In my situation I've tried a couple of different modems for use in bridge mode. The business smart hub gives me a better connection by a decent margin. Well worth a £10 purchase.
Yes, I have just ordered a brand new sealed BT Business Smart Hub (Latest) for £20 so it's not exactly breaking the bank.
I can then keep the HG612 as a known and untouched working backup device.😁
Can't understand the need to have a BT hub in modem mode when the HG612 is more than up to the task. I would never waste money on ISP kit.
Particularly when the stats are so easily obtainable.
