Ubuntu Networking :: Wireless Not Working After Hardy Update?
Feb 9, 2010
I configured my Xubuntu laptop to work with my Netgear Wireless router to connect to the Internet. I was able to connect, and downloaded Hardy updates of 184 MB. After installation of the updates, the system prompted me to restart. The Wireless network is not working since then. Tried reconfiguring, but to no avail. The proprietary drivers for my wireless network card have been downloaded and installed... remember, it worked well enough download the updates! Posting this from my Windows partition using the same wireless network A previous thread [URL]...k+Hardy+update) with the same issue seems to have hit a roadblock...

As the title says i updated my system which then needed a reboot. I also installed Mixxx djing software to try it out. So i thought id just restart the system. Usually when i boot into my desktop wireless automatically can connect to my router but not this time, wired only for now... i know theres tons of wireless issue threads but some more experienced users will be able to get straight to the point and run through some diagnostics with me.

yesterday I let the update manager install a whole bunch of updates for my 10.04 install on my MSI Notebook ER710. My wireless was just working peachy until then (with the madwifi drivers), but after the update, no more... I checked the madwifi, tried a new make, but nothing worked.
So, after reading somewhere that 10.10 had less issues with wireless I decided to upgrade to 10.10 in the hope that that would solve my problem.
Well, partly it did, as in, according to my system I've got a wireless again and this morning even, it was able to see wireless networks! Unfortunately I couldn't connect to mine, although the key was correct. At some point I lost the ability to see wireless networks again. I tried wicd too, but no luck their either. It recognizes my card but can't see any networks.
here is all the info:
Machine Brand and Model (PC/Laptop): MSI ER710

Code:
02:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

There is a realtek rtl8187 on my board, and windows can browse and connect to wireless networks. I installed F11 and it was capable of browse and connect to my wireless network - even if it was really slower than windows. Anyway I did some yum update+reboots and now NetworkManager don't list any wireless network, and the checkbox "Enabled wireless" in the right click menu disappeared (I can see "Enable networking" only now). What can I do?

I have a laptop Acer aspire 5100. I installed Ubuntu a while ago and it was working well. Last week I updated it using Update manager and ever since I haven't been able to connect either wireless or wired connection.
I get this:

The wireless card seems to have disappeared.
I reinstalled Ubuntu and the problem persists.

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

recently installed 10.04 on his hp pavilion laptop and we got everything working fine, including the wireless internet. When he installed some recommended software updates his card is no longer being detected although wired networking is still fine.

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 updated Ubuntu to 10.04 after which I noticed the wireless indicator lights on my HP laptop were continually flashing between blue and orange and network performance seemed slow. I did some searching and found and implemented the following change to stop the flashing:
gksudo gedit /etc/modprobe.d/wlan.conf
Copy and paste the below line:
options iwlcore led_mode=1
Since making this change the wireless connection is shut off and I can;t get it to work at all. I first tried simply to remove the change to get back wher I was, but I can;t do that. Can sopmebopdy toell me at least how to get rid of this wlan,conf file ( it was created by the above command) so I can start over?
Coincidentally since making this change my Windows Vista OS fails to start because of errors attributed to a software or hardware change, of which there were none other than the Ubuntu wlan.conf change. . It may be unrelated but I am suspicious of the coincidence. I am running Vista and Ubuntu in a dual boot configuration and all ha run very well until I did the Ubuntu wlan.conf change.
I am now attempting a complete recovery of my Vista system, since it seems irreparably broken. Again coincidence or not?

I've had issues with the later versions of Ubuntu, so in an effort to road-test Firefox 3.5 on Hardy I'd like to change my Karmic/Hardy dual boot to a Hardy/Hardy dual boot, and follow the instructions in [URL] to put the Mozilla build of 3.5 on the new installation.
I can't see any reason why a Hardy/Hardy dual-boot shouldn't work, but does anyone know of any issues with this I might not be aware of?

I just lost the sound to Xine after updating Hardy. It works fine otherwise and I have sound with Totem and VLC so it would seem to be a Xine-only problem.

I have a Hardy which last night asked for updates that included kernel changes. Today I find I no longer can connect using WIFI and have no sound. The GUIs are just not there and it's as if the controllers themselves have disappeared. For example lshw -C network reveals a Cisco Airon Wireless, but it's not listed as a wireless device, just as network controller.Can anyone advice me on how to approach this? Is it possible to revert changes or something?

just installed hardy after I removed Maverick since it doesn't support my ati graphics. I installed it inside my windows xp pro and run smoothly after installation, added couple of widgets and so on... after I restarted it the next time, a balloon showed on top saying 113 or so updates are available, so I updated it.
After update I reboot my lappy and it won't get to my ubuntu anymore but works fine with my xp. I tried several searches on the net to find the solution but can't really figure it out. I just tried running Boot info script as it might help experts figure out what's wrong with my box and here's what it shows:

I know 64 bit Flash has been a headache, but mine was working until yesterday. Symptoms began with it not working in Opera and Seamonkey. I checked the Adobe site and found what appears to be a later version, so I downloaded it, extracted it, then copied it to the relevant directories. That changed nothing at the time, but this morning it stopped working in Firefox as well.

After installation, I had no problems using wireless. Next, I added a new user (with administrative access). Now, when I log in as the new user, nm-applet doesn't appear in the panel and there is no wireless access. I've tried adding the Notification Area (nothing appears), making sure that the new user can connect to networks, etc with no success. System Monitor shows that nm-applet is sleeping. When I restart and login as myself, everything is still working fine. Computer: Computer: Dell Latitude D600

- OS: Win XP Pro & Ubuntu 10.04
- OS: win XP pro 32 & Ubuntu 10.04

What additional info should I provide to assist diagnosis?

I have been looking around the forums searching for similar problems, it seems not only me had this problem. About a month ago I did a regular update via Upd Manager. The next day - no wired connection.Still managable, since the local library has wireless. Now that won't work either.Just after I upgraded from Jaunty, I accidentally removed NetwMngr from the top right corner of the screen, but that should not have anything to do with how the program works, right? I now cannot reach NM, if I run it from the terminal, nothing happens visibly.

using Hardy Heron on a old Thinkpad T41.This is a fresh install system and I noticed it kept dropping wireless connection. After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time.
fter checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection?I found that extremely weird..
Code:
Apr 30 06:24:32 support kernel: [ 961.236895] e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang

I want to switch my laptop from XP to Ubuntu, but right now, i cant risk installing it. i dont want to have it partitioned so i can dual boot, so for now i only run the try-it-out mode.Before i consider installing though, i want to see if i can get everything to work ahead of time, that way im not regreting instalation. I have a Compaq Presario V2000 laptop, with 55GB hard drive and 516MB ram. So far, the trial mode is working great, but the wireless will not work. Ive tried to install the driver, but i am unable to do so. I have looked this up, and i have tried many things, and so far, none have worked.I was wondering if it was just part of the trial thing or not, but it is a Broadcom Wireless BCM4318 driver

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.

For some reason, i just cannot get my wireless to work in xubuntu. When i click on the network-manager applet, it only has the wired network tab and VPN connections, there are NO wireless networks displayed. I have also tried iwconfig, which returned

I reinstalled Ubuntu on my HP pc-40 computer. I used to run Hardy Heron and am now running Karmic Koala. The cd drive which had had issues for a while, broke after finishing the install, when I tried to get the cd out.I dont know if this has anything to do with it, or if my computer is too old for Karmic Koala, or if possibly the harddrive didn't appreciate being overwritten a second time - but the graphics are not working well (small squares of previous windows linger in my present browser window*)everythin is much slower, and many applications come up without a border, or their windows cant be moved with the mouse.
To top it off, while I tried to fix a bug with the terminal (no border) and uninstalled it, I couldnt install it back. So no terminal, which really makes even a newbie like me sad.If I cant solve it in a few days I will probably try to install a smaller distro via USB - I think Slax can be installed straight to USB without a live cd?

I've been enjoying wireless for a long time on Squeeze (iwl3945) with KDE, but the recent network manager update stopped that. I've tried a few things, like going back to /etc/network/interfaces and ifup wlan0 that I use with Lenny, but still not working.
