Problem with internet speed
Problem with internet speed
The router is quite old, and it doesn't support Wi-Fi 6. It likely only works with Wi-Fi 5.
It seems unusual. I'd consider switching to a different network next.
I saw it clearly! The Killer Network Service for drivers was slowing things down. I disabled it, and instantly everything snapped back to normal speed. After restarting it, it automatically capped itself at 12.5MB/s. I opened the app that manages it and confirmed the limit was set correctly.
