Product: HP 290-p0056 desktop
Operating System: Microsoft Windows 10 (64-bit)

I've been getting disconnects with my RTL8821CE 802.11ac PCIe adaptor. I'm aware that Realtek is having issues with it, thanks to @Paul_Tikkanen. I've done the usual things to attempt to resolve it. I want to share two things I noticed that are odd.

 

My wifi driver is the latest available for my system (1803) from the Microsoft Update Catalog, dated 4/12/2019 version 2024.0.9.101. My router firmware is also the latest available.

 

netsh wlan show drivers says "Radio types supported: 802.11n 802.11g 802.11b 802.11ac 802.11n 802.11a"

netsh wlan show interfaces says "Radio type: 802.11n"

 

Two questions. First, why does netsh wlan show drivers list 802.11n twice? It didn't do that before.

 

Second, the advanced wireless properties for my network adapter in Device Manager only offers 802.11 a b & g for Wireless Mode. There is no choice for 802.11 n.

 

A friend has the exact same desktop and WiFi adaptor. He is using an older driver from last year, and his DOES list Wireless N as a choice. So it is obviously the driver that decides the choices there. Thoughts? Is this what Realtek has messed up?
