I have a combined modem/router from Xfinity that I am trying to use as my main router, and a DIR-636L that I am trying to use as an AP. I followed this guide to set it up: http://forums.dlink.com/index.php?topic=40856.0
Everything worked fine originally, but about 30 minutes later, I am getting a message that I must "Sign In" to the wifi network through a webpage in order to access the internet. This webpage does not exist, and I cannot find a configuration setting on my router to turn this off. Connection to the internet through the LAN ports over ethernet still works.
I have both routers set to a mixed G and N signal, with the same SSID and password. The secondary router is set to channel 6 and the primary router is set to channel 1. Both networks are using WPA/WPA2 and TKIP/AES. The primary router has an ip of 192.168.0.1 with dhcp from 192.168.0.3-192.168.0.252. The secondary has an ip on 192.168.0.200. Both have a subnet mask of 255.255.255.0. The ethernet from the primary router is plugged into a LAN port of the would-be AP. The firewall of the AP is completely disabled. I turned off DNS relay on the AP. The internet connection type is DHCP on the AP, although I don't think this should matter as there is nothing plugged into WAN. Note: This is the internet connection type for the router, not the network settings. I have DHCP turned off in the network settings.
Any suggestions of things I should try to fix this issue?
Thanks for the help.
Edit: This is the "webpage" it is trying to get me to sign in at, that doesn't exist: mini_httpd/1.19 19dec2003
I tried changing the SSID to something different than the primary router and am still getting the same issue.
