Ubuntu – Dell inspiron 1545 wired and wireless do not work

When I realized my wireless wasn't working with ubuntu, I plugged my laptop in to try and figure out the problem online – only to find it doesn't work that way, either. The problem isn't my internet/ cords because I'm using both right now via my wireless desktop.

I'm just getting in to ubuntu and would appreciate any assistance. I've looked around but the only similar questions I could find were about the wireless problem – but I have to deal with the wired problem, first.

Let me know what info I need to give.
