Or order a combo package of internet and tv, but nothing is free. If you already has a cable tv then subscribe internet service will have an add-on cost. Subscribe an internet service alone cost about $50/month after promotion period. Cable tv and online service use same cable but you can only use one modem per subscription. If you want more connection, use a router after modem. Usually, household router has 4 ethernet port, in addition, wireless connection allows you set upto 50 connection.
