It's also been mooted here by me that the "yellow light = bad wifi" is a load of old cobblers, and just because somebody at VM has put up a web page saying this doesn't make it so.
Yellow LED displays on Hub 3's are exceptionally rare though with several million Hub 3's in use they do crop up from time to time, and in every single case I've seen in this forum the Hub has been faulty and required replacement. If poor wifi conditions generated a yellow LED, then we'd see it far more often because poor wifi and Hub 3 are synonymous.
I'll flag this for the staff to comment.
