The Sagem router SKY now have is crap … it doesn’t seem to be able to handle the router AND wifi functions at the same time. Mine would regularly crash and drop broadband and wifi.
I’ve now disabled the wifi on the sky router, and plugged in the old BT homehub into it with an ethernet cable. The BT now acts as the wifi access point for devices in the house and the sky router acts as the broadband connection to the wall.
Its been an extremely reliable setup. I think in the last 6 months I’ve only had to reset the homehub and router once.
I’m just about finished networking up the house, so am going to move the homehub up into the loft at one end of the house and add a second at the other end of the house. that will give me a much larger wifi area including access in the garden, and will still be 100 times more reliable that the shitty sky router on its own.
