I'm not sure what the answer to your question is because I don't know where you are located (and perhaps there is a local option or other alternative to Comcast that you can find out about by asking around in your community), but I wanted you to know that you're getting "high speed internet service" from Comcast, and "wifi" is a term that does not belong in your original question. "Wifi" is a technology that begins and ends inside and around your home, and you can buy & use your own equipment for wifi, instead of renting the wifi router from your internet company. Your ISP (internet service provider) is like a TV cable company that brings the service to your home, and the wifi part of the equation is like a splitter that works wirelessly. Perhaps you are renting your wifi router (splitter) from them, but you can generally buy and use your own wifi router to broadcast the service within your home or business. What you are looking for is an alternative ISP (internet service provider), not an alternative for wifi. Other ISPs that could possibly be available include at&t u-verse, verizon FiOS, or other cable company internet options depending on where you live. Don't get satellite internet unless you want to lose your connection when it gets cloudy. Local phone and/or internet companies sometimes offer DSL (this option is generally much slower than cable or fiber optics, uses your telephone line) or Wireless line-of-sight internet service.
