These are helpful tips, thank you! I tried bridge mode, but speeds went back down just like they do with the standard/non bridge mode on the panoramic wifi. Signal strength levels and splitter setup are here: https://imgur.com/a/EyWmJWd
I'm not sure how to bypass the splitter to try #1 above. The setup is a bit odd, since there is one coax port in the wall of the bedroom, with two wires going into the back of the coax outlet. I am not sure where the various cords lead since I can't see through walls, but one definitely goes the 3rd level of our house. I'm not sure if the main cable signal is coming up from our 1st floor or down from the 3rd floor, but it's likely the former. I tried playing with various configurations of the in/out but couldn't get anything to work except what you see in the image, which is the way it was set up initially upon move-in—the techs upgraded the splitter but didn't change the orientation of any of the cables.
I do think suggestion #1 could be our best bet since we're not using cable for TV at all, only internet. So we don't need to be splitting signals at all. Unfortunately, there isn't an outlet in the walk-in closet we can use but I might need to try connecting the panoramic wifi directly to one of the three cables there and just running the AC power adapter around the corner. That's perhaps what you meant initially by "bypass the splitter" so I may try that next. Thanks again!
