Welcome to LQ,
Firstly, it's normally considered rude to ask for people to send you solutions by email - others on the forums can't see the responses, so don't benefit. Plus, it's a bit of a spam magnet for you
Secondly, you're talking about two different problems. Next time, it would be better to post two threads; one about the graphics problems, and one about your networking problems.
That said, solutions... We will need a bit more information to help you. What make is your laptop, and more specifically, your wireless card? You will probably need to install drivers for it. What is your graphics problem? And what did you mean by

? Your question suggests there is a problem with how things appear, your idea suggests you want to do some image editing... Could you clarify please?
