Karmic BCM4311 doesn't work with Broadcom B43 wireless driver and Driver Broadcom STA

[Tyrael]

Broadcom B43 worked the first time but stops working after reboot / halt.
I tried 2 different AP with both WEP. One result connected but only ping and few connection worked (other PCs connected to the same AP worked perfectly) the other gives authentication time out.

STA driver freeze sometimes the notebook and gives similar error.

With Ubuntu 9.04 the wireless card works.

I have the same issue. Please fix it before the final release.

[Steven Harms (sharms)]

I can confirm this also.

[LSL (spesialstyrker)]

Same problem on my dell e1705 laptop. BCM4311 wireless.

[evp55555 (evp55555)]

I don't know why, but I installed karmic again on the same machine (dell Inspiron 1520) , while it is connected to Ethernet, and now the Ethernet and wireless are working (after installing the non-STA driver. I will try the STA again and post here the results.

[LSL (spesialstyrker)]

I had the same experience on a fresh install and installing the fwcutter with the hard link up to fetch the firmware, but after the first reboot the wireless ceased to function. It would detect the networks available, but would not connect to either unencrypted or encrypted wireless network. Was a short lived victory :(

[swoody (swoody)]

I do not have this issue. I did a fresh install of Karmic Beta on my laptop which has a BCM4311, and the STA, b43, and openFWWF drivers all work fine without any issues that I've come across. I have connected to WPA and unencrypted networks without issue.

[hejkki (heikki-kniivila)]

it worked for me after a fresh install, but
after trying to share the connection from network manager -> create new wireless network...
all stopped working.

Even after i tried to remove the new connection that i made, nothing started working again.

[bernie eiben (b-eiben)]

Worked on ASUS 1000HE in pre-release of 9.10 [ although needed fiddling and only worked after about 5 trials ]

This netbook has a 'changed' wireless interface [BCM4311] to support Windoze, hacked OSX and linux - only Ubuntu Remix currently doesn't work..

[bernie eiben (b-eiben)]

 There's more wrong - I just rebooted and got the 'driver is authenticated' from the widget - but no sign that
wireless is supported, Then via 'right-click' on the ethernet-connection' I saw the 'connect to hidden networks' ,
which was the first clue, that things might work.. so I entered the 'hidden network' stuff' (SSID and pwd) and got
a connection. Only after disconnecting Ethernet, I finally see the Wireless picture on the top bar..

So in Summary - it's a 'step back' from the pre-release and is getting further away in comparison to Windoze and
MAC-OSX which directly connect [ no need for "sudo apt-get update" , "authentication" , entering a wireless network in the network widget and reboots ] .. and netbooks are currently high volume sales items ..

[semacore (surerank)]

I am using a n wireless card on a dell xps m1710.

It seems to happen when the computer is idle and then the driver becomes corrupt and won't reload.

I've done the following about 7 times... it's a temporary fix at best but does get you working ... until at least the computer goes idle.

1 - Add the Install CD to the software sources
2 - In Synaptic, locate the broadcomm sta package and mark for reinstall
3 - Reboot, go to Administration/Hardware drivers and hopefully now the wirelles driver is working.
4 - rinse and repeat

Could the issue be connected to the screen going dim when idle and not re-brightening bug?

[semacore (surerank)]

I should note that this was not an issue when I first "upgraded" from the stable 9.04 to the buggy 9.10

This problem was caused by one of the updates since the release which I took because I was trying to fix other issues.

The hardware I have worked fine under:
 - Ubuntu 8.04.3 LTS (Hardy Heron)
 - Ubuntu 8.10 (Intrepid Ibex)
 - Ubuntu 9.04 (Jaunty Jackalope)
 - Windows Vista

Is there a guide for downgrading to 9.04?

[semacore (surerank)]

seems to be fixed.

[semacore (surerank)]

Not fixed afterall.
Problem came back when laptop was left on and allowed to hibernate/sleep.
Not sure what one has to do with the other.

Could it be connected to the problem where the screen can't recover from being dimmed 50%?

[Night Eagle (nighteagle)]

Problem seems to be that since a recent update (approx 12/4/2009, guessing 2.6.31-16 kernel or modules), b43 driver initialized in "disabled" state rather than state at shutdown. I found a workaround: I'm able to "enable wifi" on my Dell Inspiron 1501 laptop via <Fn-F2> key once booted and then I get wifi as normal. Main problem here seems to be that the b42s always initializing in "disabled" state rather than "active" or prior state at shutdown. This previously worked fine in Jaunty and Karmic until applying a small batch of recent updates that included kernel 2.6.31-16.

Interesting was that falling back to an older kernel did not fix, at least not immediately, so maybe the problem is that "active" state is not being saved (so regardless of kerel booted, starts as inactive)? Need to try boot in older kernel, activate, shutdown, reboot in same old kernel to see if this theory is holds true.

[Night Eagle (nighteagle)]

This does look to be a change in behavior in the b43 driver.

With 2.6.31-16, I have to manually "turn on" wifi via <Fn-F2> keypress on my laptop. Upon keypress, kernel drivers are loaded and the interface is brought up.

With 2.6.28-16 and earlier, the kernel module is loaded the interface brought up automatically.

When I initially updated to Karmic w/ kernel 2.6.31-15, i'm pretty sure wifi via b43 worked fine, just as it did in 2.6.28. Problems started with recent update that included 2.6.31-16 kernel. However, when I test now, 2.6.31-15 behaves like 2.6.31-16 -- I have to manually "turn on" wifi.

This is a pretty brutal regression for anyone afflicted, but at least there is a easy workaround.

Here are some relevant log lines from bootup (when b43 fails to activate), then I press Fn-F2 and that activates the radio properly. Looks like maybe nw-manager is trying to bring up the interface before b43 has loaded firmware.

reboot:
