Belkin F5D8231-4 user manual Using the Bandwidth Switch, 20MHz only, 40MHz only, 20MHz/40MHz Auto

Using the Web-Based Advanced User Interface

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.
