Here is our setup in our household: 13" MBP 13" Blackbook 13" White Macbook 12" PB 15" Dell Junk Notebook 15" Toshiba Junk Notebook Windows Desktop Computer(attached via ethernet) Powermac G4(attached via ethernet) 500GB NAS(attached via ethernet) Nintendo Wii 2x Nintendo DS's Nintendo DSi Airport Extreme Dual Band Linksys WRT54G Router Everything is wireless other than the desktops. I was quite content with the router we had, a Linksys WRT54G. It never had any problems with anything, just didn't have all of the features I desired. I bought the Airport Extreme for 2 main reasons: Wireless-N, and Wireless Time Machine Backups. This thing has proved to be a pain in the ass to configure and get working properly. Nothing I'd ever expect to be put out by Apple. I excitedly came out and hooked everything up, set it up, and got my MBP up and running, tested it on the 12" PB, and all was good so I assumed it would be good for everything else. Well, my father had connection issues with the Windows laptops, but those were resolved by deleting their previous network and setting this one up fresh. No big deal. None of the DS's will connect with the security that I have on(just WPA), and it seems that this is going to be the ongoing case, google yields few positive results. Sounds like the Wii will be a problem too, but I haven't tried it. Sooooo plan B - set up the Linksys router again and use the Airport Extreme as a bridge, effectively have 2 home wireless networks, sounds good to me. Well, this works just fine, but the wireless-n is not noticeably faster at all, and the Time Machine Airdisk thing is painfully slow(nearly useless seeming). I let it sit overnight(literally 12 hours) to do my 102GB Time Machine backup, and it got 19GB done and apparently got hung up somewhere along the night, because it just sat there and never moved again. Cool. I am running it with a 2.4GHz network and a separate 5GHz network, but they don't seem any different. I'm honestly considering just selling this and going back to my Linksys router, just because this seems like a waste of my money. Was I expecting too much out of this?
