text: i have a dell laptop l120 and can not connect wireless at home? but i can connect at school wireless.i bought a wireless router so i could connect at home and followed the wizard but it will not connect but has a signal on the laptop and it reconizes the signal from the router but will not connect displays a error mssg. it is hard to say. . . my first guess is that maybe the wireless card does not accept the type of wave that your router is producing (like my card accepts a, b, and g connections)???
