I've been having big problems with wifi on my NC since exchanging my last unit a couple of months ago because of audio buzz/noise issues. I'm running CM7 nightlies and have tried EVERYTHING suggested to get it to be more stable. It was the usual scanning - connecting - scanning loop that many people have described.
While troubleshooting the problem I downloaded wifi analyzer from the market and it was showing my home wifi network peaking at around -85dB while my laptop right beside it was showing approximately -40dB for the same network. I reverted back to stock 1.2 to see if was related to some driver gain settings in CM7 and only saw one or two networks appear in my scanning list (including my home wifi) but not the ~25 wifi networks which were showing up on my laptop.
I made it back to BestBuy yesterday and even though my unit was exchanged a couple of months ago, they exchanged it again for me. Of course I checked the packaging of the new unit to make sure it didn't have the infamous blue-dot-of-partitioning (BDOP) before walking out.
I booted the unit, upgraded to 1.2, nootered it, restored my CM7 backup and voila! My home wifi was up around the -45dB mark and I could now see all the wifi networks in the area which showed on my laptop. I connected and its been rock solid wifi since! The bonus was I was never able to pair my Plantronics bluetooth with my previous NC and this time around, it started immediately and paired right away with no issues. It even holds the connection a couple of feet away!
So after a very frustrating two months trying everything to get the wifi connection stable, it turns out it was an issue with the hardware itself, likely an antenna/solder issue. This also confirms (although I think it was already) that the BT/wifi antenna is shared.
Sorry for the long explanation but some of you who are having these wifi issues should download wifi analyzer from the market (its free!) and take a look at the signal strength graph. If its only showing a few wifi networks and access points which are close are showing in the -70dB or less range, you might have the same hardware issue I had...
