When using an Internet connection through a cable provider you usually receive your Internet through the same cable as your television programming. However, if you want you can obtain a Wi-Fi connection through the same company. Although many companies now provide these service for free, if your company doesn't, you can either request the additional Wi-Fi connection (at an additional monthly fee) or install your own Wi-Fi router.
Contact your Internet service provider and see how much the service costs (if it does). A wireless router can range around $100, so take that into consideration if you are thinking about connecting your own Wi-Fi.
Set up a day and time frame for when an Internet service technician can stop by and install the Wi-Fi router.
Plug an Ethernet cable into one of the "Out" ports on the Internet modem, then connect the other end into the "Internet" port on the Wi-Fi router. If you have requested the Wi-Fi service through the Internet company the technician takes care of this.
Connect a second Ethernet cable into one of the "Out" ports of the Wi-Fi router and connect it into an Ethernet port on your computer. Look around the Wi-Fi router for an "http" address number. Type this number into the Web browser on your computer. The wireless activation page appears
Type in the default username and password (admin for both), then select the kind of location you are using the Wi-Fi in, change the password, and adjust any other settings you want. Click "OK" and the Wi-Fi activates.
