Slow connection speeds

[NIGHTSTALKER_8_4]

I’m at a loss, I have gigabit internet that works great on everything except my Desktop

RYZEN 7 5800X3D

ROG CROSSHAIR VIII HERO WI-FI MB

Windows 11

When I run speed test it starts out fast 200Mbps for a Second then drops down to 20 the 15Mbps and finshes Finishes 15-18Mbps

thats on Wi-Fi and with Ethernet (I uninstalled and reinstalled drivers with no luck)

So I thought maybe it’s the internal Wi-Fi and Ethernet on MB so I installed a new Wi-Fi 6e adapter i disconnected internal Wi-Fi and installed new PCIe adapter and still same results. Not sure where to go from here I’m stumped

it should be an option on your router called QOS or adaptive QOS,

it usually prioritizes connections over the other for latency and connection efficiency,

 

I had a similar problem with this issue you're describing that ended up being the ethernet WAN cable being broken in several areas from my room to the host modem.

 

ethernet cables usually default to lower speeds when broken in case of fire hazards to the cable being exposed. try swapping it.
