Thanks for the help guys.
The high speed we've had for a couple of years no problems. The modem is a netgear that we bought, not something from cox.
Yesterday we got a roku and the asus. Before I opened any boxes I called cox to see what I needed to do, as far as needing any passwords or such from them. They said, plug it in and follow the directions, have fun.
The "manual" actually a quick start guide was easy to follow, and as soon as everything was plugged in I rebooted it all.
I followed the prompts from the wizard and as suggested changed the ssid, password, network key, wireless securiy, set wan connect to Auto IP, wan IP to 0.0.0.0
and lan IP to "Satan's IP" 192.168.1.1
When I got to the last prompt page it asked for authentication name and password to enter, and the authenticaton window refreshes a two or three times and then goes to the 401 page. somewhere along the line the initial prompt page started saying it didn't think the wired config was set up correctly. So I checked the cables several times, unplugged them, shut down, reboot, reset, etc and still the same. If I type 192etc right into the address bar I get the authentication window and it goes right to a 401 page: not authorized.
So I tried the new passwords a few times, tried the admin/admin a few times, admin/passwrod, tried my outlook passwords, my atm pin, my ssn, my license plate, a bunch of gobbly gook I typed with my forehead while I was banging my head on the desk, etc.
I can call asus monday I just missed them yesterday by 2 minutes. So if we can't figure it out I'll just give them a call.
TLDR; Bought some new stuff that's not working. Not sure if operator error or not.
