RTnet rt2500 WLAN README
|
========================
|
|
See http://www.fsf.org/resources/hw/net/wireless/cards.html
|
for a list of cards which use the rt2500 chipset.
|
|
After the modules rt_rt2x00core and rt_rt2500pci have been loaded the driver
|
can be configured with rtiwconfig. Following features are currently implemented
|
(see also rtiwconfig --help):
|
|
* bitrate: The committed value is multiplied with 0.5 Mbit/s.
|
Valid is 2, 4, 11, 22 for 802.11b and
|
12, 18, 24, 36, 48, 72, 96, 108 for 802.11g.
|
|
* channel: Sets frequency/channel. Channel IDs are from 1 to 13.
|
|
* txpower: Sets the transmission power. Zero means minimum TX power.
|
|
* retry: The hardware can be configured to do transmission retries.
|
This sets the maximum amount of retries.
|
|
* tx mode: The RTnet driver can be used in three different modes:
|
|
"raw": No acknowledgement of transmitted frames is expected.
|
-> No retries possible.
|
Target address of WLAN frame is set as passed from higher layers.
|
|
"ack": Acknowledgement of every transmitted frames is expected.
|
-> Retries are possible.
|
Target address of WLAN frame is set as passed from higher layers.
|
WARNING: This is currently only useful for unicast transmission.
|
|
"mcast": No acknowledgement of the frame is expected.
|
Receiver address of the WLAN frame is the own MAC-Address with group
|
bit set.
|
|
* drop broadcast: Configures, whether the hardware shall drop received
|
broadcast frames.
|
|
* drop multicast: Configures, whether the hardware shall drop received
|
multicast frames.
|
|
* bbp sensibility: Sets the receiving sensibility of the base band processor.
|
Values around 70 seem to be useful.
|
|
* autoresponder: Determines, whether the hardware responds automatically on
|
received unicast frames with an ACK frame.
|
|
* regread/regwrite: Gives direct access to the chipset registers.
|
Only useful if you know what you are doing :)
|
|
The driver has been tested with an ASUS WL-107g PCMCIA and a MSI PC54G2 PCI
|
card.
|
|
KNOWN BUGS:
|
After configuring the bitrate via rtiwconfig the driver activates the
|
hardware autoresponder. If desired, the autoresponder has to be disabled again
|
manually.
