5 months ago Hi @MizarCs,
to really investigate the problem, you should probably go to the speedtest docker frontend on your pi-hole at port 9798 and have a look at the details there. And based on that, the underlying repo https://github.com/MiguelNdeCarvalho/speedtest-exporter might be a good resource too.
You mentioned Rpi 4, which should do 1 Gbps over the integrated ethernet. So I guess we can exclude potential trouble sources of Ethernet-over-USB dongle or older Raspberry Pi versions, which could introduce a 300 Mbps limit.
If you want to double check the reported speed, you could also test-drive my pull request https://github.com/geerlingguy/internet-pi/pull/475, which runs the speedtest on Cloudflare instead of speedtest.net. Or if you want to keep it simple, just run my underlying docker image and see what results it gives you: https://github.com/martinbrose/cloudflare-speedtest-exporter
Just a few ideas. Happy to help if you need further guidance.
Cheers

It's about a couple of months that my internet-pi is measuring 258Mb/s despite https://www.speedtest.net tells me 786Mb/s: this is a huge difference and I don't know why it's happening. Any advice? Is there a "Docker networking" issue ongoing? My Rpi 4 is connected straight to the router connected via WAN port to the the fiber coupler. TIA
