Posted: Thu Nov 30, 2017 13:40 Post subject: WRT1900ACS v2 QoS and bufferbloat
I had QoS working and bufferbloat under control (~20ms up and down) with r30949, but decided to update. Download bufferbloat stayed in the same range, but upload jumped up to ~400ms, the same value I get if I disable QoS. After trying 7 or 8 versions, I was able to find the last working version to be r31899.
Relevant Settings (I think):
Packet Scheduler - HTB
Queueing Discipline - FQ_CODEL
Downlink (kbps) - 27500
Uplink (kbps) - 27500
All TCP-Packet Priority boxes checked
Everything below left untouched
My Frontier FIOS connection is 30/30, but I tried lowering the values with no change. I also disabled SFE on later versions that had a checkbox available. I'd love some help if there are some settings I can try, or I can help if there's any testing I can do.
Similar ticket but either way, the devs refuse to work on QoS at the moment. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

Thanks, I wondered if it was known but didn't know how to find out. I wish I could go in and compare the versions I mentioned and just copy and paste the old QoS code back in. Not that simple, I know, but it'd be nice.
