Sky Fibre Gigafast

Just signed up to gigafast 900. I'm using the 4.2 hub I received when I joined sky bb many moons ago. Prior to the gigafast upgrade I was only on sky 150.

Skys bb checker shows I'm getting speeds of up to 690 but fast.com shows it's only around 200-300. Should I have been sent a new router with this upgrade or should the 4.2 model be capable of handling the new speeds

@thepostie the hub 4.2 does support the maximum 900Mb/s speeds over Ethernet but tops out around 700Mb/ss over WiFi as it does not support WiFi6 which you need to gat higher speeds over WiFi . WiFi speeds drop as the signal has to pass through solid walls so 200Mb/s a couple of rooms away from the hub sounds normal a lot depends on the layout of your home and how it is built. The faster Hub 6 will give comparable speeds in the same location in most homes but would be faster in the immeadiate area of the hub.

In practice very few if any applications can use let alone need the full 900Mb/s so in practice the performance difference is not important. If however you are handling very large files regularly use an Ethernet cable w ith either hub. To maximisecWiFi speeds ensure the hub are out in the open on a surface so it is above obstructions like radiators. If you want the faster hub 6 Sky will supply one if you buy their WiFi Max package.

@thepostie

Perhaps also worth remembering that having a gigafast connection into a property has the potential to provide numerous devices with 'enough' bandwidth when in simultaneous use: very few individual use cases actually need extremely high speed by themselves.

Video streaming, for example, doesn't benefit at all from having anything over about 30Mbs available for the stream in question.
