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.


So it is not entirely clear to me what the problem is?

the iperf3 test clearly shows that the transmissionrate is 1Gbit - between your Router and the PC (~941Mbit / ~117 Megabyte per second)

faster not possible

Thank you for the flowers
just wanted to show you that the transfer rate is not 100Mbit

Is 192.168.1.1 the address of your PC?
If that is the address of your router, you have made a speed test from the router to it self.

In the GUI, go to the Switch Config Tab.

The colour show what speed the device is connected with.

Green=1 Gbit
Yellow= 100Mbit
Red=Not connected

swconfig dev switch0 show

Will also print all details about all switch ports.

as far as i understand it is the address of the router

I described the test there

https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1198310#1198310

a "loopback-test" looks different

on router:
[ 5] 0.00-4.00 sec 2.28 GBytes 4.90 Gbits/sec receiver

on PC:
[ 4] 0.00-9.26 sec 88.0 GBytes 81.6 Gbits/sec receiver

Right, in this test the PC is the client (-c) and the router is the server (-s) with reverse (-R) so the server sends data to the client.

Also it's with 12 parallel streams (-P) for 30 seconds (-t).

I notice there's a bidirectional mode too (--bidir). Neat.

yes you can also test without reverse that would be in the constellation the upload from the PC
just thought the download would make more sense
