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

YNaniSK · August 24, 2024, 8:18pm

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

brada4 · August 24, 2024, 9:28pm

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

YNaniSK · August 24, 2024, 11:00pm

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.

YNaniSK · August 24, 2024, 11:06pm

This is device information...

…as well as the exact benchmark/ throughput results, not just 'F'.

Please show bufferbloat result LINKs wired with firewall offload disabled and enabled, then for best case over 5GHz wifi after setting up proper country code.

YNaniSK · October 13, 2024, 3:34pm

I can't connect to 5ghz Wifi on my laptop. I can connect with mobile phone. Is there any problem 5ghz wifi setting? (My laptop support 5ghz)

YNaniSK · October 13, 2024, 3:49pm

Bufferbloat test with Wifi 5GZ on Laptop.

YNaniSK · October 13, 2024, 3:53pm

With ethernet cable (oflfload enabled)

YNaniSK · October 13, 2024, 3:56pm

with cable offload disabled

YNaniSK · October 13, 2024, 4:01pm

Internet speed is normal when offload enabled but bufferbloat is bad.

brada4 · October 13, 2024, 4:10pm

Offload saves the day?

YNaniSK · October 13, 2024, 4:17pm

Not Saves because I installed the openwrt for online games and ping problem. And Internet speed downt to 100mbits again when offload enabled. I can't understand. Are settings true?
