Just bought one of these off eBay to replace the Asus DSL-AC68U that was letting me down (sent it back and got a full refund).
Well I'm impressed with the netgear, really easy to setup, connected to sky fibre with no issues.
I have just switched to BT Infinity 2 and also was easy to setup with no connection issues, no connection drop outs like the Asus had, good wifi speeds and coverage. I did had an issue with IP address reservations, where by all my devices, even though they had reserved IP's were not getting the right IP address, I rolled the firmware back from v1.0.1.10 to v1.0.0.48 and this resolved the issue, this is a known issue on the Netgear forum.
I went for this particular Netgear model as it has a Lantiq dsl chip and I'm on a ECI cabinet which has the same chips in.
