BT Business Smart Hub 2 lights: what each colour means
10 light states of the BT Business Smart Hub 2, from BT’s own page Smart Hub 2 and 3 Lights Guide. It has one status light, plus a light in the WPS button. This is the hub BT Business supplies, documented on BT Business’s own help pages. BT Business says a newly plugged-in hub takes about four minutes to synchronise, and that solid orange can also mean you have turned the hub into a modem (bridge mode).
