If you Just got recently got the cable television through ATT IPTV Uverse. ATT installer was scheduled to arrive between 12 noon and 4:00 pm on Wednesday. Before the date of installation, You Can do some research to see if ATT could use the phone line or coaxial cable to share in some way I could keep the connection from Comcast, in addition to ATT TV. DSLReports was a big help in your research, your google-fu was not able to get a definitive answer as to whether RJ-11 would be enough bandwidth for ATT IPTV Uverse.
At the time of installation, the technician was submitted in time for lunch. Television showed him and informed him that it would not be able to use the coaxial cable as needed to keep the Comcast internet connection, so you'd have to use the phone (RJ-11) connection for the TV installation Uverse. Because of this, there was a small inconvenience that no RJ-11 connectors in the room, just in the kitchen and the bedroom (although I was not aware of the one in the bedroom until the type of ATT is.
Instead of running a cable through the lobby floor in the kitchen telephone, the technician found a RJ-11 jack in the room that you could use. After a bit of the test was able to determine that the cat in the room would be suitable for installation and connect the phone to the wall in the room, ran across the motherboard, and in the closet where a discreet hole was drilled just above the base plate in the living room behind the TV. Then went downstairs to get the AT & T and then proceeded to connect the modem, ATT calls its residential gateway. Then connect the DVR to the RG via Ethernet, and TV decoder via HDMI. The router connects to the root of a drive backup battery Belkin.
After that then waited 10 minutes or so it took the DVR to download a firmware update, and during this time was more than our particular plan, the remote control and how to restore the system in case something went wrong. When the set top box (STB) started we were able to access the guide in all our channels. Then he demonstrated the DVR functionality, the program guide, and different menus.
Overall you will had a positive experience with the installation itself, and the ATT technician, who was helpful and diligent.
