WiFi Pods affected by recent router update.

Hi,

I have 3 WiFi pods scattered around my home and we're working fine, displaying an excellent signal/communications. 

I've recently noticed patchy connections so checked the pods via the app. There all showing a fair connection now, so moved one 2 mtrs away from the router in the same room and still showing fair.

checked the router logs and found a software update had taken place.

Anyone else experiencing a similar issue or have a fix?

thanks
