7. For Fastest Wireless-to-Wired Connections, Go Gigabit

7. For Fastest Wireless-to-Wired Connections, Go Gigabit

As of now, Wireless N can provide more than 100Mbps wireless connections, surpassing the 10/100Mbps speed of most of the Ethernet ports on networking gear today. This also applies to Wireless N routers and APs.

These ports can thus become a bottleneck in the network; slowing the data rates down below 100Mbps.

This is the case, for example, when transferring files or communicating between a wireless and wired computer connected to the same Wi-Fi router, or two wireless computers connected to two different APs on the same network.

Therefore, for best performance and to plan for the future, make sure that all your gear supports gigabit Ethernet.
