After I installed openwrt, Internet speed down from 500mbits to 100mbits

I need a suggestion for a definitive solution. After I installed the openwrt, speed was bad. I have 500mbit from ISS but I can use 100mbit. What is the problem ? Is there any preferences for this?

Please run test and post the result link at https://www.waveform.com/tools/bufferbloat

  • connected directly where router's wan port is connecting internet (may need to copy MAC address
  • Wired over router
  • If wired is fast then wireless too.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

I taked F from bufferbloat test

Post info, let us discuss it!
Did you get F behind OpenWRT or from your provider?

Before I installed openwrt, Internet speed test was 500mbps and bufferbloat test was "A" with same router. Then I installed the openwrt so speed was down. I have fiber line to GPON then router wan with ethernet cable.

Take a step back, re-read this thread and provide the information requested - we don't even know what device you're talking about, so the past discussion has been guesswork at best.
