I have a home network through AT&T U-Verse (using a 2Wire modem). I want to create a WAP such that the DHCP on the 2Wire is the DHCP for the network, and the 826L provides WAP through the dual bands (at N speeds). I need to do this for several reasons, I don't want G network speeds with the 2Wire, and I need to be on the same domain and subnet for the devices.
So I followed the instructions on Page 11 of the manual - disable UPnP, disable DHCP, change the LAN address to one on the U-Verse network (192.168.1.x), and connect one of the LAN ports on the 826L to a LAN port on the 2Wire.
What happens is, after rebooting following config changes, the devices will connect to the DLINK SSID, but will not obtain an IP address. When I connect a computer with a static IP address and log into the DLINK admin page, then do the ping tool, it cannot ping the 2Wire gateway.
I have used Reset on the bottom of the DLINK several times, gone through reconfig, and sometimes it works for a few minutes, but eventually DHCP clients stop getting addresses assigned.
Any advice? What am I missing?
