Several times a day I lose connection for several minutes. The Ethernet light on my Motorola surfboard will flash like data is being sent but all connected devices will say no internet connection. The issue will resolve after several minutes. Sometimes the downstream and upstream lights will turn off, then flash, them become solid again and the issue will resolve but sometimes it will resolve without that happening.
There’s a coax splitter downstairs that’s powered and plugged in. 5 or so cables are connected. Previous owner maybe had cable boxes in each bedroom but I’m only utilizing the one for my modem. Here’s what my modem is reporting:
Does this look to be in spec? Can I eliminate that splitter if it is causing the issue? Any advice is appreciated.

The amplifier/splitter may be going out or injecting noise. Signals look reasonable, it's just the errors are ugly. If don't need the splitter for anything else, try a clean run just to the modem without it for a test. Take a look at the signals again. Maybe you really don't need the amp.
Check out the connectors while you're at it. Try to get away with as few connectors as possible. Take them apart and shine up that center copper before putting it back together. It usually does nothing, but it can't hurt if they're older and oxidized. Here's a guide on what you should be seeing.
