Hello,


I'm using an old HP AC146tx laptop. I have a question about the WiFi card. It came with an RTL8723BE 2.4Ghz card. However, because it was damaged, I bought a second-hand RTL8821CE Dual Band card. When I installed it, everything worked fine, but when I checked the connection speed, I only got 57-72Mbps at 5Ghz. I checked the Wireless Mode settings in Device Manager and found that the maximum menu options were 802.11 a/b/g. However, when I checked using CMD, the Connection Type showed it supported up to 802.11ac, but the Radio Type in CMD showed it only connected to 802.11n. I've tried installing many drivers from HP to Lenovo, but none of them enabled the 802.11ac option.


Is this due to the motherboard's default 2.4Ghz WiFi card?

 

Additionally, I briefly used a Linux Mint USB Live Boot, and when I checked my home router's connection speed, it was reaching 150Mbps, while on Windows 11 24h2 it was only 72Mbps.

 

Sorry if this is too long and messy, as I'm using a translator.
