Hi @kinsercat
Welcome to the Community and thanks for your post!
Sorry for the problems you're having with the wireless signal being broadcast from your Smart Hub. We can't guarantee wireless and everyone's environment is different however there are a few links you can try below to see if you can improve the signal;
How do I change the Wi-fi channel on my BT Hub?
How do I split my BT Hub's SSID (wireless network name)?
Post back and let us know how you get on with this.
Cheers,
Robbie
