Hi,
I was trying to setup this modem-router for a friend on ADSL and well I can't.
If I try use quick setup then it gets to step 4 (choose names for wifi network) at which point when you press next the router will reboot and you have to start the setup all over.
If I just cancel the setup and go into the router I can change the settings but it doesn't save any changes, I can setup the ADSL settings however and I get functioning internet but with open Wifi which isn't ideal.
The router uses ajax (or similar) for its interface which I'm guessing is the issue. When I press apply, javascript runs to check my input but then nothing happens (no page refresh eg.), tried Chrome/IE on Windows and Firefox on Linux.

Been factory reset a couple of times and firmware updated but still can't secure the Wifi, anyone had similar behavior or suggestions?
