Equipment: -1x Airport Extreme Base Station, Firmware 5.7, Model A1034 - the old flying saucer shaped one -1x Cable Modem. DHCP IP allocation. -1x Powerbook I just swapped out my old cable modem that was unhappy for a new one today. If I plug it into my computer, I get this IP address: xx.xxx.212.198 and everything works great. If I plug it into my Airport, I get this IP address: xx.xxx.212.134, and nothing works at all. I called my ISP and they're saying that whatever router I'm plugging it into is holding onto an old IP address, and I need to reset it and get it to let that old one go. Fast forward 10x software resets, uploading firmwares, reset to factory defaults, a hard reset with a paperclip, and I'm still stuck with that stupid .134 IP address. What gives?
