I am trying to help my firend go wireless and she lives in an apparment bulding. If I get a Linksys WRT54G and a wireless card would the signal be strong enough to go through two thick walls. It is not a large apartment nor is it small it is about the size of the average 1st floor in a house. I am placing the router in her living room which is to the front of the apartment and the ther wireless card is going in her laptop which will be in her room at the back of th apartment. I know that this wireless technology has a range of 300ft but would be the same in this case? If you could just let me know and Ill get them going.
