Starlink in house, wifi to trailer in back yard
To begin with, I have no experience with extending wifi so have been researching for the past week, enough to become more confused about the appropriate solution.
We recently installed the square dish Starlink system in the house and have good wifi out here in the sticks, where fiber is rumored to be at least two years away, and Spectrum wants $10k to run a line to the property. The modem is in the living room at front of house and wifi is fine in all rooms. When within 30' of the house (60' from Starlink modem) wifi is good in the back yard. At 60' (beside the trailer we need good wifi to) wifi is degraded, yet still most times workable. However, when within the aluminum trailer itself, NO wifi signal is available.
The (aluminum framed and sheeted, insulated, with 1/2" plywood interior walls trailer is set up as a recording space. We've been using a wifi hotspot in the trailer, but wifi is often slow. We want to share the Starlink wifi from the house. Trailer is 90' overall from modem, and there are two woodsheds between rear of house and trailer, but with direct line of site between sheds to rear window of house.
Hoping for the best speed in recording room and better reception when outside in rear yard. At present, with only four total wifi devices connected, the need for prioritizing any of these is unnessary.
My first thought was to install a couple Ubiquiti nanobeam type directional devices, one at rear of house, the other on the trailer, but near as I can make out, this would also require adding another router at the trailer (and perhaps other hardware?), and might also cause interference between the Starlink and trailer signals when outside between the two?
I next considered adding a pair of Deco X90's to create a mesh system. One would be inside at rear window of house, the other inside trailer. I thought, if this would work, no additional router would be necessary in the trailer, and roaming around the rear yard would be handled seemlessly by the mesh system. Unsure whether signal would be strong enough between the two X90's in this case, and reading the setup instructions to connect to the Starlink modem (should I be calling that a router?) I see setup requires connecting the Starlink by ethernet cable (after purchasing the requires Starlink ethernet adapter) to the first X90. What I don't understand is if that first X90 would then have to remain connected by ethernet cable, or if, after linking, if it could be moved to rear house window and would then work wirelessly?
Another thought is, IF primary Deco must remain connected by cable when located by the rear window, this would require that I do some crawling under the house to run the line. If so..., as an alternative, perhaps I could just buy ONE Deco (if possible) and a 100' direct burial Ehternet cable and run it from Starlink modem all the way to inside the trailer to the Echo. Seems that, wired into the trailer would provide fastest speeds, and Echo inside trailer would also improve rear yard signal. Seems...., but, with little understanding at this stage, no clue if correct. Alternatively, if buying two Echos is required for the mesh system, would it work to run ethernet cable to the one in the trailer permanently?
I don't mind buying premium hardware to achieve the goal, but wish to avoid buying more than necessary, and/or adding unneeded complexity to the system.
