Cisco Systems EA3500 manual How to control access to your network, Wireless-N Only 802.11n only

Linksys EA-Series

d.Network mode—Your choice depends upon the clients that will connect to your network. If all of your devices are Wireless-N capable, you can select Wireless-N Only for either or both bands.

On the 5 GHz band, you can select:

•• Mixed (default), which accepts connections from 802.11a or 802.11n clients

•• Wireless-N Only (802.11n only)

•• Wireless-A Only (802.11a only) On the 2.4 GHz band, you can select:

•• Mixed

•• Wireless-B/G Only

•• Wireless-N Only

•• Wireless-G Only

•• Wireless-B only

e.Security mode—You can set up different security options for the 5 GHz and 2.4 GHz networks. If the security mode you select requires a passphrase, a Passphrase field appears, and you must enter a passphrase. You can select:

•• None (no security)

•• WEP

•• WPA Personal

•• WPA Enterprise

•• WPA2 Personal

•• WPA2 Enterprise

•• WPA2/WPA Mixed Personal

•• WPA2/WPA Mixed Enterprise

Tip

Wireless-N networks should use the WP2-Personalsecurity mode for best performance.

f.Channel width—We recommend that you keep the default (Auto) setting for each band. In Auto mode, the router and the network clients automatically switch to the 40 MHz mode if:

•• Your wireless clients support the 40 MHz mode (sometimes called Bonded mode) in which two 20 MHz channels are bonded together for better performance.

Setting Up: Advanced

•• There is no adjacent interference.

With more available channels and less chance of interference on the 5 GHz band, you have the option to force the 40 MHz mode.

On the 2.4 GHz band, you can select:

•• Auto (20 MHz or 40 Mhz)

•• 20 MHz Only

On the 5 GHz band, you can select:

•• Auto (20 MHz or 40 Mhz)

•• 20 MHz Only

•• 40 MHz Only

g. Channel—Choose the operating channel for each band. Your router will automatically select the channel with the least amount of interference if you leave the default Auto setting. We recommend keeping the default settings for both bands.

h.SSID broadcast—When wireless clients look for wireless networks to connect to, they detect the SSID (wireless network name) broadcast by the router. In other words, anyone within range of your network can see your network name. To broadcast your router’s SSID, keep the default setting (Enabled). If you do not want to broadcast the router’s SSID, deselect the SSID broadcast checkbox. We recommend keeping the default setting (Enabled) for both bands.

How to control access to your network

Why would I need to control access to my wireless network? If you used the Setup CD to install your router, your wireless network is already secure. By default, Setup enables industry-standardWPA (Wi-Fi Protected Access) security using WPA2/WPA mixed mode. If you set up your wireless network manually and have not enabled wireless security, your wireless network will be an “open” network that almost anyone nearby with a Wi-Fi-enabled device could access.

What is MAC filtering? If you choose not to use the built-in security features of your router, you can still control access to your wireless network using MAC filtering. Every network device has a unique, 12-digit MAC (Media Access Control) address. Using MAC filtering, you can allow only known MAC addresses (known devices) onto your network. You can also exclude specific MAC addresses or deny them access to your wireless network.
