Dell Latitude E6530 Broadcom and Wireless connectivity Issues? Help?

So I bought Dell Latitude E6530. I noticed they were a lot of things missing, since I went to see in the Device Manager. After fixing so many, I have ended up with these. When I connect my laptop through A wire cable, it does connect but when I slide the wireless switch, it enables the Bluetooth but not the wireless, I have enabled Wireless in BIOS and yet nothing. Please help me someone it will mean a lot. I have done as much as I could but now If you can help me out.
