On the same theme of passwords, I just bought a Sonos speaker and needed it to link to my wifi. So, it requests my wifi password found on the underneath of the router. I have rarely needed to do this, in fact the only time I think was after buying a new TV a few years ago. Anyway, silly me looks at all the lines on the sticker and only ONE states 'Password'. So I enter that in. Incorrect. I did that 4 times. I uninstalled the Sonos App and started again. Nope, still didn't work. Then someting registered in my brain from a few years ago... I entered the 'Wireless key' number. Sure enough, that worked. *sigh*. If you know, you know. If you don't, you follow the instructions to the letter. When that doesn't work, then just try a random number from the sticker!!
