I've just switched from BT to Virgin XL. We have 2 laptops and a wireless printer attached to the SuperHub.
Neither of the laptops can see the printer, or each other. Going to the SuperHub page I can see all 3 devices and there IP addresses. Pinging the printer or a laptop gives "destination unreachable" errors.
Connecting the devices back to the BT Hub, all the devices can ping each other and the printer works fine.
Not, the only issue we are having with the new Super(?) Hub; but the most critical at the moment.
I dunno If I've got a superhub or not, but on my virgin supplied netgear I've got a wired device on a static IP which doesn't seem to show up on the router's config pages (though IS accessible if I try to connect to it).
