asus eeepc 1000he - wlan0: carrier lost [Solved]

I read that wlan shoud work out of the box basic:

http://wiki.archlinux.org/index.php/Asus_Eee_PC_1000HE (Reference)

but still something goings wrong after connection to internet. I followed steps of Beginners' guide:

ifconfig wlan0 up
iwconfig wlan0 essid "default"
dhcpcd wlan0

I got ip address and I was able to ping www.google.com couple of times

, but then something broke the connection and I got full(100%) packets loss. After reboot computer and doing eveything again, same thinks happen: after couple of successfull ping I lost the connection

I used dhcpcd with the parameter -B and got following message : wlan0: carrier lost

I have following rows in the rc.conf (copy pasted from BG and added wlan0 interface):

HOSTNAME="hostname"
eth0="dhcp"
wlan0="dhcp"
INTERFACES=(eth0 wlan0)

I am very thankful if somebody can help me with this problem. Am I missing some important packets or what carrier lost means? (wireless_tools is installed)

once you lose your connectivity, check ifconfig to see if wlan0 is listed, this is so that you can find whether it is disconnecting from the AP or getting its IP released,

check /var/log/everything.log for info.

After command iwconfig wlan0 essid "default" I started to repeat command iwconfig, and made notice: at the begin it lists ESSID:"default" but after few second it disappears.

I found this interesting row from the /var/log/everything.log:

No probe response from AP 00:11:95:74:dd:ee after 500ms, disconnecting

I can see wlan0 interface all the time with command ifconfig.

I dowloaded and installed new rt2860 driver and firmware from the AUR, but it didn't help. If I try to get IP (dhcpcd -B wlan0) after disconnection, it says firstly: wlan0: waiting for

carrier and finally: timed out

Any ideas?

What is your lsmod output regarding rt* modules?
Is rt2860sta module loaded?
If you find some rt2x00pci and rt2x00usb modules loaded, you have to disable them in your /etc/rc.conf.

Thank you a lot!

Black listing those modules solved my problem. I also blacklisted rt2x00lib, which I found using lsmod. I needed to run command: iwconfig wlan0 essid on before ip-request and now my wlan works perfectly.

Cheers mates!
