Well it's now set up and running, after some 'interesting' wrestling with the Mandarin which wouldn't allow a translation to get into the damn thing to start with! However now it is set up I have to say it is twice as quick as the Virgin SH3 on the WiFi and the range is extremely good. It has the rather amusing settings for power of off sleep, so-so and go through the wall!
It's going to take a few more days of set up because there are still several devices on the SH3 which will need to be transferred across before I can turn the hub off WiFi. Despite the range being good at the front of the house, at the rear there is no signal strength at all, what you get for thick walls perhaps.
