Just got connected to Hyperoptic, so far very impressed.
It appears the HyperHub router is blocking some traffic between the WLAN and LAN connections. For example, when my Apple TV is connected via Ethernet and my MacBook by WiFi, I cannot Airplay to the Apple TV. Connect the MacBook and Apple TV via the same method (both on WLAN or both via LAN) and Airplay works fine. On closer inspection, Bonjour traffic appears to be blocked, thus breaking Airplay.
Has anyone else experienced this with their HyperHub, and is there a resolution?
