Followed the directions in the manual. Essentually:
Manually assign the DIR-826L an IP
Plug one of the LAN ports on the DIR-826L into a LAN port on my router connected to the internet
When I do this, the Wi-Fi clients connected to the DIR-826L are given an IP from the master router, however the clients get a dLink generated 404 error at Accesst_Point_IP/error-404asp
I can open the DIR-826's configuration pages from a wi-fi connected client or a wired PC on the main network.
What am I doing wrong?
Update: OK, I have tried everything I can think of and I can't get this working... no matter what I do, it seems to want to route the traffic to the WAN interface on the DIR-826 even though that isn't the gefault gateway. Also, when connected to the AP through Wi-Fi, I can't access other computers on the LAN, which is very odd... it seems this thing wants to route all traffic through the WAN interface, even traffic that is supposed to stay on the LAN subnet.
