>Description:
I am running FreeBSD 7.1 STABLE on IBM T40 machine. I have Intel(R) PRO/Wireless 2100 MiniPCI card.
bumper:bumper:~# dmesg | grep ipw0
ipw0: <Intel(R) PRO/Wireless 2100 MiniPCI> mem 0xc0210000-0xc0210fff
irq 11 at device 2.0 on pci2
ipw0: Ethernet address: xx:xx:xx:xx:xx:xx
Connection was tested using WinXP with AR5005G card.
Problems description:
Problem no. 1
--------------------------------------------
Driver is loaded, ipw0 interface can be found, adhoc
connection established without encryption -> WinXP/AR5005G shows CRC
errors when receiving data from FreeBSD/ipw0, it means that I have
associated status in ifconfig ipw0, WinXP/AR5005G shows established
connection (very good level of radio signal), no packets can be sent
or received.
my /boot/loader.conf
if_ipw_load="YES"
wlan_load="YES"
firmware_load="YES"
legal.intel_ipw.license_ack=1
ipw_bss_load="YES"
ipw_ibss_load="YES"
ipw_monitor_load="YES"
Above problem can be solved by changing /boot/loader.conf as follows
if_iwi_load="YES"
wlan_load="YES"
firmware_load="YES"
legal.intel_iwi.license_ack=1
legal.intel_ipw.license_ack=1
iwi_bss_load="YES"
iwi_ibss_load="YES"
iwi_monitor_load="YES"
iwi driver loads correctly, dmesg shows the same ipw0 Intel(R)
PRO/Wireless 2100 MiniPCI card, now connection works properly.
Problem no. 2:
--------------------------------------------
ipw / iwi needs to be restarted to work properly
- FreeBSD/ipw0 is connected to WinXP/AR5005G (adhoc mode)
- I close the connection shutting down WinXP (or disabling AR5005G
radio interface), FreeBSD/ipw0 stays untouched
- I start again AR5005G on WinXP
- connection seems to be established (signal level is good), but no
packets can be sent or received
Workaround solution is to restart ipw0 interface
ifconfig ipw0 down
ifconfig ipw0 up -> connection works properly
Problem no. 3:
--------------------------------------------
Sometimes, after ifconfig ipw0 (up/down/inet/etc..)
command, kernel panics

I have been running IBM T40 (Intel(R) PRO/Wireless 2100 MiniPCI) for
three years with WinXP, everything was fine. I am almost sure this is
not a hardware issue.
