Step 1
Evaluate your needs. Do you need the superfast speeds that a draft-N network will provide, or do you just need a speedy connection to the Internet? Wireless networks using the 802.11a or 802.11g protocols can deliver up to 54 megabytes per second, more than enough to handle any cable or DSL Internet connection. Draft-N promises up to 270 megabytes per second and there are enhanced 802.11g routers that will deliver up to 240 megabytes per second.
-
Step 2
Consider compatibility. All draft-N and 802.11g routers will "drop down" to handle the slower 802.11b devices. Draft-N can also handle 802.11g. Unfortunately, the 802.11a protocol is left out in the cold.

Step 3
Consider the range you need your network to cover. The signal from most of the standard wireless networks will begin to fade outside of 150-to-200 feet indoors and possibly 300 feet outdoors. Draft-N gives you a much wider range.
-
Step 4
Check wireless security built into the routers. Most wireless routers offer WEP or other security to keep prying computers from accessing your network. Many also give you double security and firewall protection. Without this anyone driving by or within range can access your network.
-
Step 5
Make sure all devices that will be on your network can be upgraded to handle whatever standard you choose. Intel says most notebooks using their Core 2 Duo processors can easily be upgraded to handle draft-N.
