Ubuntu Networking :: Wifi Worked For A While Then Stopped Working - Can't Get Online
Jun 18, 2011
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 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?

I've been running ubuntu on my Asus 1001ha netbook for half a year or so. I ran Karmic for at while, wifi working and all, accepted the recommended updates when Update Manager popped up and everything was fine until one day I let Update Manager do it's thing and my wifi stopped working.. Lycid had just come out that same week, so I thought "screw it" and installed 10.04 instead..
So I've been running 10.04 for a couple of months now, everything working fine, including the wifi - until today.. Update Manager suggested some upgrades, I accepted and *pouf* my wifi is gone again..
That's the second time Update Manager knocks out my wifi, any way to roll back todays update or how to the the wifi working again?

I have a laptop that was working fine with 10.04 LTS. Today, I did a full 10.10 install and now my wireless is not working. Thinking it had to do with 10.10, I did a full install back to 10.04 LTs. Wireless is still not working. I tried installing the driver for my laptop's internal wifi using ndiswrapper, but that didn't work either. I have another laptop that is identical to the non-working one, with the exception that it is running a Celeron processor and non-Nvidia graphics. Otherwise, they are identical with respect to the wifi adapter. The Celeron machine is giving me absolutely no problems.

Since I originally started using Ubuntu (10.04) I have had problems with my wireless card. Now I have updated to 10.10 and it has stopped working entirely. I am using a "Dell Vostro 1520" with an "Intel(R) WiFi Link 5300 AGN" wireless card.Here are the details: 10.04
In this distribution version, if I had the wireless switch on my laptop activated at startup my wireless card would refuse to activate. There is a light to show when it is activated and this was off, but I checked anyway and wireless capabilities don't work when it is in this state. It didn't even resolve the problem when I switched it off and on again (although this caused the wireless indicator to blink on for less than a second when switched on).This was manageable because I found two workarounds:
1. Wait until my laptop had logged into Ubuntu, then activate the wireless card which would start and work as it should.
2. If I had already logged into Ubuntu I could put my computer on standby, switch off the card, come out of standby and reactivate the card while Ubuntu was running.As I said, this was completely manageable, and I got used to it. 10.10
Now that I have upgraded to 10.10 all workarounds fail, I can't use a wireless connection in Ubuntu, as my card won't activate, I cant even get the light to blink as I could before. The only way I can use WiFi is by switching to Windows.I tend to use Ubuntu for my university programming work.

i have a dell 1501 that has been upgraded from 10.10 to 11.04. everything was working okay. and then the user ran an upgrade recently. subsequently the wifi has mysteriously stopped working. it connects okay if one plugs it directly into the router but the wifi seems to have just stopped working.my mini 9 connects fine to the netgear wifi router using wireless.when i run the system tests for networking i get the errors..."root could not find def gateway info /proc""root could not find default gateway by running route"here is the output from some diagnostic commands.NOTE:this is similar to a post titled "wi-fi dead?" but the output is not quite the same...
lauren@lauren-Inspiron-1501:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

I've got a Dell precision with Kubuntu 9.10. Wifi worked fine on that machine for months, but stopped working last week. I don't know what happened, but I recently did an "apt-get dist-upgrade". That might have something to do with it.
When I boot in Windows, wifi works fine.
Code:
tijl@Smaug:~$ sudo lshw -C network

My Intel Corporation WiFi Link 1000 Series wireless card stopped working yesterday after I did an update via Update Manager.After the upgrade, wireless is disabled and the option to enable it in Network Manager is grayed out. I thought that it might be the new kernel, but changing back to the old kernel I still have the 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 an asus EEE 1015N. Everything worked fine yesterday. I packed my computer, and went back home. After turning it back on, not only it didn't connect to the wifi network, but it did not even detect it. I know it's not broken or anything like that because when I boot into windows it works fine.I've been trying every solutionven in the "sudden wifi problems" threads in the forum (including checking the wifi power button, and trying to manually assign an access point to it), but to no avail.

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 was uninstalling some programs through the package manager, then restarted. When my netbook turned back on, I had no internet connection and the WiFi icon wasn't showing in the notification area as it usually does either. Says the card is functioning properly and everything. Other devices can connect to the WiFi.I'm kind of new to Ubuntu and searched around a bit, but am at a loss. HP Mini 110Ubuntu 10.10Broadcom BCM4313Edit: Quote:$ sudo ifconfig -s

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.

Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.
I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?
The USB adaptor I'm using is a Trendnet TEW-424UB

I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).
When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?

Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.
However, this time nothing is working. I've provided some detail and if more information is needed, let me know.
