I have BT Whole home wifi (Smart Hub2 + 3 Whole Home wifi discs). It works perfectly for everything except Facetime on an iPhone (XR and SE2).
Speed tests come back as expected (63Mbps Down, 17.5Mbps Up), jitter = 1ms, and ping 14ms.
This is the same whatever disc I am on, I can walk between the discs, they all are with Good Connection and 5Ghz band.
The wifi on the smart hub is turned off to avoid conflict.
But when we use facetime to someone else, it can (not always) be jittery, broken or plain unusable. Yet I can run a speed test and get those figures above!
I've turned off Band Steering on the discs, but left AP Steering on. I've checked the 2.4 & 5Ghz bands are relatively clear. And it doesn't seem to matter what time of day or night it is either.
Any advice please?
Have you tried switching the whole-home system off and the hub Wi-Fi back on? that should enable you to identify which of the two (if either) is letting you down
Definitely the Hub or Broadband.
Over the last few days, I've connected to the hub directly by using its Wifi. The same results, drop out, more so the sending picture/voice, as they cannot often hear or see us, but the received picture is pixelated.
Drop back to 4G (ie turn off the phone`s wifi) and it's perfect. Thus ruling out their end.
We've just watched the whole of the funeral on iPlayer over wifi without a single drop out. So it has to be some sort of conflict with Facetime and the Smart Hub 2/Broadband?
Try re-installing the Facetime app and/or using a different video calling app such as Google Meet to see if it's an app problem
No harm in trying and you won't know until you do
I am at the end here, what else can we do?
I've now had someone round on a brand new iPhone 14 and their facetime was horrendous too. Just kept dropping out, yet again when on their mobile network providor, perfect.
We've streamed HD TV to the BT Vision box and to the TV directly over WIFI without a single glitch or missed frame.
The only option left is a problem with the BT service/Router (as we've ruled out the discs by connecting direct to the router). But if i do speed tests it's perfect too; 66/17Mbps, 15ms ping, 87ms jitter.
Thanks for any further advice.
Have you tried a factory reset of the router, be advised that you should backup your configuration first and restore it when the hub restarts otherwise your discs won't work (assuming they're the black ones, the white ones will work without taking this step)
