We've had our broadband a couple of weeks. Everything has been fine until a few days ago, but now we are getting constant router reboots. Happens maybe once an hour, and usually takes around five minutes before it's back on again. We notice that the hub does not respond to pings during these five minutes, and Admin > Info > Uptime on the web interface shows a low value after we can reconnect, so we're assuming it is a reboot.
We've tried resetting the router to default settings, both through the interface and via the push button, but it doesn't seem to help.
