Ubuntu Networking :: Wireless Disappeared From Applet X220 + Realtek Wifi?
Jul 29, 2011
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.

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

the nm-applet seems to have disappeared from the top panel, whenever I run the command it gives me the output:
Code:
** Message: applet now removed from the notification area
** (nm-applet:8695): DEBUG: old state indicates that this was not a disconnect 0
** (nm-applet:8695): DEBUG: old state indicates that this was not a disconnect 0
** (nm-applet:8695): DEBUG: old state indicates that this was not a disconnect 0
** Message: applet now embedded in the notification area
I have tried the --sm-disable parameter but that doesn't help ether

I just installed SUSE 11.4. In short - my adapter is working, authenticated on the selected AP, I can ping the AP, but I have no access to the outside world. Here's the command line output:

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?

Yesterday while trying (unsuccessfully) to get a new Bluetooth dongle set up I lost the network manager applet. When I rebooted, after giving up on Bluetooth in Ubuntu, I had no way of connecting to my wireless network. In command line (iwconfig & iwlist scan) I was able to see the wireless router. So the wireless card is working correctly. How do I reinstall the network manager applet? Oh even when use a wired connection to the router there is no connection.

I have assigned ip address to laptop by editing /etc/network.interfaces. From next reboot the Network Manager Applet which was present on right hand upper corner, disappeared. I wonder why? This has happened with 9.04, 9.10 and now in 10.04. Another question is, are Network Manager settings (ip) and /etc/network/interfaces do correspond to same thing or not? As I have narrated above, since network manager applet is no more visible how to see the physical network cable connectivity status (as we do in windows xp)? (is there any other app of such kind or what?)

I have downloaded the driver installed it, and it works fine. But i can't get to turn it off. I do have the ability to unload the driver's kernel modules and the sysyem does not see my card after that. That's ok, but i'm thinking it still uses my battery power. The wifi led is always on no matter what i do. The fn+<wifi key> doesn't to anything.

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.

Now my question: is there any way to give nm-applet the information with some start option to start with wifi swiched on? Inside the connection Options i already switched on "connect automatically" and "all users can use this connection" also i found the option inside /etc/NetworkManager/nm-system-setings.conf

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

The auto connect feature of NetworkManager Applet (version 0.7.997) isn't working on my system. If the WiFi connection dies, Network Manager doesn't detect that the connection has been lost and try to reestablish the connection. I have to manually click on the WiFi hotspot to reestablish the connection. This appears to be the case both while the computer is running and when I first boot it up (i.e. when booting, if the first attempt at establishing a WiFi connection doesn't succeed, Network Manager doesn't retry or try another hotspot).Is this "normal" behavior for Network Manager? If not, does anyone know a fix? Here's some more info about my system:

WiFi Chip: Broadcomm BCM4238
Kernel Version: 2.6.31.12-174.2.22.fc12.x86_64

Im not able to establish a Wireless Internet connection in Ubuntu 10.04.
Ive tried these steps:
1. Wireless Internet did not show via the Network-icon. Only the 2 LAN-gates where shown
2. I installed the Windows Driver (net8185.inf) via ndisgtk package
3. After restarting the computer, 2 LAN-gates and 1 WLAN where listed via the Network-icon
4. Normally WLAN should automatically start scanning for available networks, but that didnt happen
5. When I tried to connect to my own network, the computer tries to connect for 1 minute and than stops because no connection could be established
6. A wired Internet-connection does not give any problems
Details:
- I first had Ubuntu 9.10 but I wasnt able to make a WLAN connection either. I followed the same steps. After that I upgraded to 10.04
- iwconfig in Terminal gives an IP-address which consists of 12 identical characters.
- lspci in Terminal shows these data:
01:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
[Code]....
My questions:
- How to create an Internet connection via my WLAN-card?
- How to install the option to search for available networks automatically?

I recently purchased two MSI Windtop AE2220's. One for my home which uses a router with WPA2 protection and one for my office where I use WEP encryption.
The Realtek internal wireless card will not connect to a WEP router if you are running Ubuntu Lucid Lynx 10.04. I have exhausted all suggestions on this site and all drivers found at Realtek's site.
I have been using Ubuntu since Hardy Heron, but sadly, painfully, I have had to install Windows 7 on my office machine until I find a wireless card compatible with the MSI Windtop AE2220, Lucid and WEP.

I am using ubuntu 10.04lts on my compaq615 laptop, which has a realtek wireless card, with which I had a few issues to get it to work.
Here is what I had to do:
When I do this, it works beautifully, after setting my router to open I may add.
So, as I said it is probably the fastest wireless I have ever experienced, but my problem is this, everytime I switch my laptop on I have to re-install, starting at:

I have a Toshiba Satellite L655-S5061 laptop and dual-boot Windows 7 and Kubuntu Lucid Lynx. Windows detects and connects to the wireless network just fine, but in Kubuntu it will detect the network but can't connect to it. Sometimes Network Manager will say it's connected, but Konqueror can't load any websites. Plugging in an ethernet cable doesn't give me access to the internet, either.

I was able to successfully install the drivers on the generic kernel, but I seem to be having a problem getting it done on the real time kernel I downloaded via the Ubuntu Software Center. Here's what shows up when I type in 'make' at the command line:

The Realtek RTL8111 wireless does not work in Mint 10 or Ubuntu 10.10. Works perfectly in Mint 9 and Ubuntu 10.04. No proprietary driver necessary. Has anyone managed to get it working in Ubuntu 10.10? : You can click the one you want to connect to and enter your security key. I just use WEP because it's easy. I enter the key and the system just tries to connect until it times out. You can repeat this process indefinitely. Wired works fine but after any available updates are installed, still no wireless capability.

Just installed ubuntu on my computer, but when I try to connect to my wireless I type in my password and it doesn't connect.
It says its WPA/WPA2 and won't let me change that (I am not sure what mine actually is)
Im using a virgin media 'superhub' to connect but have changed the default wireless password.

I recently upgraded to Ubuntu 11.04 (natty-64 bit) and my wireless PCI card is not being recognised by default. Previously, when I upgraded to 10.10 I had to go to the Realtek website, download the driver for RTL8185 and install it (following instructions in the readme file) to get my wireless card recognised and working properly. This time around, that approach doesn't seem to work. When I try to install it using "make" I get the following error:
make: *** /lib/modules/2.6.38-8-generic-pae/build: No such file or directory. Stop.
make: *** [all] Error 2

I'm having trouble with my Samsung Netbook N220 and its Realtek 8192 wireless card and could use some help with diagnostics. I would like to use the netbook as a server and after a day or so the system stops responding. What I'd like to know:
- What do the "========>ieee80211_parse_info_param(): athros AP is exist" spam messages actually say? Does anyone else have this and stability problems?
- Why is the realtek driver package not working?
I'm running Ubuntu Netbook 10.04/Kernel 2.6.32-24-generic. Initially the card was unable to connect, so I installed the Realtek driver rtl8192se_linux_2.6.0017.0507.2010 which adds a kernel module r8192se_pci.ko. At first my system was hanging during bootup. I then restored /lib/modules/2.6.32-24-generic and now the card is connecting but the system is unstable. The 2.6.32-23-generic kernel, modules listed below, still has modules as installed by the realtek driver and is not working. Below the drivers supplied by ubuntu
./2.6.32-24-generic/kernel/ubuntu/rtl8192se/r8192se_pci.ko
./2.6.32-24-generic/kernel/drivers/staging/rtl8192su
./2.6.32-24-generic/kernel/drivers/staging/rtl8192su/r8192s_usb.ko
