so have been happily using this modem with my biliion 7800n for last few days.
this morning the internet died, the dsl light on the hg612 now just flashes then goes off, internet works fine with the sky router.
I tried the hg612 about a hour ago and it worked!!! again, but it only lasted for 3 mins, and now refuses to connect to fiber
anyone have any idears?
