Upgrade your modem to a docsis 3 and get a 50 mbs plan from a cable provider. Make sure the modem is supported by the ISP before you buy it. Make sure you are getting a docsis 3 modem, if you buy a plan better than 15mbs otherwise you will be paying for speeds that you will not be getting. You will probably get a better rate through mediacom since they sound like a mid ranged isp. You will also be hard pressed to go over their data plan from looking at their webpage it is 1 TB per month.
