USB Wireless Lan Adapter has two modes, Infrastructure and Ad-Hoc. The default setting is Infrastructure.
(Please refer to the Product Introduction) Channel:
The channel setting should follow the regulation of the local government. For Infrastructure mode, the channel does not need to be set. It will automatically change to the same channel as APs. In Ad-Hoc mode, users can change the channel to match the connected computer. SSID:
When STA (WLAN Adapter) is in Ad-Hoc mode, all connecting STA should have the same SSID. When STA is in Infrastructure mode, the SSID will change to the same as APs SSID. 2 3 Important: Capital and non-capital are different words in SSID setting. 4 Tx Rate:
It determine STAs transmitting rate. There are 5 rated to choose, 1, 2, 5.5, 11Mbps, and Auto. The default setting is Auto. Int. Roaming:
Its default setting is Disable, and does not need to be adjusted. 5 6 Radio:
The default setting is ON. It means to stop the STAs RF function. If your WLAN Adapter is embedded, you can stop its function by turning the Radio ON. 7 Encryption:
USB Wireless LAN Adapter provides 64/128bits encryption. Choose disable, if you do not need this function. When using Encryption, there are two configurations to setting:
Choose from encryption key 1~4 to encrypt.
For 64bits encryption:
Using letters & numbers: 5 digits (a-z,A-Z,0-9) Hexadecimal: 10 digits (a-f,A-F,0-9)
For 128bits encryption:
Using letters & numbers: 13 digits (a-z,A-Z,0-9) Hexadecimal: 26 digits (a-f,A-F,0-9) USB Wireless LAN Adapter 13
Choose the Authentication type from open system, share key, and auto type. The default setting is auto. 8 PREAMBLE:
This function determines the PREAMBLE TYPE that physical layers PLCP will use. There are three modes to choose: LONG, SHORT, and AUTO. The default setting is AUTO, and the system will automatically choose the optimized mode. 9 Tx Power Level (mW): Does not open to change. 10 Fragmentation Threshold:
This configuration determines whether needs to fragment the Frame during transmit. When fragment, if the transmit fell, computer only resent the fell frame instead of the whole file again. When the frequency band used is not clear, i.e. The S/N ratio is low, transmit is easier to fell. Under this situation, fragmentation is a good way to increase efficiency. 11 RTS/CTS:
When frame smaller than the RTS Threshold value, the STA will automatically transmit the frame if the channel is available. If the channel is used, STA will follow the 802.11b regulation that would ask the receiving device whether to send the frame. This will take more time for devices to check with each other, but it also prevents the loss of frames. 12 Power Save:
Determine whether to use power saving mode. The default setting is Disable. ApplicationGAd-Hoc(peer to peer) mode setup Data sharing between computers without an AP When user does not want to have Ethernet line or want to share resources (including data and printers), using WLAN is the lowest cost solution!
