internet problems for only one ipad in the house

every other device in my house experiences the wifi smoothly except one ipad that will suddenly buffer on a video or show for a really long time and disconnect from zoom meetings. Things I've tried are: connect it to hotspot (it connects to that just fine), reset the devices network settings, reset the ipad, change to the 5g version of the wifi, manually added 1.1.1.1 to the dns. but the problem still persists
