While Wireless G is not the newest and fastest method to connecting to the internet, it is still commonly seen throughout retailers.  The prices range from about $30 for a standard model, and up to $100 on other models which offer an extended range or extended speed for those who want to get more from a Wireless G network.  Since most users with high-speed internet have transfer rates of 54Mbps to 100Mbps, this is possibly the best choice for those at home or with a small office.

Wireless routers come equipped with at least four slots so that computers may connect to it with the appropriate cable (essentially the way you would connect computers to a regular router).  It’s a good substitution for those who are using your network who either cannot or do not wish to make a wireless connection to the network.

A Wireless G Network card (laptop or desktop), or a Wireless G USB Adapter is what you need to get the best performance from a Wireless G router (match the letter names: G goes with G!).  Users with an older means of connecting (such as a Wireless B, or 802.11b) are compatible with a Wireless G router as well, but will not give you as strong a signal, therefore resulting in a slower internet speed than a Wireless G.  Anything less than a Wireless G is difficult to find these days anyway, since Wireless G is pretty much a standard in modern day wireless networking.
Wireless N routers are a far newer method of connecting.  It offers a greater range than Wireless G (up to four times), and from 300Mbps of connectivity to an even greater strength of over 1Gbps (gigabyte per second).  This is a solution that is far more suitable for a business, but is also an option for home if you want optimal speed and signal strength.  It also is less likely to receive interference from external signals.  Because of these features as well as its new technology, Wireless N does cost considerably more than Wireless G.  The cost of a Wireless N router starts from around $80, and can cost up to $260 if you want more than a gigabyte per second transfer rate.

Do these features make Wireless N a better choice over Wireless G?  Not necessarily.  The speed of your current internet connection cannot go outside of what your broadband provider already offers.  For example: if you can only transfer up to 500Mbps, that is the most any router will give you, regardless of what its full capabilities are.  If you’re unsure about the transfer rate of your internet, check with your service provider.  There’s no sense paying for optimal performance if your connection does not match it!  However, if your internet provider does provide speeds from up to 1Gbps, and you want maximum connectivity, then Wireless N is the way to go.

Compatibility
A Wireless N Network card (laptop or desktop), or a Wireless G USB Adapter is what you need in order to get the best performance out of a Wireless N router (match the letter names: N goes with N!). Wireless N is fully backwards compatible with both Wireless B and Wireless G adapters (network cards and USB adapters), although signal strength and connection speeds will not be as strong as a Wireless N adapter.
