Hi, i have installed Arch Linux on my computer but when a tried to connect to internet with my Ovislink Evo-w300pci chipset RT2760  i get this error when a type "ifconfig wlan0 up":

SIOCSIFFLAGS: No such file or directory

How can i solve it?

Re: RT2760 can't connect

lsmod | grep rt

modprobe -r nearly everything that have to do with rt and just do that

modprobe rt2x00pci

if it works put all the unloaded modules (except of rt2x00pci) to /etc/rc.conf with ! prefix to the modules area

//EDIT: also use ifconfig -a to make sure that it is wlan0 and not ra0 or something like that

Re: RT2760 can't connect

Hi:

I typed lsmod | grep rt
Then modprobe -r rt2860sta rt2800pci rt2800lib rt2x00usb rt2x00pci rt2x00lib
And Finally modprobe rt2x00pci

But now, wlan0 has dissapeared

Re: RT2760 can't connect

ok try this

modprobe -r rt2860sta rt2800pci rt2800lib rt2x00usb rt2x00pci rt2x00lib

for i in rt2800pci rt2800lib rt2x00pci rt2x00lib; do modprobe $i; done

if that works you have to blacklist rt2860sta and rt2x00usb

Re: RT2760 can't connect

With 2.6.34, you will need to install linux-firmware. And I'd try rt2860sta before rt2x00, more chance of success IMO.

Re: RT2760 can't connect

He meant actually executing the entire line at once :

for i in rt2800pci rt2800lib rt2x00pci rt2x00lib; do modprobe $i; done

Re: RT2760 can't connect

Nothing. Should I reinstall Arch and start from the beggining?

Problems with RT-Wireless Devices seems to get more and more common...

Re: RT2760 can't connect

Intel

Or that one: http://www.amazon.de/gp/offer-listing/B … dition=new

8,46 with shipping.

Works flawless under Linux from the first second but not that good under Windows (who cares)

Re: RT2760 can't connect

With eeepc's rt2860sta wireless driver, you've got to blacklist rt2800pci, rt2800usb, rt2x00pci and rt2x00usb, then modprobe rt2860sta to have wireless working (otherwise wireless networks are detected, but no association is enabled).

Edit your /etc/rc.conf, blacklisting the said modules in the MODULES part of the file:
...MODULES=(!rt2800pci !rt2800usb !rt2x00pci !rt2x00usb)...
Save it, then modprobe rt2860sta and you should have working wi-fi.

Edit: it's the same driver than 2860: Ralink PCI/mPCI/CB RT2760/RT2790/RT2860/RT2890 Driver 2.0.0.0
http://wiki.debian.org/rt2860sta
The rt2800 and rt2x00 are not really fully working yet, but are already implemented in Arch and Fedora, which can bring a few problems.

Re: RT2760 can't connect

I've had no problems at all with rt2870 since the drivers have moved to staging.

Nothing. Should I reinstall Arch and start from the beggining?

Nope, that won't change anything (generally in Linux you're discouraged from 'reinstall and hope for the best').

What I would do:

1) enable testing in /etc/pacman.conf
2) update with pacman -Syu
3) make sure linux-firmware is installed
4) make sure all rt2x00 and rt2800 modules are blacklisted in rc.conf
5) make sure rt2860sta is NOT blacklisted
6) reboot (which should have the same effect as rmmod && modprobe but is simpler to explain )
7) if connecting works, rejoice
8) else look in /var/log/everything.log for anything rt2860 / wireless related and post it here.

Re: RT2760 can't connect

im really against step 1

testing is for the guys who read the mailing list every day and people who can accept not to update when theres a rebuild of libjpeg or things like that.

he can download the 2-3 kernel packages by hand and pacman -U them

Re: RT2760 can't connect

Thanks for help schuay. Now my Archlinux recognizes my wifi card and i can do ifconfig wlan0 up and iwlist wlan0 scan
But i have a little problem:
I do iwconfig wlan0 essid "MYESSID" key s: MYASCIIKEY
It seems to be well connected but when i do pacman -Syu i have this error:
error: failed retrieving file "nameoffile.tar.gz" from ftp.rediris.es : Transient resolver failure

what can i do?

Re: RT2760 can't connect

sudo dhcpcd wlan0

And you might want to take a look at the wiki

Re: RT2760 can't connect

Check iwpriv/iwconfig in the link I posted (iwconfig doesn't work with this driver).

Get an ethernet cable for a few seconds and install either network-manager or wicd (detailled how-tos on the Arch wiki,  with step-by-step procedures).

Re: RT2760 can't connect

You need to provide some more info..  Is the access point WEP encrypted? Is it configured for dhcp or static ips? Are RX / TX Packets > 0 in 'ifconfig' after you connect?

That said, I agree it'd be much easier if you get an ethernet connection for a bit (if possible) and install a GUI network tool as oupsemma suggested. Or alternatively, maybe give Ubunut/other beginner friendly distros a try before moving to Arch.

Re: RT2760 can't connect

It has nothing to do with being an Arch beginner or not, it's this rt2860sta RaLink driver which is a real nightmare, in any distro you use (even Ubuntu).

After one year of distro-hopping with this eeepc and rt2860sta, I've experienced that the only Linux distro that is working flawlessly with it is Mandriva, where you get your wireless working with rt2860 with only a modprobe rt2860sta and there it goes.
( And in Unix, OpenBSD works with no tweaking at all).

The best way with Arch is to use the Ethernet to install one of these two GUI.
