Wireless Disabled in Software after update

[lordluis2000]

Hello Everyone,

I am new on Linux. I used to have Kubuntu 10.04 Yesterday the software asked me for an update and after that. My wireless interface is disable. And every-time I try to check the enable wireless is became uncheck again. And I do have the possibility to go wired.

I have a laptop Gateway LT3201h.

sudo ifconfig wlan0 up
Did not work any of them



Someone can help me?

Re: Wireless Disabled in Software after update

I've never gotten Network Manager to work reliably (and the problem persists into Natty).

I installed Wicd-kde (which is now integrated into System Settings once it is installed) and removed Network Manager (3 modules, including nm-framework).

I've never had problems with Wicd.

Then I use Kvpnc if I need to make VPN connections.

Some day the Kubuntu MOTU will make Wicd the default. It's been 3 versions (at least) that this problem has persisted.

Re: Wireless Disabled in Software after update

I'm running into a problem similar to this. After an upgrade to 11.04 from 10.10 the wireless on the HP netbook will be "unchecked". clicking the "enable wireless" box will cause the computer to instantly lock up, forcing a shutdown and reboot. I've been able to repeat the error three times now.

Fortunately, I'm able to connect wired, so I'm trying to see if there is any updates and/or drivers to fix this.

Re: Wireless Disabled in Software after update

When I upgraded to Natty my wireless went, completely. I can click on the button turning the WIFI on/off and it will give me a notification that it was enabled/disabled every time. I removed KNetworkManager and installed WICD, no difference.
lshw reports that the equipment is unassigned.
A side issue is that the author for IQFIRE-wall, firewall software that I use, cannot load on to Natty because there is a problems with kernel headers installation.
Are the two issues related??
Is it because the WIFI failed at some point after Natty was mostly installed or what??
Is it possible to re-upgrade to Natty using wired connection to solve this problem and is the fix guaranteed

Re: Wireless Disabled in Software after update

I am assuming that you have checked under System > Administration > Hardware/Additional Drivers that there are no proprietory drivers required?

Another thought is that it [b]might[b] be worthwhile installing the linux-backports-modules package which does carry some ethernet fixes.

Re: Wireless Disabled in Software after update

I have been watching this thread with interest because I have a similar experience with wireless bing disabled after upgrade. My lenovo laptop has the broadcom chip bcm 4313 and there does not seem to be a working linux driver with natty narwal. There is actually a long thread in ubuntu forums about the bcm 43xx issues under natty.
Anyway I admit defeat and for the first time i will revert to 1010 to get my wireless working. I'll only consider upgrading once the issue is solved.

Re: Wireless Disabled in Software after update

I did find out that if "lshw -C network" reports back that a network peripheral is "UNCLAIMED", then there is no driver loaded. I had to find the proprietary driver and enable it.
Next, I found that WICD has to be started from "K" -> "Internet" -> WICD and is not found in the System Settings.
