Gigafast Slow Speed

[Cammy28]

Hi, I've had Sky's full fibre at 76mbps. 

Sky Q,

Sky Minboxes x 2

 Sky Booster

 all working fine with stray speeds. 
I had Gigafast installed, and advertised as 900mbps with a guarantee of 600mbps. 

As the Sky Hub was not saving the settings, I had a new router sent to me and I carried out all the reboot process and successfully connected my hardware. At this stage I was only getting speeds of about 120-130 mbps download speeds, so reset all the router, and connected only the Sky products and this only returned speeds of 120-130mbps, so obviously a problem somewhere as Sky Service Checker returned no problems. 

With the assistance of Sky Broadband specialist, we changed the routers channels, the signal 2.4GHz and 5GHz and the new router still does not save the settings and the constant download speed is 120-130mbps. 

Can anyone suggest further configuration settings that I can try without the need of an engineer?

I'm tech 'Savvy' and an expert in nothing.

TIA

@Cammy28 there are acouple of points that may help. Due to a bug the web interface of the black Sky hubs can often not save changes if the device being used is running ios and Safari. The best is to use a non Apple device ideally connected by ethernet but if you only have Apple kit try Chrome but you may need patience as that can take several attempts.

The second is that the standard Sky SR203 hub only uses wifi 5 so you wont ever get 900Mb/s from it over wifi it seems to top out at 6-700Mb/s on my tests which is far more bandwidth than most wifi devices require. If you need the fullband width on a single device use gigabit ethernet connection. If your device supports wifi6 it maybe worth upgrading to a wifi6 capable router. Sky offers an upgrade package called Wifi Max which comes with the SR213 hub which is a wifi6 unit. However that peak speed would only be achievable in the sammearea as where the hub is placed. You can buy third party kit but it can be very expensive trying to get high wifi speed in every room which only has marginal affect on speds apps run at.

Both wifi5 and wifi6 are subject to interference and while you can switch channels in many homes you may have to do that frequently as your neighbour's routers switch as well.

Thank you @Chrisee  I'm heavily invested into the Apple environment so will try your suggestions. Would introducing an Airport Time Capsule assist or would this just cause more issues.

Apple AirPort hardware is now really old: the last (Gen 5) release was a decade ago.
