I have BT Home Hub 5. I do not use the wifi on this, instead I have three Whole Home Wifi Disks throughout the house.
For the last year or so, the internet (Fibre with BT Halo 3) drops once a day for about 10 minutes. This last weekend, it's been on and off constantly (10 mins on, 5 mins off etc).
There's an engineer supposedly coming Wednesday, so fingers crossed.
Am curious if it also makes sense to upgrade my Home Hub 5 to a Smart Hub 2 if I'm already using Whole Home, or is there no benefit (and only possible issues) if I'm not planning to use it for Wifi.
Its quite possible the HH5 cannot cope with the throughput of FTTP, as its quite old now.
Ask BT for a Smart Hub 2, and simply turn off the wireless, as it will interfere with the Whole Home network.
