For cutting precise and clean edges on your woodworking project, you should use a straight router bit with a sharp cutting edge.
You should not need to. It is a local device that should not interfere with the router and not be interfered with by the router.
To effectively use a router to cut materials, you should first secure the material firmly in place. Then, adjust the router's depth and speed settings according to the type of material you are cutting. Use the appropriate router bit for the desired cut and move the router steadily and smoothly along the material to achieve clean and precise cuts. Always wear safety gear, such as goggles and ear protection, when operating a router.
You should be able to use any Cable Router with your Suddenlink service. Keep in mind, that you will need a modem and a router to receive service. Some WiFi devices have both in one unit. You can purchases these devices retail, or Suddenlink leases them as well.
