Network Issues Mediatek MT7922/Hardware Whitelist

[Lukas984]

Hi everyone,

I am hoping someone can help me with a frustrating Wi-Fi issue I’m experiencing on my HP Envy 15-fh0777ng running Windows 11.

The Problem: My university requires "Random Hardware Addresses" (MAC randomization) to be enabled in Windows 11 settings to connect to the campus network. When I connect, everything works perfectly for exactly 30 minutes.

After 30 minutes, I remain connected to the Wi-Fi access point, but I lose all internet access ("No Internet").

The "Workaround" Loop: To get it working again, I have to do the following cycle:

1. Turn OFF "Random Hardware Addresses."

2. Toggle Wi-Fi off and on.

3. It works for another ~30 minutes.

4. The error returns.

5. I have to turn "Random Hardware Addresses" back ON and reconnect.

6. It works for 30 minutes, then fails again.

I am essentially forced to toggle this setting back and forth every half hour to maintain a connection.

Troubleshooting Steps Taken:

• Drivers: The University IT support advised me to update my WLAN drivers. I have installed the latest drivers for my current card (Mediatek MT7922), but there was no improvement.

• Hardware Swap Attempt: I attempted to replace the current Wi-Fi card with an Intel network card to see if it was a hardware compatibility issue.

• BIOS Issue: When I installed the Intel card, it was not recognized in the BIOS at all.

My Questions:

1. Has anyone experienced this specific 30-minute timeout with Random Hardware Addresses on Windows 11? Is there a registry fix or power saving setting that causes this?

2. Regarding the hardware swap: Does the HP Envy 15-fh0777ng have a BIOS Whitelist for network cards? Is there a specific list of compatible cards I can check, or a way to bypass this so I can use the Intel card?

Any help would be greatly appreciated as this is making it very difficult to work on campus.

Thanks!

Hi:

What is the driver version did you install?

I found this driver which is newer than what HP has on your notebook's support page:

Version: 3.5.0.1349

sp165645.exe

Fix and enhancements:

- Fixes an issue that causes a blue screen event to occur with error code 0x7E. (MT7902, MT7920, MT7922) - Fixes an issue where the WLAN adapter cannot search for any access points after the system resumes from hibernation. (MT7902, MT7920, MT7922) 

The only other model Wi-Fi card you can install in your notebook according to chapter 3 of the service manual is the Realtek 8852CE Wi-Fi 6E Bluetooth 5.3 WLAN    HP part # N19618-005.

Normally, Intel cards such as the AX210 won't work in an AMD notebook, and HP does not release any information regarding whitelists, but clearly your notebook has one.

Thanks for the detailed reply and the link!

I actually found that specific driver version (3.5.0.1349) in the Microsoft Update Catalog earlier and installed it manually via Device Manager. Unfortunately, the behavior hasn't changed, and the 30-minute disconnect issue persists even with this driver.

Regarding the compatible hardware: You mentioned the Realtek 8852CE (HP part # N19618-005) is the supported alternative. Do I strictly need to source the original HP spare part (with the specific HP Part Number) to get past the whitelist, or would a generic third-party card with the same Realtek 8852CE chipset likely work as well?

Thanks again for your help!

You're very welcome. 

I recommend that you search by the HP part number, not the model of the Wi-Fi card. 

You should be able to find one on eBay. 

Here's why:

If you look at the Realtek RTL8852CE Wi-Fi driver setup information file, the drivers are set up by PC manufacturer, so if the BIOS has a whitelist, the hardware ID for a RTL8852CE designed for use in a different manufacturer's PC it may be rejected by your notebook's BIOS, because each hardware ID is unique, so it is easy for HP to exclude all ID's other than the one for the card that was listed for the HP notebooks in the whitelist.

So, buying any old RTL8852CE card wi

HP sells the card on their parts store website, but it is ridiculously expensive at €77.37.

I found one on eBay for less money.

If you look at the photo on the eBay listing you can see that the SPS# on the card matches the HP part number, so if you come across a card that has that SPS# it should work.

Thanks again for the help and the link!

I tried searching for that specific part number locally, but it seems difficult to find. I will probably just go ahead and order the one you linked. The import fees/shipping from the UK are a bit high, but I would rather pay the extra cost to be on the safe side and ensure the card is actually recognized by the BIOS whitelist.

I really appreciate your support in figuring this out.

Anytime. 

Glad to have been of assistance.
