Yes, that's the setup.
The Kindle recognizes the network created by My WiFi by name.
It gives a list of networks it can "see", and I can tell from My WFi's Properties that it has the right one. I changed the password to make certain the one entered was correct (the original failed), but that made no difference.
I also tried changing to a DHCS connection when the original didn't work (making a note of the original entries for IP address and Subnet mask; the other two lines were blank), but that didn't help either.
I'm probably only missing something.
Thanks for your concern.
