Ubuntu Networking :: Wifi Has Disappeared In 10.10?
Oct 21, 2010
I did a fresh install of Ubuntu 10.10 this weekend and it worked great. But yesterday night i flipped on my laptop and could not get on to wifi. When i right click there is no Enable wireless option. It is as if Ubuntu doesn't even know that i have wireless. Why would it stop working after a few days?
Either way I am at a complete loss at where to begin fixing this. I would be willing to do a new install but the live CD has the same problem now however it didn't the first time i instaled it:confuse d:. When i boot into my vista partition it works fine so it isn't a hardware problem.

While my wifi still is working just fine (I'm here aren't I), the Network Manager has disappeared from the Notification Area on my panel upon reboot.Have all current patches, so have no clue what to do. Most likely is a bug.

I am having issues with wifi on my Lenovo X220. What has occurred is that the network applet in the notification bar no longer shows me any wireless network options. When I click on the applet, the drop down shows me: Wired network: disconnected (greyed out), VPN connections, Enable networking (checked), Connection information (greyed out), and Edit connections. Missing is Wireless connections. This occurred "out of the blue" in the middle of using the computer (i.e. NOT just after a reboot or new driver installation, etc.)
I have noted that:
1. Wired ethernet works just fine.
2. Wireless (wifi) works when I boot into Windows 7 or into a fresh Ubuntu USB Start up disk (implying that this is a software issue, not hardware).
3. The hardware led for wifi is OFF (whereas the Bluetooth light is on.) In Windows or using a fresh ubuntu from USB, this light turns on normally.
This may be irrelevant, but the issue started yesterday when I noticed that the trackpoint scrolling that I had enabled using gpointing-device-settings was not working. I ran that app and checked the settings, which were normal. I then reset the computer, and found the trackpoint was working just fine, but I had no wifi. A few resets later, the problem was not solved.

The appindicator that showed my wifi status has all of a sudden disappeared. I don't know what happened.
It so it used to be just that problem that I stated above. Now, I can't even install updates anymore from the update manager. When I click install, nothing happens.

I use openSUSE 11.1 since quite a bit and I frequently use YAST (not as root of course). However, since the problems I have to deal with while trying to install WiFi internet access I meet the following problem. I call YAST, get the small authentication screen, I give the right password, which seems to be recognized as such, but I never see YAST appearing. So I can't manage neither my hardware, nor my software.

My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.

I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:

I notived the following problems in /var/log/kern.log

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

I had no problems using my dell mini with ubuntu wireless UNTIL i did a direct connect into my home network to download some updates. Now the wireless connection option has disappeared and only shows a wired connection in "network". Does anyone know how to get it changed back. Terminal no longer shows an eth1 but lists eth0 as the wired connection on ifconfig.

Im using ubuntu 9.04. The network manager (at least thats what i think its called, the thing managing network connections that usually resides on the panel in the upper right corner where you can check available connections, log in to VPN etc) has completely disappeared, i dont know what i have upgraded, i usually just click and download all upgrades..Ive tried to re-add it to the panel but i cant even find it there.

I am using Ubuntu 10.04. I installed the Broadcom STA Wireless driver from System -> Administration ->Hardware Drivers, and it seemed to work fine, but the next time I turned on my laptop, my wireless card wasn't recognized anymore! When I went to System -> Administration -> Hardware Drivers, the driver was gone from the list! Where did it go?Update - Solution:his is hardware issue, not a b43 issue.

My wireless suddenly no longer works either in Ubuntu 10.10 or Windows 7. Upon some investigation, I have found that my eth1 is no longer showing up as it used to.
What can I do to get my wireless back?
Right below is some current specs, while below that is an older set of specs from a while ago.

i have some trouble connecting to the wireless of the dormitery where i live in. so that is what i already did: connecting to the hidden wireless network via nm-applet i typed in my personal user data using "sudo pppoeconf" connecting to the internet using "pon dsl-provider"
so after i did that everything was working out very well and i was able to use the internet without a problem! but after i restarted the computer the nm-applet was gone so i can't connect to the hidden wireless network anymore. if i try to start nm-applet manually the terminal says:
Code:
jonas@jonas-K50AD:~$ nm-applet
An instance of nm-applet is already running.
(nm-applet:1962): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager.
jonas@jonas-K50AD:~$
if i end nm-applet using the system monitor and try to restart it again i get the following output:
Code:
jonas@jonas-K50AD:~$ nm-applet

When the laptop boots I get a very brief message to say "wireless network available, click on icon". But it disappears in a second. I'm not clear whether my WL-140 card is in device wlan0 or wmaster0. Here's what lshw -C network says...

I was struggling frantically this morning for about 5 minutes after I booted up my computer, and wondering why it couldn't connect to the internet. After I figured out that the automatic wired network "Auto eth0" was gone from the network manager, it was easy to manually add it back. But why did it disappear in the first place?

After installing Ubuntu Netbook Remix on my Toshiba NB505, I hoped the wireless would just work right away, but it didn't. After much searching, I found these instructions (scroll down to High Horse's response at #3), which directed me to download the Realtek Driver RTL8192SE. I followed the directions to a T and everything was working wonderfully, until a recent restart that has taken me back to square one. I think the default Ubuntu drivers may be overriding the drivers I installed and putting everything back to default (no wireless), but I'm not sure. Here's the latest output:
Code:

This is a Toshiba Satellite L640 and has a Broadcom BCM4313 controller and Bios version 1.9 and I'm posting by booting my Ubuntu 11.04 cd in "trial" mode which rules out hardware cause for trouble.My 11.04 install is brand new today and wireless was working perfectly immediately after install. Since then, I've shut it down and when I rebooted it I haven't been able to find any wireless connections.
I've installed the updates that were suggested after the install and also activated the two proprietary drivers that th system suggested - this might include the proprietary Broadcom wireless driver, that's the only proprietary driver suggested in the current "trial" mode and I remember there being the graphic driver and one other.I wondered if the wireless was turned off so I tried to turn it on or get it up. I typed ifup wlan0 but it said wlan0 was not configured. In production mode, when I click the wireless icon: it says wireless is enabled and offers me the option of connecting to a hidden network or setting up a new connection, but it can't see any connections even when my phone has seen the connection and automatically signed in. It can't see my home WPA2 connection or my completely open work connection.

The network manager applet has disappeared from my top panel so now I cannot see what local wireless networks are available. I just came from the library and was unable to connect to their wi-fi because the computer wasn't trying to detect it. All I have is a network connections applet that seems fairly useless as it just gives me info on networks I've used in the past and not on any currently available networks.How do I get this Network Manager back and functioning?
