I have an older Linksys wireless router and have a wireless adapter on my desktop that has worked flawlessly since day one. We also own two laptops with built in wireless cards. Neither of these will connect to my home network, but they do get a signal from the neighbor across the street without any problems.
I know very little about wireless networks. I'm sure the problem is that a box isn't checked, or something simple like that. Where should I start with this?
