If you don’t want to run a wire to your computer, you can get one of these. The part on the right is the POE injector that comes with your Nanostation or Rocket M2. The part on the left is called an Airgateway. It snaps right onto the POE injector and provides WiFi connectivity so you can connect to the mesh network with any WiFi device like a laptop, smartphone or tablet! They are only $18.10 from Amazon:
