I don't use it for wi-fi as that is taken care of by my Apple Airport devices , and most of my computers are wired by gigabit ethernet . Other than the light showing the wrong colour it is all fine . I did perform a factory reset and after that , on booting up I had lights showing green , amber , red , and settling down to amber ; then after logging into the device via its IP address and putting it into Modem mode , the power light turned red . I'm aware that on one of the later hubs , it is normal for the power light to show red in modem mode . Could one of the recent firmware updates , which I presume my box did on installation , have made this a feature of the Hub3 also now ? Kind regards Re: SuperHub 3 Solid Red Light This is my setup here , plenty of airspace around the hub , and both front and back doors removed from the cabinet . The light , even if it looks orange in the pictures , is solidly red , but the hub is truly not hot to the touch . I'm not using it for wi-fi as that is taken care of by my Apple Airport extreme A1521 ( 6th Gen ) and Time Capsule A1471 ( 5th gen , upstairs ) as well as two Airport express base stations ( for music streaming ) downstairs . Other than the light is red , everything appears to be fine . Re: SuperHub 3 Solid Red Light Mine is the same ; it was only installed yesterday ; was originally showing an orange/yellow light , until I logged in via the IP address and put it into modem mode , after it settled down the light was solid red . The unit is not overheating , is barely perceptibly warm to the touch and everything is working fine ; although installed in my comms cabinet it has 75-100mm free space all around and both front and back doors are removed , so ventilation is not a problem . I have no particular concerns about mine , but will continue to monitor it .
