speed test on fast.com, I can't download more than 250 megabytes

Hello everyone,

I have a problem with my network. When I run a speed test on fast.com, I can’t download more than 250 megabytes. When uploading, I usually reach 500 megabytes. Any suggestions on what to check? The network topology is as follows. I’ve already checked the cgnat rules and checked whether there is bandwidth control on the pppoe server. The entire network is at 10gb.

CCR1009 (pppoe server) > CRS305 (L2 switch) > CCR1009 (cgnat edge)

since you don’t provide anything, try to change the cable first

Have you checked any other speed test servers? Like https://speedtest.net or https://speed.cloudflare.com ?

Maybe it’s just the specific server you’re testing against. Fast.com almost always gives me like 5-10mbps when everywhere else shows gigabit. (Netflix limits ipv6 tunnels from hurricane electric sadly)
