Wireless on Slack 12.2 used to work, now DHCPCD times out.


Hey all,
I know questions of the form "wireless not working on <blank>" abound, but here is another! I can't cut and paste since I don't have a connection on the computer I am having trouble with but I will paraphrase the best I can.

lspci output:
0c:00.0 Network controller: Intel ... PRO/wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

lsmod output (relavent line):
cfg80211 33680 3 iwlagn, iwlcore, mac80211

iwconfig shows wlan0 up and running, and iwlist scanning shows the router. I used to be able to just run dhcpcd wlan0 and connect, but now I get a

"timed out waiting for a valid DHCP server response"

Same deal running /etc/rc.d/rc.inet1.conf (which might be the new way Slack connects to things).

Not sure if it's important, but I have a little indicator light on my laptop that tells me if wireless is running. Before I try dhcpcd, the light is on. After it times out, the light goes out and I have to redo everything (ifconfig wlan0 up etc....) in order to get the light back on.

Anyone have any ideas? I think I'm using the right driver for this, because it USED TO WORK!

Thanks for anything.

Hi thethinker, Have you made any changes to the router? Any recent updates, patches, etc.? If not, my first guess would be the wireless card going/gone bad. Do you have another card you can try?

Good luck. ;-)

changes to the router...not I do not believe so but my g/f could have done something and not told me. Something specific I could look out for?

And this is a laptop so I don't have another card that would work lying around the house at the moment. I've been trying more things (like configuring rc.d/rc.inet1.conf) with no luck. I did get this message:

/etc/rc.d/rc.inet1 wlan0_start
/etc/rc.d/rc.inet1: wlan0 information: 'Any ESSID'
Error for wireless request "Set Nuckname" (8B1C) :
SET failed on device wlan0 ; Operation not supported.

But that probably doesn't help much does it?

Please post the output from the following.

Code:
# ifconfig -a
# iwconfig
# iwlist your_device essid your_router_name key your_encryption_key
# dhcpcd -d your_device
Good luck. ;-)

Ok, sorry for the wait but if it's hard to post output when your computer has no internet access :-P Output like you requested is below, but things are a bit more clear now. It seems to be a router problem; I just installed Slack 12.2 on a super old laptop (AMD K6-2 333 MHz :-)) and it has the EXACT same problem as my badass laptop. So I'm guessing there are some router settings I'm having trouble with - router is Cisco Linksys E2000, works great on windows :-/. And actually, I'm on Ubuntu 11.04 now and it's working well there too! Is there maybe some kind of security difference between Slack and Ubuntu?

ifconfig -a:
Code:

iwconfig: (the other interfaces were also listed as "no wireless extensions" but for whatever reason my iwconfig >> temp command didn't catch those)

Code:

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
wlist wlan0 essid.....this didn't work. said essid was an unknown command to iwlist.

dhcpcd wlan0:
Code:
Broadcasting DHCP_DISCOVER
timed out waiting for a valid DHCP server response

My apologies. The last two commands should have been this.

Code:
# iwconfig your_device essid your_router_name key your_encryption_key
# dhcpcd -d your_device
We were trying to see if you could associate to the AP. I also meant to ask for the output from this.

Code:
# iwlist wlan0 scan
What type of encryption are you using on the router?

Good luck. ;-)
