My college roommates and I have a house in Philadelphia that is very big and very old. I set up a wireless network so that we didn't have wires going all over the place (and so the internet service provider didn't charge us a fortune). The router is set-up on the second floor of the house towards the back. My roommate on the third floor towards the front gets no signal. So I bought a repeater, the Linksys WRE54G. I spent hours trying to set it up but since it is not compatible with the WPA2 security on the router, I haven't been able to set it up. I tried searching Google for help and read almost every article, tried everything, and still had no luck.
I don't have more time to waste on this thing, so I am looking for any other ways to expand my wireless network. I had a few questions.
Is setting up an access point similar to setting up the range expander? i.e., would it do the same job? Also, does it require running a wire or can it be done wirelessly so that I could put it closer to my roommates room?
Or, should I replace the router I currently have, which is wireless G, to a wireless N router? I'm curious about the differences between these two, i.e., does wireless N have greater range?
