I'm running DD-WRT v3.0-r41686 std (12/10/19) on my Linksys WRT1900ACS. When I plug directly into any of the lan ports and run a speedtest from the laptop directly to the router I only get about 11MB/s. I've tried all ports and multiple different cables.
Am I missing some setting in DDWRT or is this a bug in the build I'm running?
Btw this is the command I'm running for the speedtest

A better test would be to use iperf. FWIW, I averaged about 5.22MB/s from a dinosaur 13" macbook running Debian 10 to my R7000 running FreshTomato. I don't see how you're connected at 100MB/s unless there is an issue with the cable, or the NIC is configured for that speed, etc., or the NIC is not gigabit. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

I'm not concerned with the test. Using the same command I'm able to get 100MB/s from machine to machine. It's not a problem with the nic on the laptop. It's capable of 100MB/s and has been tested. The LAN port on the router IS 100MB/s.

Yes, a router is a PC. Most definitely. Yes, I am being sarcastic. I presume your machine NICs are 100MB/s fast ethernet and not gigabit. That junk macbook is gigabit. FWIW, average for the same test on my E4200v1 running the latest public beta of DD-WRT was around 850-900KB/s. I still suggest to try setting up an iperf client or server on the router or a machine and then client on the other and test throughput that way for giggles. You have nothing to lose. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

It is very clearly an issue with DDWRT.
the test is shit
in the best case, this is used to measure the ssh / scp transfer speed and nothing else

i'm not sure if you understand it but the test is "bullshit" so you measure the ssh transmission rate
what are you doing over ssh? any permanent tunnels running?
as I said, you can measure the real transfer rate between two devices with iperf3
I won't go into the worse ssh performance now, but ssh is encrypted and is usually only used for administration
I already have measured transfer rates that's what lead me to also try the ssh test. I've done file transfers from computer to computer and router to computer both wired and over WiFi
I won't be able to do this for another 12 hours and I'd rather have us look into other issues in the mean time. Not only have I ran multiple different tests using different methods I've proven that there's nothing wrong with the SSH test. But the most important thing is this argument couldn't be farther from relevant
If you can't get off this topic just stop posting. You're being incredibly unhelpful
