I had ATT for internet way back in the 90s as part of a promotion through IBM at the time. I also had an ATT land line for a long time. The internet id shows up on deep web occasionally. I have all my credit reports locked.
I used the approach on this website How to install Windows 11 on unsupported hardware - Pureinfotech to install Win11 23H2 on my unsupported desktop and laptop.
Your confusing the 16 tuners of the Hopper 3 with PTAT that records 4 networks on one transponder. You can record 16 different programs simultaneously.
