My router randomly disconnects from the internet. It will work fine, then will suddenly not have internet access.

The router is physically connected to two desktop PC, a television, and a WAP. (I know this device is meant for businesses but I'm using it at home anyway.)

This problem has worsened when I started using a new WAP. It's a Netgear WAX214 (AX1800) and is connected over a LAN port using DHCP. I used to get disconnects every week or so, but now it's every 1-2 hours. Sometimes just the WAP loses internet, but most of the time it's the router.
