HiGot a strange one, sons kindle for kids does not see our wifi, picks up the rest of the neighbors no problems, just not ours.I have another 7 other devices connected to our wifi without any problem, have reset router, factor restored kindle, still no luck.Can't see why it can't see the wifi when all other devices can.
Are you trying to connect in the Kid's mode?
Perhaps that's a safety feature?
Is this the only Kids Edition you have?

I think older Fires only have 2.4 Ghz wifi, so they won't see wifi networks running on 5 Ghz
