Thanks for the reply. It's not necessarily the setup of the Orbi I'm having problems with, it's that it's just not performing very well. I have an old Orbi RBK23 set which has been great for years, but couldn't quite handle the throughput I want from the 500Mbps connection I have in the locations I need it to reach. So I picked up an RBK763 set thinking newer=better and I understand how to set them up, but the performance has been all over the place to the point I'm about to give up. The 5GHz band seemed to be terribly short range to the point many devices were connecting on 2.4GHz, and even when something did connect on 5GHz it was very up and down. I thought I'd cracked it the other night when I finally hit 500Mbps from the required location for an extended period, but then by the morning it was gone again. This is going through the Power Hub (with wifi switched off on the Power Hub), and also removing the Power Hub and connecting the Orbi system to the ONT directly using the Vodafone supplied login details. Reboots, channel changes, all sorts tried. I've just reset it entirely to give it another go from scratch in case something had somehow gone wrong somewhere, although I might even just go back to the RBK23 and accept I'm not going to be able to use my connection to the max if I can't get it running as expected.
The Power Hub router isn't actually that terrible and up things can work very well in general, but the range of it is awful - I wasn't expecting miracles, but I was expecting a bit more. I can't even get devices to connect at the other side of the house, and it's not that big (standard modern newbuild, about 64 square metres / 600 square ft internal on each of 2 floors - I do want and need it to reach into the small back garden too, of which there's utterly no chance). So I'd consider a Wifi Booster if it is effectively Vodafone mesh that just extends this system, but not for the quoted cost which would be £192 (extra £8 per month for 24 months) because that's insane. I suppose I should ask what Vodafone support will allow before attempting something like that if the general answer is unclear, it's just quickly become apparent that it's a bit of a crap shoot whether you find someone who actually knows what they're on about.
