Lost wireless after reboot

[djmoore85]

Alright. I had everything workin just fine, had decent download speeds and such, now I have no wireless after I rebooted last week. Here is the output for:

Any help or suggestions on where to go from here?

[jglen490]

Open a konsole and show us the following:

What's the output from
sudo lspci -v?

And

What's the output from
sudo lsmod?

That will help determine which model Broadcom chip your wifi uses and whether or not the b43-fwcutter package might serve you better.

It may also be the wpa_supplicant is not correctly set up.

[djmoore85]

Here is lspci -v for network stuff

Except for the card maker, your Broadcom card is identical to mine

02:00.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)

I've had really good response from mine by using the b43-fwcutter package rather than ndiswrapper. I installer b43-fwcutter via Adept. It installed the packeage, obtained and installed the firmware file, setup knetworkmanager, and kwallet. Kwallet asks for and reatins a password to be used to activate the wifi connection upon boot. You will first need to uninstall ndiswrapper and ensure the module is removed. You probably don't have to, but it may be useful to blacklist the bcm43xx kernel module also.

b43-fwcutter gave me a very stable and responsive wifi connection.

[djmoore85]

Thanks for the suggestion, unfortunately it's a no go. When attempting to connect through wireless, I am being told no device active. But the power light for the card is on.

You are not alone! I had exactly this problem with a Broadcom card as posted in this thread:
http://kubuntuforums.net/forums/index.php?topic=3097464.0

I tried fwcutter, ndiswrapper and pretty much all the gui based config apps I could find in the repos. In the end, I gave up and reinstalled from scratch. It's been working perfectly since, but I still have no idea what really went wrong or how to cure it if this happens again.

[jglen490]

Did you uninstall the bcmwl5 driver via ndiswrapper and rmmod ndiswrapper itself? And did you try to blacklist the bcm43xx kernel module? That should have gotten rid of all that would interfere with the b43 driver and firmware.

I did remove the driver and ndiswrapper, but blacklisting anything is beyond my Linux knowledge. This is one I'm going to do some homework on though as it's not the first time I've had trouble with Broadcom and Linux.

Thanks,
Jim

[jglen490]

You'll find various "blacklist" files in /etc/modprobe.d, including one named "blacklist" ::). Blacklisting bcm43xx may not solve your problem, but I'm not sure why b43-fwcutter isn't working either, unless ndiswrapper has somehow shown up again. That can be checked with an
lsmod | grep 'ndiswrapper' command.

For me, KNetworkManager only kicks in during a Power-On - not after a reboot. ::)
And will ignore all your iwconfig, iwlist stuff. It just works - but only on a Power-On
