Strange Issue with Internet Access Regarding SSD

I need some help getting my computer to access the internet in certain situations. First, a bit of background ont he issue. I bought the computer and the SSD at the same time, but due to issues, I had to just work with the OS on the HDD for a few weeks. Yesterday, I got the SSD into perect condition, and installed Windows 7 on it. I didn't remove the OS from the HDD just yet so that I could have a backup. The OS installed perfectly, but when it came to network adapter drivers, it got interesting. I no longer had access to a CD player, so I first tried copying the old drivers folder from the OS folders on the HDD. No luck. I then realized I could move the driver CD's files to a flash drive using another computer, and the drivers installed fine, but the computer refused to recognize them. And something is up with internet in general as well. I lugged the tower over to the router, but even when it was directly wired in, I couldn't connect. Could someone please assist me with this?
