An EVG reader, who works from home, shared this (including the above photo) about the Fire TV Stick...
My web connection really slowed down. Once I got on my Verizon wireless modem setting online with one of their tech people, it turned out that along with my devices listed as connected there was also an Amazon device connected. I do not have an Amazon wireless device. Turns out it is an Amazon Firestick, the device you connect to a TV to get Amazon streaming video.
Verizon said that there are apps for phones now that can be used to figure out your wireless passwords easily. It is commonly done with Amazon Firesticks since they take a lot of bandwidth. Once I changed my password and wireless network name the device was no longer listed as connected. The tech said she changed her wireless name and password every other month due to this.
The reader shared this because it "may save a lot of people aggravation."
