What I did may be an option for you . My issue was zero signal in my detached two car man cave which is about 80 ' from the house . The man cave has metal siding and a metal roof and the house has a metal roof so a tough environment for wireless WIFI to conquer . But I didn't want to run additional hard lines out to the garage . I went to Best Buy and talked with a very knowledgeable guy and he set me up with a Netgear Powerline WIFI booster/repeater . It is Model # PLW1000 and it was $119.99 .
Because the man cave is powered by the home 200 amp circuit breaker box this worked for me . As I understand it this device makes all of your house current wiring a hard wired network . There is a " main unit " that plugs into an outlet near the home router . There is a hard line that goes from the wall unit to the modem/router . Then in the man cave is a 2nd unit that plugs into a wall outlet , that 2nd unit has two small antennas on it . To set up this new network you just follow the instructions and voila you have internet

I have been using this now for over two months and so far it works great ! We have DSL as our internet source and it's not the greatest , but we are able to stream our TV content with no issues in the house and the man cave . Also our cellphones are Google phones which use wifi as the main source for communication then switch to LTE if wifi is not available , so far we have run 100 % on wifi . So I can go out to the man cave and power up the TV and watch a race or football game . At the same time I can scan the internet on my laptop and be on the phone as if I was sitting in my house . I am completely happy with the setup .
