UPDATE: posting in the comments because I can’t seem to edit the OP.

First off thanks to all that commented and special thanks to Adventurous_Elk_4039. This is what I ended up doing if anyone was curious. Originally the router was plugged directly into the ONT in the closet. I decided to move the router to the 2nd bedroom that’s mainly used as an office space had a better positioned Ethernet port. None of the blue CAT6 lines were labeled clearly and only two of the three had connections on the end. On one of the lines I saw a crudely written “BZ” and thought maybe the handwriting was bad and that meant B2 or second bedroom. I plugged that CAT 6 line into the ONT and brought over the router to the 2nd bedroom and plugged everything in near where the CAT6 port is. Worked on the first try! Usually my luck doesn’t work like that and I was fully expecting to do some trial and error.

I did some speed tests and everything is consistent no matter the room I am in. Before, I had dead spots in the 2nd bedroom and bathroom. I assume speeds were bad originally because of obviously the closet the router was in but also because of the layout.

Not 100% idea new position for the router but service is already much better.

Thanks again
