I wanted to upgrade the wifi card in my t420, from what it came with(just said ThinkPad b/g/n on the receipt), to the Intel Centrino Ultimate-N 6300 (Puma Peak) 3x3 AGN since i needed to be able to use a 5ghz network. I specifically choose that puma peak one, because i saw in the t420 manual that it was supported, and i'd heard of issues with unsupported cards.
So i finally got the wificard, and even though i picked a supported one i get this message:
1802: Unauthorized network card is plugged in - Power off and remove the miniPCI netwok card (8086/422B/8086/1101).
System is halted
What have gone wrong? And could i be because this card wasnt ordered directly from lenovo, but from some random danish vendor who had it? I've tried to google around, but without luck.
Only thing i can think of trying right now is taking it out again and tripplechecking that its seated properly.
Hope you guys can help me, and i hope i wont have to hack the bios whitelist or something, seeing how this network card should work without that.
Thanx in advance!
after some more searching and finding this link http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-69757 it would appear that the issue is due to the card not having been bought directly from lenovo. but they dont have the card available in my country (denmark). which basically means im screwed and would have to find some sort of workaround solution. fml

Yes, this is expected. Each computer manufacturer has their own whitelist for wireless cards for standards compliance. Hence, a non-Lenovo card will cause this error
You'll need to use a modded BIOS, which may or may not be available for the T420 yet.

Yeah alright. Thx for confirming.
You wouldnt by any chance know more of the actual risks of flashing and using modded BIOS, vs flashing and using the regular ones, would you? Wanna know if its worth the risk, or if i should just try to return that wificard, get my money back, and just live on the internet tethered from my phone while at school.

I bought a T420 after being ASSURED in no uncertain terms by a sales rep, and a tech support rep I called when I didn't trust the sales rep, that Lenovo doesn't restrict the cards a Lenovo laptop can boot up with.
Lenovo sales and support are misinformed. See this chat record as just one example:
Thank you for contacting Lenovo Sales Chat. My name is xxxxx Happy to help you today.

Thanks. Alas, my laptop's telling me about the whitelist the hard way:
... because I believed the support reps, went ahead, and purchased it.
Angry now. Very, very angry, because the store doesn't say anywhere "3G ready (so long as it's a lenovo branded card)", the spec doesn't mention the restrictions on mini-pci-E cards, etc. Since I got repeatedly misdirected by support and sales people, this is an oppurtunity to make Lenovo make this right.

BTW, I've never seen another vendor have this restriction. My 3G card worked great in the Dell I bought it in (obviously) and an Acer machine. Non-Dell cards work fine in Dell machines - I replaced my wifi card in my XPS M1330 with an upgraded Intel Advanced N part off eBay (which amusingly happened to be Lenovo branded) and it worked perfectly, thankyou very much.
This is just Lenovo scamming customers for money, and I'm now an extremely angry new Lenovo customer - hopefully soon ex-customer.

Thanks, I didn't know HP did this too. Dodgy.
Blog post on this matter here. http://blog.ringerc.id.au/2012/06/lenovo-sales-and-support-reps-dont-get.html
It's certainly not an FCC requirement that they actively prevent their machines from booting with 3rd party cards, as many other machines without this misfeature are FCC certified. Lenovo can't sell systems with random 3rd party cards installed without recertifying them, but it isn't trying to do that and that isn't the problem. In practice, it means 3rd parties can't re-sell a Lenovo laptop with a 3rd party card and claim that the combined bundle is FCC certified, and that's about it.
I don't live in the US and the Australian certification rules are different anyway. I just resent their redirection of blame to the FCC; this isn't an FCC issue, it's weak excuse for a cash grab and (if we're being charitible) an attempt to reduce support costs. It's like the DVD CCA claiming that DVD region coding is copy protection because it happens to rely on a separate feature (DVD CSS) that is intended for copy protection. Pretty laughable.
If they want to reduce support costs, just have the machines' support tools "taint" the machine when it has a 3rd party card in it. Diagnostics tools would modify the codes they returned to give to phone support with an embedded indicator that there's an unsupported configuration. Remote diagnostics tools would flag the machine. Have the machine play a different boot-up beep audible over the phone when a 3rd party card is installed. There are lots of much less customer-hostile approaches if reducing possible support burden is an issue. I'm not convinced it has anything to do with it, though.
Now, time to see how the firmware update bootable ISO is packed. I'm reasonably handy with the EFI developer toolkit and a disassembler; let's see just how hard it'd be to come up with a reliable patch for their EFI firmwares. Assuming they're not digitally signed, which alas they probably are in these Secure Boot days...
