Planet Technology WNL-U552 Network Card User Manual


 
- 12 -
Network Type Infrastructure – This operation mode requires the presence of an
802.11 Access Point. All communication is done via the Access Point or
Router.
Ad-Hoc – Select this mode if you want to connect to another wireless
station in the Wireless LAN network without through an Access Point or
Router.
TX Power If you want to lower the transmit power of the card for saving the power of
the system, you can select the lower percentages from the list. The lower
power will cause the lower signal strength and the coverage range.
Ad Hoc Wireless Mode When the card is set in Ad Hoc (Peer to Peer Mode), you can designate
the wireless connection mode for the Ad Hoc network.
802.11 B only – This card can be compatible with both 802.11g and
802.11b wireless stations. If there are only 802.11b wireless stations in
the network, you can set the card to this mode.
802.11 B/G mix – If you have a mix of 802.11b and 802.11g wireless
stations in your network, it is recommended to setting the card to this
mode. This mode is also the default setting.
802.11 G only – This card can be compatible with both 802.11g and
802.11b wireless stations. If there are only 802.11g wireless stations in
the network, you can set the card to this mode.
Preamble The preamble defines the length of the CRC block for communication
among wireless devices. This option is only active in the Ad Hoc network.
There are two modes including Auto and Long Preamble. If “Auto“mode
is selected, the card will auto switch the preamble mode depending on
the wireless devices the card is connecting to.
RTS Threshold Minimum packet size required for an RTS (Request To Send). For
packets smaller than this threshold, an RTS is not sent and the packet is
transmitted directly to the wireless network. Select a setting within a
range of 0 to 2347 bytes. Minor change is recommended.
Fragment Threshold The value defines the maximum size of packets; any packet size larger
than the value will be fragmented. If you have decreased this value and
experience high packet error rates, you can increase it again, but it will
likely decrease overall network performance. Select a setting within a
range of 256 to 2346 bytes. Minor change is recommended.
