This week I will be getting Xfinity internet service in my home (250mbps). I currently have DIRECTV service from AT&T that uses the coax outlet into my home. I plan to keep this TV service and just get my internet from Comcast. I ordered the self-install kit from Comcast, however, I just realized that Comcast internet comes from the coax outlet already in use at my home. Is there any way I can set up my internet myself or does a Comcast technician have to set it up for me?
