Ubuntu Networking :: Wireless Hardware Disabled And Cant Re-enable It?
Apr 22, 2011
I was cleaning my laptop and hit the wireless shortcut key on my Dell inspiron and disabled the wirless card. The key will not turn it back on either (I maybe messed with the short cut but dont remember). In the network manager it says "wireless hardware disabled". I am running 11.04 beta with gnome 3 shell. Here is from terminal
dan@dan-Inspiron-1545:~$ sudo lshw -C network
[sudo] password for dan:
PCI (sysfs)

We're on vacation here with free wifi and I brought two laptops. The older of the two laptops running Ubuntu 10.04 and a Broadcom wireless chip suddenly wouldn't work this morning. I checked and it says wireless disabled, however wireless is grayed out when I right click on network manager. I have -no- idea what to do. I've never seen wireless just die like that. I popped open the cover but the wireless card is fine. I re-seated it, booted back up, still no sign of it.
What can I do?

I updated from Ubuntu 9 to 10 some while ago and can no longer connect to the internet via wireless. The computer is a Medion 96290 with a USB wireless card. Running "lsusb" gives code...
This tells me a driver is installed but it may not be the correct one. I copied this driver from the Windows driver file.
Network Manager shows "Wireless Network" greyed out and "wireless is disabled".
WICD shows net8187b as the installed driver and that the hardware is present.
There is a wireless switch on the keyboard which it was not necessary to use in Ubuntu 9 and is inoperative in Ubuntu 10.
I have searched through and applied many suggestions without success and have posted this problem on a couple of forums, again without success.

Last night I already succeeded upgrading to 10.10 (Maverick meerkat), on previous version I never face wireless issue after installed additional package (sudo apt-get install b43-fwcutter). But after upgrading I saw the wireless is disabled and the hardware indicator light off. I used Lenovo notebook.
This is my wireless detail info code...

I've had a host of problems since upgrading to 11.04 Natty Narwhal, so let's deal with these 1 at a time.
I've got a Hewlett-Packard Pavilion G60 laptop. Next to the power button is a handy wireless on/off button. This has always worked well with previous editions (9.04,through 10.10). first press toggles the wireless off, second press toggles it on.
Not so in 11.04. The toggle off works great, first time. But, it will not toggle back on. Not after any number of tries, not after restarting, not after booting into other OS's (9.10 and Vista) re-enabling it there and then booting back into Narwhal. to further complicate the issue, this feature bypass the network manager, so toggling the wireless off by the switch leaves me showing no wireless adapter in the network manager. I also restarted, switched from Unity to a Gnome session, but the issue still persists.
As my only network options are wireless, this has become a substantial inconvenience.
----
EDIT: so the network util is actually saying "wireless disabled by hardware switch". Also noticed it I enable it in 9.10, reboot to 11.04 (where I inevitably fail to re-enable it), then reboot into 9.10, it will initially be disabled. The key difference is in 9.10 I have the ability to enable wifi using the hardware button. It seems that 11.04 is remembering that wireless is disabled between boots. Is there a place it might be storing this value? If so, I may be able simply to set the value as enabled, since toggling that silly button isn't working.
-----
EDIT 2:
found this thread:"Wireless disabled by hardware switch" bug? - Natty
seems to be a similar issue. I'll be following how that one develops, too.

I have been using ubuntu 10.10 (running on a Dell Inspiron N4010) for a couple months and love it but the wireless just recently stopped working and I can't figure out how to re-enable it. I've searched endlessly the FAQ's, forums, etc but nothing seems to work.

I have recently installed 10.4 (wubi installation), and am having strange problems with my networking.
It was working fine, wireless enabled, connecting to my network fine. Then for what seems like no reason, it decided to disable the wirless on boot, and I cannot re-enable it, the option to enable it (by right clicking the nm applet) is greyed out.
I have had this problem twice now, the first time it happened, my ubuntu installation was really new, so I just reinstalled, no harm done. The second time I did something that seemed to fix it (for a while at least), but now that is not working.

I am using openSUSE since last 4 years ,which is installed on my External Transcend 320 Gig External Hard-disk. Now I don't know why but my network is not working, i.e. when I click on "Network Manager", it reads, "Network Manager disabled". So is there any way to overcome from this problem? I also tried to restart the network service but, it did not worked.

I cannot seem to enable my wireless connection in 9.10. I know that the connection WAS WORKING maybe a month or so ago. However, 99% of the time I am wired.I am using a BCM4312 It shows up in lspci The drivers are loaded (wl, lib80211 and lib80211_crypt_tkip) If I look at System->Administration->Hardware Drivers the Broadcom STA driver is active. dmesg says that the interface is eth1 but then moves it to eth2 If I click on the network icon in the panel I have options for connecting to eth0 (wired lan which works fine) but under "Wireless Networks" it says "Wireless is disabled" in gray.

Here is what I got:

My wireless was working fine for about a year using 9.10 until I installed an update about May 28 2010. After that my HP laptop did not recognize any wireless routers including my Netgear. In early June I upgraded to 10.04. My HP laptop has: product: AR5001 Wireless Network Adapter vendor: Atheros Communications Inc. Dose the following apply when looking for the source of my disabled wireless found at: [URL]
Setting wireless regulatory domain via module option no longer supported. Ubuntu 10.04 LTS enables the CRDA wireless regulatory framework for controlling which wireless channels are usable and visible in a particular location. If you previously had to use the module option similar to that below in /etc/modprobe.d/options.conf to allow access to certain channels in your locality then you may find that wireless will not function at all: options cfg80211 ieee80211_regdom=EU You should remove this kernel module option on upgrade from releases earlier than Ubuntu 9.04 and use the iw*reg command instead. (This change was made in Ubuntu 9.04.) Here are the results for the Code sudo lshw -C network

I realize this seems like a repeat question (and it probably is). I have been searching for a solution to my issue on the forums/web for a few hours to no avail. I have a Compaq f700 with Vista. I am sick of Vista. I installed Ubuntu today. Looking forward to using it more. However I am having problems with the internet.
My wireless internet is on the on setting, however, the light will not switch from orange to green (if I load Vista instead, the light changes). Broadcom BCM4311 802.11b/g WLAN [14e4:4311], It says my wireless is disabled. I can not figure out how to enable it.

I'm running Ubuntu 11.04 latest updates on a HP G50 laptop. It was working fine but would never auto connect to wireless. I would have to select the wireless from the top menu and connect to a network. However I disabled it once and tried to re-enable but ran into a problem. The Enable Wireless was grey and would not allow me to enable.
Have searched google and tried lots of solutions and none worked. I even reinstalled and still have the problem.

So, after installing Lucid wireless doesn't work for me. When I click on the network icon on the status bar, it shows "wireless is disabled".
With that message, I press the wifi button on my HP laptop and it turns off my blue-tooth, without changing the status of my wifi.
I found this rfkill command in another thread:
Before doing anything, after bootup:
Code:
$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

I have an HP mini laptop (Intel Atom, N270, 1.60GhZ, 1Gb RAM, Win XP ver 2002 SP3) that I upgraded to Ubuntu 10.04 netbook version last nite.I can dual boot, and so far everything under Ubuntu works great - except for the wireless interface. Rebooting back to WinXP, it works fine. The 'sudo lshw -C network' command shows "disabled". Ubuntu sees it, its just disabled. The help file says to make sure its on. It is - there is no physical switch..I am VERY new to this, with no programming experience to speak of.

In simple, I have tried everything I can find on this issue, but I am still unable to get it working on my HP DV4 laptop. My laptop has a Intel 5100 wireless card, and it always says that wireless is disabled. Ive tried booting with the wireless switch off, with it on, ive reinstalled the driver and did everything in a post I found here (cant find a link) that basicly had me reinstall the driver from intels site, then reload the network manager, to no prevail. Im running ubuntu 10.4.1 (just installed), and this is really a big issue 4 me.

after finally getting this machine tot run with ubuntu i am now on an ethernet connection because all of a sudden, my wireless says its disabled. When iwconfig is entered, it shows my wlan 0 but says power management : off. It is so frustrating because I feel like there should just be a button that says to switch it on haha. Please help, my wifi was working, and after a boot it is no longer.

I'm new to ubuntu. Recently installed 10.10 on my dell inspiron 1546. The bluetooth does not seem to be working. In the bluetooth preferences window it says "bluetooth is disabled" and pressing the "turn on bluetooth" does nothing.
lsusb shows nothing.
hciconfig -a shows nothing.
Bluetooth is enabled and working in windows 7 with up to date drivers.

i hate to start a new thread that is already discussed in many places. But after hours and hours of digging, i am thinking there might be a 5 minute solution. But only if i know that. I own a lenovo ideapad y450. my networking controllers are...

Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection
Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
The problem is i cannot access wifi. The network manager says the wireless is disabled by hardware switch.
My hardware switch for wireless (on the laptop) is infact ON.
[Code]...
During natty installation (it was a fresh one) i had ticked for third party installations but had no internet running at that time. now the additional drivers under hardware in system settings shows nothing. just blank. NO MATTER WHAT I DID I HAVE COME TO THE FIRST STEP AGAIN. MY WIRELESS IS DISABLED BY HARDWARE SWITCH. where is this switch & how do i switch it on (if thatz so easy.) but all the solutions given in other thread were specific to some system or condition and mine somehow did not match.

Just installed ubuntu 11.04. It told me a driver was missing and installed the Broadcom STA driver. I believe it went on line after that, but I restarted and its not going back online.
Also according to 'rfkill list all' my wifi seems to be hard blocked.
EDIT: also iwconfig outputs this:
Code:
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bg ESSID:off/any

Just upgraded to the newest version of Ubuntu(unity), and my wireless isn't working. I have the 14e4:4315 Wireless Card so I followed this posts [URL].... And still have no wifi, when I click the icon in the menu bar it says under "Wireless Networks": "wireless is disabled by hardware switch", which ins't true because on my Vostro 1520, there is only one switch and it is in the on position. I've tried 3 versions of ubuntu and none of them work with wifi getting tired of it.
