[SOLVED] Wicd unable to get ip

trademark91 · 02-08-2012, 10:18 PM

Hey all, I'm running -current x64 on my lenovo ideapad z575, and after this latest group of updates, my wifi has gone pretty wrong. Wicd detects all the nearby networks, and can connect and authenticate with my home network, but then it just hangs at "Obtaining IP Address" and then the connect fails with "unable to get ip address"

the results of lspci | grep -i wireless are as follows:

Code:

02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

I managed to get online using an old wireless bridge for an xbox, but that's hardly an acceptable solution, especially since it can only connect to WEP and insecure networks (I had to change my router to a WEP encryption just to post this).

checked the logs in /var/log/wicd/wicd.log,

Code:

its just that, over and over again.

any ideas?

Check your conf file if it has your network mask properly. It appears that your box made request to the dhcp server but it cannot/did-not receive an acknowledgement or an offer from it.

trademark91 · 02-09-2012, 12:52 PM

I checked my conf file, it doesn't have anything, actually its still wicd's default config file. This doesnt just happen to my home network, it happens to every wireless network I try to connect to.

vdemuth · 02-09-2012, 01:14 PM

May or may not work. But I had this problem, and changed the dchp requester in wicd to dhclient from auto which cured the problem for me.

trademark91 · 02-09-2012, 01:51 PM

No switching between dhcpcd and dhclient did nothing for me, just a different dhcp client unable to recieve an IP. I tried with a different kernel, still had the same issue. I'm really at a loss here.

vdemuth · 02-09-2012, 02:19 PM

Can you connect from the cli? If so, I would remove all existing wicd conf files from /var/lib/wicd/configurations/ (or at least make copies and then delete them) and see what happens when you retry.

trademark91 · 02-09-2012, 03:06 PM

I can't connect through CLI either. I'm guessing it must be an issue with my wireless card drivers then,seeing as I can detect stuff but can't get an IP from either dhclient or dhcpcd.

edit:
rebuild dhcpcd, no difference.

going to try to build compat-wireless, maybe that will do the trick

/me crosses fingers

nope, that didnt do it either.

checked /var/log/wicd/wicd.log, looks like im getting a lease, but dhcpcd does not want to use it?

any ideas? I'd prefer not to have to resort to ndiswrapper.

I notice from your logs that although wicd is attempting to authenticate, it doesn't show whether it has been successfull.
I would start then with an open wireless network having first deleted all references to current setup in both /var/lib/wicd/configurations, and /etc/wicd,
uninstall wpa_supplicant, delete the /etc/wpa_supplicant.conf file.

If you manage to then connect to an unsecured wireless point, only then set up any security, (remembering of course to re-install wpa_supplicant)

Same thing, it can't get an IP:

vdemuth · 02-10-2012, 11:33 AM

You are still showing some references to wpa (as can be seen from your logs), so there must still be some vestiges of wpa lying around somewhere.

What happens if you provide a static IP?

trademark91 · 02-10-2012, 12:00 PM

I can't, I don't know my netmask, subnet, dns, etc etc, or have any clue how to find that info out without being connected to the network in the first place.

vdemuth · 02-10-2012, 01:04 PM

How have you managed to set up your home network without knowing the details for your isp?

You should be able to get the details you need from your wireless AP/Router, which with any luck will have a standard ethernet port which you can plug into. What wireless adsl router are you using to connect to the internet? Shouldn't be to difficult to get you going wired first of all, then with the details set you up initially with a staic IP to help diagnosing your problem.

malekmustaq · 02-10-2012, 01:15 PM

trademark91,

Okay at least we know the problem and where we are to the solution. Matters of netmask, IP address and DNS inherently belong to the internet provider, else you cannot get into the internet after all you do. You must talk to them and seek their advice on that matter.

Concerning the home-subnet (neighborhood network?) are you on it?, we can help you set it up. Just state the problem and facts and what you did so far.

trademark91 · 02-10-2012, 01:27 PM

Well right now im using a wireless bridge for an xbox, plugged into the ethernet port of my laptop, and had to change my router to WEP encryption just to be able to use this. Not the best solution, and certainly not useable as a permanent one (I need to be able to go to different places i.e. school, work, friends houses) and still be able to connect to the wifi there, I can't demand that they all change their encryption to WEP to work with my temporary solution. I never had to know my netmask, IP, or DNS to connect to the internet before, only the essid and passkey.

vdemuth · 02-10-2012, 01:35 PM

What is the IP of your XBOX and your current wired connection. It stands to reason with that info you will be able to try a static IP. But as I said in one of my earlier posts. You need to start with an unsecured network, and work forwards from there.
