	and
http://ipw2200.sourceforge.net

NOTE: Both adapters are covered at this site.


Incorrect RTS/CTS mechanism plus fragmentation behaviour
-----------------------------------------------------
When Intel PRO/Wireless 2915ABG Network Connection driver for Linux does
fragmentation, RTS is sent before the first fragment for most packages.
But sometimes RTS will be sent before each fragment.

Defect: #391


Problem with fragmentation and encryption in a noisy environment
------------------------------------------------------
Transmission problems are found randomly when using the driver with
fragmentation and encryption enabled together in a noisy environment.

Workaround: Disable fragmentation by "iwconfig eth1 frag off"


ICMP6 router advertisements can not get through randomly
------------------------------------------------------
ICMP6 packets can not get through Intel PRO/Wireless 2915ABG Network
Connection driver for Linux sometimes.

Workaround: Running this command "iwpriv eth1 sw_reset" can fix this problem

Defect #810


Wireless tool interaction
------------------------------
The following wireless tools operations are not yet supported by the
driver:

Currently there is no support for changing the sensitivity threshold
for the signal levels.
Defect:  #500

Currently the noise level is always -256dBm in IBSS mode.
Defect: #694


802.1x:
------------------------------
Supporting 802.1x is still lacking in  certain versions of xsupplicant, AP models.
Defect: #258


Firmware error in monitor mode
------------------------------
Sometimes there is firmware error in monitor mode: SYSASSERT 0x0000038f.

Workaround:
	Download ipw2200-fw-2.3 from http://ipw2200.sourceforge.net/firmware.php?fid=5.
	Unpack ipw2200-fw-2.3.gz in the directory that ipw2200-fw.2.4 is located.
	Delete all ipw2200-fw-2.4 files. Change the name of ipw2200-fw-2.3 files to 
		ipw2200-fw-2.4
	Reload Intel PRO/Wireless 2915ABG Network Connection driver for Linux.
