Self Install of Internet and Tv…

Hello all,

Seriously, is it really that easy?  The previous homeowner had comcast installed here.  We went with AT&T.  I find it hard to believe I can just replace existing equipment with theirs have the service turned on and run a couple programs.  Is this really possible?

We also had wireless cable boxes with AT&T.  Will that make it a problem as well?  I’m assuming I only need coax jacks by the tvs for tv install?  The gateway can prolly go in my basement where the AT&T gateway is located.  

What am I missing?  Please share… 

Thanks for your help and feedback!!
