And you checked for driver updates and/or removal reinstall? It could be a few things, up to and including bad hardware, in which case you could try a USB adapter. It could also be settings but am assuming that would have been checked out along with driver, etc.
The wireless connection on my HP laptop drops randomly for about 10-20 minutes. The machine runs well, I was wondering if anybody else has this issue on their laptop and maybe a solution. The other computers in my house hold a steady connection.
