Wireless Not working on HP Mini 110
After exhausting all other resources, I am here to ask of all your assistance. Here's my dilemma, short and simple: I can see a list of wireless networks, but when I click connect, it spins for about a minute and shows me disconnected. Here's my details, maybe you can make better progress than me.
Version Code:
Ubuntu 9.10 UNR Code:
2.6.31-19-generic Code:
*-network Code:
01:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) Code:
[ 3.731171] b43-pci-bridge 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 |
Hi -
You've made an effort to include good information - thank you. Unfortunately, it's still not enough to determine exactly what you're trying (there are several different routes you could be going), or exactly what's going wrong (driver level? 802.11 level? DHCP or DNS level? etc etc) STRONG SUGGESTION: Please look at this troubleshooting guide - I think it might help: https://help.ubuntu.com/community/Wi...eShootingGuide |
I believe it is a driver issue. It worked fine until I updated to 2.6.32-19 from 2.6.32-17. I just switched back to 17 though and the problem is still there. Any information you need feel free to ask. I'm lost.

Did you install firmware for the b43 driver? It doesn't work unless you do and Ubuntu can't distribute it directly, you'll probably need to use one of the unrestricted repositories.
That said, Broadcom's driver should work with that chipset. There is a bug at the moment, but if you read this link it isn't difficult to solve. |
First, I would like to think your for your assistance and ask in advance your forgiveness because I know when this is all said and done it will be something simple. Here's where I am:
I downgraded back to kernel revision 17, and installed bcmwl-kernel-source. Using network manager, I see a list of networks and attempt to connect to mine. The icon spins for about a minute and says "Acquiring network address". Then it shows "Wireless network disconnected", and the list of wireless networks disappears So, what can I do to pinpoint where the problem lies? |
Hi -
With all due respect (and as you're already very aware), the problem can be in one (or more) of several different places. You just have to start at the "bottom" and work your way up. 1. This link honestly seems to be a good troubleshooting guide: Ubuntu Wireless Troubleshooting Guide 2. You've already done a great deal of this work (at least through step 4, it looks like). I assume step 5 (iwconfig) does *not* work. If not, it might be useful to cut/paste specific error messages you're getting. 3. But you also said: a) it *used* to work (before you upgraded the kernel) b) you have the kernel source (good!) ... and ... c) you're getting many "dmesg" errors like this: Quote:
So definitely try: a) Uninstalling your current bt43 driver b) Updating your kernel headers and/or kernel source (make sure they're in synch with your running kernel) c) Updating your bt43 driver source (probably OK as-is: but why not double-check) d) rebuilding the driver (latest/greatest bt43 source with latest/greatest kernel source) <= *Definitely* cut/paste any errors you encounter! e) try installing the new driver <= Again, cut/paste any errors you encounter! f) See if you can get past step 4) in the Troubleshooting Guide 'Hope that helps .. PSM |
OK So I made a little progress:
I discovered part of the problem was excessive blacklisting. I got rid of everything and did a fresh driver install and that got rid of the dmesg errors. I tried to connect via command line and this is what happened: Code:
:~$ sudo ifconfig wlan1 down Any ideas? |
configuration: broadcast=yes driver=b43 driverversion=2.6.31-19-generic firmware=N/A link=no multicast=yes wireless=IEEE 802.11bg
One question - B43 needs firmware - but from the output: firmware=N/A Please check if you have it and if this driver needs it. |
OK So I attempted to install firmware and apparently I'm not doing it right. How should I go about this?
|
You need to download it and put to appropriate place where driver will read it.
But are you sure you need it. Please do: modprobe -r b43 modprobe b43 dmesg | tail -n 30. Please post outputs Thanks. |
So, I managed to get it working with a combination of tutorials. First I updated to kernel 2.6.32. Then I followed this tutorial http://ubuntuforums.org/showthread.php?t=1266620
However, The problem lay in this command: Code:
echo "options b43 pio=1" | sudo tee -a "/etc/modprobe.d/b43-thingy.conf" |
