what causes nbn dropouts

Here, your modem is the bottleneck and can introduce bufferbloat.I'd suggest that anybody interested in fq_codel instead looks into cake, which is basically a successor to fq_codel specifically focused on this case of shaping 'last mile' internet links. posted 2018-Feb-8, 3:56 am AEST FTTN connection, home phone is effected too!Try changing to a different ISP and see if it makes any difference.How to Share Non-iTunes Purchased Music across Apple DevicesOptus says it's NBN, NBN says it's Optus.Seems there is a issue on copper line from node to your home. posted 2018-Jan-12, 12:25 am AEST Isn't that for v3 hardware?do you realise how deliberate you would have to be to use the whole 40mbps (~4MB/s) upstream bandwidth? https://queue.acm.org/detail.cfm?id=2209336Asus DSL-AC88U NBN DSL log screenshot (dsl uptime 90mins): I don't have an NBN connection yet, and even if I did I am sitting in a hotel in North America right now so could not test this, but I expect the OP can. posted 2018-Jan-11, 8:59 am AEST I believe the USG can only handle about 60-70 Mbps aggregate when doing SmartQueue. posted 2018-Feb-1, 8:00 am AEST shape correctly into the network and the it should never be shaped harshly again or hit a policerIt is possible by configuring a shaper in the upstream direction of the link, if your router supports that. The most common dropouts will often result in a loss or change of status lights on the NBN Co NTD or the WAN light on the Netcomm modem. The causes of issues we find with VDSL are essentially the same as with ADSL but the effect on the service is multiplied by a factor of 10 There are many causes of slow speed and loss of connectivity on an NBN VDSL or ADSL service. Note: Severe weather conditions resulting in heavy cloud cover may also cause connection dropouts.

Can we do similar with the Unifi USG?

No real issues.Optus: We will send out our technician to check out the problem.It does make sense to eliminate all possible issues. This case is the exception where ISPs have control in the downstream direction of the link and would (should) generally configure a shaper on their gateway to avoid running afoul of NBN Co's policing mechanism. posted 2018-Jan-11, 8:50 am AEST posted 2018-Jan-11, 11:55 am AEST posted 2018-Feb-25, 11:47 pm AEST

fq_codel can't operate on its own, it needs to attach to a shaper to be useful in this case.

posted 2018-Jan-12, 2:46 pm AEST me: the NBN technician. This doesn't cause a drop-out, however it can result in slowness in establishing connections when the link is under load as excess packets will be dropped more or less randomly. posted 2018-Feb-7, 9:28 pm AEST For how long have each of your mates had this outstanding FTTN performance?What fq_codel does, is add 'smart queueing' to this shaper (normally htb) that aims to isolate each queue and its associated latency from each other, and to fairly share bandwidth between them.

Can you guys fix … The most common culprit is … 39Mbps, then NBN policer will never see a need to drop your packets.I spoke to the Internode helpdesk yesterday wanting to know the cause reason for a dropped connection with my NBN FTTN 100/40 line (100m to node in postcode 5000, sync at 110/45, max sync at 130/50, no peak-time slowness) but I digress.

Especially with the increasing home use of services that upload a lot of data (online backups, dropbox, video conferencing, etc).just streaming/uploading to Youtube or Twitch TV.Bufferbloat is only ever an issue on the bottleneck link, which is almost never going to be the WAN interface of your home router. posted 2018-Jan-11, 12:24 pm AEST That whole OP write up is not unusual.Once that's done, keep the receipt and any report as proof that your internal wiring is perfect. I don't think it's possible to self-throttle, but if it's true, it really seems like something that should be fixed, or at least have a workaround? Other than that, the VoIP light from the Huawei modem turns OFF when it happens. A user experiencing on average 2.4 resync events (colloquially known as dropouts) per day as being connected to a “stable” connection. The link between you and your 10GbE switch will see 0.4% utilisation, the link between your 10GbE switch and 10GbE router will see 0.4% utilisation, the 1GbE link between your router and the NBN Co NTD will see 4% utilisation, and the policer within NBN Co's network will see 100% utilisation and drop packets in excess of this in order to signal to TCP to slow itself down.

Is it true? The problem of bottlenecks (which are driven by rate changes) can lead to a standing queue at the bottleneck aka bufferbloat even with the network in its steady state as described in the article.
