So, recently I had my laptop repaired for a crack in the screen. When it was taken in, we had just recently gotten our modem and it gave me Internet connection just fine. When I got it back, though, I couldn't get connection anymore. I've already tried checking the switch to make sure it was on and resetting the laptop, but it still says the wireless capability is off. I'm pretty sure the modem is fine, because I can't get Internet anywhere else either. Any idea what I could do to fix this? It's a Gateway, btw.
