Ethernet wall jack bottlenecking speeds?

So we recently bought a house. It was built in 2004. The house has ethernet in every room, and they all drop down to a closet on the first floor with male cable ends where they connect to my router. Verizon installed a new fiber outside and a new terminal in the garage, and the terminal feeds the closet via ethernet. We have the 150/150 Fios package.

Speeds to the router are 150/150.
Speeds from the router to the various wall jacks are 100/100.
Speeds from router to PC are 150/150 (bypassing wall jacks with a cable across the floor)

I suspect either the wall jacks are limiting the speeds, or the length of the cables in the walls is too long to support over 100mb/s? Any ideas would be greatly appreciated!

The LAN speed tests confirm that "something" is limiting the speed of the in-wall cables to less than 100 Mbps. I suggested the LAN speed test just to rule out some internet speed issue over the in-wall cables.

I guess the next step is to wait for your cable tester to arrive and test the in-wall cables. I would bet on some of the wires not making good contact. Although that would be unlikely on ALL of the in-wall cables, unless you are just unlucky.

You were right about the contact issue. The tester showed several missing connections. I re-terminated both ends using 568B and the tester showed 8/8 connections. Verified speeds and I'm now getting even higher speeds than my internet package advertises. Thank you for the help!

Great! Whoever did the wiring in the first place probably didn't do any testing. Or if they did, perhaps some of the wires were barely making contact, and over time came loose.
