Mesh WiFi coverage in larger rigs

Larger rigs (especially with slides and multiple rooms) often have real WiFi dead zones from a single router, and a mesh system with a couple of nodes solves this far more reliably than just cranking up router power, which has diminishing returns and can cause its own interference issues. Placement matters more than the specific mesh brand — keep nodes with line of sight where possible rather than behind cabinets or appliances.
