I have an old installation with a slimline dish going to a SWM-8 and then an 8 port green label splitter with a power inverter. I have two HR24 and a DECA ethernet adapter connected to it. Used to have HR20s so needed the additional ports. During the last few months, I started to get transponders going to zero and back up to mid-90s after a few seconds. Sending a refresh signal and a reboot took care of it, except it would happen again after a month or so. AT&T online sees the receivers as offline, even though they are online. Tonight, both receivers went dark and got 775 messages. Rebooting did nothing and could not send a reset signal cause I could not log in (apparently servers went down is what I was told when trying to reset passwords even though that wasn't it). Power Cycled the power inserter (even though it was green) and was back up. D* wanted to do a truck roll for $20 but refused. I'm not on contract and very close to jump to YTV and Sling (for Spanish tier - I have an old Option package). Not doing any protection plan nor extending contract. Besides the dish which is old but still works, what should I replace? Power inserter? SWM-8? Splitter? (I do have a 4 port splitter that I could replace it with).
