Just thought I'd post a quick follow-up for anyone interested. My G.Fast connection went live yesterday and after, initially, being underwhelmed by it (Openreach engineer couldnt get more than 35MBps to start with), it seemed to sort itself out and by the time the engineer left, I was getting around 120MBPS. A day later that seems pretty constant.
On the downside, I'm not convinced that the wifi power of the router is significantly better than the old one. It is better, but I still see quite a drop-off in speed as I move further away from the router. Having said that, the higher starting speed does make this less of an issue than it was before.
Time will tell how this works - it took me a while yesterday to get everthing hooked back up to the network, so I havent had any chance to really stress test it yet. One thing I will try is to temporarily kill the separate Unifi Access Point I set up and connect everything directly to the SKY SSID. I originally set this up, because I found that the old router couldnt cope with much more than the SKY Q system - once we started using ipads/ laptops/ALexa, etc., we'd start getting blue screens, with Q boxes dropping connection. That solution did cure it, but I want to see if the new router and faster speed will now cope with this.
If all goes well I may yet add booster point/s, to boost th signal in the farther parts of the house, but lets see how we go first!
By the way, the engineer from Openreach, was brilliant. Really helpful and keen to make sure that all was ok before he left me. He made a couple of calls to Sky whilst sorting the initial speed problem (second time because he wasnt impressed with the first person he'd spoken to!) and also changed the wiring coming in the outside of the house to make sure it wasn't too old/tarnished (it was).
