linksys net extender help!

I know there have to be some techies out there.  I have been having some problems getting the net extender at my apartment working.  I know they're both on the same channel, same IP range or whatever, but I'm not sure about the MAC addresses between them.  If somebody could come over and hook this up for me within this week or the following, that would be awesome!  I'd rather help out one of my own, than to jump right to craigslist.  Name your alcohol driven poison, or your price, and we'll go from there.  Thanks!
