My laptop doesn't show any wireless network connections

So, I happened to do CD recovery a day ago; *Due to forgetting Administrator password* and now my laptop seems to not be able to pick up any wireless connections when there usually is a ton. Also every time my laptop restarts it always loads saying "Preparing for first time use" Like I used the CD recovery again. which I didn't. I thought that maybe it has to do with the Drivers and such, though im not very tech fancy, so I wouldn't exactly know where to find the correct driver to install, and which to install.
Here is my laptop's Information:

If you were wondering, my Network adapters is: Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)
