Download speed limiting is not working on Ubuntu 24.04.01LTS

[anttihassinen]

I have fresh Ubuntu 24.04.01LTS installed. Quite new laptop.
I want to limit uplink and download speed on ethernet port.

Installed wondershaper by
$ cd bin
$ git clone https://github.com/magnific0/wondershaper.git
$ cd wondershaper
$ sudo make install

I can use commands to affect delay and uplink speed. Cannot control DL speed.
sudo tc qdisc add dev enx607d092de987 root netem delay 10ms rate 10mbit //UL speed and delay is affected
sudo wondershaper -a enx607d092de987 -d 5024 -u 2048 //UL speed is only affected. DL speed is still full power

Any suggestions what to try?
