Lenovo Z710 - Unauthorized Wireless network card is plugged in

I have a Lenovo z710 laptop. It comes standard with the Intel Wireless-N 7260 (7260HMW BN). Wanting to speed up the exchange of files via WiFi, I bought the Intel Dual Band Wireless-AC 7260 (7260HMW). After installing the laptop, I was greeted with a nice message:

"Unauthorized Wireless network card is plugged in. Power off and remove it"

It turns out that in the bios there is a so-called whitelist and this list contains information about cards authorized by Lenovo. It surprises me a bit, after all, it's almost the same card :/ I've read that there are ways to do this, such as modifying the bios by adding the card ID or turning off the whitelist check, changing the card ID. Unfortunately, this is beyond my skills. My English doesn't allow me to understand English-language forums well either. Maybe one of the good forum members could prepare a modded bios for me? Is it safe to upload it at all?
I've also seen a program called no1802.com somewhere that does the trick, but it was for an older model. I couldn't find any info about the z710 anywhere...

I found a list of supported card models and it says Intel Dual Band Wireless-AC 7260 (7260HMW). The ID is the same as on the card. I don't care about it.

Hello.
The card has a different Subsystem ID and if not for the blockade - it would work properly. Just a little maliciousness from Lenovo (but not that only Lenovo is malicious - Dell and HP do the same). You are left with:
- purchase a card for Lenovo (you will recognize it by the FRU number - a designation characteristic of Lenovo/IBM equipment, in this case FRU S/N: 04W3814). Such a card, if the laptop actually supports AC-7260, will definitely work and it is the safest option.
- modify the BIOS - this is a bit of a dangerous option. There was a topic about this laptop here, but from what I read in a hurry, the new BIOS was loaded with a programmer. Perhaps there is already some "ready-made" that can be uploaded normally - you have to look for it. This is the less secure method.

What about changing the card ID?

In theory, you can reprogram the memory chip on the card, which includes the device ID among other things. I have never done such a trick, but it is theoretically possible and probable.

Breaking down the BIOS of your laptop in the latest version, I found support for the following Intel cards:

8086:08b2 80864262 Wireless-N 7260
8086:08b2 80864270 Wireless-N 7260
8086:08b1 80864070 Dual Band Wireless-AC 7260
8086:08b2 80860270 Dual Band Wireless-AC 3160

Since your original card is Wireless N I'm guessing it has a hardware ID of one of the first two (check device manager out of curiosity). Card number 3 is Wireless-AC 7260 and such ID is on the list allowed by BIOS. You can also look for the AC-3160 card, on the white list there was also such a model (ID 4). AC-3160 support is mentioned in the last update, so only the latest BIOS will confidently support it.

This is the first on the list. So it is irrelevant that the new card is theoretically supported by the bios, the problem is that it is not "intended" for Lenovo?

Maybe it's worth asking for a modded bios?
How safe is it? (I don't know this forum)

I found this thread:

https://www.bios-mods.com/forum/Thread-REQUEST-Lenovo-Ideapad-Z710-Whitelist-removal

Do I understand correctly that there is a link to the modified bios in the last post?
Can you throw it from dos or do you need a programmer?

That's the error right here. Yours is apparently not "supported" by the BIOS. Or more precisely - it is not on the allowed list, so it is blocked. For it to be "compatible", according to the data I extracted, it must have exactly the ID:
PCI\VEN_8086&DEV_08B1&SUBSYS_80864070...

And to make you realize how many other possibilities there are (of which a large part is AC-7260, the rest are in the N-7260 version) have a look here:
https://pci-ids.ucw.cz/read/PC/8086/08b1
https://pci-ids.ucw.cz/read/PC/8086/08b2

Especially at the bottom, there's a whole list of IDs appearing in place of SUBSYS - even though they're the same cards. From these two lists, the identifiers I listed above will match. Probably cards made for Lenovo have them.

As for the BIOS from the last post, it looks like a complete solution with a DOS flashing program. There is also a short instruction manual in the archive. Unfortunately, there are no posts confirming its operation (correct or incorrect). I've downloaded modified BIOSes from this forum before, but there's never any guarantee of success (especially if there are no comments on how the rework works).

I need to know the risks. The laptop is under warranty. Can I revert back to the original bios? In the worst case, if something goes wrong, will a programmer have to be used? How much does such pleasure cost? What else should I know before trying to upload?

Worst case scenario, you will need to flash the BIOS with a programmer if something goes wrong or the BIOS is bad. Ask for prices at local computer services, I suspect that around PLN 100 may cost something like that, maybe even more (service issue).

It's hard to decide Also tell me if I will lose the warranty if I upload with a programmer. The bottom flap can be removed, for example, to replace the disk or the mentioned card, but where to get to upload the bios I do not know.

I got this when trying to upload. What does it mean?

It's good for this bios. The question is: Will the card with the number FRU 04W3814 definitely work? Because that's what you can find on ebay.

It should work, but I would make a quick call to Lenovo support to confirm it, because there are no guarantees.

I will, but tomorrow, support until 6 pm. Bios checks the card by ID or FRU number? Because I'm reading conflicting information about it.

After the PCI ID - the identifiers of "compatible" devices are sewn into the BIOS.

And those with a compatible (your) PCI ID is marked by Intel - FRU Lenovo? Forgive me if I'm asking a stupid question, but I like to be clear

Lenovo parts (all) have a FRU number, parts for Dell have a DPN number, parts for HP have an SPS number - each manufacturer has its own internal numbering of all components. When you see the pictures of this card (just google pictures), you can easily distinguish which card fits which computer

So yes. I was on the phone for an hour, first the hotline, then the service in Suwałki. No one guaranteed me that the bios would accept a card with the FRU 04W3814 designation. They don't have that data. They say that sometimes they come to network cards for specific models, and then it turns out that the bios does not accept them and they send back.
They offer me two solutions:
1. Send them a laptop and they will select a card (I'm supposed to get a quote tomorrow/day after tomorrow, but I suspect it will be expensive)
2. Send a laptop with a new card (the one with which I have a problem), and they will modify the bios by downloading the whitelist, upload it with a programmer and everything will be fine. The service manager says there will be a note that they did it and it won't affect the rest of the warranty. The price they want for this service is PLN 123.

Well, now I don't know what to do. Should I send back the card and buy the one from FRU and try it, or be tempted by option 2. The downside of this would be that I couldn't update the bios later. And I'm not sure that the modified bios will work properly... Any suggestions?

So I bought an Intel Dual Band Wireless-AC 7260 (7260HMW) card with the FRU 04W3814 designation and ... it works! ID:
PCI\VEN_8086&DEV_08B2&SUBSYS_42708086&REV_4B
I am surprised, according to the links sent by a colleague, it is a Wireless-N card?!?
