Very useful video Willie. Thx

[@PE4Doers]

Very useful video Willie. Thank you 😊 (and you got my 'Like')

[@beardenbob6567]

Still not clear about whether there is any detriment or beneficial effect turning on QoS when the connection is >r 300Mbps - you seem to have a 1G connection - yet you turned it on. Should we, or shouldn't we? As always, appreciate the great content.

[@simoneatough6391]

From my testing, this just sets a maximum rate per client. Even the built in speed test in the unifi UI. I had it set to 40mbps for a 50mbps internet connection. When i upgraded to a 100mbps connection, the speed test results still sat around the 40mbps mark, and any speed tests from clients had the same results. Disabling smart queses allowed the clients the full connection speed, as well as the speed tests within the UDM SE UI

[@jsmithepa]

That's not smart at all.

[@Richard_GIS]

Have you seen under Switch Ports, there you can define a phone network, maybe this is then considered to prioritize for the QoS

[@WillieHowe]

Try it and let me know the results. However -- you'll find that's only for LLDP-MED.

[@harrywillson8678]

Sorry if you don't mind me asking but, are you supposed to use full bandwidth for qos or set both values to 90%, im confused, because of other guides ive read.

[@WillieHowe]

I usually test it before settling.

[@robkwatson1]

Is the Bandwidth Profiles also used to manage bandwidth to be sure lower priority items don't overwhelm the system?

[@WillieHowe]

It's not QoS though.

[@user-ss7kr6nf5e]

Hello, I changed my provider to fiber optics and reconfigured my network, the unifi APs are fine but the speed is very low, downloads stop, etc, my internet is 10 mbps, could you help me, I don't have a unifi controller, thanks

[@Dreathan]

Either old cables or old switch/router on the path. 10mbs suggests eirhet one of cables on path to internet is old/broken limiting to 10mb/s or switches/routers on the paths are very old and dont support any more speed (or both:D).

[@vitorao]

Any idea why Ubiquiti does not recommend using smart queues for connections faster than 300 Mbps?

[@WillieHowe]

Assuming it's hardware offload related.

[@vitorao]

@@WillieHowe, is it possible that they are considering that most users that use Unifi routers will not need QOS if they have a connection faster than 300 Mbps? In other words, does Ubiquiti think they would not need a queue policy because their speed would not even be a bottleneck? I know that is not every user's case, however. If I don't use a smart queue in my home, for instance, which has a 600/300 bandwidth, it is easy for a download of a huge file from a fast speed remote server to impact the quality of a videoconference call or online gaming, for instance.

[@WillieHowe]

@@vitorao If you're serious about voice you should always use QoS.

[@vitorao]

@@WillieHowe, yes, I agree. That's why I think it is strange that Ubiquiti does not recommend using it with speeds faster than 300 Mbps.

[@haroldpepete]

edgeroute does have a decent qos management, he has smart and traditional queue

[@vitorao]

Yes, Edgerouter is an excellent choice for QOS Management. The main disadvantage with EdgeRouter is that it does not run Unifi Applications. If you are deploying Ubiquiti's access points for instance, you would need a separate device to do that. That is the reason why many users (including myself) stick with Ubiquiti Dream Machines.

[@MitchellEarl]

I was under the impression that UDP packets also got priority with Smart Queues. Is that not correct?

[@WillieHowe]

Smart queues should be all traffic.

[@byrd203]

they need QOS based off the application as well take a look Peplink QOS is really good you could use a poplink firewall to get good QOS and unifi switches because peplinks is app based by traffic type all devices get what they need when they need it its rated for any speed along as your firewall supports 1gb or more I have the peplink balance 305 unfi had to many turn offs still kinda does unfi needs to step up their game big time uhm USG anyone blah multi static ips blah plus windows based unfi controller unfi needs to fix all of these I do admit there switches are ok its the firewalls blah I say mix peplink firewalls then unfi switches problem solved

[@BobFrTube]

QoS is a legacy of the 1970s smart network -- second-guessing devices turns out to be a bad idea. That's why we have protocols like TCP for sharing from the edge.

[@WillieHowe]

What?

[@jsmithepa]

What?^2

[@richardturkson5916]

Smart Queues for UniFi products are utterly useless (simply the square root of zero, no value added). It is a weakness and gap they need to bridge soon if they claim to sell a one-stop shop device. It is my hope Ubiquiti has future plans to address this underwhelming feature.
