The Wireless Tab
Wireless-N ADSL2+ Gateway
The Advanced Wireless Settings Tab
This tab is used to set up the Gateway’s advanced wireless functions. These settings should only be adjusted by
an expert administrator as incorrect settings can reduce wireless performance.
Advanced Wireless
•
AP Isolation. This isolates all wireless clients and wireless devices on your network from each other. Wireless
devices will be able to communicate with the Gateway but not with each other. To use this function, click
Enabled
. AP Isolation is disabled by default.
•
Authentication Type. The default is set to
Auto
, which allows either Open System or Shared Key
authentication to be used. Select
Shared Key
if you only want to use Shared Key authentication (the sender
and recipient use a WEP key for authentication).
•
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the
Gateway can transmit. The Gateway will advertise its Basic Rate to the other wireless devices in your
network, so they know which rates will be used. The Gateway will also advertise that it will automatically
select the best rate for transmission. The default setting is
Default
, when the Gateway can transmit at all
standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are
1-2Mbps
, for
use with older wireless technology, and
All
, when the Gateway can transmit at all wireless rates.
•
Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless
network. You can select from a range of transmission speeds, or you can select
Auto
to have the Gateway
automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Gateway and a wireless client. The default setting
is
Auto
.
•
N Transmission Rate. The rate of data transmission should be set depending on the speed of your Wireless-N
networking. You can select from a range of transmission speeds, or you can select
Auto
to have the Gateway
automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Gateway and a wireless client. The default setting
is
Auto
.
•
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode’s default setting is
Auto
. The Gateway will
automatically use CTS Protection Mode when your Wireless-N and Wireless-G products are experiencing
severe problems and are not able to transmit to the Gateway in an environment with heavy 802.11b traffic.
This function boosts the Gateway’s ability to catch all Wireless-N and Wireless-G transmissions but will
severely decrease performance.
