Question for the fellow techies...
 

Ok, so I've had the wireless network for the apartment up and running. It's in secure mode, got network keys for everyone and all. We had to move the router out of the living room today, so I just put it in my room since I'm the resident computer geek. Roomie on the other side of the house is able to connect, but it shows up as "little-to-no connectivity." It's probably 30 feet to her computer from the router. I personally don't think it's a distance thing, because we pick up signal from other networks across the courtyard (people apparently label their networks by apartment number). Not to mention that even when it was in the living room and probably only 2/3 as far as it is now (long story), she had troubel connecting to our network. So wth could it be, other than maybe a defective card on her end?

Discuss, please.

When you're dealing with wireless signals, it could be a multitude of things. However, try to narrow it down. Is it only her laptop that has trouble connecting? What happens when you use another wireless card or another computer from the same location?

I have a wireless router setup at home that's about 30 feet from the dinning room table where I sit at my laptop. But because the kitchen is between me and the router I get a weakened signal. Lots of things can play into interference, especially wireless phones running at 2.4GHz. Test by moving your roomies pc closer to the router, or the router closer to the computer. That will rule out faulty equipment.

Try testing with another computer from the same location.

You say she's always had trouble. It could be a problem with the card.

Try changing the wireless channel on your router. This changes the frequency... if other electronic equipment (such as cordless phones) is interfering with the signal, this may help.

If all else fails, tell your roomie to associate with your neighbor's access point instead... j/k :p
