Cant figure out a WiFi bug in a tablet


As I’m getting ready for the burn I’m trying to repurpose an older Android (Asus Memo Pad7) to use for a PB controller. Every other android device I have works fine. The tablet is running lollipop 5.1.1.
It will initially connect to the PB and load the gui for about 2 seconds then drop the connection and turn off WiFi with a message of try again later. No matter what I do it will not stay connected and turns off WiFi.
Is this an Android 5.1.1 issue? Has anyone seen this and able to fix it?
I’ve done a complete reset on the tablet multiple times but it doesn’t help. It only does this on the PB Pico board.
