PT14-51 WLAN slot interface (CNVio2 vs PCIe) — Wi-Fi 7 compatibility check

nicklevader

Model: Predator Triton 14 — PT14-51-7979

Hello Acer Support,

I need to replace/upgrade the internal WLAN module and want to confirm interface compatibility for my unit.

1. My laptop shipped with Killer 1675i / Intel AX211, which uses Intel CNVio2 on the M.2 2230 E-key WLAN socket.
2. I understand that all Intel/Killer Wi-Fi 7 modules available today are either:
   • PCIe/USB (“NGW”) (e.g., Intel BE200 / Killer BE1750), or
   • CNVio3 (e.g., Intel BE201),
     and therefore none use CNVio2.

Questions for my exact PT14-51 unit:

A) Will ANY Wi-Fi 7 module work in this laptop?
(If yes, please specify which models are supported.)

B) Does the internal M.2 E-key WLAN socket on this PT14-51 expose PCIe signaling (i.e., supports PCIe/USB “NGW” operation), or is it CNVio2-only?

• If PCIe is present, would Intel BE200 / Killer BE1750 be supported?
• If PCIe is not present (CNVio2-only), then I understand Wi-Fi 7 modules would not be compatible.

C) Is there any BIOS/EC whitelist that restricts which WLAN modules the system will accept?

I’m trying to determine whether a Wi-Fi 7 Killer-series card can be used, or if I must remain on CNVio2 Wi-Fi 6E (AX211/AX411 class).

Thank you for confirming the WLAN slot’s interface (CNVio2 vs PCIe-routed E-key) and any approved module part numbers for my serial.

Best regards,

-Chris

Hi nicklevader

Your Predator Triton 14 (PT14‑51‑7979) shipped with the Killer 1675i / Intel AX211, which is a CNVio2‑based Wi‑Fi 6E module. That means the M.2 E‑key slot in your unit is wired for CNVio2 only, not for standard PCIe/USB “NGW” cards.

• Wi‑Fi 7 modules today:• Intel BE200 / Killer BE1750 → PCIe/USB (NGW)• Intel BE201 → CNVio3None of these are CNVio2, so they are not compatible with your slot.
• Result: No current Wi‑Fi 7 card will work in this laptop. You are limited to CNVio2 modules such as the AX211 or AX411 (Wi‑Fi 6E).
• Whitelist: Acer does not maintain a BIOS whitelist for WLAN modules on this model, but the physical interface (CNVio2) is the hard limit.

So in practice, you cannot upgrade this PT14‑51 to Wi‑Fi 7 internally. If you need Wi‑Fi 7, the workaround is an external USB adapter once those become widely available.
