Try modifying the password or removing the password (just to test) to see if it may be related to that. You could also try changing the wireless security as well on each band to try and narrow down what it could be. After logging into the Archer A7, go to Advanced > Wireless > Wireless Settings to get to the menu you need to make those changes.

Also, if you have smart connect enabled, try disabling that.

@Tony thanks. I tried that and other things but none would work. Then I tried Linux 64bit and it worked as soon as I logged in. But still don't know why 64bit works but 32bit doesn't

Seems very odd as our routers don't really care what connects for example you can connect an Amazon fire tablet or a Nintendo Switch.

I would reach out to your local support team here: https://www.tp-link.com/support/

They should be able to work with your issue in more detail to see what the cause would be.
