Need help to tune fq_CoDel on a slow ADSL

[Kuzunkhaa]

Hello,
I'm trying to share all my bandwidth evenly to my home with the usage of fq_CoDel, because I want a little boost in games and other live softwares.

The line is in PPPoE (G.DMT) and have a max download speed of 4mbit/s and 280kbit/s for the upload.

I've configured the traffic shaper like this:

Pipes

• Bandwidth=3800
• Bandwidth Metric=kbit/s
• Scheduler type=FlowQueue_CoDel
• (FQ-)CoDel ECN is flagged
• FQ-CoDel quantum=300
• FQ-CoDel limit=600
• Description=Download

• Bandwidth=266
• Bandwidth Metric=kbit/s
• Scheduler type=FlowQueue_CoDel
• FQ-CoDel quantum=300
• FQ-CoDel limit=600
• Description=Upload

Queues

• Pipe=Upload
• Weight=90
• (FQ-)CoDel target=15

Testing it in DSLReports show a bandwidth and bufferbload quality changed form F to B and I think this is a good improvement.

I'm asking to the community if someone can help me or have suggestions about fq_CoDel, to fine tune my traffic shape. Any help is appreciate, thanks
