Significant drop in speed

I just finished setting up my own router, Netgear Nighthawk X8.. And I have gotten a significant drop in my speed.

The test was done on a desktop which was connected via LAN. I am getting 100/100 but I'm signed up for Gigabit. I was getting the gigabit speed with Verizon's Quantum gate router, but with my own router I'm not.. My WIFI signal was strengthened a bit(which I was trying to achieve with my own router, so that's good). I'm not sure what's going on..
