I think that while PIE is "mandatory to implement" in DOCSIS 3.1, the ISP still has to turn it on? So maybe yelling at them will work?

My Turris Omnia is doing fine on my 1Gbps connection (although that hardly suffers from bloat, so I'm not doing any shaping; did try it though, and it has no problem with running CAKE at 1Gbps). -Toke _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
