I would love to see a deep dive into wifi tuning, like, the environment scan page, seeing so many other devices "DIRECT-ROKU" for example, how to avoid interference from them, etc.
Thank you for taking the time to do this video. I have a fairly "overpowered" (in a good way) setup for our house but I see a lot of signal interference from the neighbors surround us. Picking fixed channels (manual) sounds good but aren't we then susceptible to running into issues when the surroundings change, where as letting Unifi automatically change channels on a regular basis should be better ? Or are we just playing non stop "cat and mouse" because the different networks will keep adjusting in a chain reaction? Like, my neighbors router goes "oh, hey, there's noise on channel 3, so I'll go for channel 5 instead" and then MY network will go "oops, gotta run from channel 5 now, so I'll choose channel 8" etc.
It's fairly straight forward actually. If you daisy chain, your packets need to hop from their source to their destination, touching all switches in between. Not only do they take additional hops to get to their destination, but the switches in between have to use more CPU/Memory to process all of those extra requests. Not as big of a deal on a smaller network, and one with maybe 2 or 3 switches. But do this with a lot of switches and client devices.... the performance hit can compound itself pretty quickly. An aggregation switch allows you to have all switches come back to a single core switch that then is only a single hop between your normal client device switches. This let's all traffic between switches get handled and trunked to each other a switch dedicated for that purpose, without all of the broadcast chatter of the client device switches. Also the Pro aggregation switches primary SFP+ ports are 10G, so you won't have a single client saturate a gigabit uplink. If you LAG 2 or more cables between them, you'll gain throughout if you need it, but more importantly, you'll gain redundancy. If you then couple this with RSTP weights and alternate paths, you can create a fairly fault tolerant switch network. I've got a site with 2 Pro Agg switches and about a dozen 48 Pro switches setup in this way.
Performance tuning is such an important component of the delivery and overall positive customer experience. This is what separates a regular installer from the Professional. I have fixed so many of these in last the two years I stopped counting. It is an integral part of my overall service delivery. Great job and we do appreciate sharing these key pointers online with the community.
If one plans to purchase a UDM-PRO SE, to start building their network, and plan on adding several cameras (3) and several APs (2) can the Poe budget handle those on the SE version, will the cameras be affected by the 1 GB back plane? Or that is more about the connection to the ISP?
Nice video Cody. The problem with wifi is that sometimes our neighbours have wifis which automatically scan and adjust channels. So what’s low on traffic one day may not be the next.
And that's why the easiest Unfi fix is to put channels on auto and let the nightly optimisation do it's thing. Does exactly what Cody did, but every night.
If you have 3 AP's, do you put each AP on its own channel? So, for example for 2.4ghz...AP #1 would be on channel 1, AP #2 would be on channel 6, AP #3 would be on channel 11.
Thanks for this video! I just went to UniFi, perfect time! I use 80 MHz channel width in 5GHz and noticed that I get way better speeds from channel 100, even when it's more utilized. Therefore I went with channel 100. Is there an advantage for channels from 100 on?
Bonjour, vous n'avez pas présenté également le logiciel Unifi Design Center qui permet de faire une sélection des points d’accès wifi en fonction d'un plan pour pourvoir les placer correctement 😊
Dear Mac, you suggest to use channel 11 because it has 6% utilization, but that also has -43dbm interference, while channel 6 has 25% utilization, but at -59dbm. What is the rationale or formula to reconcile the two when choosing the best channel?
@@MitchellEarl That's precisely my point, channel 11 has lower utilization (6% rather than 25%) but it has higher interference (at -43dbm rather than -59 dbm). Honestly, I'd have picked channel 6 rather than 11.
Question regarding java. Upgrades now require java 11 and the software points you to an open source website. I can also get java 11 from oracle. I am currently using java 8 and my java panel saying I am up to date. Where should I download from and can I install over my current java?
Great video. Just personal experience. The U6LR has been a poor performer for some reason as far as speeds go. I have tried infinite number of channels and combinations to maximize speed. Even when sitting beside the unit, the maximum speed is 700/700. That’s essentially a third of the bandwidth loss with channels totally optimized for the environment. I’m thinking of giving another AP a go. Any recommendations? This is Home Lab setup. Not a business deployment, so my network only has a total of 27 clients.
Please someone tell me why the heck I cant send MMS messeges when Im on my wifi. I have multiple U6 AP's. One is connected to the Enterprise 8 Switch in my office and the other is connected to the ProMax 24 POE and the switches as well as my UDM-Pro SE run to an aggregation switch. Is there a trick im not seeing. Since Ive had this setup I have to turn my phones wifi off in order to send MMS
Do I need a aggregation switch for my setup? - UDMP - switch24 poe - unvr (x11 cameras) - 4x mini flex - a switch flex - and 4 AP's. All the switches and AP's plug into my switch24 and that is plugged into the udmp. The cameras are all powered by either the switch flex or the switch24.
The meshing stuff is a disaster. It keeps going into meshing mode with other access points even when their cables link is fine. Then you get a broadcast loop. I turn it off in global and ONLY enable meshing where I am using it to get an ap where we can't cat cat5/6 cable to
Surprised you didn't mention band steering, you might want to enable and set to 5G. For some reason, iPhones downright refuse to choose 5Ghz when available, they always just choose the highest strength signal which will almost always be 2.4Ghz.
0:08 Did he just say TP-Link? These network professionals need to stop saying stuff about TP-Link and people need to stop putting those security risks in their networks.
@@MactelecomNetworks I know that, but TP-Link should be avoided like the plague. All the network security people I know warn people to rid of all TP-Link and similar devices from companies in China, and many network people already avoid them, yet the top network TH-camrs keep reviewing and even recommending them. I don't understand the disconnect.
@@eyefly001 What an insightful response. You see no difference between hardware that's put together by workers in China with US firmware vs. CCP companies that make products and firmware/software that harvest your data. Nice take that shows you know nothing about security. That is not even comparable at all. Also, not that product manufacturer region matters at all other than where their money goes, products like Ubiquiti are often made in Vietnam.
@@JacksonCampbell What a delightful response. I can tell you have deep insight when you use terms as "network people". And ubiquiti is made in china, and vietnam and korea I think as well.

Could you talk a little more about using an aggregation switch V. Daisy-chaining switches? Thanks!

I always learn something new from you videos. So thankful I found your page!
I use the base aggregation switch and have all of my switches connect to that via sfp to copper adapters, works well
Your videos have helped me so much, thank you!

@@Timi7007 some experts in the ui community would highly disagree with using auto
@@raykim5568 Use-case dependent. But for installations where you use Unifi auto is probably fine.
Have you worked with the Interference Blocking function? I can’t find any information on it.
Thanks Cody, great pointers there
Great video. Thanks for sharing. Cheers
I like how you turned it up to eleven 🤘
Updated to 2.5.x ea on my udmp yesterday morning. Works like a charm. Expect it to be RC soon
Ya once it’s general I’ll do a video
How do you update to 2.5 I'm stuck on 1.9 and says no updates available
For access point specifications like what radio supports which standard, MIMO etc. Evan McCann's blog is a great resource.
Yup I agree. I’ve referenced his blog before a few times
If you have 3 AP's, do you put each AP on its own channel? So, for example for 2.4ghz...AP #1 would be on channel 1, AP #2 would be on channel 6, AP #3 would be on channel 11.
That’s correct
Is there any speed difference between the 5ghz channel choices? Assuming there's no interference or issues with dfs conflicts?

There shouldn't be anything special about that.

Does the UDM Pro SE also has a 1 gbit backbone shared between its 8 network ports?

-43dbm is a stronger signal than -59dbm. The lower the dbm, the stronger the signal. Just like golf ;)

@@RobertoFabrizi Sorry, I missed the "interference" part.
I would expect the automatic nightly optimisation to select the least used channels. Why does this not happen??

Great vid.
First? Also, Cody rocks!
Def, he’s a huge reason I decided to go unifi
Bro... what happen if you daisy chain the xg24?
Is it really more advantageous to manually select channels for the 2.5 and 5 Ghz signals as opposed to leaving them on Auto?
Depends on the environment but typically when we do businesses we manually select

What application do you use to create your network diagrams?
LucidChart
What tool do you use for network diagrams?
Lucid.app
How do I change devices from U6 Lite to the BeaconHD without switching them to a different Wifi name?

I never realized that the AP6 LR only had wifi6 on the 5ghz, have two installed at home.. What does this mean?
Just means any device connect to 2.4 won’t have wifi 6 :) most newer devices if close enough to the APs will be on 5Ghz anyways
Thanx ;-)
Do you consult? I’m looking for someone that can help me dial in my network
I do
Visit my website
www.mactelecomnetworks.com
why only channel 1 6 11 there are more channels with good stats whats that about
Channels 1,6,11 are the only channels that are non overlapping for the 2.4Ghz
Why do all these videos push towards Transmit Power Auto for 2G/5G?
You can set it to whatever you like but to truly test what the power is doing you need a good wifi tool
I have reached out to you and you You started Communicating And then Stopped I'm waiting on you to complete my system And help me in my conversion
What program did you use to draw walls and wifi signal at th-cam.com/video/NCnRhYGMzvA/w-d-xo.html
Unifi Wifiman
Can't get the wifiman signal thing to work
You probably need a udm for it.
