you suggest?
Thanks in advance.

Thank you for the reply.
I am not curently home... But, I've noticed some dump files, something kernel related, before re-formatting and re-installing, due to this persistent problem.

Should I suspect the router or is something else?

One mention:
Using TuneUp Utilities set on Turbo Mode, everything is fine.

Without seeing the dumps, I cannot comment of the causes, there is no place of a guess. This particular situation may occur due to a lot of alternative reasons.
