Philips Wiz A21 Smartlight Keeps Disconnecting

[wireless]

The light pairs with no problem. It is detected in the app and by my Alexa integration. The Telus wifi access point sees it on the 2.4GHz band. After 15-30 minutes, I get these messages.

Communication with server failed.
This light is unavailable.

The Telus wifi access point still sees it connected on the 2.4GHz band but can't communicate with it.

After I turn the light off then back on, It re-connects and is detected in the app and controllable by my Alexa integration.

This started Friday February 3 when my wifi router was replaced with Telus NAH and Boost2 AP
I used my neighbours wifi with no issues. They have the older Telus Actiontec router that I had, which worked flawlessly with the Wiz light.

I've tried restricting the light to 2.4GHz.
I've tried using the Telus Smarthome 2.4 GHz SSID
I've tried opening ports 38899 and 38900
A Smartlife 2.4GHz plug works with no problems. Just the WiZ light keeps disconnecting.

Please help!
