At this time we are living in our 36' 5th wheel trailer with metal sides and are having internet connection problems 1 bar signal, connecting to a router about 120' away when we lived in a motor home with composite sides at 70' away from the router we linked just fine. Right now I am setting on the steps leading up into the bedroom with the entry door open & the screen door closed & getting a full 5 bar signal. Everyone I've talked to so far says get a signal booster. So to describe what I know I'll equate the 1 signal bar to a tennis ball not getting through the metal siding & if I get a basket ball this is going to get me 5 bars inside the metal box?

Help I need to be able to connect hopefully wireless.

Thanks
