This summer we build a detached garage in the process Xfinity/Comcast came out to hook up service and the Tech told me to just run COAX to my garage to extend my service out to the garage. I have buried the cable and since have found no solution to have a WIFI / Internet signal in my garage. From what I have read I probably should have just buried CAT6 cable but now I am pot committed. Please help.

That said, your options depend on if that coax is attached to the Comcast network. If it is, and it probably is if it was a Comcast tech that did the job, you’ll have to get a second cable modem registered to your account. If the cable terminates in your house, you could get a pair of ethernet over coax adapters. You’ll still have to worry about getting ethernet to the cable’s house end and a WiFi bridge for the cable’s garage, so I hope your garage is powered.
Alternatively, you could ignore the cable and go with a pair of directional WiFi antennas with their associated hardware.
