A few weeks ago we came home and the Roku thought we had changed its location, now we get Chicago channels instead of the Denver channels. I cannot find a way to fix this.
What channel/app are you using to get these channels? Some channels/apps have a setting for your location, but most ascertain your location via your IP address. Try one of the geolocation websites like https://www.iplocation.net/ to see where your IP address is indicating you're located.
