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 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 only
Setting the Router to this mode allows only 40MHz operation. This
mode is compatible only with N1, draft 802.11n-compliant devices.
It may affect legacy 802.11b/g devices. Use only when you have a
pure N1, draft 802.11n wireless network.
3) 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 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 Router automatically reverts to 20MHz operation to maximize
compatibility. We recommend using this as the default mode.
