Can you please post the output of
Code:
lsmod
and
Code:
lsusb
? You said your Wifi adapter is USB, right?
What make and model is it?

Cheers,
Tink

Have a look here, seems to have been a similar (though not identical since it affected wired, too) problem, but it may help: https://bbs.archlinux.org/viewtopic.php?pid=694576

Hi Group, I must say, me too! Experiencing the same problem with limited penguin experience. Half the time I boot my BT5 live USB I don't know if the wifi will be online. So far every time I have resolved it, it's been a different solution. Progressively getting more complex I think LOL. My BillyBox never gave me this much &$#@!. Ok, done venting. Kindly help, pls.

Running BT5 Live on USB stick in laptop with atheros wifi card. Currently experiencing inoperable wifi. The wifi device is definitely supported and has operated perfectly and recently. I am too now experiencing the wifi wicd dbus connection error. But I only seem get the error message the first attempt to connect. At this point the wicd manager does seem to actually scan the air for a second before 'No wireless networks found' (sometimes not) I find the wifi wireless LAN both soft and hard blocked. unblock all does not release this time. I have rebooted. I have verified the iso hash and reinstalled the USB iso. This same iso has worked perfectly in the past. I have hard booted with power cycle (powered down, remove bat, a/c & all peripherals. Held the power button for 15 secs to dischard anything left inside, then restarted)

Kindly help? I've been able to restore from this condition before, each time being a different solution, but this time... I can't understand how the problem persists after hard boot from USB live. btw, I never configured it with any file storage allocation, so everything would be cleared every time I shut down (by preference).

Wired does work fine. I'm currently using WEP btw.

Thank you.

For now I'd work through the suggestions both here and at the link I posted (https://bbs.archlinux.org/viewtopic.php?pid=694576) and see how you get on. Report back once you've tried everything.

Hi, thanx but im about the end of my rope. Been reading for days with trouble understanding half what I read and inevitably run into command not known or not installed. I figured everyone's using the same BT5? Seems to be a different solution to every other similar trouble shooting post and I don't know how to trouble shoot my specif conditions. I know it used to work and I can't imagine what's changed in the hardware of software.

OK - start by trying this: http://www.linuxquestions.org/questi...7/#post4584552 (previous page here). You'll need to use sudo to start wpa_supplicant, so prefix the command with sudo and enter your password when asked. Watch the output and post it back here. We can at least check whether or not you are getting a suitably authenticated connection to your router that way. Don't panic at this stage if you get a connection, but can't reach any websites. Test the connection by pinging:

Code:
ping 8.8.8.8
If you get times then we can move on. If you get errors such as "Destination is unreachable" or anything to indicate that the connection is down, post those error messages, too.

Hi again, Joy! Thank you so much, Roken, for taking the time to start troubleshooting with me. While I've been pulling my hair out all afternoon, I just now happened upon some joy. I was worried I fouled my wifi card. I stumbled upon a solution in a post on another forum and wish to post it here in the hopes it may help others fix, troubleshoot and understand.

pkadetiloye reports in relation to the error message SIOCSIFFLAGS: operation not permitted unknown code 132
at via http://ubuntuforums.org/showthread.php?t=1465738

This solution that resolved my issue (also an HP G60 box) as simple as that and I quote:

"well, I eventually got the wireless working when I read a post on a forum and I'm going to post it here as the authoritative solution to the problem. (Sorry, I can't figure the original URL, but you can always paste it here for due credit!).

$sudo rmmod ath5k (you may have to replace with your driver module e.g ath9k)
$sudo rfkill unblock all
$sudo modprobe ath5k (you may have to replace with your driver module e.g ath9k)"

Academic now, but for future reference the correct syntax would be:

Code:
sudo wpa_supplicant -D wext -iwlan0 -c/path/to/config

Ah see that. That explains why I been seeing so much 'unknown commands' I go back to the DEC10, you'd think Ida picked up a little Unix somewhere, but I just never went there. I started reading an old & early linux tutorial at northernjourney.com and picked up the dummies book on penguin ;]

Thanx again!
