They we complete crap at first, but at least now you can enable modem mode and use it just as a cable modem. Then connect your own cable router of choice.
it has arrived now, installing it was fine up until the point of going on to the internet. I didn't relies you had to ring virgin to activate it, activating took about 15 mins after speaking to a man who didn't speak very clearly. Other then that the wireless is fine at 2.4ghz and the local network setup GUI is simple. so far happy with it.
