Linux Ubuntu problem

Can you connect via wire direct to the router?

See if the information in this thread helps

There is also info here: http://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers but I think the link from bwanshoom is probably better.

Which version are you using? I would first try choosing advanced options on the boot screen, then the previous kernel.

I'm not that familiar with Ubuntu. I believe some members are actively using it?

Just stood up CentOS on a surplus Xeon workstation as local lamp stack dev box last week, though it's based on Red Hat Linux Enterprise, so don't know how similar it is?

Worse case if unable to roll back, you could reformat the drive for clean re-install of Ubuntu? Use a free self booting utility such as GParted. Make sure to save any files first.

You could also try just running network manager- you should be able to search and find it. If not, try opening a terminal and running either:
nm-applet

or

nm-connection-editor

should open the network manager.

Thank you all for the suggestions. I am on the road right now but will try them out on my laptop when I get home in a few days. I'll update the thread if any work or not.

Got home and tried all of the suggestions given. Not much luck!:(

I am running Ubuntu 14.04 LTS. It is on a Toshiba L305 64 bit, running Windows 7 Home Edition with Ubuntu as an optional boot.
Using Windows right now to get online.

Chris:
I tried both of your suggestions and could not decipher the results. Here is what came up on the screen. Perhaps you can explain them?

Thank you very much for reading that long quote and for the help.

For kicks try:
sudo service network-manager start
and see what happens:)

Thanks Chris and all the others who made suggestions. I have given up and used my system restore disks to put the computer back to factory original. That went fine and now am installing Windows 7. t Then will try my backup that I made some time ago. It should have most of my programs and settings on it. If not, I have a lot of work to do yet installing all the programs. I am not going to install all of them though. There were a lot on there that I never used.

Just waiting now for Windows 7 to finish installing and then I can get to work again. Has been a long day on the computer! I am going to keep this little netbook that I am using now on Ubuntu, but not going to put it on the laptop again.
Thanks again for all the help. :)
