I’m connecting to the I-net via Verizon FIOS using their router, which does have wireless capability but my computer is connected via a physical line. But, I can plug the Kindle into a USB port on my computer and download via this connection. Is that correct?
If the wireless is turned on and you have a password to the router, your kindle would connect thru the wireless router directly via “wifi”. You can’t connect directly via a wire to to the computer. Now what you can do is get a ether net to wireless adaptor which would connect to one of the other router ports and creat an instant wifi hotspot. Your Kindle connects to the wireless adaptor which connects to the router via wire so you can get away from having to know the main router’s wireless access codes.

It is a pretty cool router, actually. You can upgrade it to an industrial-strength router with open source DD-WRT firmware.
You'll probably spend half that much just getting the cable you need to hard-wire it to your PC.
Wired is faster, which is why your PC is connected that way.
Since you already have a WiFi router, you are in business. It shouldn't take that long to figure out how to connect once you have the Kindle.
I have the Kindle Keyboard and when I bought it, it included a USB cable (along with a wall adapter, and auto adapter) so you can download directly from a computer if you need to. That USB cable also plugged into an adapter that plugged into a regular wall socket for charging. I noticed that the types of charging cables offered are said to be different so you just want to make sure you check to see you are getting the cables you need. I use WiFi most of the time but had to use the USB when my Kindle software wouldn’t update automatically.
