The Usual... a Broadcom 4311 issue
 
OK. I'm a newb at anything Linux. I admit it. Nearly helpless I am.

I installed Ubuntu 10.10 on an external drive. Had issues for a bit, but when I connected via cat5 cable, *poof* wireless was working - well, even! Then got my new hard drive installed & loaded up the same distro on it.

No wireless, no matter what. I've been through tons of sites & nothing yet has managed to connect me to my home network.

The chipset is 4311 as 'eth1'.

Love Ubuntu, but I've GOT to have wireless or this thing is just a boat anchor.

Any ideas?

If you are seeing an eth1, can we assume then that the device is being detected properly? Do you see a wireless device when running the command "iwconfig"?

Assuming the device is being detected properly, what exactly is the issue? Are you unable to scan for networks? Can you see them, but not connect? Is it an encryption issue, or is the AP running open?

The result of iwconfig is:
"lo no wireless extensions
eth0 no wireless extensions
eth1 IEEE 802.11 Access Point: Not Associated
Link Quality:5 Signal Level:0 Noise Level:0
Rx invalid nwid:0 invalid crypt:0 invalid misc:0
"

The home network is detected, but listed as "hidden". Not sure of the meaning there, but the SSID is tranmitted. Ubuntu will not connect. I have tried both changing & disabling my security with no results.

I ran "sudo iwlist scan" in Terminal and got the following result, (if it helps):

BULL@******:~$ sudo iwlist scan
lo Interface doesn't support scanning.

eth0 Interface doesn't support scanning.

eth1 Failed to read scan data : Invalid argument

You might have a look in your log files and see if the sta driver is complaining about anything. By the way, did you get the driver from the Ubuntu repository or did you compile it yourself?

Being so new to Linux, I have not attempted to compile anything - relying on what is available.

OK, then have a look in your log files (/var/log/syslog, /var/log/messages, the output of dmesg) and see if sta is complaining.

issue solved.

more digging showed a rfkill issue.

Thanks!
