Apologies if this is a dumb question?
I have BT ultrafast fibre plus 2 and get 306Mb/52Mb Download/Upload respectively from my hub to the isp.
However, when testing “speed to this device” in the app I get only ~165Mb when connected via my whole home Wi-fi setup. I know Wi-fi normally drops around 10% or so but this is a much bigger difference and interestingly when I connect to the smart hub’s Wi-fi directly I get around 250Mb’s.
Any suggestions to why there is such a huge difference? Thanks
Hi, so the master disk is getting around 90% of the hub speed at ~260Mbps on average.
I then have 4 other discs all with connections rated excellent at around -53 to -70 connected via the Wi-fi backhaul directly to the master disc, when connecting directly to each disc via Ethernet I am only getting around 150Mbps which is ~50% my hub speed?
Hi, thanks for the reply but I am not sure how it will help?
The discs aren’t dropping out, they just aren’t as quick as I believed they were going to be and I wondered if this was by design or an issue?
Regarding the firmware update: I am not sure how this will help, has their been a known bug and fix release or something?
Note: I have the latest build
The first disc (connected by ethernet) should see the same speed as your router, but the speeds the other discs get will not be as fast and will depend on their environment. Whole-Home Wi-Fi is a dual-band product, meaning that the “backhaul” Wi-Fi connection between each disc is shared with devices. This means devices connected to the discs can see a reduced bandwidth compared to the first disc.
If absolute maximum speed is the priority on the discs, then you could consider linking the discs back to the router with an Ethernet cable if that’s practical. You will still get the benefit of the Whole Home Wi-Fi system for devices but may lose the flexibility of Wi-Fi connection to your more remote discs.
I hope this helps?
Thanks for the help but this isn’t an issue with the Disc to Disc speed.
I have been doing further investigation by plugging in to the Ethernet of each disc that has a Wi-Fi back haul to the main disc and found speeds very close to my hub speed of 300mb.
However if I connect via Wi-fi to these discs and test the speed they are performing at roughly half the Wi-fi speed of ~150mb which is very odd as when I connect these same devices to my Master Disc they perform at nearly my hub speed again.
My conclusion is that the Discs are topping out at providing both a high speed Wi-Fi backhaul and Wi-Fi access connections as connecting to the Ethernet port for access reduces the bottleneck significantly more than expected if it was a Disc to Disc connection speed issue?
To add to what @Matt-S said in his post, you are seeing this because the 1st generation Whole Home Wi-Fi discs share the same Wi-Fi radio for backbone connection to other discs and with clients, which causes the 'repeater effect' and halves the available bandwidth. I would expect if an Ethernet client gets 300Mbps, a Wi-Fi client would achieve no more than 150Mbps.
You should move the discs slightly closer together or connect via Ethernet to increase the speeds. You may struggle to get the maximum speed of your Ultrafast line to a single client with the 1st generation Whole Home Wi-Fi but can easily distribute to multiple clients streaming simultaneously across the home.
