Using the Bandwidth Switch
This switch allows you to set the Router's wireless bandwidth modes. There are
several modes available:
1) 20MHz only
Setting the Router to this mode allows only 20MHz operation. This mode is
compatible with N, draft 802.11n-, 802.11g-, and 802.11b-compliant devices, but
will limit N, draft 802.11n-compliant devices' bandwidth by half. Reducing
bandwidth to 20MHz-only operation might solve some wireless problems.
2) 20MHz/40MHz Auto
Setting the Router to this mode allows it to switch automatically between 20MHz
and 40MHz operation. This mode enables 40MHz operation, to maximize speed
for N, draft 802.11n-compliant devices when conditions permit. When a legacy
802.11g access point is presented and occupies an adjacent secondary channel,
the 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
