24 Setting up your wireless router
When to use b only Mode–In some cases, older 802.11b clients may not be compatible
with 802.11g wireless. These adapters tend to be of inferior design and may use older drivers
or technology. Switching to this mode can solve problems that sometimes occur with these
clients. If you suspect that you are using a client adapter that falls into this category of
adapters, first check with the adapter vendor to see if there is a driver update. If there is no
driver update available, switching to b only mode may fix your problem. Please note that
switching to b only mode will decrease 802.11g performance.
QoS (Quality of Service) Configuration–QoS prioritizes important data on your network
such as multimedia content and Voice over IP (VoIP) so it will not be interfered with by other
data being sent over the network. Based on 802.11e, you can turn this feature on or off by
selecting it from the drop-down menu (3) and choosing the acknowledgement mode you
want to use. If you plan to stream multimedia content or use VoIP on your network, we
recommend that you enable the QoS feature.
Changing the Wireless Channel
There are a number of operating channels you can choose from. In the United States, there
are 11 channels. In Australia, the United Kingdom, and most of Europe, there are 13
channels. In a small number of other countries, there are other channel requirements. Your
Router is configured to operate on the proper channels for the country you reside in. The
default channel is 11 (unless you are in a country that does not allow channel 11). The
channel can be changed if needed. If there are other wireless networks operating in your
area, your network should be set to operate on a channel that is different than the other
wireless networks. For best performance, use a channel that is at least five channels away
from the other wireless network. For instance, if another network is operating on channel 11,
then set your network to channel 6 or below. To change the channel, select the channel from
the list, then click Apply Changes. The change is immediate.
Using the Broadcast SSID Feature
Note: This advanced feature should be employed by advanced users only.
For security, you can choose not to broadcast your network's SSID. Doing so will keep your
network name hidden from computers that are scanning for the presence of wireless
networks. To turn off the broadcast of the SSID, remove the check mark from the box next to
Broadcast SSID, then click Apply Changes. The change is immediate. Each computer now
needs to be set to connect to your specific SSID; an SSID of ANY will no longer be accepted.
Refer to the documentation of your wireless network adapter for information on making this
change.
Protected Mode Switch–As part of the 802.11g specification, Protected mode ensures
proper operation of 802.11g clients and access points when there is heavy 802.11b traffic in
the operating environment. When Protected mode is ON, 802.11g scans for other wireless
network traffic before it transmits data. Therefore, using this mode in environments with
HEAVY 802.11b traffic or interference achieves best performance results. If you are in an
environment with very little-or no-other wireless network traffic, your best performance will
be achieved with Protected mode OFF.
