[SOLVED] dhcpcd timeout after update (wireless)

anadyr · 2012-04-05 22:30:08

Hi,

After several months I updated my laptop with pacman -Syu (407 new packages), and now DHCPCD fails over my wireless connection (not eth0). I connect through netcfg/net-profiles with the profile Wireless. The card us a Ralink RT2500 Wireless 802.11bg.

Does someone have an idea why it doesn't work? This is the various relevant configs and outputs:

profile Wireless wrote:

Try the workaround indicated in this thread (increasing the carrier timeout).

anadyr · 2012-04-06 06:39:53

For some reason the option CARRIER_TIMEOUT=60 is not read from my network profile. I set it to 60 seconds, but it uses a timeout of 10 seconds (as it still issues the command "dhcpcd -qL -t 10 wlan0"). Or should I set the option CARRIER_TIMEOUT=60 somewhere else?

Edit1: I added the option "timeout 60" to dhcpcd.conf, but netcfg still uses a dhcpcd timeout of 10 seconds...
Edit2: I now added DHCP_TIMEOUT=60 to my profile, and now netcfg does use 60 seconds. But unfortunately it does not solve the problem...

I didn't fix it yet. Here is the output of "iwconfig wlan0". Does this output give any indications why the last command "dhcpcd wlan0" timeouts?

I have the same problem. Or rather had. I updated my laptop after a few weeks (including kernel update) and wpa_supplicant would timeout , the option -ddt (maximum verbose) didn't give me any useful information. So I decided to compile and install an older version of the ath9k driver from compat-wireless. This solved the problem. So the update somehow breaks ath9k. Maybe it's the case for your driver too.

A convenient way to install your own driver is to use the package
https://aur.archlinux.org/packages.php?ID=41472
from AUR, the PKGBUILD file allows you to select the driver you want (uncomment a line in it) so that you don't spend 5 hours compiling useless stuff, it will take you 15 seconds. But maybe this is bad advice I am by no means an expert.

I also had a similar problem after an important update (long time).
I got a few gray hairs, then tried to reinstall the kernel (pacman -S linux)—and it did fix it.

anadyr · 2012-04-18 21:24:13

I still haven't been able to fix it; I am not able to bring up a wireless connection, also not in the latest kernel 3.3.2.
I also tried the solution suggested here, but that doesn't work either as it somehow disables the wireless switch ("RTNETLINK answers: Operation not possible due to RF-kill". The rfkill command doesn't change this and the physical wireless switch is not responsive). I haven't tried the AUR-version of compat-wireless, but I'll give it a try if there are no further suggestions.

To resume: the last working kernel was 2.6.31. Then the minimum kernel became 2.6.32 and I had to update. From then on wireless stopped working. It is a rather old laptop (about 2004 I think, a Twinhead E12BL).

I found the problem. I had an ndiswrapper.conf file in the /etc/modprobe.d with the line "alias wlan0 ndiswrapper". I really can't remember anymore why I had this, but I uncommented it and works again...

Edit: the problem returned soon after, so this wasn't the problem. Instead it turned out that it was the power saving function. I can connect now after turning this off (iwconfig wlan0 power off).
