Signal boost

[Bassman39]

I have an ARRIS ROUTER TG1682G in a house. 120 feet away is my 5th wheel trailer. I get very weak service in the trailer.  I am looking for some way to increase the signal.  Booster??,  wifi extender??.

There is no place to plug ANTENNA into ROUTER..

I get a little better signal, when sitting by a window in direct line with house.

Any ideas??

A wifi repeater will take one wifi signal and pass it on to remote devices. But 150 feet might be pushing it.
