Ubuntu Networking :: Unable To Use Wireless After 8.10 To 10.04 Upgrade
Nov 28, 2010
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.

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?

On my opensuse 11.1 system. I used my tp-link tl-wn321g usb wireless adapter to access the internet. It runs on rt2501 chipset and I used the serial monkey rt73 driver from here.
[URL]
What I did was I installed the kernel-headers, kernel source, gcc and make. And then I cd to the module directory and did
Code:
make
make install
modprobe rt73
[Code].....
I installed "ralink-firmware-1.1-1.5.noarch.rpm" from Software.openSUSE.org. I tried "make" again, but still the same error return.

The upgrade went well, but I could no longer use my wireless adapter. I tried installing the driver again but when I tried to run "make", it says
Code:
make: *** /lib/modules/2.6.31.8-0.1-pae/build: No such file or directory. Stop.
rt73.ko failed to build!
make: *** [module] Error 1
I've checked that kernel-headers, kernel-source, gcc and make are all installed.
I installed "ralink-firmware-1.1-1.5.noarch.rpm" from Software.openSUSE.org. I tried "make" again, but still the same error return.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

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?

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 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.

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!

After I upgraded from 8.10 (or 8.4, I'm not sure), the wireless signal is very weak:
Code:
~$ sudo iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:"mina"

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:

wlan0: associate with **:**:**:**:**:** (try 1)
wlan0: RX AssocResp from **:**:**:**:**:** (capab=0x411 status=0 aid=2)

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 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.

Since I upgrade to Ubuntu 10.04 my wireless connection is very unstable. I install the needed wireless drivers from 'Hardware Drivers' (Broadcom STA wireless driver) and I got wireless connection, but it randomly disconnect, and also connection is very slow.
I think that the problem are the drivers which are not very compatible with this version of Ubuntu, which means we need to wait for update? I have HP ProBook 4510s laptop, Intel PRO/Wireless 5100 AGN network card & Gembird NSW-R2 router. I'm only having this problem on Ubuntu 10.04, on other OS's the internet is fine.

My wireless connection ran without issue when I ran Ubuntu 9.x on a windows dual boot loader. Liking Ubuntu, I wiped the system and installed a 10.10 with no dual boot. After the upgrade, my wireless connection is no longer reliable.
Wireless seems to stay connected when traffic volumes are low. As soon as any significant traffic is generated such as a download, torrent or video stream, the network disconnects. Disabling and re-enabling the connection at the GUI recovers the connection. Disconnect can be generated on demand.
If I can somehow roll back to the 9.x network setup I was running. Unclear to me (n00b) if the windows dual boot was impacting that setup or not.

Recently I have encountered Problems with my Wireless that I have not had before and I cannot fix. So I am asking for help.
6 month old Dell Insperion 1730 Laptop
Dual boot Karmic/Win 7
WUBI install.
No problems till about a week ago.A week ago I upgraded to Lucid and could not get the DVD drive to mount no matter what. The OS saw it but would not mount it...... uninstall and re -install Karmic.As soon as the patches are installed from the update manager, I lose my wireless completely. Wired connection still works.
I have tried different things from here and other sites. Basically I need to know how to enable my wireless card. There is no switch and key combinations (ALT+ F2) don't do anything. Connectivity in Win 7 is fine.
The Applet says wireless is disabled and so does the output from $sudo lshw -C network.It sees the interface but the network is disabled. lsmod shows the driver. iw list scan says does not support scanning. Newtwork is down.I know there is something in the updates that is messing the Intel WiFi Link 5100 up. On a fresh install all works till updated.
