help please
 

ok sorry ill re-explain all i need 2 know is how 2 get onto the internet i have a modem and a ETHERNET network card it is from D-link and no it has no antennas its a D-link DFE-530TX+ i dont know about the modem because it was preinstalled, sorry about the first post i was in a panic

First of all, not a good subject definition. Secondly, do you mean an ethernet card? As in no antennae, direct connection? Also, you need to supply manufacturer and model number.

ok well I found a driver for the mentions ethernet card but its written in c++ and i dont know how to install it on the ubuntu system i transferred it with a flash drive

There should be a README file or an INSTALL file included with the driver you downloaded. Check that for instructions.

All drivers and most other programs that are Linux specific are written in C (or sometimes C++ if they are third party maybe) and so they need to be compiled into binary programs and installed. 99.8% of the time, there's a file containing instructions on how to build and install it.
I don't use Ubuntu, but typically, after extracting the archive containing the C code, you go into the folder where the code is, in a console and type 'make' and when that is done, type 'make install'. If there are absolutely no instructions on its usage, personally I wouldn't install it.

After successfully building and installing the driver, you may need to use the 'modprobe' command to insert (activate) the driver.
