I recently joined Comcast. I spent my whole day off going to 2 different xfinity stores to get my needed equipment to do the self install. I just moved into a new apartment and have about 6 different cable outlets. NONE OF THEM WORK APPARENTLY. I tried to hook up my equipment and only my modem works. No cable boxes worked. I called support and was told the outlets were inactive and a tech would need to come out. And u have to pay 70 buck for it... Excuse me? Why am I paying when I have perfectly good outlets? I have a child that does virtual school and I need my service and it isn't my fault the outlets aren't "active". I also bought a new TV today and had I known this would happen I would not have done so. I'm so upset and since I have 30 days to cancel I think I will explore my other options. I'm so upset over this and am completely disappointed <Edited>
There are some requirements that you must meet in order for a self-install to actually work correctly.
Self-Install Kit Eligibility
Are you (or someone in your home) comfortable connecting a DVD player or connecting to a wireless network in your home? If so, you probably have all the technical skill necessary to install and activate Xfinity service. But there are a couple of requirements we want you to know before ordering your Self-Install Kit.
Xfinity TV Self-Install Requirements
The coaxial cable included in your Self-Install Kit is six feet in length, so the outlet in your home must be within six feet of where you would like to place your TV Box.
Xfinity Internet Self-Install Requirements
The coaxial cable included in your Self-Install Kit is 15 feet long, so the outlet in your home must be within 15 feet of where you would like to connect your modem.
Xfinity Voice Self-Install Requirements
For moreinformaiton about SIK eligibility you can read this document: https://www.xfinity.com/support/articles/self-install-product-availability-and-eligibility
If you do meet all the requirements for general self-install kits and for each line of business you are wishing to receive then I would wait to see what an employee says or contact them via the methods outlined here for immediate assistance.
If you do not meet all the requirements listed above you must have a tech out to do a professional installation.
Hope this helps.
