what firmware version are you on now?
here is my complete note on this thread:
I'm using firmware: 4.6.2, release1, from gl-inet
I've installed: luci-app-sqm: git-21.188.55209-f161b40
I've edited the /etc/hotplug.d/iface/96-gleqos file as per instructions
I've set the interface to eth1
I've set both download and upload to 4000
Queue Discipline is set to cake
The startup script includes /etc/init.d/sqm restart
I've rebooted the router after making all these changes.
Update:
I've now disabled the netnat network acceleration.
Now it's shaping up

Why did you set to a so low speed?
Could you set the speed considering 90% of your contracted internet speed?
And then test the before and after?

To confirm it actually works 
Check the speed that you set and the speed that you got on the speed test.
To confirm that it's working, set it according to your contracted internet speed. Something between 80~90%
