Well, I'm not sure Intel can answer either, but I'll give it a try...
Not knowing anything about your setup, does it look something like this?
Kindle ==(wireless)== Samsung laptop ==(physical cable)== wall socket
If you have no router, what does your laptop talk to, to get internet?
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.
