Hi there, sorry I'm not sure it this is a particularly relevant question regarding the router rather than general electrical safety query but I thought I'd ask anyway with people having a lot more experience with the One Hub and power supply potential issue. Had the router for about a month and was doing some testing using it as a modem only with some deco units and when I unplugged the One Hub there was an orange flash from the unit at the power connector. Stupidly, I admit that I didn't notice the power button and so unplugged it when it was on (oops). Plugged it bag in and out a couple of times and no further spark. Obviously from now on would use the power button before unplugging but would this be any cause of concern?
Many thanks for taking the time to read this, Simon
