I have an Atheros card, and having downloaded the linux-backports-generic-intrepid thing, my wireless card is no recognized, and I have the option to 'Enable Wireless'.

However nothing shows up under the wireless network part when I left click the network icon - whereas in Hardy there would be 7 or 8 at a time.

I tried to connect to my network by creating a new network, but the bottom green light came on, nothing happen for ages then it asked for my password again (which had been correctly input the first time round).

iwconfig gives this


wlan0 IEEE 802.11bg ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0


Please help!

Also, what do the two green lights stand for when you connect to a network?

Edit to say I have a wireless button, but it doesnt appear to be working in Intrepid - is there anyway I can try turning it on via the terminal - it is meant to be enabled by default though

syslog gives this

Hey man, thanks for trying to help, but the problem is not so much with the detection of the wireless card (I've followed 3 seperate tutorials which have got the system to recognize the card, yours was the third, even though its written for Hardy and I'm running Ibex), but what happens once the card is detected - it doesnt seem to be scanning at all.

iwlist scan returns 'No scan results', and nothing comes up when I left click the network manager icon.

I'm not sure what is going on, and really need some advice.

Same problem here. It's impossible to scan and to connect to a wifi although the wireless card seems to be correctly detected.

I have the same problem...no problem on 8.04, but after installing 8.10 I had wifi with no problem...But after an update to the network manager... I had no more Wifi support (It is recognized, but doesn't scan)....I uninstalled it and re installed the old one (knetwork), no luck.... So what can I do???? I'm stuck using Vista just because of this!!!! Maybe if someone can tell us how to completly uninstall (delete config files, or reconfigure them all) knetwork, network manager, etc..

This latest ubuntu broke lots of things in my laptop... Wifi, sound (Broke with 8.04, I had sound on 7.10), bluetooth.... and the desktop effects...SO SLOW!!!! I had to disable it... It seams that to the new ubuntu a laptop of Dual Core 2 2.5GhHz, 2 GB RAM, and a Nvidia 8700GTM 512MB RAM not shared is an OLD n' SLOW laptop like a truck with 4 flat tires.... I'll have to go back to 7.10, but compiling and installing everything again, installing new libraries to support new software nad breaking and fixing installed software.... I rather ask here and see if somebody can help us solve this issue....

So, can someone help us? Please?
Thanks
Serpentus

P.S.: I know this is NOT the place to ask...but does somebody know how to auto hide the task bar in kde4???..it's driving me CRAZY!!!!! XP :lolflag:

exactly the same problem as the original post, with an Aspire One running Intrepid 8.10. I had the wireless card up and running fine, but after a resume, wlan0 will not activate. I can enable and disable wireless, but cannot select a network.

iwconfig:

lo no wireless extensions.

eth0 no wireless extensions.

pan0 no wireless extensions.

wmaster0 no wireless extensions.

Try search ath5k, modprobe, rmmod. Make sure the router can accept your NEW wireless Mac address. You need to pass '#iwlist eth1 scan", eth1 is the NIC card.
