Confusing question, Rudy. I think I know what you mean though. A WiFi router (and others, I might add) such as this IS the hub to the internet via your cable or phone connection, ISP. This and other models can connect to your computer either through an RJ-45 network cable and/or WiFi signal (if your computer/phone(s)) are so equipped. Most computers have the RJ-45 jack (and maybe a wireless adapter, too) to connect. Laptops TEND to have wireless built-in these days and probably an RJ-45, too. Smartphone tend to just have wireless features. So to simplify, This modem has ample connections for whatever device you probably have unless it's over 10 years old or so. But--to be quite honest--there are cheaper routers out there that will do the job for you. This one has advanced features for people who like to tinker with settings to squeeze out more bandwidth for certain tasks. It is a fine piece of equipment, nonetheless, but based on your question, it may be overkill if you haven't a clue what those features mean.

Actually it doesn't. It has a USB port. And you could add a Bluetooth adapter along with BT headphones, I guess.
