I think any Newbie will suffer a bit getting a wireless network going. They are a pain, although if you are only using Windows XP life is a bit easier. I'd recommend reading a few dummies guides on the internet before you start.
The only pitfall I had was that the internet connection wouldn't work until I deleted my old internet connections. This is because a small program stored in the router dials into the internet for you, rather than Windows doing it, which is handy because you never have to dial in again.
One rather important point (I'm assuming you're in the UK I don't know why) which I rarely see mentioned is that the UK uses PPPoA, whereas almost the rest of the world uses PPPoE. You don't need to worry about this, however if you buy a different router not all of them support PPPoA so be sure to check. When you come to set up your hub remember it's A not E.
One thing I don't like about this modem is that it sometimes 'drops' my wireless connection. The cause of this I can't say, it's a job for their support and I never bothered to call yet because it doesn't happen often enough to anger me. I would also recommend you DON'T use the hardware firewall that it comes with, and instead buy yourself a good software firewall. This is simply because it's sooooooooo much easier. Zonealarm is a decent free one. I use Symantec Internet Security.
The information and instructions are excellent, if you want to check yourself beforehand go to the support section on their website and download the manual for the modem, it's a PDF file and an exact copy of what you get.
