I am using fq_codel on a Ubiquiti EdgeMax router. Whereas it seems like many people running this router are focusing on really fast connections, I have slow DSL connection with a 400 kbps uplink.

I'm trying to figure out if there are some recommended fq_codel settings for slow links like mine, or a way of optimizing my settings?

The best I've been able to find so far is:

which makes it seem like I should set the "target" to at least 13 ms (or more?), set "limit" to 600 (or less?), disable ECN on the uplink.

These settings I found are still for links several times faster than mine, so I'm wondering how I should change them, or if there is a good way to try varying something and measure this to determine the proper numbers. Thanks for the help,

Nick
