After updating/upgrading, no wireless is possible.

Postby mauriciocamara on Tue Mar 15, 2011 2:52 pm

Hello, gentleman,

First of all, congratulations for The Team for developing such this great LMDE distro. I've been using it for the last months, and is the only distro installed on my computer.

I updated/upgraded the system today, as I usually do every week, with the command

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

And now I am unable to use wi-fi connections.

Clicking with the right mouse button on the NetworkManager applet shows me that "Enable Wireless" is disabled. I can't enable it anymore, regardless of clicking the option to enable it.

"Enable wireless" was always off everytime I logged on LMDE; everytime I turned it on and used wireless internet flawlessly.

Did i do anything wrong on my update this time? Please help me, if you can.

My laptop is an Acer TM8172T-3519, 2GB DDR3 Memory, 250 GB HDD, Intel Core i3-330UM processor, Intel HD Graphics.

Please let me know if I can provide any forther information (commandline, etc)

Thank you very much for reading this post.

You've never had to install a Proprietary Driver in the past?

I'm not sure this is the problem, but it may be a possibility. Possible it changed the path to the Driver already installed.

You might also want to avoid the kernel upgrades, usually caused by that last command (even though the current (before a reboot) kernel should still be available to select))
    Unfortunately other application updates may also happen, causing you some issues..
Code: Select all
sudo apt-get dist-upgrade
--that last command


Also, you can check with the wireless tools or ifconfig to see if the wireless card is running, and then either lspci or lsusb (if it was a USB wireless card)
https://help.ubuntu.com/community/WifiDocs/WiFiHowTo
    Using the command Line
    If you can browse the web your card is set up and working. If not we can try doing it another way. Start a Terminal Window and type
--see that section in the link to check status of wireless..
    If you can't connect to the internet nor have already installed the wirless-tools, iy will be more difficult..
If you still have the Linux Mint CD, you can usually run the connection from that (run from CD, boot the iso CD) and mount your hard drive to get an update, such as getting the wireless tools onto your hard drive

And as always with a long document, initially scan for the sections that you need (pertaining to what you want to check!)
