[REQUEST] Removing whitelist from Lenovo G500 Laptop

I am requesting for some help in removing the wi-fi whitelist that my laptop, a Lenovo G500 (not G500s) has.

The download Link for the Bios is:

My BIOS is 78CN23WW(V2.01) and like it says, I am on 2.01

I am afraid I don't know how to check the PCI ID of my wireless card but if someone can show me a link or a program that can do so I am willing to provide it (I'm afraid that in the thread to do this requests it doesn't teach you how to do it for those like myself that aren't too tech-savvy).

Under Device Manager it says I have a Broadcom 802.11n Network Adapter with a driver of 6.30.59.87. I tried looking for information from Broadcom's and Lenovo's websites but I couldn't find anything that looks like an ID. I have an Atheros Ethernet card if that helps. I've been scouting how unrealiable Broadcom wireless cards are and I want to get rid of it ASAP for an Intel one that also includes Bluetooth (as the Broadcom does not have Bluetooth)

The Backup of my BIOS is:

I also have just two quick questions:

1. I am on Windows 8 but if I flash my BIOS, install the wireless card and then upgrade to 8.1, will it affect my card or BIOS? Will I have to flash it again or will it brick my laptop? Is it safe to do?

2. If a new BIOS version comes out, what should I do? If I update the BIOS, will it affect the wireless card? Will I have to flash the BIOS again? Will it brick my system? Should I prevent myself from updating the BIOS version?

Thank you to anyone in advance who can help me resolve this situation. Please reply if you cannot access my backup file on Dropbox (Dropbox has been acting funky for the past few days for me
