I have a desktop connected to the internet via a cable modem (Comcast).
Must I use the cable company's hardware or can I buy my own wireless
router. If so would it replace the company's modem or would the router be
commected to the cable modem?
niehaus is totally wrong. You can buy your own modem or router or if you
prefer modem with wireless router built in to it. The only problem you may
have is inputing the MAC addy. You can ask comcast for it. But it woud be
best to look at that slip they gave you when they installed your service.
Also after you have installed your new modem you may want to send the old
modem back as your leasing it from comcast. I think you will save likie 3
or 4 bucks on your bill.
