-Current Network card: Intel Corporation Centrino Wireless-N 2200 [8086:0891]
+Living in Toronto, the 2.4GHz WiFi band is over saturated and my best wireless throughput was roughly 16Mbps, now with 5GHz Wireless AC, I get an average of 700Mbps. I decided not to upgrade to the latest BIOS and to attempt the whitelist modification on my current version, G4ET62WW (2.04).
-I successfully installed an Intel Dual Band Wireless-AC 7260 wireless card by modifying the whitelist in the BIOS. I've compiled this step-by-step guide with references as I had trouble finding a similar resource online.
+There are two flash memory chips, MX25L6406E (8MB) and MX25L3206E (4MB) (Under frame), according to various resources, I need to flash the 4MB chip. There is also another flash memory chip on the underside which contains the bios settings and password which I don't need to touch.
-<note>
+There are forums for whitelist removal, such as [[https://www.bios-mods.com/forum/Forum-WiFi-WWAN-Whitelist-Removal|www.bios-mods.com]] but I wanted to figure out how to modify the whitelist myself and to only use the forum as a last resort if I'm unable to make it work myself. (Also, I'd still need to figure out the bios reading and writing)
