Don't know how you are arranged, but basically you setup the repeater between your current wireless router and the remote location. The most obvious spot would be the nearest point in your house to the trailer, maybe even in the attic if the temp extremes work for the repeater. Might even work from a garage or outbuilding that splits the distance and might even find ones made for exterior use.

Mine is a Linksys AC 1200, but Netgear and D-link are comparable. The setup on mine has a light that let's you know if the placement from the base is okay and then you log into the repeater with a computer/mobile device to setup a name and password for it. The repeater only needs an outlet to plug into, no other wiring is necessary. You can find some that plug right into the wall outlet, but not sure how well they perform from such a restricted location as you've mentioned that on top of the lamp works best with your current router.

Unless your current router is about as close to the trailer as any other point in the house, a repeater will dramatically improve the performance.
