However, the last few days one of my laptops has been having connection issues. If I'm in the basement (the router is on the first floor), the laptop can't find any networks, not even the ones from the neighbors. The other laptop however finds a signal and gets a good connection. When I move literally directly up the stairs in the same spot, I find a signal, though it is weak. As i get closer to the router, signal strength increases.
No viruses/trojans or anything I can find..I'm thinking it's a problem with the network card, but I'm not sure how I'd replace this in a laptop (never even worked with the hardware of a laptop, only desktops =\).
Do you guys think that's the problem, and how would I replace the card?
