Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
So that’s it for the shopping list. Keep in mind, though, that you do not need to go out and buy all new equipment, especially if you have compatible equipment. For example, if you have a couple of wireless B NICs, you can still set up your network with a wireless G router and use the wireless B NICs.
There is also a healthy market for the “older” standards, so if you are not one of those people who always needs to have the latest and greatest tech gadgets, you can probably get some used wireless B equipment for a good price.
