I just got a cable modem which works when connected directly to the computer. When I connect the modem to my airport extreme router and then the router to the computer I get no internet connection at all. Any suggestions?
iMac, Mac OS X (10.6.8)
HI - first a few questions - is the cable modem just a modem or is it a router also? - and what version of the Airport Utility are you using to setup the Extreme? - and what color is the light on the Extreme and is it blinking?
It's just a cable modem-no router. I'm using Airport Utility v. 5.6.1. The light is steady green.
First I am going to assume that you have set up the Extreme correctly - in that case, disable and re-enable the network adapter - this will release the last address from the modem to the computer and allow the Extreme to establish new internal LAN addresses as needed for your devices. - then you should power off all devices and take out and replace the battery if your modem has one - then power up the modem and let it fully boot - then plug in the extreme and let it start up - then turn on the computer and see if you get internet - If that doesn't work, then we have to go over the whole installation from a factory default and customize it to your requirements - let me know how it goes.
