OK, I've gone through the luser's manuel, surfed the net, checked the manufacturer's website, and I'm stumped.
I can connect to my ISP with my NIC connected to my Ambit 67078EU cable modem. Web, news, mail.
Hook up the WHR-G54S wireless router, Ambit cable modem to WAN port, computer NIC to one of the WHR-G54S ports. I can log into the Buffalo's internal webpage of 192.168.11.1, change settings, enable wireless security (yes, it does WPA TKIP and AES), BUT... it cannot find my ISP.
Under WAN on the home page, it says "Not determined because DHCP or PPPoE server not detected". Now WTF? My computer is set to use DHCP and not act as a DHCP server. My internet provider, Charter Communications, clearly tells people to use DHCP. The setup has worked for years.
The WAN port LED flashes with traffic almost constantly, while the port that connects to the computer NIC only flashes when I am accessing the router's internal page. I can't ping past the router. Easy Setup cannot resolve the WAN settings.
OK, I am off to a flying stop. Help?
