Change Your Wireless Network Name (SSID)

The SSID (Service Set Identification) is the wireless network name assigned to your SBG6700-AC wireless

primary and guest networks. The default SSID which is listed on the gateway label is automatically

populated in the network configuration screens. A list of SSIDs of available wireless networks in close

proximity of your home (for example, neighbors or local businesses) will display when you or someone

else in your home attempt to establish a wireless network connection. For security purposes and quick

recognition of your wireless network, it is recommended that you change the default SSID. You should

also consider changing the default wireless password or passphrase (see

Prevent Unauthorized Access

for more information).

Note

: When you change the SSID, any wireless devices that are already connected to your wireless network

will be disconnected from the network. The wireless devices will have to be reconnected to the wireless

network using the new SSID.

Do the following to change your wireless network name or SSID:

1.

Open a web browser and log onto the SBG6700-AC to open the SBG6700-AC Web Manager. See

Start the Gateway Web Manager

for more information.

Change the Wireless Channel

Network interference may occur at any time when using a wireless network connection. This may be

caused by other wireless access points that are using the same wireless channel as your SBG6700-AC

and are also operating within close proximity in your home. When experiencing wireless network

interference, changing the wireless channel on the SBG6700-AC can improve network connectivity (or

signal strength) and avoid network interference. By default, the SBG6700-AC is set on Channel 1.

Do the following to change the wireless channel on the SBG6700-AC:

1.

Open a web browser and log onto the SBG6700-AC to open the SBG6700-AC Web Manager. See

Start the Gateway Web Manager

for more information.

Note

: For 2.4 GHz Wi-Fi networks, it is recommended to use Channel 6 or 11, if it is not listed as the

Current Channel. In the Wi-Fi spectrum, there are multiple channels that overlap and thus degrade

wireless network performance. Channels 1, 6, and 11 are used for better network performance and

stability because they do not overlap.
