Hi, and welcome to LQ ...
As for the question:
a statement like
If someone could tell me exactly what to do with my internet. It is very slow on LInux only
doesn't really give any indication as to what your
problem might be.
If you said something like:
In Windows I can download at 1.5MB/s, in Linux
downloads trickle along at 20K/s, there would be
a fair indication as to whether there a) is an actual
problem, and b) a hint as to where the problem
may lie ...
