http://ubuntuforums.org – Hi - am having wireless connection probs. Have the trawled this site and others for help but can't figure it out. Probably doing something stupid... I have a wireless router running wpa2 which is being used fine by a variety of devices. I have tried 2 machines now running ubuntu 12 (and tried another simmilar distro) and I can't connect. Wired connection is fine. It detects the wireless network but wont establish a connection. I've tried disabling security, picking different wireless frequencies. any help gratefully received. here's the syslog with networkmanager messages: (Hardware)

Stories similar to [ubuntu] wireless connection from ubuntu

I just installed Ubuntu on my laptop yesterday and it connected to the wireless fine. Then I took it to school, put it on their wired connection, downloaded some stuff, and now the wireless doesn't work.

At first it would detect networks, but not connect. I restarted it and now it can connect, but it acts like it doesn't have internet in the browser. Wired connection still works fine on it.

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.

Iam a newbie to Ubuntu and linux ....

I had install Ubuntu 12.04.1 precise pangolin LTS last month

Had no problems with connectivity , both wired and wireless connections worked ... until recently I happened to install and upgrade the Ubuntu repositories... after restart the wired connection works but my wireless connection is lost completely ... I use a wireless router at home ..

I tried to install a recent kernal update that got hung up and wouldn't finish so I aborted the update. After that I could no longer use $sudo modprobe b43 to initiate my wireless connection. My strategy is to establish a wired connection, make sure all updates could be installed, and then try to establish the wireless connection again. However, I cannot establish a wired connection.

Hello there. Just now started working with crunchbang and am attempting to establish a wirless connection with my home router. its a netgear wgr614v10.Having no issue with wired connection, but cant manage to get the wireless to work. Ive got the SSID, MAC, MTU set to auto, wpa/wpa2 pass set up to what it is, ipv4 is being ignored.... nothing.

Hello there,

I am pretty new to Linux, just installed 10.04 version. I really like it, but I have a serious problem with my wireless connection.

I have a recently-upgraded UNR (12.04) running on my netbook, and I just built a computer with Ubuntu 12.10.

After upgrading 12.04 LTS, my wired connection works but no wireless connection found.

So I installed Ubuntu 10.10 and clicked on the wireless button in the top right corner and it detects my wireless just fine. But when I click on the name of my wireless network Ubuntu asks for my password and encryption, the four it lets me choose from are not the ones I have my router set to.
