Fixing one OS at a time, one router at a time, one home at a time, and one ISP at a time is growing to be a bit tedious for me, but I am always glad to excite others! > I installed cerowrt 3.10.50-1 on my Netgear WNDR3800. I note that after another year of development openwrt chaos calmer is nearing a freeze and has all the chocolatey goodness that went into cero. After you get a little familiar with cero you might want to fiddle with the newest stuff from them. > My question is, will this work with verion fios? It depends on your speed. Weak hardware such as the wndr3800 starts peaking at about 55Mbits of shaping. (chaos calmer is faster, have not measured) So if you have the Verizon 50/50 service you cannot shape both directions, and higher, you are out of luck - however, see below. And you have to configure and enable the SQM subsystem to slightly less than your configured rate. See the gui for that. > Reason is Verizon has a combo router/modem. They CAN be configured in a bridge mode if you desire, but you can usually just put cero in front of it to do everything else (shaping/wifi) and be golden. See the intertubes for how to switch to bridging verizon gear (if you want to). It is overly complex. > I=E2=80=99m not sure having if I connect PS4 > Netgear > Verizon Fios wil= l benefit buffer bloat. One of our longest running deployed cerowrt + fq_codel setups is over at ESR=C2=B4s house. He has 25/25Mbit fios. On that particular modem and particular setup we found that doing download shaping was all that was needed. This was the latency under load behavior of FIOS on his line on the rrul test (which tests up and download simultaneously while doing a measurement via various forms of ping): http://snapon.lab.bufferbloat.net/~d/esr/rrul_be_thyrsus.svg which peaked at about 120ms of added latency under load - certainly enough to be bothersome for your gaming experience when someone else uses the link. After we added 24Mbits (?) of downlink shaping and did not do anything that I can remember on the uplink, we reduced that to about 3ms of induced latency under this full load. http://snapon.lab.bufferbloat.net/~d/esr/rrul_be_thyrsus-fq_codel.svg There is a complete dataset in that url evaluating various aqm and fq algorithms against the fios 25/25 service if anyone cares to look. Eric is also probably now the world recordholder for cerowrt uptime - Jim Gettys ended up rebooting his box at 273 days or so, only to find it was actually his cablemodem wigging out. There is something magical about cutting software releases from eric=C2=B4s basement, for open source quality, I think, and this thread was pretty funny. http://esr.ibiblio.org/?p=3D4566 > Maybe my setup is incorrect. You are not supplying enough info. A lot of people have tended to think this stuff is merely magic. No... you need to do a measurement, preferably with something better than speedtest like the rrul test suite, change two settings for uplink/downlink, and tune - and *then* you can forget about it. This is an example of a tuning session against a cable modem. http://snapon.lab.bufferbloat.net/~cero2/jimreisert/results.html > > I have been struggling with latency while playing on my PS4 kids streamin= g on youtube, and wife surrfing and hoping this will help. It certainly will. > I do understand there might be issue with certain games net coding but ho= peing to eliminate as much as posible. Not really. You can add in some classification if you must but the above stuff will usually take care of it. > Any suggestions would be appreciated. Run a good up/download test (try it with speedtest if you must, but run a separate ping while you do), Turn on sqm download shaping with parameters 95% or so what you get from speedtest- re-run the test (you will lose some bandwidth but get all your latency back, hopefully. If not, well, some fios cpe is different from others, turn on upload shaping, measure, repeat) There are numerous tutorials as to how to do this step on the web now, and yet it is my sincerest hope that the big isps will merely deploy this stuff on their gear and enable it by default. It leads to a much less annoying internet experience.
