Ubuntu Networking :: No Wireless After Unity Upgrade / Get That?
Apr 30, 2011
After upgrading from 10.10 I now have no wireless activity. Everything was great with 10.10 by the way. I have a dell inspiron 1520 with a Dell wireless 1390 card and broadcom 440x integrated controller.
I have seen other threads that are to complicated for me to follow, I would just love for my wireless to work and can follow basic instructions if anyone can help.
I just spent the last 6 days in Florida on business while the tornadoes ravaged my homeland in Alabama and turned alot of people on to Ubuntu. Everyone that walked past my laptop wanted to play with it and asked what it was.

I am writing this using the 2.6.31-17 generic kernel after rebooting and selecting NOT to use the 2.6.31-18 kernel which was just installed. The newer kernel would not recognize/activate my Atheros AR2418 wireless adapter and, when I connected to the ethernet and did updates, there were no hardware drivers available. I haven't needed proprietary drivers since I upgraded to 9.04 and 9.10 works fine with older kernel.

NOTE: My upgrade wasn't smooth. Now everything is extremely slow. However if I boot from the disc to try without installing, the connection problem is still there. There is an exclamation mark on the connection applet, right clicking shows that Enable Wireless is unchecked and unclickable. I've included outputs of common network commands which might prove to be useful.
Code:
[~] ifconfig
eth0 Link encap:Ethernet HWaddr 00:1e:33:60:f0:3c
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

I have a thinkpad using the iwl3945 driver (Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks).
This worked flawless until I upgraded to 10.04. Now after a while my connection drops. Syslog is appended.
May 10 20:16:04 gimli NetworkManager: <info> Activation (wlan0) starting connection 'Auto my-network'
May 10 20:16:04 gimli NetworkManager: <info> (wlan0): device state change: 3 -> 4 (reason 0)

I upgraded from 9.x to 10.10. Under 9.x my wireless usb dongle worked correctly. After upgrade it does not. I checked the dongle on another machine and it works correctly. I inserted a usb memory stick and the system found it as a drive correctly. I assume from this that both the dongle and usb port are ok. The wireless device is a D-Link G122 A2 which is on the supported list (it ran out of the box on 9.x). The link light did not even come on. So I installed ndiswrapper and the windows D-Link driver (note that this was not needed in 9.x). Now the link light comes on and the wireless router is found but the unit will still not connect.
The log file entries on dongle insertion are as follows:
It appears that the problem is with wlan0 not being ready. If this is the case how do I make it ready?

I have an out-of-the-box Belkin G wireless router. I also have a Linksys USB adapter on a particular box. When I run the Ubuntu 8.10 live CD on that box I can see the router's SSID, I supply the password, and all is fine. I think that rules out any problems with the router or the ISP.
When I run the Ubuntu 10.04 on that same box I can still see the SSID but when I try to connect to it the DHCP fails. Checking the system logs I see the DHCPDISCOVER entries but no corresponding DHCPOFFER responses. So this seems on the surface to be a DHCP problem. To get around this I tried to edit the connection to use manually supplied settings. On the 8.10 system I supplied:
Code:
IP=192.168.2.200,
Netmask=255.255.255.0
Gateway=192.168.2.1
DNS=192.168.2.1
and again all worked just fine. But when I supply the same values to the 10.04 system it does not work. Even attempts to ping the router (192.168.2.1) fail. So if this fails then perhaps the problem is more fundamental than DHCP? I have tried searching the net for quite a while and found a number of similar problems, but clear solutions seem to be lacking (or I haven't come across them). One common suggestion is to blacklist the ipv6 module. I tried that and it seemed to have no effect. Since this worked so well in 8.10 and doesn't work in 10.04.

I just updated my work laptop to Natty: perfect. My home server: perfect. My oldish home laptop: no more wireless. [I use wicd instead of Knetwork (or whatever it's called) because I want a permanent connection no matter the user]
I have a D-Link DWA-645. I get the whole stage: connecting, authenticating, etc... and bad password at the end. The password is correct (hasn't changed during upgrade). I also tried disabling WPA and it still won't connect. That's wlan2.
I also tried with an older PCMCIA card that _used_ to work on ubuntu 9, but stopped on version 10: a D-LinkDWL-G650. It doesn't even show up as wlan0 as it used to. I also tried with a USB-wifi DWL-G122 which has always worked on every version of Ubuntu [I don't normally use it because it's not practical on a laptop]. I see it as wlan1, but same thing: won't connect. Note that like with wlan2 I can scan for networks and see several around. For instance:
Code:
$ iwconfig
IEEE 802.11bg
ESSID: off/any
Mode: managed
Access point: not associated
Tx power: 20 dBm
Retry long limit: 7
[Code]...
[Edit]
Some more info: the access point works fine, I can connect with another device. The driver in use by Ubuntu is ath9k. Using KnetworkManager instead of wicd doesn't change anything.

I had Ubuntu 10.10 installed on my main computer. Having been trying out 11.04 for quite awhile, I decided to install it on my main computer after it was officially released. I did this via an upgrade. Problem is now that I'm not getting any options for unity 3D. On the log on screen i have an option for unity 2D and unity, however both are unity 2D. My computer has a built in graphics card, nothing amazing, but i have happily used compiz effects on it previous to this.
My graphics card is up to it so why is the unity session falling back to unity 2D? Another problem that I'm having is that i cannot get the launcher in unity 2D to move out of the way. I even installed a programme called 2D Desktop Setting to try to fix this problem but selecting the various options to show, hide, autohide, etc have no effect at all and it's really frustrating having the launcher covering up the left side of my screen.

I am having 10.10-,automatic log on.I want to upgrade to 11.04 without Unity as my hardware does not support it.I do not want the option to modify 11.04 after its installation but want to avoid Unity direct at the time of upgrade from 10.10.

I ran update-manager earlier today and when I next booted I was told I had insufficient hardware to run unity -- despite it running just fine before the update. Now every time I boot I don't get the message, but it still won't run unity.I have tried downgrading them by forcing versions in synaptic but I keeps on wanting to remove large numbers of other packages that depend on them.

I am a competent Linux user for a little over a couple years now, having run several versions of Fedora, Mint, Xubuntu, and others for about a month before settling on The Ubuntu Netbook Remix when it was version 9.10. Loved it. Used it as long as I could until I was informed that my version could no longer be supported. So I went to 10.04, and used that for a while... but didn't know at the time that I could switch between desktop environments... and it stuck me with the classic view. This was OK, but I'm using an Asus Netbook (1005PE)... And sorely missed the Netbook UI.
So I went and upgraded to Version 10.10. Mutter was a MESS. It was so choppy and unpredictable I only used it a few times before getting frustrated and switching back to the classic compiz UI.
But I still like the idea behind the UI, so I downloaded and ran the 11.04 version live off a flash drive (I LOVE that ability!)... and Unity worked fine. I actually liked it. So I upgraded to version 11 and booted up to find that Unity is not visible.
I can log in to the classic view just fine... But logging in under Unity will display the background and provide seemingly full functionality (If I know where to click!), but I can't actually see the UI until I click an invisible button. Once I do that, the program or menu alone becomes visible, and works fine. I just can't see Unity.

As an introduction to the problem I'm having: For a long time, I've been on 9.04 and my wireless worked quite happily. Then when I upgraded to 9.10, to my despair I found that my laptop no longer detects my wireless driver! Before I go on, I should also say I'm rather inexperienced with Ubuntu in general, despite having used it for quite some time.
Anyway, onto the informational part: I'm using a Compaq Presario CQ40. According to lspci, my wireless network card details are as follows:
Code:
03:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
lsusb shows the following:
Code:
Bus 003 Device 002: ID 03f0:171d Hewlett-Packard Wireless (Bluetooth + WLAN) Interface [Integrated Module]

This should be easy for the Ubuntu Gods to sort out:
I have a Sabrent USB 802.11N adapter. (I am using 64-bit Ubuntu in all below)
I plug it into a 9.04 box and it works fine. Plug it into a 9.10 box. Network manager sees it and can attach to the network, but has 0% signal strength, no internet.
Rebuild the 9.04 box with a fresh install to 9.10. 0% signal, no internet. Try 10.04 Alpha 2, 0% signal strength, no internet.
Rebuild same box down to 9.04. Works perfectly. 100% signal strength. I do all updates and then the upgrade to 9.10 using the USB. Everything works fine until the reboot. Then, USB connects, but 0% signal strength, no internet. Oh! ifconfig says the wlan0 interface is up, but it has a random ip address.
I don't mind using 9.04 because for the forseeable future, the box is just going to count aliens for Seti, but my wife wants it off the counter and I would like to upgrade someday.

I recently upgraded Ubuntu 9.10 to 10.04 and my wireless stopped working. It can detect that there are networks around, what their signal strength is, and then try to connect to one, but it just keeps connecting. After around 5 minutes, this stops and nm-applet says no network connection.
After I try to connect, dmesg is spammed with hundreds of the same message. I can not post these here, as I am writing from a different computer and I have no internet access from my main computer.Also, there is nothing in interfaces.conf other than lo. For some reason, my card is referred to as both wlan0 and wmaster0, with this changing depending upon where I look.Most interesting of all is that, even after I reinstalled 9.10, wireless is still broken, even though it wasn't before. It also used to work under liveCD.

I upgraded to Ubuntu 10.4 on my Dell Inspiron 6400 yesterday (32-bit). Everything was running great, but when I turned it on today my wireless adapter is no longer working and the hardware switch doesn't do anything. It's working in Windows fine so it can't be the hardware.Here is some information:
Adapater name: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Code:
iwconfig:
wlan0 IEEE 802.11abg ESSID:off/any[code]....
Restarting the network with 'sudo /etc/init.d/networking restart' didn't work.I've tried Ubuntu several times before but usually there is one small issue which makes me go back to Windows. I love 10.4 so I hope I can get this working so I can stay on Ubuntu!

Since I've upgraded to Kubuntu 10.10 I've lost my wireless internet. In Windows 7 everything's fine, but in Kubuntu wicd keeps giving a "Unable to get IP address message".
Here's some output:

What has changed to the wireless function and possibly the use of the ndiswrapper in 11.04.
I originally install ubuntu 9.10 and immediately upgraded to 10.04. I have just now decided to upgrade to 10.10 and then to 11.04. Everything went ok and all still worked fine up until the upgrade to 11.04.
I've checked my settings and they are fine. The power light is still on my wireless card but no connection?

Ever since I upgraded to the new Ubuntu, I have been having problem with wireless. In the "Hardware Drivers" I come up with 2 drivers:
1) Boadcom B43 wireless driver
2) Broadcon STA wireless driver
I activated the first one, but latter noticed that the wireless was not working, so I tried installing the second and it returned this message:

So I unactivated the first and then it disappeared leaving me with the second, and its error message.

What should I do now?

Like many others it seems, my wireless has stopped working since a recent upgrade The answer does not lie in analysis of logs, settings etc. but surely with those who did it - they should provide a fix. I cannot believe everyone expects each individual users to go into their own analysis of why this is no longer working as it is clearly widespread. I have been using Ubuntu for 18 months without this problem on the same dual-boot laptop, and it still works on Windows as before, only Ubuntu 10.4 has recently stopped my network card from working.
I need to know when this will be fixed. I have been embarrassed by promoting Ubuntu to many colleagues who now also cannot work at home on their wireless networks. Seriously disillusioned I may start looking for a more stable alternative to Windows.

I have an Asus K60 laptop with the Athlon chipset. I had wireless working just fine under Lucid. But after upgrading to Meerkat, I can't get my password to be recognized. The router connection is seen without any difficulty, but the WPA password is rejected every time. I've rechecked it, of course, and also checked that it works in the Windows partition on the same machine. I'm using wicd and madwifi, recompiled for the -35 kernel. Here's the relevant output of lspci:Quote:
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
03:00.0 Ethernet controller: Atheros Communications AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0)

today i installed ubuntu 10.10 on my hp mini 210 netbook. previously i had ubuntu netbook remix running and had no problem accessing the internet both wired and wireless; however, since installing 10.10 i have been searching for a solution for the last six hours but have been unable to get either to work.
as far as hardware is concerned i have a broadband bcm4313 802.11 network controller and am running through a linksys router which i know to be working because i have 4 other computers connected to it all with internet access. i checked ifconfig and a lo conection was listed but no eth0. i also tried downloading a broadband tar.gz driver but dont have any packages to build it and cant get any since the computer has no internet. i assume wired is easiest to setup so lets start there even though i use wireless 90% of the time. im new to linux so please dont expect me to know any terminal commands.

I have upgraded Intel Core2 Duo (Macbook Pro laptop) system to Fedora 15. I believe I have the proper firmware driver installed for my wireless network adapter. In Gnome I can click on the network status icon and select my wireless network, however nothing happens after that. Fedora does not prompt for my wireless network password, and no network connectivity is established. What can I do that would get my system to connect to the wireless network?

I am running Maverick Meerkat now, and will think about upgrading to Natty next week. I have a question--I run GNOME as the environment now, and if I do upgrade, will Natty replace it with UNITY?

Upgrade of kubuntu to 11.04 from 10.10 using kpackagekit appeared okay, as did the reboot and login from the new panel. Then, instead of seeing my custom background and plasma desktop all I see is the color wash of the Unity background. There is a right button menu in this desktop with a Create Launcher option that allows me to make launchers for konsole, firefox, and ksystemlog. Windows come up, but with Unity window decorations. Sure enough unity-window-decorator is running, but there is no plasma. System logs don't reveal anything obvious that failed. There is a kdm process running and kdeinit4 appears to have tried to start klauncher and kde4, but they are not actually running.It seems like somehow GNOME and Unity have somehow collided with the KDE environment.

When I first did the upgrade to Natty, no desktop at all would start. I could only get a text terminal login prompt. Log showed a segfault in fglrx module: "firegl_SetSuspendResumeState" I found instructions to remove the fglrx module and install the default ATI driver. Now I get a graphical login screen. But I must only login with "Ubuntu Classic (No effects)" in order to get a desktop. If I select Unity or Ubuntu Classic, I never get taskbars or menus and can't run any apps. So Natty Narwahl is a big step backwards for me. What is the relevant information to provide? The display driver is listed as RV710 [Radeon HD 4550] from ATI Technologies Inc.

I was running 10.10 with an Nvidia Quadro FX1500 and was able to get the effects (Compiz) working after following the manual driver install (found here) and editing my xorg.conf file. After this upgrade, Xserver (my desktop) wouldn't even launch. It just kept going into a terminal for log in. Not bad - better than not being to do anything at all. I removed all my nvidia drivers
Code:
sudo apt-get remove --purge nvidia-*
and then created a new xorg.conf file (and later moved to /etc/X11) using
Code:
Xorg -configure
That now allows me to log in to my desktop. However - no Unity. I've read that some people have had luck with the Nvidia 173 drivers, but not here. When I downloaded the current nvidia driver for my card (Quadro FX 1500) from nvidia, and went to install it manually using (from the directory where the download is)
Code:
sudo sh NVIDIA-Linux-x86-270.41.06.run
Eventually, it errors out with this: The compiler used to compile the kernel (gcc4.4) does not exactly match the current compiler (gcc4.5). For the record, I can't boot from a thumb drive ("boot error") or CD (both were created and tested on a Windows 7 machine.)

I recently upgraded to Ubuntu 11.04. Most of the upgrade went well except for one package (mpd). Ubuntu rebooted and went into a sexy-ish minimal grub. I launched Ubuntu, everything went fine. The only thing I can't seem to get working is Unity/Gnome. When I log on with kdm and choose 'default' or Ubuntu Classic, everything loads fine except for the taskbar/whatever interface. (I usually run wmfs instead of kde/gnome and I'm not sure which interface is currently installed right now. I have both kubuntu-desktop and ubuntu. )
I can still, however, right click and see my desktop/desktop icons. The only thing that does not load is the gnome/unity interface itself. I need it to manage my fonts to fix my wmfs fonts that got screwed up. (I'm using a bitmap font and it doesn't work unless I activate whatever settings I have to activate. )
I am not home right now and this was written on a phone. I apologize if this whole post seems confusing/total blabber. edit: Ubuntu Classic works fine, but Ubuntu/Default does not automatically launc the Unity interface.

I installed Ubuntu two ways, both by partitioning the hard drive and installing Ubuntu in its own partition, and also where the "run within Windows" option was available. I then upgraded both to Ubuntu 11.04. When I start Ubuntu in the "own partition" installation, Unity runs without complaint. When I start Ubuntu in the "run within Windows" installation, Unity baulks, giving an error message that I don't have some (unspecified) of the hardware it needs to run, and I am kicked back to the classic Ubuntu control screen setup. Obviously the two ways to install Ubuntu don't result in it having the same behavior. Alternately, since the version installed to "run within Windows" seems to do no such thing, and also gobbled up almost all the free space in my Windows-7 partition without prior warning, any clue how to uninstall that version cleanly?
