Try unsyncing the 2.4 and 5G bands if the router is dual band, and giving the 5Ghz band a different name to the second (adding a 5 should suffice). If that doesn't work try giving them a static IP...
It maybe that you don't have a dual band router then, could you please let us know which hub you have. TIA 🙂
The BT Whole Home is a mesh system and does not allow the 2.4 Ghz and 5Ghz bands to have a different SSID so this is a non starter.
Can you see the devices in the App or on the Web login and if so do the IP addresses check ?
A bit more info ... I had a Samsung S6 Edge phone and a Galaxy Tab A connected to my Whole Home network.
The tablet went offline, though it still had an IP address (192.168.0.24) so I quickly checked to see if this matched the IP address it was assigned on the router using my phone. Turns out it had gone offline at the same time !
When in this state, the phone shows "Authentication error occurred" on the wifi screen. In both devices, switching wifi off and on restores the connection and the devices get the same IP addresses as they had before going into limbo.
The same problem happens on an Amazon Fire HD.
Have you tried just forgetting the Whole Home SSID and re-adding it? May need to create a new profile after the update.
Do you mean just forgetting the network on each device, then re-adding the network ?
Hmm, no I don't think I've tried that, I'll give it a go and see 🙂
Are you still having issues with these devices and seeing an authentication error after forgetting and re-adding the network in your phones?
