Took ubuntu hard drive out of hp laptop and put it in a dell inspiron 1525 now I have no wifi

Question

I'm not familiar with ubuntu at all, I haven't the first clue about how to get my wifi to work now that I've changed laptops. As I have already said I don't know what I'm doing I only use internet explorers (Firefox) and word processing programs. I clicked the little icon for internet in the top right of the screen but it won't connect or even acknowledge that there's available wifi connections. If I plug it into the internet cord it will connect but that's it and I need to be able to take my laptop to other rooms.

Answer 1

First make sure that the computer even has a WIFI module in it. If it does try to bring the driver back to the most basic driver then update it back up to the correct modern driver.
