Wireless unstable (intel 3945)

Hi, I have an Intel 3945 wireless, I use the wpi driver, and it disconnects quite often.

dmesg shows me a lot of "Beacon miss":

Code: 
Beacon miss: 20 >= 7
[...]
Beacon miss: 281 >= 7
ifa_del_loopback_route: deletion failed
ifa_del_loopback_route: deletion failed
wpi0: need multicast update callback
wpi_newstate: RUN -> INIT flags 0x0
wlan0: link state changed to DOWN

(here it's when I do /etc/rc.d/netif restart, I believe)

wpi0: timeout resetting Tx ring 3

wlan0: link state changed to UP

Here the lspci output on Linux:

Code: 
05:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

I have no problem with Linux.

Code: 
# uname -a
FreeBSD  8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #0: Tue Jan  5 16:02:27 UTC 2010     root@i386-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  i386

What can I do?
 
Hi,
I don't know about your problem, sorry, but I'm very interessed to know how you've configured your wifi.
I've installed a bsd on a laptop with the same wireless card as you but i don't arrived to configured the wireless
Can you shwo your /etc/rc.conf and your /boot/loader.conf ?
Do you use WPA or WEP ?

Very thx !

Cyrille
 
Again,
I solve my problem with a new installation of freebsd 8.0
I choose this time WPA against WEP and all is fine, no problem of connection
Connection is stable,
Cyrille
 
Hi cyrille,

I am sorry, I did not check this message in time, but I am glad to see you found a solution to your problem.
Since I still have the problem, I would ask you the opposite, so can you show me the files you wanted me to show you :-?

Here are mine:

/etc/rc.conf
Code: 
# -- sysinstall generated deltas -- # Sun Apr  4 13:50:45 2010
# Created: Sun Apr  4 13:50:45 2010
# Enable network daemons for user convenience.
# Please make all changes to this file, not to /etc/defaults/rc.conf.
# This file now contains just the overrides from /etc/defaults/rc.conf.
keymap="fr.iso.acc"

wlans_wpi0="wlan0"

ifconfig_wlan0="ssid my-ssid DHCP"

/boot/loader.conf
Code: 
if_wpi_load="YES"

(I am using an open wireless network).

Thank you.

Maybe no one even contacted him in that case (or other OpenBSD developers), but taking that apart, code of OpenBSD is ready to get, so that is why I assume why no one tried to fix this, propably lack of manpower, maybe other things are more important.
 
Well, if you guys are talking about beacon misses, then yes, OpenBSD has a solution for that. Ignoring it, that indeed works ;)

I hope to finally get a 3945 card.. should arrive next week. If time permits I'll try to find a fix.
 
I uplinked through DSL when the modem fried. Meanwhile to get from my desk back to FreeBSD forums I used ipnat to NAT my packets out through my Levono R61 via the Intel 3945. Whats lame in 8.0 stable is only seeing two access points with the Intel, while Atheros in the R61 shows ten! And then mysterious link drops while other wifis are going strong. Needless to say I made atheros on wlan1 my default router. Me and my homies have stayed lit up steady ever since.
