Chromecasts Not Working on Telus Wifi Hub

Has anyone had issues with chromecasts on a Telus wifi hub? We recently switched to Telus and ever since the chromecasts are intermittent at best with their connectivity. When streaming music, the connection drops every 30 seconds then reconnects about 5 seconds later and repeats indefinitely. My phone only recognizes about half the chromecasts on the network at any given point in time. Has anyone else had this issue? I'm not sure what to do, but it's very frustrating to try and deal with.

Try turning Smart Steering off if you have it on. It might be the devices flip-flopping between the 2.4 and 5 GHz WiFi. With Smart Steering off it forces the devices to stay on whatever WiFi you set it up on.
