you upgraded because you thought it wasnt a proper router? as long as it works in the places you need it should be ok right? as long as you are connected its ok. its possible sky give out crap wireless routers though, just like you suspected with orange. but like i say, if ur connected it shouldnt be a problem.
did you also get the free McAfee sub ? If you did is it working okay ? Cos mine's an absolute b'stard.
I'm getting shut It doesn't always load up when we turn on and so SKy won't connect. Pain in't arris.
