Chapter 3: Configuration
TP-LINK Wireless Adapter TL-WN510G/TL-WN550G/TL-WN551G can be configured by
TP-LINK Wireless Client Utility (TWCU). This chapter describes how to configure your
TP-LINK Wireless Adapter for wireless connectivity on your Wireless Local Area Network
(WLAN) and use the data security encryption features.
After Installing the Adapter, the Adapter’s tray icon will appear in your system tray. It
appears at the bottom of the screen, and shows the signal strength using color and the
received signal strength indication (RSSI).
If the icon is gray, there is no connection.
If the icon is red, there is poor signal strength and the RSSI is less than 5dB.
If the icon is yellow, there is poor signal strength and the RSSI is between 5dB and
10dB.
If the icon is green, there is good signal strength and the RSSI is between 10dB
and 20dB.
If the icon is green, there is excellent signal strength and the RSSI is more than
20dB.
Double-click the icon and the TWCU utility will run. You can also run the utility by clicking
the Start>Program>TP-LINK>TP-LINK Wireless Client Utility. The TWCU utility provides a
complete and easy to use set of tools to:
¾Display current status information

3. Edit the Advanced tab
¾Power Save Mode -
•Maximum -Selects maximum mode to let the access point buffer incoming
messages for the wireless adapter. The adapter will detect the access point if
any messages are waiting periodically.
•Normal - In Normal mode, the adapter will be switched to maximum mode
automatically when no large packets are retrieved.
•Off - turns power saving off, thus powering up the wireless adapter continuously
for a short message response time.
¾802.11b Preamble: Specifies the preamble setting in 802.11b. The default setting is
Short & Long (access point mode), which allows both short and long headers in the
802.11b frames. The adapter can only use short radio headers if the access point
supports and uses them. Set to Long Only to override allowing short frames.
¾Wireless Mode: Specifies 2.4 GHz 54 Mbps or 2.4 GHz 11 Mbps operation in an
access point network. The wireless adapter must match the wireless mode of the
access point with which it associates.
¾Wireless Mode when Starting an Ad Hoc Network: Specifies 2.4 GHz 54/11 Mbps
to start an Ad Hoc network if no matching network name is found after scanning all
available modes. This mode also allows the selection of the channel the wireless
adapter uses. The channels available depend on the regulatory domain. If the
adapter finds no other ad hoc adapters, the channel that the adapter starts the ad hoc
network with will be selected automatically. The wireless adapter must match the
wireless mode and channel of the clients it associates.
¾802.11 Authentication Mode: Select which mode the wireless adapter uses to
authenticate to an access point:
•Automatic causes the adapter to attempt authentication using shared, but
switches it to open authentication if shared fails.
•Open System enables an adapter to attempt authentication regardless of its
WEP settings. It will only associate with the access point if the W EP keys on
both the adapter and the access point match.
•Shared-key only allows the adapter to associate with access points that have
