wicd unable to get ip address

Ehlyah · 04-21-2010, 08:01 AM

I'm running Karmic and trying to connect to a WPA PSK network with hidden ssid. The network is detected, I filled in the right wpa supplicant (ndiswrapper) and I was able to fill in the passphrase, but like I said, no ip address.

Any help?

After you associate with the AP using wicd, you will probably need to run dhclient or dhcpcd to invoke the dhcp server on the AP and be assigned an IP address.

Thanks for that, but I honestly have no idea how to do that. I googled, but everything went more or less right over my head.

You shouldn't have to do that with wicd. What exactly is happening? It tries to connect and times out? You've double checked you have selected the correct encryption scheme and entered the correct passphrase?

Have you tried to temporarily disable encryption and see if you can connect then?

It authenticates but is unable to obtain an ip address. I've selected WPA 1/2 (I have WPA PSK) and the passphrase is correct.

I can't disable encryption. I haven't got access to the modem/router and the one who does, won't disable.

How strong is the wifi signal?

I often get this problem when I'm trying to connect to public wifi hotspots, but I don't get this problem on my home network.

I assume that it's because the signal is too weak at the public wifi hotspots, but I have no evidence to back that theory up.

I had similar issue as well with wicd on slack 13.37. I gave up fairly easily and resorted to removing wicd and doing all manual through the terminal. One thing i did not try was, there is an option under one of the menus in the gui wicd which will allow you to select between dhcpcd or dhclient. I never tried selecting dhclient, you could try that option. Or give in and do it all through the terminal.

I suggest the OP to try to connect using this command if is available as root or using sudo if that applies.

Code:

# ifup wlan0

However, for the system to be able to use ifup /etc/network/interfaces must also be edited accordingly. Ironically, what helped in my peculiar case, was a defunct thread from a forlorn forum dated 2004! I changed my /etc/network/interfaces to look something like this:

Code:

# WIRELESS Configuration
iface wlan0 inet dhcp
   wpa-driver wext
   wpa-ssid ROUTER-SSID
   wpa-ap-scan 1
   wpa-proto WPA RSN
   wpa-pairwise CCMP
   wpa-group CCMP
   wpa-key-mgmt WPA-PSK
   wpa-psk "passphrase"

Hopefully, this helps you.
