Amplifi Alien cause Uverse TV to freeze up

Just like the title says.... for some reason whenever I put my Amplifi Alien in the mix it causes my Uverse TV to freeze up.  I had this problem two months ago and disconnected the Alien and thought maybe since some time had passed and a new firmware update had came out it may have fixed the problem but I was wrong.

I am currently using the BGW320 and I have always used the Alien in bridge mode as an access point......I used it this way for over two years and about two months ago when I was still using the BGW210-700 this problem began.........I thought maybe it would play better with the newer BGW320 but it doesn't.

I use ethernet connections for my Uverse TV setup and have no wireless STB's or a WAP.....I used coax for years and for some reason it recently wasn't stable either but has done fine using ethernet.......

Can anyone suggest or is anyone using a newer wifi 6 access point along with Uverse TV with it working correctly and not freezing up? could anyone make any suggestions for a different wifi 6 access point that doesn't cause problems with Uverse TV? any help appreciated...thank you
