Hello,
I can’t say for how long but the light on my Hub 3.0 is orange. This coincided with difficulty in me keeping a stable 5.0gHz connection as the SSID default to a hexadecimal name.
All my compatible devices would default to 2.4 and I’ve noticed an inconsistency in WiFi speed.
Directly wired I was hitting 360 and wireless I was lucky to hit 10.
