Airport time capsule disrupts internet connection when plugged in to a BTHub6 by ethernet cable
My 2TB Airport Time Capsule (802.11ac) has worked like a dream for several years (it's probably ten years old now), I had it set up as a wifi network and to automatically back up my MacBook Pro. A couple of weeks ago the broadband connection from the BTHub6 dropped out across all devices, the message on attempting to join the BTHub6 connection being 'incorrect password for BTHub6 xxxx'. I got a new hub from BT and disconnected/reconnected every device with the same outcome. Finally, I determined that once the ethernet cable for the Airport Time Capsule was removed from the BTHub6 the internet connection was restored and all was well.......except of course now I am unable to use the Airport Time Capsule. I've tried a soft and hard reset - I am a little wary of going back to factory settings in case anyone here has a work around I can try first. I am using Catalina on my MacBook Pro.
