700m built in wireless not reliable?

Hello.

My new 700m is great. I love this laptop. I only have on problem. The built in wireless works very unreliable.

I can connect to my network easily and all is well. But surfing will suddenly stop once in a while on anything (meaning no specific sites, etc). Now one could suggest my router, but I have no such issue on my old laptop with 3com wireless card. The router is a netgear.

Are there any known issues with this? Anything I can do?

The next step is to insert my 3com pc card and do a test with that vs the built in card and see if it is in fact the hardware vs hardware. Or if its the software used.

Thanks for any knowledge you may have on this subject.
