Thank you for posting on the TP-Link Community.

Can you please verify if there are any other devices that connect to the AX6000 5G network, are they stable or not? If other devices can connect to the 5G network stably, while the Windows 10 has an issue, you are suggested to check the settings or the adapter on it.

Generally, the router wireless channel is set to auto and leave it to decide about the channel width and channel on which it will work. In particular situations (congested Wi-Fi environments) it's better to set it on a channel less crowded. For that purpose you'll need to do a scan with any Wi-Fi analyzer to see which channel is less crowded and select it manually.
