Network connection problems
 

I recently got Ubuntu using Linux Pendrive, and all features are perfect, except for one small thing, I can't connect to the internet. In reference to the replies I will probably get I did go into the network dialog box, type in all the information and my network isn't secured (I live in the country 400 yards away from the road.) So it should connect. Long story short, I had my genius computer brothers come over and still it won't work. Both my brothers tried a whole bunch of stuff in the terminal and MC but I still wouldn't work. I am on a Dell Inspiron 1520. What I believe it is, is that Ubuntu doesn't know that the network driver exists. Thanks for looking into this for me!

Welcome to LinuxQuestions.

Do you know what stuff your brothers tried?

There are many threads that show how to install the latest drivers for the broadcom wireless chipsets.

is the problem at wired and/or wireless connection?

phisical connection/old driver stuff
 

There is no connection problem due to the fact that I am using Windows installed on my C: drive and wireless is working fine. As to the commands my brothers performed in the Terminal I am not sure. I will send them an Email asking them what it was.

I believe I have found my problem thanks to the the Ubuntu forum. I appreciate it and will see when I try it. I will keep you posted. Thanks for the fast feedback!

Ok...I tried this stuff...and it didn't work...

when i asked

i was not trying to figure out if the connection from a windows machine is ok or not.

what i was trying to figure out was if you were able to connect to your network with a wired connection from Ubuntu?

if it is so then you problem will not be named as Network connection problem but Wireless Network connection problem .

and this is most probably due to a firmware problem.

Oh, sorry, misunderstood. I can't connect in Ubuntu. Wireless or wired. So...yeah...

Post the output of:
This will list all of the devices on your computer, including your ethernet and wireless devices.
Also post the output of:
This will list all of the drivers that are in use on your system.
This way we can determine if you have the proper drivers installed on your system for your internet connection to work.

You should try to connect via a wired connection first if you can, since this has fewer variables. Then once you are online with a wired connection you can work on the wireless if that is what you prefer to use.

Thanks Tommcd, I did what you told me and it said that the wired driver was there but the wireless one was missing and it told me the link right to download it. I plugged in with an Ethernet cable and installed it and wireless works great! Thanks for the help everybody!!

Ok...I did some research and I found the problem and soulution...
-Open terminal type in
sudo apt-get update
sudo apt-get install bcmwl-kernel-source

and that did it for me, it connected with no problem...
