Wireless recognized during install but not after

Hi guys,

I just installed Archlinux using my wireless network (i've installed ANYTHING, no drivers, no firmwares). Everything gone fine but after the installation I rebooted my system and... SURPRISE! The system couldn't bring up the wlan0 interface (recognized by ifconfig -a) because of: SIOCSIFFLAGS: No such file or directory

So after investigating, I found that I need the ralink driver. In fact, I've downloaded it and putted in /lib/firmware

Now I can bring up my IF but when I use THE SAME wpa_supplicant.conf file used during install, nothing, it doesn't work.

If you need more details tell me, but first of all... WHY during the install everything went fine and after no?! Is it a bit strange... no?

Thanks all

(using Archlinux x64 on Acer 5735z)

Re: Wireless recognized during install but not after

At least for rt2870sta, it's a retarded bug in Linux that was introduced in 2.6.31 and is still not fixed. It works in the live environment because it has an older kernel.

Kernel 2.6.31 module conflicts

The 2.6.31 kernel caused the rt2870 driver to conflict with other wireless modules. The fix in this thread says that you need to blacklist the rt2800usb rt2x00usb and rt2x00lib modules by modifying the MODULES array in /etc/rc.conf

MODULES=( ... !rt2800usb !rt2x00usb !rt2x00lib ... )

Simply: THANKS

Now I've a little problem, when I restart my system the NETWORK daemon FAIL

I've to run WPA_SUPPLICANT and then I'm connected. How can I see what fails?

You should use Netcfg, if you want to start wpa_supplicant at boot: http://wiki.archlinux.org/index.php/Wpa … Management

Re: Wireless recognized during install but not after

JohannesSM64 - it's not a bug. Users are offered a choice of driver, the original staging driver, and the official rt28xx driver. The rt28xx should be preferred, but is not mature enough yet to replace the staging driver completely. Ultimately, rt28xxsta will become obsolete, and all users will be able to use rt28xx. In the meantime, users select the driver they want to use and blacklist the other one, as advised.
