[SOLVED]strange!after pacman -Syu,dhcpcd wlan0 can't get IP .time out

I used to use these commands to connect to a AP

iwconfig wlan0 essid "CMCC-EDU"
ifconfig wlan0 up
dhcpcd wlan0

but after pacman -Syu upgrade,dhcpcd wlan0 can't get IP

dhcpcd[734]: version 5.5.6 starting
dhcpcd[734]: wlan0: waiting for carrier
dhcpcd[734]: timed out

then I try to do these

modprobe -r ath9k
modprobe ath9k nohwcrypt=1
iwconfig wlan0 channel auto
iwconfig wlan0 essid "CMCC-EDU"
ifconfig wlan0 up
dhcpcd wlan0

But do not work..
In windows 7 the card work well.CMCC-EDU has no problem.
I tried to use a USB wireless card (Realtek Semiconductor Corp. RTL8187 Wireless Adapter),but it has the same problem.

Some infomation maybe useful

Re: [SOLVED]strange!after pacman -Syu,dhcpcd wlan0 can't get IP .time out

And I can use

airmong-ng start wlan0
airodump mon0

to do some hack......

I still stop at "dhcpcd wlan0"....

This is a known issue in the 3.3 kernel. See this BR for more info.

Re: [SOLVED]strange!after pacman -Syu,dhcpcd wlan0 can't get IP .time out

Try this:
1º sudo pacman -S linux-headers
2º wget http://wireless.kernel.org/download/com … .6.tar.bz2
3º tar jxvf compat-wireless-2.6.tar.bz2
4º cd compat-wireless<tab>
5º make
6º sudo make install
7º sudo make unload
8º Reboot and try...
If it doesn't resolve the problem do:
cd compat-wireless<tab>
sudo make uninstall and reboot
OBS: This worked for me. Hope for the best. My Wireless Card uses the ath9k and there as a regression on kernel 3.3.1. I think that there are a regression on ath* modules

Re: [SOLVED]strange!after pacman -Syu,dhcpcd wlan0 can't get IP .time out

Works for me, thank you Igeek !

I had to install the linux-header package first.->  http://www.archlinux.org/packages/core/ … x-headers/

(download from another computer and copied to the directory /var/cache/pacman/pkg/ )

Compilation lasted 30 minutes.

Yes, I forgot to put linux-headers as a needed package. Glad that worked for you

I'm having the same problem since the kernel upgrade. I installed the LTS kernel and have booted with that, but I still can't connect to any wireless networks. :-(

If you can't connect with the LTS kernel than you have a different issue, look what else got upgraded at the same time and if necessary post your own thread.

That trick worked for me. Thank You! I read that the new kernel 3.3.2 has this issue fixed. Should I uninstall this fix before upgrading to the new kernel when it comes out?

Works for me too, but I had to reboot my laptop before make and make install.
Thanks

Not necessary. When installing new kernel, all modifications made are overwritten by the new kernel. But if not sure, you can unninstall.

I'm running kernel 3.3.7-1, and this fix worked perfectly with ath9k. Thanks!

Re: [SOLVED]strange!after pacman -Syu,dhcpcd wlan0 can't get IP .time out

I didn't try this, but am on the arch standard x86_64 kernel, 3.6.3-1. Above it seems that kernel 3.3 should have fixed this, but I'm still having an issue. Should I even try this, or if kernel 3.6 isn't doing it for me do I have a separate/different issue?
