I bought this because I knew I could do more with my router eg share files, my music, pictures on the new TV and wirelessly access my stuff when not at home.
To help you understand if you think this is for you, and what level you are compared to me (I'm no expert), this is what I could already do:
1. set up a wireless network, eg connect devices such as an iPhone, additional laptops
2. access files on my own network from every laptop / Mac... just
I did the above by guessing and playing around. eg I plugged my NAS drive
Buffalo LinkStation Live 2.0Tb DLNA Certified MultiMedia Network Storage with BitTorrent (well the 1TB of this from Amazon) and selected properties and allowed access. A bit of playing around can really do wonders.
However this is what I've managed to do since:
1. Got a better understanding of how a router accesses the internet and how if then "talks" / interacts with your home devices through DHCP, assigning IP addresses.
2. Understand the whole wireless N thing - why it's better (or not) which has helped me plan how I'm going to expand my current network. It's managed to save me money so far.
3. Tweak my home network to get a better and more reliable connection, eg I've downloaded a wireless network scanner, changed my wifi channel to one that won't clash with my neighbours. From using this book I know that I'd like a dual band router to set up 5GHz so I can avoid my neighbours' wifi, nearby microwaves and digital phone interference (as they all use 2.4Ghz.
4. Set up port forwarding on my router. I bought an IP camera from Amazon and can view (and control it) from my iPhone or laptop when I'm out and about. You also need to understand DNS but this book explains.

I found myself reading about the difference between 802.g / 802.n 4 or 5 times and other basics. The tone is very much targeted at the complete beginner (or dummy) which is OK but I had a slightly higher average understanding already. There are a few rubbish gags in there and I was hoping to ge straight to the detail on how to do something but it's a little verbose at times.
I was going to give it 3 stars as the detail is OK but it goes on and on (a bit like my review) but then I remembered all I had achieved since buying it. It's slightly out of date now as some of the things it talks about being the norm in the future are quite common, and if you're in the UK the pricing will all be in USD and out of date, therefore expensive for what you can get on Amazon now.
So I'm glad I bought it and have learned a few things. However it's made me want to buy something more technical now. If all you want to do is set up your router for the first time from your internet service provider (ISP) et BT / O2 etc then you can just follow the instructions that come with the box. However if you want to know more and make the most of the technology, then give it a go. Or at least a more up to date version.
