WiFi gets 100+Mbps. Wired Desktop never goes above 100.

So I have a very particular issue. I signed up for Xfinity’s Extreme package and it has been pretty great for providing me fast and powerful internet speeds.

However, my desktop, or anything wired from my office, Can’t get anything above 100Mbps.
What’s even weirder is that every cable run into my office is Cat 5e and the Network Status quotes that it’s speed is at 1.0 Gbps. I’m completely stumped.

EDIT: I’m highly thinking these wall mount boxes are the problem. The modem/router,switch, and pc are rated for Gigabit. All cables are 5e… Then there’s these ugly boxes https://imgur.com/a/PuIKluy

EDIT 2:
The pathing is as follows
You’re gonna hate this… lol

Modem/Router = wire = wall jack splitter = wire = wall jack splitter = wire = switch(confirmed 10/100/1000) = wire = PC back I/O

EDIT 3: so these are the cables actually being used.https://imgur.com/a/kKTWddI

Gateway is Comcast’s xFi Advanced Gateway (TH3482G)

EDIT 4: I bought a cat 6 wall jack and rewired it watching a YouTube video. I now have my true speeds in my office now! Thanks a ton everyone!
