How can I get my local channels changed from Columbia mo to KC Mo

Need more information:

• Are you picking these channels up off the air with an antenna and viewing on a Roku TV after having the TV scan for channels, but getting guide information from a different area?
  
  
• Instead, are you viewing local channels by streaming them to an app on your Roku?  If so, what app are you using to view them?  It is that app that determines which local channels they provide to you. 
     
  Some channel apps determine your location by the IP number assigned to you by your internet provider. If your internet provider assigns or changes your IP number to one attached to one of its servers located in a different area, that could change the local stations you are provided.
     
  You can use an IP info website like the ones listed below to see where the IP number assigned by your internet provider indicates you are located. If this doesn't represent your actual area, you can contact your internet provider and ask to be reassigned an IP in your area.
  
  I'd suggest you try several of these, as their results do vary, and you never know what the channel's location check is using to determine your location.

  A web search for "IP Location" can find many more.
