Finally got it sorted I think the fact I threatened the hg612 with a hammer was the decisive moment in all this. Got it working in partnership with my Rt-n66u the wireless range is greatly improved and so far I haven't experienced any loss of sky fibre service or WiFi but I have a couple of further questions if there's anyone can help and I apologise if I'm in the forum to ask but it is related. 1 The SR102 was giving me 15-16MB/s but I'm only getting 9-10MB/s with the hg612 and rt-n66 is it possible to increase the settings to make an improvement.
2 Does anyone know if and how I can connect to sky's on demand service with the rt-n66 on the sky service network menu I've got a connection to broadband router but the connection to On Demand has fail.
