Ubuntu Networking :: Installed 10.04 And Lost Wireless Connection Right After Updates?
Jun 6, 2010
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 initially loaded Fedora 14 onto a Desktop and started to configure it to be a server but as soon as Iso software updates My network connection completely drops.
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 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 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.
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.
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 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.
I installed ubuntu 10 just yesterday. Everything was working just fine. The auto-update function advised me to download and install the latest updates and so I did. It was over 300 MB. I installed it, did a reboot and my internet connection was lost. I tried a few things I found on this forum yesterday. Nothing worked. I can go on-line on the same computer using windows 7. But I always have to reboot to try the different solutions. All right that's fixed! But now I just have to fix Firefox...
Three months ago my daughter went off to college with a new computer. I zapped her old system and successfully installed Ubuntu 9.04 from a CD. Everything worked fine including all the peripherals and the wireless internet connection. I was able to download and update applications without a hitch. Great system and so much cleaner and quicker than Win XP on the old machine. Then the system was shut down and lay idle for three months.When I fired it up a couple of days ago, all seemed normal except I could no longer access the internet even though the wireless network icon showed four or five bars. I first discovered the problem when I tried to update though Update Manager and noticed that 22 identified files could not be fetched. Neither Firefox, Skype nor Goodgle Earth can connect.
The router is a Linksys WRT54G router that connects to the computer through a Linksys WUSB54G USB network adapter. The router serves three other non-Linux computers without a problem, including one using the same model network adapter.I don't have much experience with Ubuntu, but this is some of the information I have been able to generate.
I tried a few of the recommendations found in other sites, but nothing seems to do the job. I am perplexed because everything was great until I shut down the system for three months and then started it up again. I appreciate any assistance and would be happy to provide additional information as requested.
I installed flash player for my daughter and lost all my icons. I did " sudo gnome - panel restart and got them back , All but the wireless icon and I do not have a clue how to get it back. I also need to know how to get my pc to see the ubuntu os on the same network and how to view its traffic as part to police what my daughter is doing.
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.
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 just installed ubuntu 10.04 on my laptop. everything was working fine until i installed firestarter. i didnt like it and uninstalled it. when i did that i lost my wireless signal icon at the top of the screen, firefox starts up in offline mode, and limewire says that network connection is lost. i just want it back the way it was before installing firestarter. please help, i dont want to reinstall ubuntu if i dont have to.

I have tried to force mount but no luck.
The connection/network icon that showed next to the clock is gone. i told it to "move", but instead it removed. grrrrr. now when i go to add, i dont see it. same with email.
I downloaded ubuntu 10.10 in my PC alongside with windows 7 yesterday. However it could not detect my wireless LAN then with some hardwork I was able install the wireless device driver but still no internet!
I recently installed Ubuntu 9.04 off of a disc and it worked perfectly, however after I downloaded and installed the system updates from the update manager, it stopped working and it won't even see my device. I have a Zonenet ZEW2500 USB wireless adapter.
recently i have combined 2 machines into 1. after doing this, the ping to the new machine stops, for no apparent reason, and consequently all traffic to/from the machine also stops. when using the two machines individually this never happened.Lastly, if i restart the network, it kills everything (like the network just wont restart - it reaches the last interface and hangs), and if i reboot the machine, it seems to be fine for about 3-4hours.has anyone seen anything like this when connecting a large number of hosts to 1 gateway, using linux as the router?
I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.
My ISP pushes software updates occasionally to my router. This also forces the router to restart. When the router restarts, my ubuntu box loses its network connection and does not automatically restore it after the router comes back online.How can I configure ubuntu to restore the connection once it is available again? It happens on my windows workstation...I am using ubuntu on a box with no screen / keyboard / mouse it serves as a fileserver and I remote desktop in. Obviously if the box drops the connection it is a major annoyance. I am using version 9.10
So, when I booted up, the wired connection was automatically detected and in use. Whenever I suspend my computer and then resume it later I lose the wired connection. It is detected (seen) by Networkmanager, but I can never connect. I found a way to restore the connection, but it is manual and I was wondering if I could automate this process every time I resume. Details follow:
I was running 8.04 and my internet (Comcast) comes via a Motorola SB5100 cable modem then into a Netgear router then into my Dell. When I upgraded to 10.04 yesterday, I lost the wired connection. The wireless connection still works fine, but I have not been able to get a wired connection. Also, most online solutions reference the Network Manager, which is nowhere to be found.
Anyone have any solutions? I would be willing to revert to 8.04 if needed, as that worked fine, and obviously I quite regret the upgrade!
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,
I installed Fedora 14 in my HP laptop (dual boot, with Win7). After reboot, I don't get wireless connection (wired connection is fine). The wireless connection in Win7 is fine. I am just not able to get it in F14.
I recently had my AE 1000 linksys wireless adapter driver installed, the info for which can be found here:

But today I was presented with 142 automatic updates already downloaded waiting to be installed on my computer. I installed the updates and restarted my computer for the updates to take effect. Well, since then my wireless adapter no longer registers at all, it doesn't even recognize my router let alone connect to it. It is as inoperable as the day I got it.
I am currently using a different computer in the house to get internet. Should I go about following the same directions I did before and reinstall the driver, or is there a more simple way?
I have a server which is located in the basement. The server exports a few directories which I mount on my desktop using NFS. From time to time, the connection gets lost. The server is also not always on. I can't change that part, so I worked out a script which notifies me when it's going down, and when it's back up again. It also mounts everything back.However.. As soon as I loose the connection, my desktop seems to be gone. KDE doesn't work, but I can use a few applications like Konsole, google-chrome, firefox, stuff like that. But the plasma-desktop around it hangs.
As soon as the connection gets back again, everything works. I have this issue only when my desktop is running while I loose the connection to the server. If it's down when I start my desktopworks properly. Unless the server comes alive, the nfs directories are mounted and the connection is lost again.I'm not really sure if this is a networking case, it could also be KDE related, but I figured this was the most reasonable place to put my topic in.My hardware:
I have had long term access to a networked HP Photosmart printer but now I get the following message:
Unable to open device hp:/net/Photosmart_C5100_series?ip=192.168.0.161.
when trying to access it.The ubuntu desktop is wired to the router as is the printer and another iMac wirelessly can still print to the HP. HPLIP status shows the icon for the printer but with a red x indicating no connection to it.The only recent network change was the removal of another router from our network. (service is DSL via a combo modem/router from service provider which previously was connected to a Dlink router which has now been removed from the chain b/c was redundant to the modem/router)
