I'm very impessed with the Superhub 2. I had it in modem mode, simply because the Superhub 1 was and of course there was a dedicated modem before that. I got the SH2 when I got the 152Mb upgrade, and I was just lazy and put it in modem mode. After a while I took away my old dedicated router, and utilised the SH2 by itself. And I was pleasantly surprised - strong fast wireless signal throughout the house, and 100% stable. Well good enough !!! The only thing I couldn't do was set Google DNS servers in it so I'm back to using Virgin's ones. But that isn't a big deal.
