<td>HT (High Throughput) mode specifies WiFi channel bandwidth. 40 MHz bandwidth provides better performance but it overlaps with 4 adjacent channels on each side. Therefore, it might overlap with many other Access Points operating at adjacent frequencies. If that is the case, the router will switch back to 20 MHz mode automatically to reduce interference.<br>40 MHz is only available when the WiFi Channel is selected manually in the General Setup section.</td>
