Wi- Fi enhancers -Yes I'm new to the RV scene

There are several repeater/boosters/antenna that will improve your WiFi reception reliability, but none of them are likely to improve a usually limited park WiFi service speeds enough to accommodate TV streaming, especially when others in the park are also trying to stream. Many parks deliberately limit the available bandwidth per connection in order to allow everyone basic service and minimize bandwidth hogging. Rural parks in particular may not have sufficient bandwidth available at anything close to a reasonable cost to support multiple higher speed users. For that reason, many of us use a cell phone based data service instead for our Internet use, including streaming.
