Ubuntu Networking :: Wireless Worked Before Update But Suddenly Stopped Working
Oct 14, 2010
I have an HP a670y desktop computer using the included wireless antenna (looks like a big Sorry game piece). I am running Ubuntu 10.04 x64 dual booted with Windows Vista x64. I haven't had internet for a while but just got it today and decided to do some updating in both Windows and Ubuntu. It had detected my router and I copied and pasted the WEP key then it asked for my password, but my keyboard wasn't connected so I clicked cancel for the password window and it connected anyway.
I opened the Synaptic package manager and started downloading some updates while I did some browsing on the internet. I had restarted my computer when the updates were done and it asked again for my WEP key. I copied and pasted just as I did before and entered my password and after it tried to connect it asked for my password again. I thought maybe the internet was down so I decided to boot up Windows and it connected right away. I wonder if one of my updates messed something up. Has anyone else had this happen?
When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
I'm running a gateway lapbook w/10.04 LTS and an etheros wirless card. Card has been working fine for almost a year - from cold boot, warm boot, and recovery from standy (shut lid, open, press power button). I was fiddling with setting a static IP for the wirelss card by modifying the interfaces text file. I made some changes, and restored the file to its original contents after some noodling around. Wireless still worked fine after that. Last night I took the laptop out of suspend as usual - lifted lid, pressed power button - but the wireless indicator remained grayed out and I haven't been able to reenable wireless connectivity since. ifconfig shows the wireless card is there, and cabling the e-net port directly to my hub works fine.
A few days ago (september 7) my wireless suddenly stopped working. I am using FC11, and have an Atheros AR5211 wireless card and have been using the ath5k driver with GNOME NetworkManager. Wireless networks are detected by NM perfectly fine. When I try to connect, the icon spins around those two dots, and one of them becomes green. If the network is wep protected, it asks for the password. After a while, it times out, regardless of the protection. I don't remember changing pretty much for the last two months, so I'm sort of surprised. I did download and install a kernal, along with an selinux-policy update.
If I run dmesg, relevant looking lines included:
ADDRCONF(NETDEV_UP): wlan0: link is not ready and a long series of these at the end: wlan0: direct probe to AP 00:0b:86:4f:8a:20 try 1 wlan0: direct probe to AP 00:0b:86:4f:8a:20 try 1
[code]....
Note: I previously posted this in "Laptops," but Networking seemed like a better place to do it.
I'm not getting a response over on the Ubuntu WIreless Forum (which looks like it's getting slammed with questions), and weigh in on whether or not you believe I have a hardware failure on my hands? As I state in the post, I ran fine from the original installed version, 8.10, through 2 upgrades (to 9.04 and 9.10). Now none of them work (When the problems began I re-installed each of them in turn in order to test).
A couple days ago I booted up my Ubuntu 10.10 machine as usual,but the wired LAN connection did not work; it doesn't seem to see any wired connection devices. I can still connect to a wireless network with no problem, and if I plug that same ethernetable into another machine it works fine. I've been happily using this setup for weeks; the LAN only stopped working a day or two ago. So I figure there's two possibilities:A recent update caused NetworkManager to stop working with wired LAN connections, but I'm e only persothed affected (unlikely)My motherboard's ethernet port died (this motherboard only a couple weeks old, so this also seems unlikely)I'm not good at diagnosing problems with networking, so who can tell me where to st
I had 10.10, and all was well. Then I installed natty, and WiFi worked for a while, then stopped working. I later went back to 10.10, and WiFi still isn't working. The WiFi icon in the top bar looks like it's scanning. But it just keeps on scanning, continuously. Then it asks me for the password, so it obviously connects to something if it knows the network needs a password.
But here's the weird thing, my router also creates a BT Open Network, which I think is some pay service that BT offer, apparently through anyone's wifi since it's not password protected. I can connect to that. But not the actual network that leads to the internet. This happened a while back, and of course I can't install any updates on it because I can't get online. I am writing this from XP on the same computer, and XP can connect to the network no problem.
I've been using Windows all my life (and still have to use it at work) but I made the big leap yesterday and installed Ubuntu on my personal machine (at last). With my "Windows-centric" mind, there are a million things that I still don't get, but I must say the community and forums look quite impressive and easy to access (kudos! ). I am testing this today!My current problem is with the wireless adapter. I have a Belkin N Wireless USB adapter (FSD8053v3) and Belkin, of course, doesn't make linux drivers. When I installed Ubuntu, it recognized it automatically and I could connect to my network, but navigation was very slow so I tried to install Belkin windows drivers using ndiswrapper. It worked immediately, and navigation was very fast. However after a reboot, I lost the connection, I can't even see any of the neighbouring networks.
i have lucid installed on my toshiba laptop after after an update my wireless stopped working keep asking for password and my wireless card is not detecting no wifi :
I have an EEE 1000 that successfully connected to WPA networks until yesterday. I tried re-installing the RT2860 drivers that had been previously modified and did not have success.
Additionally, I just installed 10.04 on a Gateway laptop that's a few years old. It immediately connected to the WPA network and I ran the updater. Lo and behold, after updating it no longer connects to the network.
Well, I have an issue with my wireless card in Ubuntu 10.04, my wireless card model is: the D-Link WIRELESS N 150 DESKTOP ADAPTER DWA-525. I was already successful getting it to work by using the RaLink driver suggested here and following the instructions in their readme.But after a system update I performed through Update Manager (in which I guess the kernel was updated), the device stopped working completely. The wireless icon remains(in the top panel), but it displays a red exclamation mark next to it
I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.
Only been using linux for about 2 weeks now. Yesterday my internet worked without a hitch now today all of a sudden it wont connect. I had the "Install problem! The configurataion defaults for gnome manager have not been installed correctly" so I deleted my music directory and now it boots fine, dont know if that might be part of the issue/ I dual boot win7 and i can get wireless on that partition but not ubuntu
Version: Ubuntu 10.04 Relavant hardware: P5QL Pro built-in ethernet, cable modem with linksys wireless-G router (although problem is with ethernet connection, not wireless)
One minute my ethernet was working, and the next it stopped working. The only thing that I did between it working and not working was install electricsheep from Synaptic and then I shut down the computer. When I restarted a bit later, no ethernet connection shows up.
I checked the cables, made sure they are in tight.
My laptop connects using the same ethernet cable fine. So its not the cable or the router.
I reset the router and the computer at the same time. Still doesn't work.
I don't know where to even start with troubleshooting this sort of problem. Everything to the extent of my computer knowledge seems to be working fine.
I installed Ubuntu 10.4 side by side with my Vista. This is on a PC I leave on permanently and use as a sort of Sever, so Security and Network connection are VERY important on this device. I use it for documents and IP PBX (telephone system). I currently use Vista and 3CX, but I plan to roll it over to Unbuntu full time once its up and runnng correctly - I will just need to change the Grub2 conf priority. After install, all was fine and I managed to make many changes to settings, apps and updates, but I have noticed in the past week when going in to make further changes the network has suddenly stopped working! According to Network Manager and the icon on the panel it is connected and I can not see anything obvious that is not correct. I tried doing a PING (192.168.1.1) from Network Manager to the main router, but it failed. I know that there is nothing wrong with the network nor the card or PC it all sits on. It's working now with Vista and my other machines. It must be a config some-where.
Right so yesterday my internet worked fine. Today - no connection at all. The light for my cable on the router doesn't even show up. I originally had indicator-network installed, so when the internet first stopped working, I tried a few other options such as tethering to my phone via usb and bluetooth (which I have successfully used in the past). However, these didn't work, and I figured that as connman is still in beta, maybe that was why. So I reinstalled network-manager and network-manager-gnome via a usb stick, uninstalled indicator-network, and rebooted the computer. Still no internet.
When I click on the applet, it says "No network devices are available". This is odd, as I definitely have a network device... it is part of the motherboard. So I thought I'd do the SMARTlan test or whatever it's called. It's part of my BIOS, so I ran that and it returned results that I (kinda) expected: when the cable wasn't plugged in, it returned one set of results. When it was only plugged into my computer (and not the router), it returned another set of results. And when it was plugged into both my computer and the router, it returned a third set of results. So that leads me to believe the cable itself is fine.
And when I move the cable to a different port on the router, nothing changes. The corresponding light still doesn't come on. Network-manager, telling there are no network devices. The BIOS can see the ethernet port and the cable. And the router is functioning perfectly for my parents' computer and my ps3. And I have checked the cable to my computer for physical damage - it follows the same path as the one to my ps3, and on top of that, nothing physical can possibly have happened to it in the last day. This happened once before, except I don't think the network devices were lost.
my Internet connection stopped working suddenly after updating the packages using synaptec package manager and rebooting it..can anyone say me why did this happen.BTW,mine is ubuntu 10.10 and i am absolute new to linux.I had to configure my n/w connections right from the scrap again
I have an HP Pavilion notebook with a Broadcom WLANcard that had been working very nicely in Fedora Core 10 until this evening, when I took my notebook to a conference room where there was no internet access. (I tried to connect to wireless networks, but there were none in the area, as I discovered.) am now unable to connect to my local (home) wireless network as the device is now non-existent . Can someone please walk me through the steps to fix this or re-install it (I have tried reinstalling broadcom-wl, but that didn't help). My lspci listing is reproduced below:
Code: 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03)
my eth0 suddenly stopped working on FC10. i have been using it the whole time, and now it refuses to even ping the gateway. dhclient is not receiving a dhcp offer and when i put in the information manually, it is not even able to ping the gateway. netstat -rn shows that the destination of the router is going nowhere.
i do not think it is the hardware/software, but rather maybe the provider? i am from central europe but just moved up to great britain and working at a friends place. i can connect the mac powerbook without a problem (it will get an ip with dhcp), but not the linux machine.it is a normal ethernet modem connection here. can it be, that it checks MAC addresses or even the computer names? the powerbook also has a really weired IP address: 77.102.xxxxx
i am not using network manager, but command line tools and have nm uninstalled. does anyone have a clue, what this could be about? i am not a newbie, but this is really puzzling me.....
I've been running Ubuntu 10.10 on this ThinkPad for a couple of months now, with absolutely no problems at all.The wireless was working fine earlier today out at a coffee shop. When I got home and turned the computer on, the network applet just showed a "Wireless is disabled" message.I poked around for a while, mucking with whatever I could (limited, unfortunately, I don't have great linux-fu) and doing the ritual reboot to see if that would get things going.I then spent some time reading through forum threads here, but didn't find any answers.Below are the results of the various commands as described in HOWTO post a Wireless issue (ticket) sticky threadMachine brand and model

I have 10.04 installed and Update Manager has worked fine for months, until about 2 weeks ago. When I ask Update Manager to update its indexes, I get this error message returned almost immediately
"Method http has died unexpectedly! Sub-process http returned an error code (127) Method http has died unexpectedly! Sub-process http returned an error code (127)
The internet connection is working fine on this machine. I have another 10.04 machine sitting right next to the problem computer, and Update Manager works fine on that machine. I verified that all settings are the same between the 2 machines in these areas
1. All Update Manager SETTINGS (including SOFTWARE SOURCES)
2. System -> Preferences -> NETWORK PROXY (which is a Direct Internet Connection)
3. System -> Preferences -> NETWORK CONNECTION
It appears to me that the connection to Ubuntu repositories is failing but I can't find anything different between the 2 machines.
I've been running Ubuntu 10.10 (Maverick) x64 quite happily on my Dell e6500 for the past few months until today when I woke the computer up from sleep mode and could not use the wireless. The network-manager applet simply has 'Wireless' greyed out. I tried rebooting, thinking it was an issue with the wireless card not re-powering on properly after sleep, but to no avail. how to begin here?
i'm running Kubuntu karmic and i've been using a 3G Huawei E1552 modem to connect to the internet, everything was going well when suddenly my modem stopped working. I've tried reconfiguring everything, i even reinstalled kubuntu from scratch with no success.Here's a part of my /var/log/debug

I am running Karmic on a Compaq Presario V3000 and this morning my wireless card is not being detected by Ubuntu's NetworkManager. I have no idea what caused this... literally, it was working when I shutdown my laptop last night. When I right-click the NetworkManager icon in the panel it does not show "Enable Wireless" (only "Enable Networking"). When I run ifconfig in terminal it shows my wireless card as being there (UP Broadcast Multicast). One weird thing - on the front of the laptop there is an LED which lights up blue when the card is working (ie normally), but right now it is orange (ie, if you flick the switch on the front of the laptop to toggle the wifi on or off... I have toggled it back and forth but nothing changes!)
I have been using ubuntu troublefree for some month, but yesterday, suddenly the wireless internet connection stopped working. It happened after i used the turn off wireless network shortcut, now i cant turn it on again (usually this works fine).The situation is now, that when i click on the tray icon showing connection it says, wired network disconnected (it never said this before), then if i click on the wireless shortcut it also says wireless disconnected... But if i click again it doesnt show connections, the disconnected sign just disappears...?
Ubuntu and I'm using the latest stable version. Yesterday I had my sound working, but today my sound has stopped working.I've taken the following steps without success:System -> Administrator -> Hardware Devices (finds nothing)
