Comcast XFINITY → Re: [Connectivity] Upgraded to 400Mbps and now YouTube stutters constantly..

but why? when comcast will have everyone on on their network at docsis3.1 in the next year. so then now your already outdated, aqm and the benefits of docsis 3.1 are worth it.

does comcast even have aqm enabled yet? i doubt it, i dont see anything different

No MSO has formally announced enabling AQM (at least none that I know of). On the other hand, placebos show success in many patients who want to believe.

did many tests before 3.1 was enabled in my area. after i no longer need to use qos. docsis 3.1 aqm is built into the spec. they also recommend docsis 3.0 use it but not required on 3.0.

"This technology shows such promise for radically improving the broadband user experience, that we've mandated it be included in DOCSIS 3.1 equipment (both cable modem and CMTS). We've also amended the DOCSIS 3.0 specification to strongly recommend that vendors add it to existing equipment (via firmware upgrade) if possible."
