I just bought an Airport Extreme and everything was going great until I tried connecting my Xbox 360 to the network. When it would supposedly connect to the network but then not show any IP settings or anything else I Googled it to see if there was a known issue. The results I got said that it worked without security or, alternatively, if I followed these instructions: In Airport Utility, Option-Click (or alt click on windows keybaords) the radio setting button to get the hidden choices, and select b/g compatible, NOT n (b/g compatible), just straight b/g. That will limit each device to 54 mpbs, which is fine. Next, Option-Click your encryption setting button and select WPA Personal. Go into the InternetHCP settings (I think) and reserve an IP address for your 360 based on its MAC settings to make sure it gets the same IP all the time. In the NAT options, select that IP as the Default Host so as to cause no issues with XBox Live functionality. Restart the Apple Extreme. After its up and running, start your XBox 360, go to the last blade of the Dashboard and select your network settings - it should let you select your new WPA-encrypted network and youre good to go. I did all of that but it still didn't work. I turned off the security and it still didn't work. Are they compatible at all? Almost all of the Google results were old so I'd really appreciate it if somebody could give me the up to date accurate info. Thanks for reading.
