Cannot do step 2 - new Airport will not connect to old TC
I really would like to keep my old back ups if feasible . However, each time I try to connect the new Airport TC to the old one, the connection fails . In addition, I lose the internet connection in my house . This despite the fact I leave the cable modem connection intact to the old TC. I have and LAN to LAN connection of the TCs. When I remove the new TC, the internet connection auto restores.
Any ideas out there ? Is the new TC some how trying to take over the internet connection? The new TC was straight out of the box and not reset in any way.
