I use Sky Bb and it drops the connection after a while. I have this occuring all the time after about 15 mins. I disconnect the power to the Netgear router and after about 20 seconds connect the power and enable the lan connection.
I & even the bloke on the Sky help desk thought the router was at fault but I don't think so.
This is I am afraid seems to be a feature of the Sky BB because it is happening even after I replaced the Netgear router with a new one sent over from Sky.
