"I received one of these from my residential provider. Called to verify and sure enough it was legit. I sent a formal response indicating I took steps to protect the wifi router and that was the end of it."

We have changed our password a couple of times and gotten letters after each change. I am thinking about taking the wi-fi out and running cable only.

Are you using WEP encryption? If so, change it to WPA. WEP is easily cracked, if Youtube videos are any indication.

Did you change your router’s admin password? It is usually something like password.

IIRC, the company that notified you is most likely getting your information from a torjan horse contained within the file that they claimed you downloaded. Every time you run it, it sends a notice to the copyright owner. It is not uncommon for some of these companies to put their own copyrighted work on the PTP networks, with the trojan horse installed, so they can send anyone that downloads it a demand for payment, in some cases up to $2500, with a threat to take you to court if you don’t pay up. Get rid of the file, you will stop getting notices.
