Ubuntu Networking :: Reboot "looses" Wireless Device?
Sep 12, 2010
I installed Ubuntu 10.04 for the first time and had a few issues to put my laptop's wireless device to work (see thread [URL]I am now able to use the wireless connectivity but I still have a problem. Every time I reboot Ubuntu, the system does not seem to recognize that a wireless device is present. To overcome this problem I remove the driver and once this is done I activate the driver.The system then finds the wireless device, enables it and connects to the default wireless connection.

The ethernet configuration files are under
"/etc/sysconfig/network-scripts" such as "ifcfg-eth0:1" etc.
The file looks as follow:
Code:
DEVICE="eth0:1"
BOOTPROTO="static"
ONBOOT=no
IPADDR="172.23.17.10"
NETMASK="255.255.255.0"
ALIAS="yes"
I've set the ONBOOT=no. This means this device should not be activated at boot-time. But as I reboot the machine, this device is activated again. This means the option ONBOOT doesn't work. Seems this is a bug of RedHat LINUX?

I've had my wireless networking (on an Acer Aspire laptop) working perfectly well for at least six months.Now, quite suddenly, after a reboot I get the message from wicd, "No wireless networks found". I probably was running a week or so before that without needing a reboot. Windows wireless is fine (I'm using it to send this post).In addition, my sound stopped working and I see a fleeting message to the effect that the sound system is reverting from analog to digital.I'm running Kubuntu 9.10. My guess is that something in a recent round of updates knocked me out of the box. How can I proceed to set things aright?

I've been searching forums like for 2 days, but couldn't find any similar problem.
First of all im running Ubuntu 10.04 desktop version on my netbook Acer aspire one (AOD150)
Every time i turn off my netbook and after turn it on, in "Hardware drivers" it says that driver for wifi is not in use, also button for switching on/off wifi is not working.
So everytime i start up i have to go into "Hardware drivers", remove driver for wifi, and then activate it again. And everything is working gr8 after. Its just too annoying to do it everytime.

i installed linux on this laptop around 2 years ago (hp g6000 laptop) with internal wireless card and was unable to get the internal wireless card to work under ubuntu. so i purchased a linux supported usb wifi stick, which worked perfectly (connected automatically on boot) each time. however, i moved house recently and lost this usb wifi stick. i am currently using a ethernet connection to my hub and have updated ubuntu to the current version. all software is also up to date. since i lost my old wifi stick, i have used this connection, however, yesterday when i was on videos, all of a sudden (without me having done anything {intentionally anyway}) i see the wireless connection graphic at the top right of the screen! both green dots lit and the connection was live! so i disconnected the ethernet and used the wifi all night without a hitch.
i was extremely happy with what had happened and could not work out why it had decided to work (having not been aware to doing anything, except sit and watch a videos video). so i shut down, go to bed, go to work the next day and come home looking forward to browsing the web from my sofa, and guess what, no internet connection once i logged in! i just think 'if it worked last night, it can work now'. i have ndiswrapper and i have the .inf driver file for the internal card installed in ndiswrapper. i have opened that tonight and it looks okay - except it says 'hardware present: no'. i do not understand what has happened at all. (also there is a wifi 'on off' switch on the front of the laptop, with an orange led but neither position makes any difference to the card working or not and it hasnt changed positions since i moved house (to the best of my knowledge anyway).

I recently installed Ubuntu 10.04.1 LTS and have it set to dual-boot with windows 7 on my gateway tablet PC. Since installing, sometimes when I suspend or reboot, my wireless does not work. To be more clear - it is working fine, then I either suspend/reboot, then I come back and no wireless networks show up at all. I can still connect with ethernet cable though. I can solve it by rebooting multiple times (usually around 1-5 times) and then it (magically) seems to work again. I have also tried switching from network-manager to wicd, but the problem persists. With both network-manager and wicd, I've tried simulating a reboot for the wireless by using the command 'sudo modprobe -r iwl3945 && sudo modprobe iwl3945' (network-manager) and 'sudo /etc/init.d/wicd restart' (wicd), but these do not seem to work.

I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.
I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.

do not post such long blocks of messages directly on the forums. Attach the output as .txt or use a pasetebin.

I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:

I'm running Linux 11.04 and my wireless network was working just fine until today. I cannot connect to WiFi - it acts as if the device wasn't there. The hardware switch led isn't working. No matter how much clicking on it, it won't work.
iwconfig:

School with linux running on students' laptops, connecting via wlan to a Debian NFS and LDAP server. Every student logs on his/her profile residing on the NFS server.The clients are set up with autofs. Earlier, I had set up the wireless network in /etc/network/interfaces, but this time I decided to configure network manager so as to bring up both wireless and wired network before logon. This setup has been working on for the last fire or five years with only minor changes. Also worked with Karmic Koala, but still with the interfaces file instead of networkmanager. The Vostro is also new here, we've previously used mostly Dell Latitude D505s.
So here is what works:
1: Clients can log on to LDAP and NFS servers both wired and wirelessly. Everything is smooth.
2: While on LAN, shutdown and restart works flawlessly (and quick as a breeze, I'm really impressed by startup/restart/shutdown times, under 25 secs!).
3: Shutdown and restart also works wirelessly when doing it either from a local account or from the GDM chooser.
What doesn't work, however, is shutting down or restarting directly from a networked account connected while only being connected over the wireless network. This is what's being displayed on the terminal after it has tried tho shut down for a while:
Code:
The system is going down for halt NOW!
acpid: exiting
init: cron main process (1011) killed by TERM signal.
init: tty1 main process (1365) killed by TERM signal.
[code]...
If I try ctrl-alt-del at this stage, it says:
"init: rc main process (3030) killed by TERM signal"
"Checking for running unattended-upgrades: "
And then it will hang again, until I hold the powerbutton for some seconds. The unattended-upgrades part is what seems to be the culprit. I suspect it is about the wireless network not being connected any longer or something like that, but I'm not sure about how to go about debugging shutdown scripts here. I'd be grateful for pointers. I will try and see how it goes with the old interfaces file setup, but I'd rather make nm work.

I had been manually starting my wireless network with "sudo iwconfig wlan0 essid "my wireless router id". The network would start and work flawlessly for weeks at a time. I can't ask my wife to find the essid in the terminal and then start wireless manually when I'm not here. She hates and fears the terminal. So I downloaded gnome network manager for a point and click interface on gnome panel.The network would start fine but shut down after anywhere from one to six hours. It would then refuse to restart manually or otherwise. I completely uninstalled network manager and tried wicd instead. The same basic problem is happening. The network will restart if I reboot the computer. My system:
Desktop computer acting as proxy server for the internet. Internet connection is by a dial up modem. This computer uses a wireless pci card connected to a dedicated hub. This is for file sharing via nfs. The OS is ubuntu 9.10. My wife's computer sharing the internet using a proxy to my computer. File sharing via nfs and a wireless card. Also running ubuntu 9.10. This same basic system worked flawlessly under Ubuntu Hardy.My desktop was updated recently with new hardware which created the need to move to Ubuntu Karmic. Some hardware was too new for hardy to deal with.

I have freshly installed ubuntu 9.10 and moreover i am completely a newbie to Linux. The problem now i am facing is, i am not able to configure my wireless router. I tried finding drivers for it in System->administration->hardware drivers. But it showed me none. Then i checked out one of the threads in this forum and came across the 'lspci -nn' cmd. This gave me the info abt my wireless network controller and it was : 'Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)'.

I've tried to install Linux systems have been failures. Trying to make this work, trying to get on the right wagon, and it's frustrating as all get-out.
Installed netbook remix onto a HP Mini 1000 (1116NR?) and everything seems to be working alright, except no wireless networking. I tried a couple of things and now it shows "device not ready" instead of "disabled", so I figure I'm getting somewhere.
The device is:
Broadcom Corporation BCM4312 802.11b/g (rev 01)
I want in. This is my 3rd try over the years of running Linux and I always hit snags like this that I can't fix because I've never gotten to play with it enough to learn what I'm doing and generally don't have a 2nd computer like I do right now.

It's been ages since I've been on here I've been messing around with BackTrack. I've come back to Ubuntu but seem to be having some problems getting my wireless network thingy working. Here are the specs of my system. Any advice on fixing this would be very very apprciated.
02:06.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller (rev 01)
02:08.0 Ethernet controller: Intel Corporation 82562ET/EZ/GT/GZ - PRO/100 VE (LOM) Ethernet Controller Mobile (rev 01)
10:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
On another note I'm trying to run debain I've got no startx on there or anything like that it's feeling very basic atm. I want to keep startx outta there but I can't connect to the Internet and run apt-get install to grab handy things.
I'm hoping whatever I am gonna do to solve this on Ubuntu will let me connect up to my wireless network with the internal network thingy. However if it doesn't I'm guessin I can just connect up physically to the router. Any tips on doing this from the command line?

Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.

I just recently installed ubuntu, my first experience with linux. I don't know if it isn't recognizing my wireless card or if it is another issue, but I am unable to view any wireless networks/connect to any. When I click on the network icon it says "wireless" with Device Not Ready underneath.

I think that's all that would be needed to help diagnose the issue. I'm kinda new to linux, and this is primarily a music machine.

I've been using Ubuntu for a while, but I have never tried to set up a wireless device with it. I have no idea where to even begin. I've done a search of the forums but wasn't able to glean much from it.

I am running UNR on an Asus T91MT and everything was working great until an update yesterday, my OS froze while updating and I had to do a hard reboot. Since, I have not been able to get wireless, and lshw does not even recognize the presence of a wireless device on the system.

I recently bought a new nettop and installed Ubuntu 10.10 Desktop. Unfortunately the on-board wlan is kind of crap so I bought a USB Wireless stick and since that stick has a pretty recent chipset ndis was needed to get the USB stick to work as wlan1.
The issue is I want to disable the on-board wlan (wlan0). The BIOS does not offer that option so it needs to be done in the OS I guess. My question is what is the best way of doing so? I've read something about blacklisting or editing 10-wlan.rules but I am unsure what the best place is and what to put there.
This the output of ifconfig:

11.04 64 bit I just picked up a new high-gain usb wireless adapter that I would like to use for a while in place of the built in wireless adapter in my desktop. It is detected and works just fine. My question is this: Is there any way I can disable just the built in adapter and leave the new one active (or visa versa?) I don't want to remove the built-in one as there will be occasions that I will want to use both.

I'm new to ubuntu and using 9.10. I have installed a dlink wua 2340 wireless adaptor and it is working properly. But after waking up computer by standby mode, wireless connection breaks and the wireless device is not mounted. Therefore I always have to shut down the computer and restart again to establish wireless connection.

I just installed Ubuntu 10.04 and I can't seem to get the wireless connection to function. Ubuntu either says that the card is turned off or if I toggle the wireless switch on my keyboard it then says 'device not ready.' I'm using a Dell Wireless 1397 WLAN Mini-Card, and it works fine when I boot in Windows 7.

I have a Linksys Wireless-G USB Network Adapter, 2.4 GHz, 802.11g. It hooks up through USB plug, and when I originally plugged it in I got the message that ubuntu didn't support the drivers, but haven't seen it since. I'm hooked up to a LAN cable right now, and can't seem to figure out how to hook up through wireless with this device. Or I just don't know how. When I click on the network connections button on the top right corner (the two computers). I can see my Wired Internet, but no wireless. When I type lsusb in a terminal I get : (sorry I don't know how to do code blocks) So it is recognizing that it's there, but maybe I just don't know how to use it. Also, I'm running Ubuntu Release 10.04 (lucid).
