Ubuntu Networking :: No More Wireless Upon Natty Upgrade?
May 8, 2011
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.

After upgrading my laptop from 10.10 to 11.04 I can no longer connect to my home wi-fi. It was working flawlessly for months before the upgrade. The network manager just keeps spinning and nothing happens.dmesg output just keeps showing this over & over again:

After being prompted by UpdateManager, I upgraded my Compaq Presario CQ71 from 10.10 to 11.04 yesterday. Most things seem fine, except that my wifi is disabled (it was working fine in 10.10).
Here are some details:

I have two laptops, both with broadcom drivers and in both it's working pretty well with my university network but I can't find my home network on the list (I can see my neighbours network). It was working perfectly before the upgrade, and of course, I can connect on windows to my home network.

Our Acer 5820T handles Natty nicely in all respects except for the wifi not working. It was fine under 10.10. It uses the Atheros ath9k driver ... details:

I have just upgrade to natty from maverick and my usb wifi dongle doesn't want to work. The usb wifi adapter i use is a Thonsom Speedtouch 121g. When using ubuntu 10.10 it work's fine after installing the package linux-firmware-nonfree, but after upgrading to natty it has stop working (the linux-firmware-nonfree package is installed [don't know if is the same version or an upgraded one]).
The network manager doesn't display available wifi nets. The output for lsusb is:
Bus 001 Device 004: ID 06b9:0121 Alcatel Telecom SpeedTouch 121g Wireless Dongle

I'm running Linux 11.04 and my wireless network was working just fine until today. I cannot connect to WiFi - it acts as if the device wasn't there. The hardware switch led isn't working. No matter how much clicking on it, it won't work.
iwconfig:
Quote:
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bgn ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=14 dBm

How do you set wireless speed in natty? I've tried
Code:
sudo iwconfig wlan0 rate 54M
but nothing happens. I've tried this with wireless enabled and disabled (using network-manager), with and without the module loaded (ath9k) and using the solution provided in some forums (adding the command in /etc/rc.local and in a script in /etc/network/if-up.d) but to no avail... link speed always shows up as 65M.

I recently upgraded my Zepto laptop to Natty (11.04), and unfortunately the wifi no longer worked. I have a WPA net, and the combination with a Ralink chip seems unfortunate - judging from the number of internet posts.After browsing loads of threads on the 'net I think I have found a solution for 11.04 - it will work out of the box in 11.10 !
1) Add "blacklist rt2800pci" to /etc/modprobe.d/blacklist.conf
I think this makes the wifi stuff work as I can then do "iwlist wlan0 scan" and get reasonable output. But there is no integration with the Network Manager. So I have also done this (again, with inspiration from a few threads):
2) Edit /etc/NetworkManager/NetworkManager.conf - change the "managed=false" under "[ifupdown]" to "managed=true".
You may have to do a "service network-manager restart", restart or similar to get it going.It also seems I can suspend and get a wifi net connection upon wakeup.

I recently upgraded from Maverick Meerkat to (classic) Natty Narwhal Ubuntu Linux. I am running on a Toshiba Satellite A665 (Intel i7). I use a wireless internet connection. Under Maverick, I had no issues. Under the update, I am finding that occasionally things stop working: The indicator Applet looks fine, but from a terminal, I find that I am no longer able to ping my own router (less than 10 feet away.) This behavior occurs after working fine for a few hours. I am unsure if anything in particular triggers it (I will report back if I determine a particular cause). I have a few other computers (2 running Windows, and the other Maverick Meerkat) -- and they are unaffected. Turning wireless off and on resolves the issue for me on Natty. Rebooting also works. Here's some hopefully relevant technical details about my system:
Code:
~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

I'm using an Atheros ath9k wireless card that has been pretty stable since Ubuntu 9.04. I did a clean install of Natty and ever since my wireless connection has been pretty unstable.
It doesn't actually disconnects but I lose all connectivity. The wifi card continues loaded with a static IP Address assigned to it but I cannot connect to anything. The only way to fix it is restating the network manager and I have to do it at least a couple of times every day.
I tried to whitelist ath_pci on /etc/modprobe.d/blacklist-ath_pci.conf but the problem still persists. Also yesterday I enabled the ubuntu backports on my software sources but so far no kernel updates.
Here are some of the messages filling up the logs:
I added all this info to this bug as well: [url]

just installed Ubuntu 11.04 x64 on my Samsung R580 and cannot get the wireless to work/detect any networks around me (it looks like its on though at least as far as the indicator lights show on the notebook). I tried search around a bit and wasen't able to find anything...

I started playing with Natty Narwhal (11.04) last week. I have a Toshiba Portege R700 laptop with 4GB of memory. Firstly, let me say that when I run 11.04 on the bare metal laptop (installed via WUBI) it appears to work flawlessly. That is, both the ethernet (hard wired) network and the wifi network work just fine.The networking problem occurs when I try to run 11.04 as a (Type 2) VM in VMWare workstation with an underlying o/s of Windows 7 Enterprise.
In this mode, the ethernet network works fine but the wireless network does not work. The o/s does not even see the wireless card. I have downloaded and installed about 216 MB of updates from the update center to no avail. I have "bridged" the VMWare "virtual switch" across to both the ethernet port and the wireless port (see below):Basically, it appears that the interface is not being presented to the VM.Also, of interest, Unity which works fine on the bare metal install does not run on the Ubuntu 11.04 VM.

I've been happily using this lappie with LTS but wanted to try out 11.04. It looks great but wireless has been an issue:
1. No wireless during install
2. Had to manually blacklist the rt2860pci etc modules
3. Wireless still not resuming after suspend
05:00.0 Network controller: Ralink corp. RT2860
Subsystem: Ralink corp. Device 2790
Physical Slot: 0-2
Flags: bus master, fast devsel, latency 0, IRQ 18
[code]...
The latter manual mod improved things slightly but still no cigar

I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?

I'm on Natty since yesterday but I started the day before. My first impression was great. I now had an option top upgrade from 10.10 and not loose my data! So I did. It all went fine until the point where The Upgrade tries to restore my applications. It failed and returned the message:
unbalanced group option, expect badness.
And that was it! And I would have been waiting a very long time if I wasn't looking the details of what's going on because from here and after a 3rd try, I went to sleep online to find out I was still expecting badness the next day. I did a hard reboot and tried login in. I reached the login screen with success but could never login. I was using the encryption options which it seems comes after the restoration of application.
The symptoms are those of a wrong password. I finally did a clean install and restored my data from my backups (wouldn't try something new without a backup). Otherwise, I like Unity. I see a few things that needs polishing here and there but I don't mind using it. I think that voices from people liking it need to be heard as well because they usually don't have a reason to complain and it then looks like every body think Unity is not good.

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

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.

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.

Since upgrading my former Karmic/Lucid/Maverick laptop to the Natty beta recently, I've been unable to change anything about my desktop background. Each time I reboot, the background is a different solid color, but I can't change the color nor set a wallpaper image. Here's what I've tried;
- "Appearance Preferences" -> "Background"
- the compiz wallpaper plugin
- gconftool-2/gconf-editor
- xsetroot

obviously natty is flawed. I upgraded as an option in ubuntu studio's update manager. not sure if studio was ment to be upgraded to natty but it was in the manager, as studio is still 10.10 maverick. regardless the results have been disastrous. i am running into problem after problem as apparently many users are.
i had recently done a fresh install of ubuntu studio maverick which seemed perfect. as i was still setting up and restoring until i noticed the option for natty. so while i'm still at it i think i'm going to reinstall 10.10 this is the first imperfect ubuntu upgrade i've experienced but linux still rules.

When I try to upgrade from 10.04 to 11.04 I always get this error:
Code: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
If I run sudo apt-get dist-upgrade, I get:
Code:

Apparently there's nothing wrong in apt.log, but i cannot upgrade and i don't know how to fix it. Any clue?

When upgrading from 10.10 on my machine, Natty set the default boot image as 2.6.38-8-generic-pae, which didn't boot (stuck at the start image: ubuntu logo with 5 red circles). I can boot to 2.6.38-8-generic if I go into previous versions. Everything, best I can tell, works fine after doing this. I'm a complete idiot when it comes to Ubuntu. How can I uninstall/remove the 2.6.38-8-generic-pae image since it clearly doesn't work? Why would it have set this as my default image in GRUB? How can I set the normal image as default in GRUB?
