I have a Realtek RTL8821CE 802.11ac PCIe Adapter for HP Pavilion Desktop - TP01-0034. The speed is slow, so I want to replace it with an Intel dual band 802.11ac adapter. What is a compatible model?

I suppose this wifi card is the same regardless of the device, i.e., laptop vs desktop (I have a Pavilion Desktop - TP01-0034).
When I go to Device Manager, the description says Realtek RTL8821CE 802.11ac PCIe Adapter but when I go to the Properties and click the Advanced tab, I see only 802.11d and 802.11n (listed twice for 2.4 and 5.2 Ghz). I don't see anything that says 802.11ac. The 'Wireless Mode' property says 802.11a/b/g. The driver version is 2024.0.10.209 dated 12/4/2019. I tried uninstalling the driver but it reinstalls the same driver. If it's a 802.11ac adapter, I would think there should be a property for 802.11ac.

There aren't any Intel wifi adapters with a single antenna that would work in your PC.
There may not be any AC setting in the advanced settings for the card in the device manager.
it depends on the model of the card.
Did you try these drivers for the card? These are the latest ones that I know of.
Check the actual connection speed of the card. With an excellent signal on the 5.0 GHz wifi band with an AC router, it should be connecting at 433 MBPS.
You can check the connection speed by going to the Windows control panel>Network and Internet>Network and sharing center.
In the View your active networks section click on your wifi connection.
It will show the connection speed. The max will be 433 MBPS.

Thanks Paul. I got a USB adapter and am getting 867mbps. It's a Techkey 5dBi High Gain Antenna with a Realtek 8812BU driver. It's pure plug and play, I didn't have to install any drivers, Windows did that automatically. I've been using it for a week now and it always connects, no dropped signals.
