Hello everyone. I was lucky and found a listing for a used AirPort Extreme A1354 model for incredibly cheap ($10). My roommate is moving out and will be taking his horribly hacked Linksys wifi router with him thankfully. (he installed some firmware crack that makes it horribly unstable and I am convinced it is the core of our connectivity issuers we occasionally have here) I plan to replace his hackbox router with the new to me Airport Extreme. This is what I need to connect to it. 1 x xbox 360 wired 1x HTPC wired (Windows 7) 1x HP Pavillion dv9000 wireless n (Windows 7) 1x MacBook Pro 1.1 wireless g (until Airport extreme card us upgraded) 1x iPad 2 1x PowerBook G3 “lombard” wired occasionally (OS X 10.4) 1x unknown Dell Laptop wireless g (windows 7) 1x hp Pavillion ze4500 wireless g (windows XP Pro,may not be capable of WPA2) 1x Generic Home built Windows PC wireless g (Windows XP Pro) 1x WD 250 GB USB HDD via USB port for Time Machine purposes. I am concerned about the mix of Wifi types as well as Operating systems in this network. Anything I should look out for with this setup. The Dell Laptop and Generic XP Pro machine will be ging away at the end of April thankfully.
