Hello. I went to get a new router because I finally decided to get wireless. I got a Linksys WRT120N which supposedly has a decent range, according to the sellsman. On my apartment the router is about ten meters and has a couple walls between it and the computer. The computer receives really weak signal, so I called the store and they said that it's because I live in a 16th floor. If that's true I don't understand why would the height affect the range, and didn't got any results searching on the net. I would appreciate any explanation of the height affecting the signal. Thanks.
