So I bought my dad an X220. It was great, but the wifi didn't work. Thinking it was a network card issue, I popped the card out of my ThinkPad Yoga 12 (an Intel 7260), dropped it in his X220, did a custom BIOS to remove the whitelist, and then left it with him while I returned to college, 2200 miles away from home. I figured that even if that wasn't the issue, the 7260 is a much nicer card than the one that comes with the X220. I ordered a replacement card for my laptop, another Intel 7260, thinking I could just pop it in and be on my way. Well, lo and behold, I pop the card in, and BOOM - Error 1802 - Unauthorized network card. The laptop cannot boot, even though this is the same model card it came with. And, upon further review, I learn that there is no custom bios for this model (ThinkPad S1 Yoga 12).
So here are my options, as I understand them:
1) Order another card of this same model and pray it works.
2) Find a way to customize my BIOS to remove the whitelist (risky).
3) Modify the ID on the network card to be kosher with the whitelist. If recommended, this would require a mini PCI adapter for my desktop, which I would love a recommendation on.
Do I have any other options that would be more expeditious? Is there a cheap and easy solution that I'm missing.
Seriously Lenovo, this whitelist is some baby back BS.
