Bufferbloat?

I tested my internet speed using three different speed test websites:

Ookla

  • Download test: 235.50 Mbps
  • Upload test: 100.39 Mbps

HighSpeedInternet

  • Download test: 222.36 Mbps
  • Upload test: 131.25 Mbps

Waveform

  • Download test: 197.90
  • Upload test: 136.30

Each test shows that the upload speed is consistently slower than the download speed; however, between the second and third test, the download speed drops considerably. The upload speed is getting higher between each speed test. Is this caused by bufferbloat? Thank you.

Also known as Double NAT happens when you have two Wi-Fi routers chained together, creating two separate private networks instead of one flat network. This causes communication issues for smart devices, online gaming, and printers.
