Ubuntu Networking :: Can't Enable Wireless NIC In BIOS - Keeps Being Reset / Fix It?
Jan 22, 2010
I have an Eee PC 701 4G, and some time ago I disabled its wireless NIC in the BIOS to save energy. Now I've come to need it working again, but I can't re-enable it, because it always goes back to being disabled after I boot the eeebuntu installed on the machine. If I just enable it in the BIOS, reboot and go into the BIOS setup again, it's still enabled, but if I let the OS load it'll get disabled. I'm really at a loss here, how do I find out what's wrong? Could it be Ubuntu that does this?

I used to have Ubuntu 8.04 LTS on my old IBM Thinkpad R40e. I upgraded to 9.04 LTS and seem to have updated to the 10.04 LTS kernel - didn't know about that until now.
Recently I created an Ubuntu 10.10 Persistence Pendrive. I tried to readjust the booting sequence in order to boot from my USB stick Ubuntu 10.10. It somehow failed. - actually I know what to do in a BIOS
My computer still only boots via the harddisk - it does not boot via the Ubuntu-Pendrive nor does it boot if I insert an Ubuntu 10.10 CD. Further I cannot access my BIOS.
Is there any possibility to reset my BIOS manually - I know that some Dell computers have such an option? Any other way to update to Ubuntu 10.10.

My problem, GRUB loader appears when it normally did not and Ubuntu fails to boot. My story, I installed ubuntu on a HP Touchsmart laptop a month ago because I was having troubles with Windows and... well I just wanted to install ubuntu. All goes well until a week ago when my sound was permanently muted through a hardware switch and ubuntu was not detecting it. I tried hitting the button on my laptop but nothing worked. Soo... I tried resetting my BIOS in hopes that it would fix it. I set the bios to its defaults and booted. This is where it got weird. the GRUB loader appeared when it normally did not and upon booting, a black screen with flashing cursor would show up and then... nothing. I changed the bios settings back to what they were and still nothing.
I have removed the silent boot from the GRUB boot line and can see whats going on... a little, the last thing it shows is "Running /scripts/init-bottom ... done." annnd nothing else. When booting in recovery mode it stops after 30 or so seconds on...
Code:
ACPI: Power Button [PWRB]
input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/inp
and just ends on that line. the previous line shows closing the Lid as a button.
I have tried booting into a live USB (as the laptop has no cd drive) and everything works fine.
how the BIOS would be related to GRUB/booting..

When I start my computer sometimes I get an error that my floppy drive isn't working and the boot process is halted. So I disabled the floppy disk seek. But Once in a while (sometimes almost every time I start) the BIOS settings are reset and I have to disable floppy disk seek and reorder boot device list again. I have checked the battery and it's fine. What else can be the problem?

Is there some workaround by changing grub settings other than rewiring the hard disks or changing in bios..
1. my bios is getting reset (low battery)
2. my hard disks are sata and ide, so the ide one is loaded as hd1 by default, cudn't find any way to change that..

Recently I installed ubuntu in my LG P1 express dual laptop, and got it working with the sound, webcam, and LAN. It took me a while, but I have learned a lot. The thing is, I cannot manage to set up wireless networking working. For what I read and discovered, it has to do with an internal RF switch that deactivates the wifi card. On windows, one may switch it on or off with fn+F6. However, that is not working on linux. How to access and change this switch with a command or something?
Nothing on BIOS about wireless. When I do
Code:
sudo cat /var/log/messages | grep -i wireless
I get:
Code:
Feb 17 20:08:34 XXXXX kernel: [27.889915] iwl3945: Detected Intel PRO/Wireless 3945ABG Network Connection
Feb 17 20:08:34 XXXXX kernel: [29.163795] Kill switch must be turned off for wireless networking to work.
On doing: iwconfig, it reads:
lo no wireless extensions.
eth0 no wireless extensions.
So no wlan0 is listed.
However with "sudo lshw -C network" the network is there and the driver is loaded
*-network

I manually reset my router to defaults. Then I changed my router default password, SSID, passphrase, and disabled remote management. I used:
WPA-PSK [TKIP] + WPA2-PSK [AES]
security on the router. When attempting to connect, I use the "WPA & WPA2 Personal" option. This is really strange. I can see the SSID on both my laptops, but I can only connect with one now.

I've been having a network problem that I've been able to temporarily solve by rebooting the router, but even that can be shaky at times, and it can sometimes disturb others' internet activites, so I'd really like to tackle this while I can. I had an old thread about this, but it's ancient history by now, and plus which, I've got a bit more Linux experience and patience than I did before.
The basic problem is that NetworkManager will associate and connect to my home wireless network, but a) it won't let me ping the router or anywhere else ("Destination Host Unreachable"), and b) the connection lasts for maybe a couple minutes at most. If I reset the router, however, 9 times out of 10 it will associate and connect successfully and I can get online, but I have to run a constant ping to the router with a 10-second interval, otherwise it drops the connection, unless I'm doing a lot of other heavy network activity.
ping 192.168.1.1 (the router):
Code:
I've tried wpa_supplicant, but this is what I get (it's apparently unsuccessful...? ESSID/MAC addresses censored where necessary):
Code:
The last prompt line is included because I cancelled it myself; it didn't abort on its own. If left unmonitored, it basically keeps doing this over and over, with no visible network activity at all.
With NetworkManager, I can keep selecting the network's ESSID over and over, and it seems to reconnect, but I still can't ping out anywhere. I'm using a Netgear WN111v1 wireless adapter with ndiswrapper and the Windows drivers. I have no idea what the chipset is, and I doubt that Linux drivers exist for it, even if I knew what it was. The router is using WPA2 security (hence my trying wpa_supplicant)
lsusb:
Code:
ifconfig wlan0 (while connected; IP/MAC addresses censored where needed):
Code:
ifconfig wlan0 (while not connected; IP/MAC addresses censored where needed):
Code:
Code:
I only include this for format checking purposes. The commented out "psk" is the actual text passphrase, while the uncommented one is (presumably) a hex representation of the same key. Is this correct? I've never done this with wpa_supplicant before, I've only used NetworkManager (which is a pain in the @$$ because it requires X to run, and so it disconnects any time I log out/back in ).
Is there any hope of getting my wireless connection permanently working, so that I don't have to reset the router every time I need to reboot or log out/back in?

I just upgraded to natty last night, and everything is working fine except for the network manager. I can enable and configure the wireless card via bash, but the network manager widget will not manage the wireless card.
When I first boot up, the "Enable wireless" check box is greyed out. After I enable the card via the terminal, the "Enable wireless" check box becomes ungreyed, but every time I click it, it instantly unchecks itself. I feel like Currly from the Three Stoogies. Check, uncheck, Check, uncheck.. "Slaps face repeatedly."

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.

First of all, i'll just say this myself. I'm a dumbass and tried to fix somethings that wasn't even a problem from the start and now my 9.10 installation is totally fubar. There, done, now let's move on.
Ok, so I tried to delete a folder after compiling two binaries to the wrong folder and used the
Code:
rm -r
command on what I thought was the folder /home/lars/bin. And to add to the dumbass-ering, I was root while doing this. The computer hangs and leaves me with no other options than doing a hard-reset via power-button.
After rebooting I can't even see the login screen, it just hangs at the Ubuntu symbol.
So I give the recovery mode option in my grub menu a try and it gives me a bunch of lines, all looking good until I get this and the boot just stops with a blinking underscore. code...
Should I just beat myself for a while and then reinstall the OS or what...?
The hardware involved is a Asus EEEpc 1000h.
ps. I'm new to Linux and have so-far managed to get around by following guides and tips, just a heads-up.

I am a day old in ubuntu-world, and I am having internet issues. Yesterday, after i had installed ubuntu alongside windows 7. To begin with it did not detect wireless (not networks but wireless itself), so i figured it was something to do with the adapter and came to these forums where many things were suggested. none worked. So I restarted the system for good measure and lo and behold it detected wireless networks and connected to the internet almost immediately.
Now, after a day, when i have logged in to ubuntu again, there is no wireless detected. The same problem. When I right click on the network icon in the notification area i see that Enable Networking is checked but "Enable Wireless" is darkened. There is no way to check it.
Can anybody please advise as to what to do next. I am using ubuntu 10.04 LTS (Lucid Lynx I believe).My system config is i7, 512MB ram.

My wireless can connect to my router without a problem, but in order to do so (after boot) I must first disable networking in the Notification Area and then re-enable it. I don't mind it too much, but when other people use my computer, it's made painfully obvious to me, that this was never an issue with Windows 7 (as much as I despise MS).

I have recently installed ubuntu on my laptop. However I cannot enable the wireless on it. The card is registered and drivers are installed. From reading previous forums i can guess that its because its "Hard Blocked"" (assumptions). However the switch for it is in the on postion.

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.

I have been having some problems with my wireless connection. I am having to start my computer 2 times in order for my wireless connection to work. The first time I start up, even after I enable wireless it wont connect. If I reboot immediately and enable wireless it will then connect. I would like to be able to fix this problem since it has become really annoying to me to have to boot my computer 2 times every time I turn it on. BTW Network manager shows auto-connect, however it also shows i month ago as to the last time the connections were used.

I am newbie at linux and Ubuntu and I have some problems enabling my wireless. I have spent many hours searching for solutions and couldn't find one for me (maybe don't apply it right - I am newbie). I have HP Pavilion dv6, dual boot Win7 and Ubuntu. At Win7 wireless is ok but at Ubuntu I can't enable my wireless adapter, so my laptop can't recognise any wireless network.

I have an Averatec 3200 laptop with a Intel PRO/Wireless 2200BG card. When I click on Network Connections, it says wireless is disabled. I checked my /var/lib/NetworkManager/NetworkManager.state file, and it said "wireless enabled=false" so I changed it to true.
It just goes back to false on reboot. I also ran rfkill unblock all, but rfkill list still shows that there is a hardware block on. The driver for this wireless card shows that it is installed. I'm not sure what to try next!I just bought this computer used, and freshly installed Ubuntu 10.10 on it, so can't say if it worked in any other distro.

I've been experiencing a problem with Fedora in which when I enable Wireless in Fedora, Wireless networking does not work in windows. HOwever, when disabled, it works correctly. Windows claims it is "not able to find any networks to connect to"
EDIT: It seems that when wireless is disabled manually on fedora before shutdown, there are no problems in windows.

enable WPA encryption on my wireless connection? Wireless networks are detected and listed, so the wireless card is functional in the most basic sense, however, when going to connect to any particular network,I am not given the option of entering a WPA passphrase, only WEP, and as my router is set to use WPA, this is a problem.I am trying to get this going on a fresh Karmic install on a Toshiba A15-S157 notebook.Thus far, I have found this: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/315489 which would seem to relate to my problem.I looked in my logs and saw this entry: Jan 10 16:06:35 cody-laptop firmware.sh[863]: Cannot find firmware file 'agere_sta_fw.bin', and have since found that file, and have downloaded it to my desktop. It seems like this may be the solution, but how to exact it, therein lies my (momentary) problem.
