Just a quick follow-up to close this thread. The solution proposed by @plemans worked! The page now reads: "Cable Connection Status: Good" in green. Also, no warnings or criticals in the event log since January 26th, when the splitter was installed. No more connection issues either. Everything has been rock-solid since then.

Power ranges from 5.1 to 7.0 dBmV now. SNR very stable from 38.9 to 40.3. I am also attaching a screenshot the tech gave me which shows the "Flux" since I don't see that listed anywhere.
Thank you both so much for your help with troubleshooting my issue. It is greatly appreciated.
