both wired and wireless internet connection not working

Do you have any other way to access the Internet from the machine?

Have you tried to open System Settings > Software Sources > Additional Drivers tab? If you`re lucky, you can choose which (proprietary) driver to use!

I had a look at the site you linked to:

http://www.wintecind.com/support_center/support/Documents/Linux%20Driver.rar

Try that - Good luck! ;)

I downloaded this driver package and it comes with a lot of files and no installation program. I am not sure where to go from here.

FYI

The tech support at wintec said:

This item is compatible with Linux, the driver works with a specific version of Linux.

    2.6 kernel: Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006,

    SUSE 9.3/10.1/10.2, Gentoo 3.1, Ubuntu 7.10/8.04, etc.

    2.4 kernel: Redhat 9.0/9.1

I am not sure what all that means or if the driver is compatible or not. I know how to install windows drivers on XP but I'm clueless with ubuntu.

To answer your first question, no.
Maybe I could tether my cell phone but data is limited. Also not sure if ubuntu would work with tethering.

Ok, I had a look at the package now.

Youre supposed to run these commands in order:
make
sudo make install

Then reboot.

However, it won`t compile on my computer. (make[1]: *** No rule to make target `Driver/HAL/rtl8192'. Stop.)

This is not the first time I`ve seen official drivers for Linux which are practically unusable for most end-users, just so they can put a pretty penguin sticker on the packaging. I`ll see if I can get it to work, so I can give you a step by step guide.

Hi ,
can you please follow the troubleshooting procedure and provide here some useful info ?

You must have the Wireless adapter plugged in.

Thanks

What is the output of:

sudo lshw -C display; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

Thanks

The trouble shooting procedure came to a point where it wanted me to access the internet, (which I obviously can not do).

This is the output requested by actionparsnip

sudo lshw -C display

I'm confused.

Run the command and give the output please

God I'm so tired. The command is:

sudo lshw -C network

As your issue is network based :).

I emailed realtek. Maybe they know what to do...

No response from realtek. Thanks for the links but I'm not sure what to do. Most of it is beyond my know-how.
I give up on linux again.

I've found that logging on to my router and pinging my Linux 12.04 system using the connectivity test has helped me. Often after a recoot I've lost internet connection, not the LAN, just the internet access. When I use another computer on my home LAN, logon to my router and test connectivity to the Linux machine, the internet access returns. I don't know why this works, but it does. Good luck!
