[Solved] Linux 3.0.6-1 disabled wifi

killgriff · 2011-10-05 23:01:59

After upgrading to the new kernel and rebooting the computer, I can't enable wifi. Ethernet works fine but I can't get wifi starting again. Tried restarting the network and networkmanager daemons. I also tried downgrading to 3.0.4 but it has already been taken out of the repos.

It might still be present in /var/cache/pacman/pkg.

P.S.: You need to be able to move ahead with kernels. That wireless thing is probably going to be easy to fix. Take a moment to describe the wireless chipset, the driver it had been using, and what you did to get it to work in 3.0.4-1. Also describe exactly what is wrong. Maybe somebody will be able to think of something for you to do.

Have you tried using iproute2 tools, wpa_supplicant and dhcpcd (or dhclient)?

If you want to downgrade, read https://wiki.archlinux.org/index.php/Do … g_Packages

Do you get any errors when trying to connect? Are the modules being loaded?

I had trouble with wifi when I upgraded to kernel 3.0 and did a fresh install with the new media so 3.0.4-1 wasn't in /var/cache/pacman/pkg.

I'm on a hp mini with a broadcom (forgot the model) chipset. The driver has been built into all of the previous kernels. I checked ifconfig and wlan0 shows up, but with dhcpcd, it won't connect. I use gnome-shell and network through the network manager applet. On the applet dropdown it shows wireless is off and just switching the toggle doesn't work. Opening network manager shows wireless as unavailable.

What is the security on your router? If your interface is up but dhcpcd can't connect you might not be associating with it correctly.

killgriff · 2011-10-06 00:12:10

Security is wpa2 - dhcpcd hangs on "waiting for carrier"

the sad clown · 2011-10-06 00:25:49

Have you tried restarting your router? Also, did you try using dhclient instead of dhcpcd?

killgriff · 2011-10-06 00:42:00

I've tried restarting the router and dhcpcd has the same error. i installed dhclient but it doesn't seem to be working, or at least I don't know how to use it.

Edit-
sudo dhclient gives me this error
/sbin/dhclient-script: line 131: hostname: command not found

please tell us your chipset:
root@blackout:~# lspci | grep -i network

killgriff · 2011-10-06 00:47:12

[killian@archlinux ~]$ lspci | grep -i network
01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

And here's my iwconfig in case it helps at all-
[killian@archlinux ~]$ iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=19 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

Try installing inetutils

We already have a bug report for dhcpcd https://bugs.archlinux.org/task/26117 + a related one for dhclient https://bugs.archlinux.org/task/26049

There are few commits between 3.0.4 and 3.0.6 that may be the culprit. We can try to revert them one by one.
First try is there:
http://ompldr.org/vYW9oeQ/revert_test.tar.bz2

$ sha1sum revert_test.tar.bz2
8ac5286d6042b31bbeafb85c8b178833564b4b71 revert_test.tar.bz2

just do the following, as root:
# tar xvjf /path/to/revert_test.tar.bz2 -C /lib/modules/3.0-ARCH/
# depmod -a

then reboot

Thank you @bangkok_manouel, but it turns out that it was not a problem with the kernel, but with network manager. I reinstalled wicd (what I used before network manager) and wifi is working fine. I would like to know how to get network manager working again though.

killgriff · 2011-10-06 05:50:11

Ok, I'm just an idiot. I was looking around on an ubuntu forum about network manager and most of them realized the hardware key for wifi was the culprit. The light was on my wifi key and wicd picked up the wifi so I ruled that out. I decided to try hitting it anyway, and within seconds network manager started right up and connected. Thanks for all the help guys, sorry it was such a simple fix.
