First up I should state that I have reported the issue posted below to EE Customer Services, but I thought it worthwhile posting here in case others are searching.
I have a new service connected (1.6gbps service) with a Smart Hub Pro and multiple Smart Wifi Pros. I thankfully have an ethernet network plumbed in, so all the Smart Wifi Pros are connected via ethernet directly back into the Smart Hub Pro.
What I have noticed is that if you connect an Apple TV to the Smart Hub Pro via the second ethernet socket on the Smart Hub Pro, you will experience connectivity issues and speed issues (speeds drop down to 100-150mbps when measured using the SpeedTest app). Connectivity issues range from apple authentication issues to a few other odd gremlins. If I place a switch inbetween the Smart Hub Pro and the Apple TV, the speeds go back up to maximum (1gbps), and the connectivity issues disappear, so the software/firmware issue seems to be directly correlated to having the Apple TV directly connected to the Smart Wifi Pro using ethernet.
I have been able to replicate the issue with multiple Apple TVs and multiple Smart Hub Pros, so the issue definitely seems to be a software/firmware related issue - it is not a hardware issue. Plugging an Apple TV directly into the router (Smart Hub Pro) does not exhibit the issue, so it is only via the extenders.
Hopefully the issue will be fixed in a future update, although it does make me wonder whether any other devices experience issues when connected to the Smart Wifi Pro via the ethernet socket.
