I tried calling wpa_supplicant, providing the settings in the /etc/networking/interfaces file.<br/>In 1 out of 10 test I succeed, but I can't say what I did to make it succeed. I see the message "eth1 link is not ready" and sometimes it says "eth1 link becomes ready". Could you tell me what you did?<br/><br/>Thanks in advance,<br/><br/>katsi Hi,

I’m having the same problem which I couldn’t solve yet. I tried calling wpa_supplicant, providing the settings in the /etc/networking/interfaces file.
In 1 out of 10 test I succeed, but I can’t say what I did to make it succeed. I see the message “eth1 link is not ready” and sometimes it says “eth1 link becomes ready”. Could you tell me what you did?

Thanks in advance,

katsi

Is the router leasing IPs correctly? Does it have DHCP correctly set up and running? The error sounds like the channel your WiFi card is listening to does not give IPs via DHCP. This could happen for various reasons: the router is not properly set up, the card is not listening to the proper channel/SSID, the card is banned from the router (because of encryption, MAC filter…), or the device you are using (eth2) is not the one the card is on.

Are you sure eth2 is the correct device? In my case, eth0 is the ethernet device, and eth1 the WiFi card. If your card is not Intel, it may appear under another device name (Google for it, plus read output of dmesg in your machine).

Moreover, can you connect when no encryption is set in your router? Try putting down all security measures in your wireless router. Can you connect like that?

Try using the commands iwlist, ifconfig and iwconfig. They should tell you about the SSIDs that your computer can “see”, and also about the device your OS assigns to the WiFi card.

Hope that helps, and sorry if I’m telling you something you already know.
