DESCRIPTION
Set the channel depending on your particular region.
Select a channel or use Auto to have the VDSL Router automatically determine a channel
to use. Changing the channel may help resolve wireless interference issues. Use a channel
as many channels away from any channels used by neighboring APs as possible. The VDSL
Router's current channel number displays next to this field.
Select Auto to have the VDSL Router automatically use IEEE 802.11n to connect IEEE
802.11n clients. Disable this to not use IEEE 802.11n.
This displays when you set 802.11n/EWC to Auto.
Select whether the VDSL Router uses a wireless channel width of 20MHz or 40MHz.
A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz
channel uses two standard channels and offers speeds of up to 300 Mbps.
40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. The wireless clients must also support 40 MHz. It is often better to use the 20
MHz setting in a location where the environment hinders the wireless signal.
Select 20MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
This displays when you set 802.11n/EWC to Auto.
This is available for some regions when you select a specific channel and set the Bandwidth
field to 40MHz. Set whether the control channel (set in the Channel field) should be in the
Lower or Upper range of channel bands.
This displays when you set 802.11n/EWC to Auto. Select Auto to have the wireless
devices transmit data after a RTS/CTS handshake to help prevent collisions in mixed-mode
networks (networks with both IEEE 802.11n and IEEE 802.11g or IEEE 802.11b traffic).
Select Off to disable 802.11n protection. This can increase throughput in an IEEE 802.11n-
only environment although it may reduce transmission rates if your network also has IEEE
802.11G and IEEE 802.11B clients.
Select a transmission speed for wireless multicast traffic.
This is the maximum data fragment size that can be sent. Enter a value between 256 and
2346.
Data with its frame size larger than this value will perform the RTS (Request To Send)/CTS
(Clear To Send) handshake.
Enter a value between 0 and 2347.
This displays when you set 802.11n/EWC to Disabled.
Select 54g Auto to allow both IEEE 802.11G and IEEE 802.11B clients to connect.
Select 54G Performance for the best performance with IEEE 802.11G-certified clients.
Select 54G LRS (Limited Rate Support) to allow older IEEE 802.11B clients with 3-Bit
message headers to connect. Only use this if none of the other modes work.
Select 802.11b Only if all your wireless clients only support IEEE 802.11B.
This displays when you set 802.11n/EWC to Disabled. Select Auto to have the wireless
devices transmit data after a RTS/CTS handshake to help prevent collisions in mixed-mode
networks (networks with both IEEE 802.11g and IEEE 802.11b traffic).
Select Off to disable 802.11g protection. Only select this if you only connect IEEE 802.11G
clients.
