Adding wifi in an outbuilding
I apologize if this isn't the right forum for this, I didn't see anyplace else it really fit.
I bought a 1.6 acre piece of property last fall, the house is middle/front and my outbuilding (a large pole barn) is near the back. I have Comcast cable for TV & internet, and an Asus router for my wifi.
There is a cable that goes from the house all the way out to the barn. It is approximately 140 ft. from where it connects in the house to the barn, then another 50 ft. inside the barn to the cable box I have. So, a long run.
I am able to watch all of my HD channels in the barn, so far without issue. I don't watch it a lot out there, but enough to be pretty confident that everything is okay.
However, the wifi signal out there is extremely weak/non-existent. My grand plan is to work on cars out there, meaning a laptop with internet access is extremely handy. Plus, I'm adding heat and would love to have a wifi-enabled thermostat so I can turn the heat on from in the house before I go out there.
What is the best way for me to get wifi out there?
