The wireless issue was bad enough.. Need to reboot a couple of time and search a few with connection failure before getting online but not getting any connection in Nokia upgrade software irritates the friggin crap out of me. I am able to connect with it when I have it powered on so the usb cable is ok..
I start the upgrade software and do what it tell me to.. fully charged battery, connect usb, hold in the swap key (button on the front looking like a house) and then power on. I get the usb symbol on the N800 and the upgrade software search and search not finding anything.. and finally it tell me to retry again..

I have no idea on how to get this thing work again.
