Ubuntu Networking :: 11.04 Broke The 10.04 Wifi?

Jun 8, 2011

I installed 11.04 from disc for a clean install on my dual boot vsta/ubuntu desktop.I was so frustrated that i had no wifi in 11.04 that i got out my 10.04 disk and triple booted that into the mix.Still no wifi (axcept in Vista) however if i unplug my usb wifi device and replug it in while in10.04 i will get the 'connection established' info box yet when i try to open Firefox i get the 'no internet connection or check firewall setting' drop down box.My wifi was working in 10.04 previous to 11.04 install.Note the unplug/replug usb does not work at all in 11.04.Also its strange that my wifi icon in 10.04 went from the bar graph style to the radiating arch style since the reinstall,even though i used the same install disc as pre 11.04

Ubuntu Networking :: Wifi Broke After Updates?

Nov 27, 2010

I got help getting wifi working on a Toshiba laptop with 10.10. After an update came through and I applied it (I believe it was a linux kernel update or generic headers update) wifi stopped working.I followed the steps in the post to re-create the driver but this time it doesn't work. So 2 questions:1. How to re-create the driver after this update?2. How to prevent this from happening again? So that another update doesn't make the driver not work?

Ubuntu :: Broke WiFi By Kernel Upgrade / What To Do?

Jan 13, 2010

I'm running Ultimate Edition 2.4 on an Acer Aspire 3500 lappy, yesterday I allowed my system to upgrade the kernel (from 9.10 kernel 2.6.31-17 to 2.6.31-18 generic) as per usual but when it rebooted I had no WiFi. The network manager didn't even have a wireless section, only wired, and I couldn't setup a wireless network either. If I reboot into the earlier 2.6.31-17 kernel everything is OK.
Another problem is that even tho I have no screensaver enabled and no power saving options enabled, (ie screen never disabled) after a short time of no use the screen goes blank. If within a few minutes I touch the pad or hit a key the screen returns but if it's been an hour or so nothing I do will wake it up,even tho there is still disk activity etc, and the only way to recover is with a hard reset, hold power key to reboot.

OpenSUSE Install :: Broke Gnome In 11.2 - Connect To The Internet Via Networkmanager And Couldn't Get Wifi Or Wired To Work

Apr 27, 2010

I was having a problem with cairo dock, asked on the board how to resolve was told to reinstall the visual driver for my monitor since I have an ati vid card since with the updated kernal u have to reinstall those drivers(didn't know that, I'm new to opensuse). I thought I did that before so I completely uninstalled it so I could then do a fresh reinstall but I wasn't paying attention and my laptop was unplugged for a while. I stepped away while the install was going on and my laptop died.

I tried plugging it in but had to restart my laptop when I did I got the command line rows and when I tried to start GDM it wouldn't start, I did so as SU. Attempted to connect to the internet via networkmanager and couldn't get wifi or wired to work. Anyway I can access my desktop visually just so I can start yast and install the driver or will I have to reinstall 11.2 or use the cd to repair? If so how do I use the cd to repair?

Ubuntu Networking :: Stop Wifi Radio Killswitch From Disabling USB Wifi Device

Jul 3, 2010

My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.

Networking :: Debian Testing (Wheezy) Update REALLY Broke Networking

May 8, 2011

The update that broke things contained some 400 packages.The problem is NOT hardware related. There are 2 other linux installs on the laptop that work the way they should.This is all related to using a wired network connection.The update removed the package network-config and did not replace it. Not sure that is the problem because that package is related to the gui and I can not get an ip in cli.

I am stuck at cli because the new kernel broke nvidia (pretty normal). There was also a new xserver, which tends to break nvidia, and as I recall a new kde. Anyway I am unable to rebuild the nvidia driver because I can not establish a network connection to my network to get the packages needed to fix it.

Ubuntu Networking :: Intel 5100 WiFi Card - Dell Latitude E6400 - Suddenly WiFi LED On The Computer Stops Blinking

May 4, 2011

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.

What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.

On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.

My exact hardware:

Code:

I notived the following problems in /var/log/kern.log

Networking :: Using Ethernet To Power WiFi Network And Setting Up WiFi?

Aug 23, 2009

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

Ubuntu Networking :: 11.04 Broke Wireless / Sort It?

Apr 29, 2011

I installed Natty on a second partition yesterday to try it out, but i can't get wireless to work. Hardwire connection works fine, so does connecting wirelessly to my router. However, i cannot browse the internet or update. After rebooting a couple of times i was surprised to see internet working, but only for about half an hour. Then it stopped working again. My card is a Intel PRO/Wireless 4965AGN and i'm using the 64 bit version of 11.04.
So my question is if anyone has had the same kind of problem or maybe knows a fix?

I'm really disappointed cause Ubuntu worked out of the box for me since Hardy.

Ubuntu Networking :: Update Manager Broke Ethernet?

Mar 9, 2011

Writing this from a 9.10 LiveCD, so I know that my hardware is working fine.My system is running 10.10 normally. Last night, the update manager popped up, as it frequently does, and said I had some packages that could be updated. So I let it update after which it said I needed to reboot. So I did, and now it doesn't recognize my network connection, and even the blinky lights on the port itself stay dark. don't know a lot about networking or stuff under the hood, but I can work a console and/or text editor if someone can tell me where to look and what to type.My hardware is (from "lspci | grep -i eth"):02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)The packages that have a modified date of last night are:

Ubuntu Networking :: Freenx Update Broke KDE On Kubuntu 10.04?

May 25, 2011

After a recient update to the freenx libraries KDE on Kubuntu 10.04 stopped working but other desktops like gnome kept running. The problem wasn't in the normal log files, but it was found in the .xsession-errors file in the user directory on the server. After the update NX is trying to start kde with the /usr/bin/startkde4 command which doesn't exist. Instead make a link from /usr/bin/startkde to the non existent /usr/bin/startkde4 and it will work again. To do this use the command:

Code:

sudo ln -s /usr/bin/startkde /usr/bin/startkde4

Ubuntu Networking :: Kernel Update Broke The Network Driver

Dec 23, 2010

I managed to get my Linksys AE1000 USB wireless adapter to work on Unbuntu 10.04 LTS.but recently I updated the kernel to 2.6.32-26 and when i rebooted I logged on to see my wireless connection was not working.even worse, I can't fn the links i had that showed me how to install it in the first place, its about the fact that the new kernel uses a different usb setup(probably incorrect, let me know it its incorrect). its an issue that the hacked driver isnt compatible with the new kernel release, how can i revert to the older version that it did work on? i'm using a RALinkTech driver [URL]

Fedora Networking :: Security Fixes Broke Wireless?

Mar 14, 2011

I am running Fedora 14 with KDE on my IBM T60p Thinkpad laptop. The wireless network adapter is Intel PRO/Wireless 3945ABG. The wireless network uses WPA2 with AES encryption.

Until yesterday my wireless worked fine. I originally installed wlassistant and it enabled my Network Manager to work with WPA2. My XP on the same machine still works on wireless without any issues, so both the adapter hardware and the router are eliminated as sources of the problem.

Yesterday I booted up my Linux and noticed there were 20+ security updates and I installed them all. It asked me to logoff and log back in. I did, and since then my wireless is dead as a doorknob. When the wireless adapter initializes it prompts me for the WPA2 password, however the password is visible in the password field. I click to accept it but it cant connect. Network manager just sits there waiting for authentication and nothing happens. The wpa_supplicant service is disabled, however I honestly cant remember if it was enabled before, considering that I use wlassistant. If I enable it, still nothing happens.

Anyway, thinking that the security updates possibly broke wlassistant, I uninstalled it and installed the latest version. The old version was 12, the new one is 13. It makes no difference though.I always use my laptop on wireless, therefore I am dead in the water.

Its really frustrating how something always breaks on this OS. It resembles a leaky boat that always has at least one hole. By the time I plug it another one appears, so I spend 90% of my Linux time fixing problems and have the remaining 10% for work and play. Windows and Mac work out of the box and apparently thats what 99% of users want, hence the 1% market share

Anyway, sorry about this, however losing my network connectivity from installing security updates really ticked me off. Its pretty unacceptable. Anyone has any ideas which recent fixes may be to blame? I am sure it didnt only happen to me.

Fedora Networking :: Yum Broke Wireless - Network Manager Crashed

Apr 30, 2011

So, after doing a 'yum update', I minimized the terminal and completely forgot about it - so I accidentally went ahead and suspended my laptop before it had finished. I resumed my laptop and noticed that yum hadn't finished 'cleaning up' the packages. Nevertheless, yum continued and the process finished. After an hour or so use of the internet (wirelessly), all of a sudden the wireless network disconnected, and NetworkManager crashed. I rebooted my computer only to find that NetworkManager now says that my 'firmware is missing' for my wireless card.

Ubuntu Networking :: Upgrade To 10.04 Broke R8169-based Wired Ethernet - Working Only At 10Mbps

May 1, 2010

After upgrading from karmic to lucid yesterday made my RTL 8111 -network card die. It's integrated on Intel D510mo mini-itx board.

dmesg:

Code:

After some googling I found out a lot of forumposts about the same problem from year 2007, but the troubles seem to disappear on the newer versions and seem to be back now? With those posts I managed to get the link up by using ethtool by setting autoneg off and setting speed to be 10mbps and half duplex. Any other speed/duplex combination fails.

One suggestion I found was to install r8168-driver from Realtek instead of the r8169. It didn't help, result was very much the same.

I booted to 9.10 live-cd and there the network worked as intended (100Mbps, I dont have a gigabit switch)

I really wouldn't like to fall back to 9.10, but my file server is not very usable with 10mbps.

Ubuntu Networking :: Wifi Signal Very Low

Jan 15, 2010

I was running windows vista 32 bit (NOW UBUNTU 9.10) on my custom built pc with a TP-LINK TL-WN353GD wireless pci card, before on vista my wifi signal strength would be in the low 70% range with a speed of 54 Mbps from a access point roughly 250 yards away, now with ubuntu 9.10 signal strength in the 15-20% range with a speed of 1 Mbps. My question is, what is the best way to overcome this wifi signal strength and speed problem, it is a noticable performance disadvatange easily seen on a website like ..... where as before videos would play 95% of the time without having to stop and catch up, would a different wireless pci card be a better choice than what I have, or is the problem in the software as in a driver incompatability or lack of correct driver, not sure how to remedy the problem.

Ubuntu Networking :: WiFi But No Internet?

Feb 17, 2010

I am new to Ubuntu, but because of my familiarity with Vista's Command Prompt, I was able to adapt easily.But there was a problem. My WiFi card didn't work. As it turned out, I was missing drivers.So I plugged into my dad's Gigabit Ethernet port and got ndiswrapper.That worked well, and my wireless card is working. The problem is that I can access the network in my house, but not the Internet. Everybody else (running Windows) can access the Internet wirelessly. But I have to steal my dad's wired work line. Is there any way to solve this? info about my computer, here it is:

OS: Ubuntu 9.10 Karmic Koala
Computer: (Laptop) Dell Vostro 1000
Wireless card: Dell 1390 wireless
Router: Netgear... some model or another
