Notebook Wireless and Networking

We bought this laptop about 2 years ago and I'll say the Wi-Fi has never been great. Spotty connection, slow to connect to a chosen network, slow speeds at times...but in the last couple of days, the Wi-Fi speeds have plummeted to between 5-10Mbps on a Wi-Fi 6 wireless network with 200Mbps download speed service.

I have tried moving the computer around to avoid deadspots, tested other devices right next to the laptop, and we've even experienced slower performance with this laptop outside the home. In all cases, other devices are getting much higher speeds in line with what the network should be providing.

It's running Windows 10 Home Build 19044.2006 Experience Pack 120.2212.4180.0 and the RTL8821CE driver version is 2024.0.10.226. There are a few things that stick out to me that might be relevant:

1. In the Advanced settings for the Realtek adapter in Device Manager, "Wireless Mode" only offers options in the range on 802.11a up to 802.11a/b/g. This worries me that I'm stuck on 802.11g as my top speed.

2. In the Hardware and Connection Properties for my wireless adapter, there are two Microsoft Wi-Fi Direct Virtual Adapters (strangely numbered #11 and #12). They are listed as disconnected, but I've never been aware of them before.

3. In the network adapter area of Device Manager, there are several WAN Miniports listed alongside my Realtek Wi-Fi and Bluetooth adapters. Could these be interfering with my connection?

I've seen many questions around the internet about the network card, but are there any tried and true methods to get my Wi-Fi working correctly again?

I'm really hoping someone out there has some idea of what might be going on. Otherwise, should I consider replacing the network card?
