I recently installed a Netgear wireless router on my home network. It is the the second router on my network as my AT&T internet modem is also a router. The only change I made on the second (Netgear) router is that I disabled DHCP, leaving my first router as the DHCP server. I intended to leave the Netgears' IP address as the default of 192.168.1.1, but I can't access it through a browser with that IP address. All the devices on the network are working fine connected to the Netgear router, but I can no longer make configuration changes to the router since I don't know it's IP address.
Any suggestions as to what happened and what I heed to do to access my router?
