3800HGV AirPort Extreme IP address problem in BRIDGEMODE loose internet connection on iMac
I have Uverse/2-wire3800hgv working flawlessly for years. I got a new iMac and AirPort Extreme that I put into bridge mode so the 3800hgv passes out the IP addresses. I use this 2-wire for my Windows computers wireless (works great for years!) and the AirPort for my iPad and iMac wireles....works great for a day or 3 days, then whenever my iMac wakes from sleep, I get the message "another device is using the same IP address" which it is not. If I unplug the AirPort and re-start, it works again on my iMac. The airport wireless keeps working fine, it's just the 2-wire thinks the iMac has a conflicted IP address and wont let it connect to the internet.
Is there a way to assign the iMac a static IP? Or is it the AirPort that gets a "static IP"? And is there step by step instructions on here to go into the browser settings of the 2-wire unit to do that? thanks!
