Xfinity offers professional installation services for a one-time fee ranging from $60-90.
If you choose to install the internet service yourself, Xfinity will supply a self-install kit that includes a how-to guide, xFi wireless Gateway, and the necessary equipment—a coax cable, Ethernet cable, and a power cord. If you select a TV and internet bundle, you will only have to pay one installation fee, which will depend on the type of bundle you select.
