Ok, here is the problem. I've had this computer for about 3-4 months, it has Windows Vista installed. The machine is an HP Pavilion dv2000 laptop.
It has a built-in wireless adapter that when I turn from "left to right" would change from "blue to red" respectively. So I would know the wireless card was working.
Yesterday my wife bought a Dlink WBR-1310 wireless router and suddenly the thing stops working. I set up the router, which I believe I've done correctly... but I can only get a connection if I physically connect the network cable from the router to the laptop (or directly into the modem). For the life of me I cannot figure out what the problem is. It "appears" to me that there is something wrong with the network adapter. I can only find one in device manager (cannot seem to find the wireless at all) and my HP assistant doesn't open anytime I double click. I even tried to download the new HP wireless asst. drivers and still no luck!!!

I have no idea what else could be the issue, but I have had more issues with this PC over the past 3 months than I think I've had with any other.

In addition to that, my CD-Rom drive cannot get its' drivers updated and that doesn't even work!! The laptop came with vista and they didn't give me a disk so I can't even format it which would hopefully solve the problem? Maybe? I dunno, but any help is surely very very appreciated!
Thanks very much!
Edit: I forgot to mention that the light NEVER turns blue anymore, no matter if the router is on/off/connected/not-connected etc. Doesn't matter what happens, always the same result. Just wanted to add that in (helps to say why I think its the PC and not the router).
In addition (more edits)

I noticed people with similar problems asking for ipconfig /all so I figured I should do the same
