Ubuntu Networking :: Wireless Support Disappeared After Updates

May 9, 2011

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.

Fedora Networking :: Lost WPA Support After Updates

Mar 5, 2011

Running FC14 64 bit with KDE. I have an atheros wireless card that was working fine for months. Just recently I downloaded and installed some updates I got automatically. After a reboot, I have suddenly lost my wireless connection. I am still able to connect to unsecured networks but my network uses WPA and the status of the connection always freezes on "Awaiting Authentication". When connecting, it pops up the secrets windows asking for the wpa key even though its already entered. I've reset my home router several times to test various configurations with no encryption and with WPA. My key is correct but it will not connect. I've researched this issue and found others to have the same problem though their fixes have not worked for me.

I've gone through a few things. Wireless radio button on, networking and wireless enabled in fedora. Card still shown in lspci and with iwconfig. Funny enough, there was no wireless card listed in Network Manager. So I added the connection again and set it to be controlled by network manager and start on boot. No difference.

I'm wondering exactly what was updated that caused this. I didn't pay attention to what updates they were. This update occurred 3/5/2011. I've tried booting to the two previous backup kernels, but that doesnt help either. Also ran dmesg | grep wlan0 to find that the device was not active or ready but I could still connect to unsecured networks. So I'm stumped and would really rather not reinstall. Besides, when I get the updates again, it will probably do the same thing. Is this a bug? I would post more information but I am not with my box at the moment.

Ubuntu Networking :: Wireless Connection Disappeared?

Feb 19, 2010

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.

Ubuntu Networking :: No Wireless - Eth1 Has Disappeared?

Jan 16, 2011

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.

Ubuntu Networking :: Wireless Disappeared On Netbook Remix?

May 8, 2011

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:
olamina@ubuntu:~$ sudo su

Fedora Networking :: Wireless Network Has Disappeared (F10)

May 26, 2009

After a few years of being a fedora user on a large network, I final decided to bite the bullet and dual-boot my home desktop (solely XP at the time) with fedora 10 on Saturday. The installation seemed to go well, but I am having a few problems, which solved themselves at one point but have come back and I have no idea why.

- I installed and re-partitioned with the install DVD, giving fedora 20GB. Having read a few guides and forum posts I wasn't surprised when the wifi and ATI graphics card didn't work. They appeared in the output of lspci, but I couldn't change the screen resolution and no wireless card was available.
- I bought a new wireless card a while ago but hadn't had time to put in so used this opportunity to do so (installed it in XP to check it worked) and when I rebooted, guess what, the resolution was what I wanted and I could see all the networks in the neighbourhood. I connected, downloaded/installed the myriad of updates together with a couple of programes through yum and went to bed a happy man.
- This morning (my router needed rebooting and after) I was back to the same as before the new wireless card, i.e. low resolution and no wifi. Having no idea what had happened, I check for loose connections, after that the resolution returned and the wifi worked but I can't see my home network.

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.

Networking :: Wireless Drivers/functionality Suddenly Disappeared - Kubuntu 9.1 HP TX1000 Laptop

Apr 18, 2010

I switched my girlfriend laptop from windows 7 to Kubuntu 9.4, then upgraded to karmic koala. I was able to, through the hardware manager, install a software modem driver, and a firmware unwrapper driver for her broadcom 4.X series wireless adapter. Whenever I attempted to install the broadcom 4.1, 4.2. ect driver itself a package update would fail, but wireless functionality still worked nonetheless. My girlfriend has a TX1000 HP laptop, similar to this one:[URL]..Product number in the bios is GA648UA#ABA System Board ID is 30BF

The wireless drivers she needs are proprietary. This worked for a while, although seemingly at random her wireless would go out, and her analog sound driver for her Nvidia chipsets would too. Usually logging out of the KDE environment and back in fixed the issue. Now wireless is completely gone; using a hard ethernet core to the router still works. Even connected to the internet, the proprietary drivers that used to be available in the hardware manager aren't there anymore. Right before the driver disappeared, I updated the system with all the latest round of updates, and installed the base package and some plugins for VLC. I don't know how to role back packages to see if an update killed the wireless, I uninstalled the VLC software but that didn't help.

Wireless is checked enabled on my taskbar, and I have checked my bios and haven't found any setting to disable the wireless adapter. Anything networking related has been enabled. At this point I am rather frustrated with the stability of Kubuntu overall and would prefer a hard solution that will permanently fix the problem.

Ubuntu Networking :: Virtualbox And Wireless Networking + USB Support?

Feb 17, 2010

Virtualbox, is great, except that I have no wireless networking or USB support. Problem one, is USB support. As far as I know there is a personal free use version of Virtualbox that includes USB support, however I can't find this copy to download it. Any ideas where I can find it? Second problem, I have an integrated wireless networking card in my laptop, that Ubuntu recognizes with no problems, but Virtualbox can't even "see" the device. I found a tutorial that addresses this know issues with wireless and Virtualbox, but I don't understand the instructions

[URL]

Quote:

Wireless Networking Setting up a normal bridged network generally doesn't work if you're bridging from a wireless card to VirtualBox. A simple script that utilises the parprouted tool will allow your VM full access to the wireless network. You will require parprouted to do this: sudo apt-get install parproutedNext, using your favorite text editor, create and edit the script, for example:

sudo nano /etc/network/if-up.d/vbox_networkThen, enter the script (replacing $USER with your username (or whoever you intend to run virtualbox as)). Replace wlan0 with the name of your wireless interface. Use an available IP address on your network for tap0 (I have used 192.168.1.100 in this case):

sysctl net.ipv4.ip_forward=1
VBoxTunctl -b -u $USER
ip link set tap0 up
ip addr add 192.168.1.100/24 dev tap0

parprouted wlan0 tap0Finally, make sure the new file is executable by root: sudo chmod 700 /etc/network/if-up.d/vbox_networkNow your networking script is installed, the virtual interface tap0 will be available on boot for VirtualBox. Rather than reboot, let's just run the script now:

sudo /etc/network/if-up.d/vbox_networkThe final thing to do is tell VirtualBox to use the new virtual device tap0. Open VirtualBox, highlight a VM and click settings. Now choose the network option and select Host Interface on the 'attached to' drop down menu.

In the Interface Name text box, enter: tap0 Click ok and start your VM. The VM should now behave as though it was another physical machine on your network!! For more information on the process up to this point, please visit Bridged Networking with VirtualBox on Linux Hosts Using DHCP in the Guest VM It was possible to get DHCP to work on the guest virtual machine. Instructions were taken from here. Because parprouted does not relay multicast, we need to use an additional helper daemon to manage this. I tried dhcp-helper and bcrelay, and had the most success with bcrelay.

Use it as follows:

sudo apt-get install bcrelay
sudo bcrelay -i tap0 -o wlan0At this point, my /etc/network/if-up.d/vbox_network is as follows:
#!/bin/sh
sysctl net.ipv4.ip_forward=1

[code]....

bcrelay -i tap0 -o wlan0 &It seems that I have to start the script by hand after boot. Other than that, host networking now seems to work fine (this issue should be solved by adding the "#!/bin/sh" line just at the beginning of the script.

Ubuntu Networking :: Wireless Doesn't Work After Updates?

Dec 12, 2010

I got Ubuntu 10.10 installed. Unfortunately, my wireless doesnt work. I'm connected to my router, but web pages wont load.

I thought to myself, maybe Ubuntu needs to update. So I lugged my computer out to the router itself and okugged my computer in. I went into update manager and let it do its thing. It was PAINFULLY slow. I had a less than 100 b/s. But I let it do its thing. After all 200 Mb's were done, which took a couple hours, I rebooted my system. Now, I cant even connect to my wireless and the internet symbol (the wireless bars thing in the top right) is gone.

1) How can I get my wireless to work?

2) How do I get the wireless button back?

CentOS 5 Server :: Updated Fresh 5.3 Xen Kernel And PAE Support Disappeared?

Aug 26, 2009

I have installed CentOS 5.3 with Xen on a PowerEdge 2650 machine with 6GB of RAM. As usual, PAE was already enabled so I did not have any problem with utilising all of the memory. However after upgrading to the latest release of the kernel (2.6.18-128.7.1.el5xen), memory available decreased to 4GBs. Then I switched back to the old kernel and 6GB was there. Then finally have switched back to the new kernel and 6GB is again there. So now PAE seems to be enabled but what concerns me is the inconsistent behaviour. (Also I am not sure the reason was the upgraded kernel.)

Ubuntu Networking :: Iwconfig/iwlist - No Wireless Extensions And Interface Doesn't Support Scanning?

Mar 11, 2010

The adapter I purchased (Zonet ZEW2508 ) uses the Ralink 2070 chipset - a fact that originally excited me because Ralink seems to be fairly loving to the Linux community. However, despite my best efforts I can't get the thing to work. Initially I tried following directions to set up the driver you can download from the Ralink website. The directions I found were written February first, and Ralink updated the driver February eighth - so as far as I can tell the directions no longer work. After screwing around trying to figure that out for a while I decided to give ndiswrapper a go.

Initially this seemed promising. I just harvested the drivers from the CD and followed one of the many ndiswrapper directions available - most helpful seemed initially to be the Ndiswrapper Troubleshooting Guide found in this forum, however the solutions offered there didn't work either. When I throw an ndiswrapper -l into the terminal it looks promising at first, it tells me the driver is installed and the device is present, but it just doesn't work. When I try iwconfig, or iwlist scan it tells me "no wireless extensions," and "interface doesn't support scanning" respectively. The only devices even listed are lo, eth0, and pan0. There's no wlan0 or anything of the sort.

Ubuntu :: View Wireless Networks Icon Has Disappeared

Jan 28, 2011

I just upgraded to Ubuntu 10.04 LTS from 9.10 and the icon that lets me view and choose wireless networks to connect to has mysteriously disappeared. I did the whole "Add to Panel" thing and added the "Network Connections" icon to my task bar, but for all the searching through that and other things like System -> Preferences -> Startup Applications, I just can't find a solution! The Network Preferences still has the list of all the wireless networks I have connected to in the past. It still connects to my home network automatically (although I did have to delete another neighboring network from the Network Preferences list so it only has one auto connection to connect to). So where in the world did my icon go? It was so great. Left click to see all local wireless networks and to connect. Right click to turn off networking or wireless.

OpenSUSE Wireless :: Wireless Doesn't Support Scanning

Nov 10, 2010

I am using an HP G60 laptop with a built in wireless NIC but am unable to get the wireless connection working. I have followed the advice in the sticky messages above and have included the information below. I know the wireless modem is working as I have got a spare USB wireless dongle running on the desktop (ironically - I can only get it working where it is not needed!!!). The same dongle will not work on the laptop. So it is a config thing and not a hardware issue On a trivial level, left clicking on the Network Manager icon shows the "enable wireless" greyed out. Desktop and laptop are running SuSE 11.3 and KDE4.4.4. I have tried the traditional method as well as knetwork manager and have no success with either. Here are the technical details.

Ubuntu Networking :: Wifi Has Disappeared In 10.10?

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.
