[SOLVED] iwlist finds all other networks than mine

Hello fellow archers!

I've posted this in the Newbies corner as well, but realized this might be a more appropriate forum for this post...

I've been trying to set up Arch Linux on my laptop for a while now, but am completely stumped at the problem I've encountered.
My laptop is equipped with a Intel PRO/Wireless 5300 AGN draft-n wireless network card, and the drivers install just fine, however, the issue comes when trying to connect to my wireless network.
Upon first boot, I could connect to my network after setting up wpa_supplicant with the relevant info ( My network uses WPA2 - AES, broadcasting SSID, channel 9 ) immediately. I ran `pacman -Syu`, and installed all updates ( this also included an update to wpa_supplicant ). After a subsequent reboot, I went through the exact same procedure again ( only this time I had already set up wpa_supplicant.conf ) with

ifconfig wlan0 up
iwconfig wlan0 essid "<ESSID>"
sleep 10 # Just in case
wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant.conf

But this time, iwconfig does not associate with my AP.

I tried scanning for networks, and discover that it finds 15 different wireless networks, with all different channels and encryptions, but not mine!

I have tried everything I can think of, but my network does not appear in the scanning list..
The network works just fine on my desktop computer which is also running Arch Linux through a RaLink RT2870 right next to my laptop..

Anyone have any clue what might be going on?
Jon

you might have to install CRDA, Intel adapters seem extra fussy these days when it comes to wireless regulations..

Re: [SOLVED] iwlist finds all other networks than mine

Can we see your config file, just in case?

Also

$ wpa_cli status

might tell you something interesting (as increasing the debug level of wpa_supplicant).

Re: [SOLVED] iwlist finds all other networks than mine

Can we see your config file, just in case?

ctrl_interface=/var/run/wpa_supplicant GROUP=wheel
eapol_version=1
ap_scan=1
fast_reauth=1

And then the entry generated by wpa_passphrase..

Also

$ wpa_cli status

might tell you something interesting (as increasing the debug level of wpa_supplicant).

I've tried running wpa_supplicant with -dd, but still get no error messages, or hints of error messages.
As the computer with the problems has no internet, I can't post the output of it, but it seems completely normal.
wpa_cli status gave SCANNING as a result yesterday when I tried it, but now, it says that it cannot connect to wpa_supplicant, even though no errors occured when starting it, and the last line read Daemonizing... I can even see it in ps -ef...
I will try a reboot and see if I get it to work then..

CRDA

CRDA drivers?

Re: [SOLVED] iwlist finds all other networks than mine

Nope, even after a reboot, and running the exact same commands as yesterday, I still cannot connect to wpa_supplicant...

EDIT: I've tried running wpa_supplicant in non-daemon mode, and it seems that it is indeed running without problems, but it's just scanning for appropriate networks without finding any ( i.e. it finds all the others, but not mine )

EDIT2: I tried adding network={key_mgmt=NONE to /etc/wpa_supplicant.cont}, and it now immediately connected to one of the open networks in my neighbourhood, so it seems that the card and wpa_supplicant are at least working...

EDIT3: But wpa_cli still cannot connect to wpa_supplicant, even when I'm connected to an AP..?

Wow, CRDA made it work!
I just connected my laptop to the internet through a wire, and did

pacman -S crda

edited the file it says you should edit, added wireless-regdom to rc.conf daemons, rebooted, and voilla!

Thanks guys!
