If the wireless adapter, wireless router and all other devices in your network are wireless-N, the following settings should be configured on your router for optimum wireless-N performance:

Wireless network name (SSID)

The latest wireless-N routers broadcast unique wireless network name (SSID). When your computer scans for available wireless networks, your router’s SSID should be listed in your computer’s wireless configuration utility.

For security purposes, it is recommended that you personalize the default SSID to your own unique SSID

Wireless Channel

The default channel setting for most routers is either Auto or Channel 6-2.437 GHz.

QUICK TIP: To avoid interference, Channel Width should be set to 20MHz if there are a lot of 2.4GHz wireless networks in your area. The recommended channels are 1, 6, and 11 since they are considered non-overlapping channels. For Wireless-N routers, it is best to leave the channel as Auto, if you are not experiencing any connectivity issues.

IMPORTANT: Setting the channel width to 40 MHz on 2.4 GHz network will allow you to use 2/3 of the entire Wi-Fi band, thus having a higher chance of interference. It is advisable to use 40 MHz if you live in areas with less crowded wireless networks. If you're unsure, you may leave the channel width at Auto. This will automatically adjust the settings to 20 or 40 MHz, depending on which best fits your network.

Wireless Security or Passphrase

It is the encryption method used to protect a wireless network from intruders. For best wireless-N performance, encrypt your router with WPA2-AES
