Wifi drops from 450mb -> 0.8mb just from walking down the hallway - eviltoast

So ive got a router (G3100) by Verizon in Northern VA. 3 level townhouse. The router is downstairs in the basement.

In one room (top level) , above the router i get 450mb down with 0 connection issues. To a PC. Theres an E3200 up there to boost it.

If i literally walk down the hallway into the next room, it drops down to 0.8mb and the connection constantly drops (PC, AX200 card). My Steam downloads speeds drop down to 8kb/s and at most i get 6mb/s. Its incredibly frustrating.

I understand Wifi gets slower the further you get away, but this amount of drop does not sound normal. Im literally less than 25 feet from the point i get 450 down. Is this normal or is there another potential issue?
