There isn't any included in the Amazon firmware that I know of.
And you would have to have our jail break installed to run code of your own choice.
You are now using 5.8.9.2, for which there is no available jail break.
I think you are fast approaching the point where your only option is to return it for exchange as a defective device.
How did your out-of-case trial go?
Anything found yet that makes a difference?

Sorry, I have forgotten what country you are in, and the details of the following varies by country ....
All Wifi Access Points (APs) ship set to channel 6.
Meaning that without changing it, yours is operating where there is the most likely chance of interference from other Wifi APs.
When you access your Wifi base station to check the logs and to reset it, also go into the setup and change what channel it broadcasts on.
It might be that your Kindle is not as good at working in a high interference situation as your other, larger (and larger antenna) devices are.
Here is an article with pictures:

And if you scroll down, there is a Linux command to find out how congested each channel is (I had forgotten about it), which is a direct answer to your question.
(Your Kindle runs Linux.)
But even so, you have to have your Kindle jail broken to access the command line.
Edit:
I just checked, that utility is included in the Amazon firmware, and it does work as shown in the article above.
Still you need access to the command line, which requires at least our jail break plus the installation of our kTerm (Kindle terminal application).
Which is how I just ran it on my KT3.
Here is an example of the information you see output from that command (just one of my neighbor's - mine is off):

Of interest in addition to just a count of the number of users on a channel is the line:
Code:
Quality=29/70 Signal level=-81 dBm
I.E: How much interference and how strong the signal is, as seen by the Kindle.
