Ubuntu

Network Manager working, but no wireless in menu

Asked by Theodore Lewis Cook

          I'm using Ubuntu 15.04, on an absolutely fresh installation. It's installed to a 500 GB external usb hard drive. In the panel, the network manager icon appears, with options for VPN and wired connection, but nothing related to wireless connection. I was able to connect using the liveusb I used for the installation, on the same computer, and with the same wireless network I was attempting to connect to on the external hdd. I know what I am doing as far as installing linux on my hdd, and I can't understand what I could've done wrong. I successfully connected to this network on this computer with this hdd using Opensuse, Manjaro, Antergos, Arch, and all previous versions of Ubuntu from 12.04 to present. Vivid Vervet is proving problematic thus far.
          Here is the output of "lspci | grep Network":

          00:19.0 Ethernet controller: Intel Corporation 82566MM Gigabit Network Connection (rev 03)
          10:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

         Also, if you recommend packages I need to install, please be sure you know what you're talking about, as I have to boot into the liveusb to download the .debs and then reboot into the hdd with each attempt. Thank you for your help.

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable) and apply all updates.

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1

In the Ubuntu Terminal console , make sure that unlimited scrolling is enabled:

click on Edit > Profiles > "Default" profile > Scrolling. Choose "Unlimited" as scrolling option. Click Close and Close again.

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface (default graphical user interface in Ubuntu), use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

So the methods in Unity are:

Press CTRL-ALT-T key combination.

Dash > Search for Terminal

Dash > More Apps > 'See More Results' > Terminal

Dash > More Apps > Accessories > Terminal

Step 2

Please copy-paste the following diagnostic command from the

https://help.ubuntu.com/community/WirelessTroubleshootingProcedure

website using a web browser (like Google Chromium or Mozilla Firefox) into the Linux Terminal. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE diagnostic command below from the web browser into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the diagnostic command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install usbutils pciutils hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | grep -Ei 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nnk | grep -iA2 net; lsusb; nmcli nm status; sudo lshw -short; uname -a; sudo updatedb; dmesg | grep -E '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|RTL|rt2|RT2|rt3|RT3|rt5|RT5|rt6|RT6|rt7|RT7|usb|witch|wl';sudo dmidecode|grep -E 'anufact|roduct|erial|elease'; iwconfig; grep -E '80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl' /etc/modprobe.d/*; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|grep -E 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; ls -lia /boot; grep tmpfs /etc/fstab; ubuntu-support-status; sudo update-pciids; sudo update-usbids; sudo lsmod

Step 3

Please do NOT attempt to send any attachment(s). Please copy/paste the full terminal output at this location:

https://answers.launchpad.net/ubuntu/+question/268377

Please send the output from your Ubuntu install, NOT from a LiveUSB session....

The troubleshooters at Launchpad need to see the full Terminal output from running the above diagnostic command.

Step 4

Please also specify the exact model and make of your PC (if known) when creating the new Launchpad question.

Please also specify the name of the wireless access point that you are trying to connect to (not the model/make of your router).
