I've used in past to connect through a neighbor's shared wifi that's 100 feet away in his home, and then through his window into my closed window and still get 56 MB/sec. He's moved over to using only verizon phone connection and now I'm using an xfinity hotspot, but at double broadcast of 99db, but it's 5 blocks away from me. My speed with that is 26MB/sec currently.
In my detached garage I have a desktop that has a place to connect a wifi antenna. I have wifi in my house and sometimes if I’m at the opposite end of the garage that my desktop is on I can get a one bar signal on my laptop. I cannot move the desktop as I use it to control my CNC. I was wondering if I could get some kind of connector with a cable, run it from the desktop to outside the garage, and aim an antenna at the house if I could get a much better signal? If so what all would I need for this and since I don’t need the internet that often Id really like to keep this low budget. Also as an alternative I can use my phone as a hotspot but only while it’s plugged into the the desktop. At that part of the garage I have 1 bar of LTE, but outside I have 3 bars of LTE so if there’s something I could rig up to increase the signal strength on my iPhone while in the garage I’d be open to that as well. Thanks.
