B43 randomly and silently dropping connections...

[Jerry McBride]

The story is...

I've moved from 2.6.25.x using BCM43XX with a Broadcom 4306 (rev3) 802.11 
chipset to 2.6.26.6 using the B43 and appropriate firmware. This on a COMPAQ 
Presario R3000 P4 and  a gig of memory and ATI graphics.

I followed the install (upgrade) directions at linuxwireless.org. Piece of 
cake! However... I find that I've gone from "bulletproof" BCM43XX wifi 
connections to "bullethole" connections with B43.  

Under the old BCM43XX the handshake and connections were flawless and 
unfaltering. Now with the new B43, handshakes with AP's are perfect, but the 
connections randomly and silently fail. There are no debug messages, no 
complaints what-so-ever in /var/log/messages... 

To gt wireless back, I have to reinitialize the connection. I've gotten so 
good at it, that I can recite by heart the appropriate commands...

It's killling me! I've got to get this ironed out... it's not just my laptop, 
it's happening quite regularly with people I know with similar chips and 
laptops.

Trying 2.6.27-rc's and now 2.6.27 and the situation is no better.

So I ask... Who is the B43/B43LEGACY maintainer and would you be interested in 
debugging this mess? I'll bend over backward to help you... Email me 
direct... I'm very willing.

SHORT STORY:
-- Kernel 2.6.25.x with BCM43XX, firmware 4.80.53.0.. just perfect.

-- Kernels 2.6.26 or higher with B43 and firware 4.150.10.5 good negotiations, 
but fragile connections that drop randomly and without complaint. B43LEGACY 
does nothing.

Any help would be appreciated. I'd really like to get this ironed out. I 
highly desire to use current kernels.

Feel free to email me direct.

Yes I can confirm this problem.
I have bcm4318 card and my connection frequently and unexpectidely is 
dropping with b43 (I had no problem with bcm43xx module). It did not 
differ at all which firmware I used.
dmesg gives:

What kernel version? There have been a number of recent changes in mac80211 that
make connections a lot more robust. If you are not running 2.6.27, I suggest
getting it, or (even better) a copy of wireless-testing.

B43 randomly and silently dropping connections...

[Jerry McBride]

The story is...

I've moved from 2.6.25.x using BCM43XX with a Broadcom 4306 (rev3) 802.11 
chipset to 2.6.26.6 using the B43 and appropriate firmware. This on a COMPAQ 
Presario R3000 P4 and  a gig of memory and ATI graphics.

I followed the install (upgrade) directions at linuxwireless.org. Piece of 
cake! However... I find that I've gone from "bulletproof" BCM43XX wifi 
connections to "bullethole" connections with B43.  

Under the old BCM43XX the handshake and connections were flawless and 
unfaltering. Now with the new B43, handshakes with AP's are perfect, but the 
connections randomly and silently fail. There are no debug messages, no 
complaints what-so-ever in /var/log/messages... 

To gt wireless back, I have to reinitialize the connection. I've gotten so 
good at it, that I can recite by heart the appropriate commands...

It's killling me! I've got to get this ironed out... it's not just my laptop, 
it's happening quite regularly with people I know with similar chips and 
laptops.

Trying 2.6.27-rc's and now 2.6.27 and the situation is no better.

So I ask... Who is the B43/B43LEGACY maintainer and would you be interested in 
debugging this mess? I'll bend over backward to help you... Email me 
direct... I'm very willing.

SHORT STORY:
-- Kernel 2.6.25.x with BCM43XX, firmware 4.80.53.0.. just perfect.

-- Kernels 2.6.26 or higher with B43 and firware 4.150.10.5 good negotiations, 
but fragile connections that drop randomly and without complaint. B43LEGACY 
does nothing.

Any help would be appreciated. I'd really like to get this ironed out. I 
highly desire to use current kernels.

Are you running a distro kernel?  Or one you have built yourself?

If the latter, have you opened a bug at bugzilla.kernel.org?
Otherwise, have you opened a bug with your distro's bug tracking
system?

Do you have wireshark captures taken with another device in monitor
mode that show these connection drops?

Are you using NetworkManager or wpa_supplicant?  Or just configuring
your connection with iwconfig?  If the latter, consider the former.
If you are using NM, does the connection get re-established
automatically?  Or is NM unable to reestablish the connection?
Use wpa_supplicant directly if NM just doesn't work for you.

It seems clear that posting the same message to the mailing lists
again and again is not resolving the issue for you.  Please perform
the actions requested above (including opening a bug at the appropriate
place) and collect some useable data for us.

Thanks,

John

In addition, have you tried updated firmware that was pointed to
http://thread.gmane.org/gmane.linux.kernel.wireless.general/22790

No idea if it will fix it or not.
