after giving me no problems whatsoever (currently 10.04 Lucid Lynx) I lost wireless connectivity on my laptop after the following updates were processed yesterday:

but as it all worked fine before and this was just an update not an upgrade I suppose drivers etc are all OK anyway.
Also, rfkill showed nothing was blocked to need unblocking, and ifconfig gives a permissions error
I have a wired connection operating without any problems at all.
A friend who switched ISP's gave me his old Linksys WRT54-G wireless router. I went through the installation procedure and had a wireless connection up and running - smiley face. I had security set up for WPA, and decided to upgrade it to WPA2. Another smiley face. When I went to connect (had already done so successfully), I noticed it referred to my wireless as Linksys - I was expecting to see the SSID. So I started playing around in Network Manager and now I have things all effed up.
Don't know exactly what I did, but now I have no wireless. So I ran a few commands (lshw -C network, iwconfig, ifconfig, and iwlist scan), and looking at the results I see what appear to be inconsistencies in the output. I've posted them below, and make the following observations:
1. Under the lshw it refers to my wireless connection logical name as wmaster0, and has the correct MAC address, etc.
2. Under the iwconfig it says, 'wmaster0 no wireless extensions', but then refers to wlan0 as the wireless connection (although it does not seem to be running).
3. Under ifconfig I see both a wlan0 and a wlan0:avahi. The wlan0 has no IP, the wlan0:avahi does, but it is incorrect.
I'm relatively new to Linux. My netbook ran updates yesterday for Ubuntu and now I am unable to reconnect to wireless network connection. I am using WPA2 encrypted security. I am able to connect via wired LAN. Also, when I went to connect using USB mobile connection, I get an error "unable to mount location". I get the same error if I try to connect my external CD drive. I am using Ubuntu 8.04 with Gnome desktop (2.22.3) on a Dell Mini 9.My wireless device is using Broadcom STA Wireless driver for an 802.11 wireless card.

i have a acer aspire one (zg5) with a 2 week old installation of unr. shortly but not immediately following my last update my wifi no longer functions. when i go to the network connections tab in my toolbar it does not list available wifi networks. does not apparently recognize wifi capability at all. but the wifi worked right off the rip on new install.
After I updated ubuntu 10.04.3 and restarted my PC, something weired happend and my wired connection was completely lost. I tried different things but it seems that I have lost my ethernet connection. I only have ethernet card and the interface was set to eth0 which is not recognized anymore.
The /etc/network/interfaces includes the following commands, which btw I tried to play with a bit by commenting and uncommenting the lines but was not helpful (but this is the original one):
Also in /etc/udev/rules.d I deleted 70-persistent-cd.rules hoping that it would be automatically regenerated but it did not,
After running a large update and rebooting a few weeks ago, I found that my internet connection had stopped working. My internal network still worked fine though, so it I know it's not the card itself or its configuration. After a bit of trial and error I discovered that simply running dhclient brings the connection up again, so it appears that something is interfering with the initial dhcp update to my ISP (or something like that; I'm no expert in this area. ) My usual policy in cases like this is to wait through two or three updates in the hopes that it's just a temporary problem, but it's been a while now and subsequent updates haven't fixed it.
I've tried looking around, but I can't come up with search criteria specific enough to narrow it down to my specific situation. I'm not even sure where to begin looking to diagnose the problem, nor do I know which package update(s) could've affected it. I'm not sure what might be useful, but here's the relevant entry in /etc/network/interfaces. I have it configured with a static internal address, with my router as the gateway.
Right after playing Assult Cube, I lost my wireless. Folling the directions from this sticky, the information is listed below. Any ideas as to what I can do to get my wireless back?

Running Ubuntu 10.10 on a Dell 710m. Fresh install of OS yesterday. Initially I had wired connection but no wireless. So I started chasing threads & trying different downloads & commands [WITHOUT KNOWING essentially what I was doing; throw your rocks at me HERE] & now I have lost the wired connection also.
Also: [a] If I go into System > Administration > Additional Drivers, I get "No proprietary drivers are in use on this system."
[b] As far as being able to copy a downloaded driver [using a working M$oft machine with net connection] onto an SD card & transferring that driver to the Dell laptop, I have tried formatting 3 different SD cards with the Dell, & each time I come up with various failure errors--& I have no idea why something as simple as formatting an SD card isn't working.
I used to be able to connect to the net using my laptop {Ubuntu 9.10 on Compaq nx7400.}by means of wi-fi . I do not know what I have done but I lost the facility to connect to the net.I noticed the Network Manager disappeared from the notification area. I manged to put it back. It detects the signal from the router and after entering my password it displays Connection Established but I still cannot access the net and does not load any web pages. I have the same Ubuntu 9.10 Desk on a memory stick, when I use it on the laptop it works fine.
I enclose a screenshot of iwconfig.I did sudo lshw -C network and it shows DISABLED. How do I enable it ? Are there any other info that I should supply and what and how.
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.
I installed a clean installation of ubuntu 10.04 inside Windows 7 and wireless worked normally in the beginning that I downloaded and installed all the updates "I selected without updating Grub".On the first reboot after updates, the wireless icon disappeared from the panel and could not connect to the internet although the settings in the Networking tools were correct.
i have a sony vaio VGN-NW150J laptop that was running lucid and had wireless no problem but when i upgraded to maverick i lost all functionality of my intel 5100 agn wireless card. when i run iwconfig this is what i get
Code: iwconfig lo no wireless extensions. eth0 no wireless extensions.
and on bootup it flashes something about no suitable unicode found i can't get a good look at it maverick boot up too fast.
I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.
It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.
My wife's laptop is Dell Inspiron 6400 running 11.04. Wireless has recently stopped working. Running rfkill list all shows dell-wifi hard blocked no soft blocked no. The fn plus F2 keys toggle status between blocked no and blocked yes, but network manager still can't see network. I've tried removing the Broadcom STA driver - no joy.
I just installed some more updates a little bit ago through automatic software updates and now i seem to have lost my wireless...I tried to see if i could reinstall kmod-wl but it said i had it still...Is this another thing that a lot of people are getting?
I have an odd problem in that my wireless connection is okay until I close the laptop. When I open it back up, I'm unable to reconnect. This problem first occurred after upgrading to 9.10. I can reconnect after restarting. I tried several things before breaking down and reinstalling 9.04. After installing 9.04, everything works great. Any suggestions on what is going on before I try upgrading to 9.10 again? I have a Dell D600.
I suppose this was caused by an update, I don't know. I just know that my wireless card is no longer seen by my Ubuntu 8.1. Maybe I should be in the newbie area. Isn't there a way I can wake it up with modprobe?
I have fedora 10 and am having problems with the wireless access. My computer uses the Realtek Semiconductor Corp. RTL8187B Wireless Adapter. It connects to the network, it gets an ip address and a broadcast address, but it loses connection within 3 min. I'm also new dealing with linux and fedora.
Creating a new thread for the specific chipset. Laptop is an Acer 5534 with the Atheros chipset. Normally uses the Ath9k driver. To get it to work originally I had to download, compile and install the latest compat_wireless drivers. See post here: {URL] I did the update that came through today and after the reboot there was no wireless internet. It alternates between reboots between having no wireless networks at all detected to never connection to the [AUTO] network previously defined. To fix the problem, I downloaded the latest compat_wireless, compat-wireless-2009-12-11.tar.bz2, and followed the same procedure. I did not do a make clean. To solve the problem temporarily, I edited the grub config and set default to 2 instead of 0 (1 would be 0 in recovery mode).
I have installed xubuntu with wubi from XP. The installation was OK, I have booted the system several times with no problem, all devices worked well. After a day, auto update have shown that I have lots of packages to update. I said OK, let's do it. After a restart the wifi led was not lit anymore. I am unable to discover any wifi networks.. Fortunately I still have my old XP to write to the forum.. What can I do? The hardware: Compal CL56 notebook with Intel Pro 2200BG wifi. (and ATI Mobility Radeon 9700 - which will cause the next problems.?)
I've been running Ubuntu 10.04 x64 for about a week now, and it's been working flawlessly until today. This morning when attempting to connect to my wireless network, I click on the wireless icon (which currently has an ! next to it), find my network, and it begins to seem as if it is connecting, but then a pop-up comes up stating: "Wireless Network -- disconnected". No matter how many times I restart or attempt to connect to the network, it will not connect. I can see that the adapter is working, as it sees my network and others; however, it will not connect, it continually seems as if it's trying, then the pop-up comes up stating it has been disconnected. Here's my info:
Running on an HP Pavilion dv4...

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...
I am running UNR on an Asus T91MT and everything was working great until an update yesterday, my OS froze while updating and I had to do a hard reboot. Since, I have not been able to get wireless, and lshw does not even recognize the presence of a wireless device on the system.
I am using an Intel WiFi Link 4965AGN built in adapter.
When I was prompted for a system-update I clicked Update and apparently something failed an only a partial-update happened. Now my wireless/Ethernet connections do not work. I tried enabling all Network Adapters but that option is no longer available in the "Preference/Administration" tab.
Note: I cannot access the internet at all on that partition so I can't download any updates from repositories.
10.04 was connecting to wireless on boot up without a problem.After updating, it can no longer do it. I have to click on the wireless icon (which has an exclamation mark through it) and connect to hidden. I can then choose my wireless profile and am asked for my elevated privileges password. Once supplied, the connection is made.I presume the encryption password is 'locked' now at boot.
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:
