I use MT3000 (firmware: openwrt-mt3000-4.7.5-op24-0418-1744954708.bin),
root@GL-MT3000:~# tc qdisc add dev wlan0 root netem loss 5%
RTNETLINK answers: No such file or directory
Unable to find sch_netem on the system
I have installed the packages kmod-sched(6.6.69-r1), kmod-sched-core(6.6.69-r1)
How to resolve it?

The firmware seems to be missing the kmod-sched-netem.
Please try installing the Vanilla OpenWRT firmware.

Thanks. Yeah, I have tried to install kmod-sched-netem but it report the error:
Unknown package 'kmod-sched-netem'.
Collected errors:

  • opkg_install_cmd: Cannot install package kmod-sched-netem.
    OK, I try to install the Vanilla OpenWRT firmware but I am concerned that it may burn the device into bricks. Is there a verified link? I can download it. Thanks.
    Sorry, I am a beginner in this field and didn't understand Vanilla OpenWRT correctly just now. I just downloaded pre-built firmware for MT3000 from OpenWRT offical website. But system cannot bootup after the upgrade is completed. Then I install the firemware downloaded from GL.iNet offical website(openwrt-mt3000-4.7.5-op24-0418-1744954708).
