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.
