Sky fibre router lasted 4 whole hours before giving up!

Hi, just had fibre installed today, all good to begin with, getting speedtest results of 32M on the 40 connection.
After around four hours of use, both ethernet and wifi, all the wifi devices lost internet connections. Checked the router and the wifi light is off.
OK, unplugged it, gave it a minute plugged it back in, waited for the startup and login to complete, same. All wired devices get online ok, no wifi light on.

I also am unable to access the 192.168.0.1 status page, just get this message

No data received
Unable to load the web page because the server sent no data.
Here are some suggestions:
Reload this web page later.
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

Thats on a chrome browser, IE and Safari just stay blank.
Anyone had similar or any ideas how to get it fixed. I'm thinking new router from Sky is the only way this will be cured.

Cheers
Richard
