I have ordered internet service from Xfinity to be installed (I have an appointment) at my home in a few days. I have an approved cable modem that the installers will be using. I currently have AT&T internet service with Uverse TV right now that runs through the DSL modem. There is NO connection whatsoever to any coaxial cable. My TV receives its signals strictly through Wi-Fi.
My situation is this. I connected my cable modem to an open /available coaxial cable (in the distribution hub of my home) and connected my laptop to the modem. I wanted to activate my Xfinity cable modem and see if I could start my new internet service online. To my surprise, I was able to get on the internet. I tried to activate the cable modem. However, I received a message online saying I had to call a telephone number to turn on the line. I didn’t go any further because I was afraid of messing things up.
I am a little confused with this because my internet connection is through the DSL modem that is fed from a telephone line and there is no connection to any coaxial cable(s) in the house. Therefore, I should not get any internet connection from the coaxial side?
My question is… Do I need to cancel my AT&T internet service BEFORE I start my Xfinity internet service? Or can the service people hook up my internet service first? And once that is done, then I can cancel my AT&T service afterwards?
Alternatively: Should I completely disconnect my DSL modem, hook up the cable modem to the available coaxial line and try to activate the line by calling Xfinity to activate the service?
