capability of the VAP functioning as an AP. In this mode, traffic is not forwarded to the
Ethernet port from the radio interface. In Repeater mode the Multimedia Router
transmits a beacon.
Note: WDS settings may only be configured for WLAN1, See “Wi-Fi Protected Setup
(WPS)” on page 5-33. WLAN2 only operates as an access point service.
Note: Configuring WLAN1 to operate in WDS “Bridge” mode automatically disables
WLAN2.

• HT Operation Mode – Packets from 802.11n clients are referred to as High Throughput
(HT) Greenfield packets, in other words packets that can be transmitted at rates of up
to 300 Mbps assuming that HT Channel Bandwidth is set to 20/40Mhz, see HT Channel
Bandwidth next page.
Note: Some 802.11n wireless clients may be capable of transmission rates of up to
600 Mbps, however the Multimedia Router will only be able to connect to them at
a maximum transmission rate of 150 Mbps.
• 802.11b/g packets are referred to as non-HT packets, being transmitted at lower
throughput rates. HT mixed format frames contain a preamble compatible with the
non-HT receivers. HT Greenfield frames do not contain a non-HT compatible part.
Support for HT Greenfield format is optional. An HT station that does not support the
reception of an HT Greenfield format frame must be able to detect that an HT Greenfield
format frame is an HT transmission (as opposed to a non-HT transmission). In this case
the receiver must decode the high throughput signal (HT-SIG) in the packet header and
determine if the HT-SIG cyclic redundancy check (CRC) passes. (Default: Mixed)
• HT Channel Bandwidth – The Multimedia Router provides a channel bandwidth of 40
MHz by default giving an 802.11g connection speed of 108 Mbps (sometimes referred
to as Turbo Mode) and a 802.11n connection speed of up to 150 Mbps. Setting the HT
Channel Bandwidth to 20 MHz slows connection speed for 802.11g and 802.11n to 54
