Unfortunately I can't find my proof of purchase anywhere. Hopefully a complete reset or software update will sort it.
On a seperate note. Has anyone had any experiece setting up a Netgear AC1200 access point/wifi extender? I'm following the instructions, but I'm falling at the first hurdle. It's connected to my router via ethernet and it's switched on, but when I go to the login url (aplogin.net) it just says 'You may not be connected to your Router’s WiFi network...', even though I definitley am. I've tried to get to the login page via different devices all with the same outcome.
