We've been having a strange issue with my brother in-law's laptop. We have 2 separate wireless networks in our house, but his laptop will only "see" one of them. All other devices like phones and other laptops can connect to both networks without a problem.
There's no mac filtering set on the router, we've tried resetting the router, tried manually connecting to the network, but it wont at all... I know it's not a driver issue because it can connect to the other network just fine.
