Using the Bandwidth Switch
This switch allows you to set the Modem Router’s wireless bandwidth
modes. There are several modes available:
1. 20MHz
Setting the Modem Router to this mode allows only 20MHz
operation. This mode is compatible with N1, draft 802.11n-,
802.11g-, and 802.11b-compliant devices, but will limit N1, draft
802.11n-compliant devices’ bandwidth by half. Reducing bandwidth
to 20MHz-only operation might solve some wireless problems.
2. 40MHz
Setting the Modem Router to this mode allows it to switch
automatically between 20MHz and 40MHz operation. This mode
enables 40MHz operation, to maximize speed for N1, draft 802.11n-
compliant devices when conditions permit. When a legacy 802.11g
access point is presented and occupies an adjacent secondary
channel, the Modem Router automatically reverts to 20MHz
operation to maximize compatibility. We recommend using this as
the default mode.
Using the Broadcast SSID Feature
Note: This advanced feature should be employed by advanced users only.
For security, you can choose not to broadcast your network’s SSID. Doing
so will keep your network name hidden from computers that are scanning
for the presence of wireless networks. To turn off the broadcast of the
SSID, remove the check mark from the box next to “Broadcast SSID”, and
then click “Apply Changes”. The change is immediate. Each computer now
needs to be set to connect to your specific SSID; an SSID of “ANY” will no
longer be accepted. Refer to the documentation of your wireless network
adapter for information on making this change.
