When watching Netflix via my Apple TV the movie just stops and freezes. I noticed in the settings for Apple TV the signal strength will go to nothing then back to 3 or 4 out of 5. It doesn't do this all the time. Would purchasing a Wi-Fi booster/extender correct this issue and if so any type better than others. My router in behind a plastic door in a storage closest that also has a door, and to add to that the room where my Apple TV is has a door. The router cannot be moved the way it is setup and wired in the newly built apart. See link for some extenders that I could get at a local store. How easy is it to set them up? Is it just a matter of plugging it in and it links to my system? Thanks for any info or suggestions with this. https://www.bestbuy.ca/en-ca/category/range-extenders-powerline-networking/32220.aspx Here is my current equipment setup: (1) ARRIS Touchstone TG2472 Modem provided by Cocego Cable - this is of course for our cable tv and also provides phone and internet. (2) Airport Express is plugged into the Modem above. My macbook works fine but it seems to be a signal issue in the other room when watching Apple TV.
