WI-FI 6, Why it's the BIGGEST update to Wi-Fi EVER! - 802.11ax 

29 years old and I've never seen anyone get the point across so easily, and at the same time make it so interesting. Loving the vids so far man keep it up!

Am a computer science student I graduated from university and one thing I can confirm is that what I've learnt all this years from Google and RU-vid is more valuable than what my lecturers taught me back at school 🙌🙌

Loved the delivery, but missed some other big things 1) Wifi 6 brings beam-forming to 2.4ghz 2) Wifi 6 devices are allowed to "talk over" another device as long as the other device has weak signal strength. This reduces competition for spectrum in high density areas. 3) Wifi 6's new signalling reduces the latency quite a bit. Something like 1ms instead of 10ms. It doesn't sound like much, but when you have packet-loss and the wifi frame has to be resent, it can be the difference between 5ms and 50ms. 4) Wifi 6 can do full duplex if the devices support. The protocol supports it because of OFDMA

Where the hell did you all find this guy? He's great a teacher at heart, I subbed

NetworkChuck: Just as long as they don’t make the next standard Wi-Fi 6S Wi-Fi Alliance: Hold my antenna... Introducing Wi-Fi 6E

Nice video. QUICK TIP; if you want to get rid of the color cast you're getting when keying out the green from the drawings. Try drawing on a black background and using the "screen" blend mode option instead of chroma keying.

I just started preparing for CCNA and your channel is really keeping me motivated to get into the network-world. 👌 Thanks for all the effort you are putting in this.

5:40 the Bob Ross of networking. Haha that's awesome

the hub -> switch reference took me back to the days I upgraded my hubs....right in the feels man.

Tried to learn from many sources about Wi-Fi 6. But none were close to what I learnt from this video. Thumbs up to your delivery and the way you presented all the features.

Hanging out with CBT Nuggets members improved your explanational tutorials I can notice. Well spent time Chuck. :)

“Maybe one day, none of us will be in the office.” - Pretty apt observation, Mr. Network Chuck! It came sooner than any of us realized!

I'm surprised that I didn't hear anything about mu-mimo

The green screen in photoshop move was genius, I am glad you showed the view to let me see that :)

Public WiFi isn't bad because of current WiFi capabilities. ac is great. It's because providers of public WiFi deliberately throttle throughput bandwidth and speeds because they're cheap.

Every hard definitions just turn out so easy to understand. This is insane!

He is such a good teacher. I just amazed how his presentation drew my attention till the end of the video

Hi Chuck, I just want to say that I appreciate you and your videos. You really make all of the IT stuff approachable and make it all of it seem doable/learnable.

Lol.. “one day we’ll all be teleworking from home” Welp... it happened

Jeez, man! Gotta say, you're the best teacher I've ever encounter. Absolutely best tech video I've ever seen. Thanks a lot, dude.

This may be the best tech video I’ve watched ever

The way this guy explain is just amazing. Totally love his videos. Keep going chuck.

I love how enthusiastic you are about this. I know Jeremy from CBT Nuggets is the same way. If everyone were as helpful as you two... the IT world would be a happier place.

Wow. I'm not even done watching this video yet and I had to pause it so I can comment on how great you are at explaining this! Dude...I shouldn't even disrespect you by saying dude but I would pay to sit through a classroom as you teach us this new technology. Very well explained and easy to understand. Keep the videos coming! Thank you.

Makes you angry does it? Wait till you find out that each core on your computer only runs one program at a time and it just switches between them giving each a little compute at a time.

I got it now, devices I have support it. In the appartement building is a lot of noise. But now I have full ISP speed, absolutely maxed out, latency very good, no lags on any device. Perfect upgrade!

Man your training is awesome. Your method should be trademarked. Thank you.

I am a Residential Technician for Xfinity, since we implemented WiFi 6 (802.11ax) modems, I have found that they are way better in terms of latency and troubleshooting. At first, the modems did have a couple of issues but they have since been resolved

made me understand IT more.. I love the way how you get the point across in a more understandable manner. Made it easier and more interesting. Thank you!!! keep it up!

literally pumping this video through wifi 6 right now

The background music should be a little lower in vol. , it is distracting,,, ✨

CHUCK, I've been contracting for a hospital for a year now installing ethernet cabling. Every other patient room is red and blue networked and every 3rd room gets an opposite colored WAP. I've always wondered why they insist on this but now, thanks to your video, I understand that they are simply preparing for WiFi 6 and the new technology concepts. I freakin love computer networking. Thanks for all your videos. Fan for life lol.

I have WiFi 6 with my unifi network at home. I have 4 of these new access points. Key thing to note is the network uplink is 2.5gb or 10gb because of the new abilities of 802.11ax .

I'm still in April fools PTSD checking when any video in my recommended was published 🤣

Peter McKinnon's hipster geek brilliant brother. Love your videos. Seriously. The content is AMAZING, but you may want to think of bumping up your audio levels just a couple notches because when a commercial hits, the audio is so much louder. I'm not sure if it's them or you. Just something I noticed. Keep making great videos!

I like how he randomly started playing VR while explaining

Thanks Chuck for taking your time to teach us things. I been watching your videos for a time know and you really do put it in a perspective we can understand.

Just ordered my UDM Pro SE and the U6 LR. Pretty excited!

Great video, super informative 👍🏼, would be much better if the topic took only 10 or 5 minutes max. Keep up the great work.

Amazing explanation! If I only had teachers like you when I was getting outta high school I would have gone to college for the computer industry

Hey! The wallpaper on your computer in the background there is from Gásadalur (Faroe Islands). Been there many times because of my family out there (I'm half faroese) I'm currently working on my CCNA and I love your video's! Keep up the good work! :)

"I'm at the mall right now" 😭😭😭😭😭 R.I.P. 2020

This is an underrated breakthrough.

surprised !!! I'm an IT Engineer and didn't no this , amazing ! WIFI 6 , thanks Man

Hey Chuck, how does this compare to MIMO. Does this new standard reduce the need for MIMO?

This is an old video but I wished I watched it when it was uploaded. Excellent job breaking this stuff down comprehensively even for novice like me.

Nice information but was a bit of a drag with too much time for every small term...

My 4 y.o. cheap TP Link router 802.11 can't even talk to an Alexa device on the 2.4 band 6' away. I'm done with the old router. I've added several IOTs like most people, Ring Doorbell and Security System, cell phone, laptop, TV, some smart plugs. It's time to upgrade to Wifi 6. Thank you for this fantastic video.

what about security if modem gonna send a one big packet with information for lets say 5 devices so if you can intercept that one packet you will be able to get alot of more information, isnt that gonna be a issue ?

Love your channel...watched a few videos earlier today and now I'm hopping around. Subscribed!

They should name it like USB 3.0 This could be " Wifi3 Gen 2.2 acXnXbg 4x4 "

Congratulations on an absolutely fab video. The best I've watched on WiFi6. You're a natural teacher. Will 802.11ax improve the ability of WiFi to communicate frequencies through normal internal house walls etc; or is that still largely solved by mesh routers?

This is a huge change in the wireless technology, it's been a while since we first time heard about it. But the standarization and industrialisation process just takes too much time, up untill now we still don't see it on the market yet.

new to network world since then enjoying each second of my life

MU-MIMO came out with 802.11 AC (Wave 2), so it's been around for about 4-5 years now. However, OFDMA is new.

A Billionaire Somewhere : I prefer all the lanes to myself Jeff Bezos : Fuck it, I'm going to space

Omg watching this and laughing. I'm studying for A+ exam and this was super helpful explanation on differences between 802.11 ac/n and now ax. But the reason I'm laughing is bc you said maybe some day we will all be working remotely. You said that 3 years ago. Then Hello Covid! Great video! Thanks for sharing all your wisdom.

Thanks. Good info. If I may submit a user feedback: too long of a video for something that can be explained in 3-5 min

Fantastic explainaton on the new Wifi 6 standard as well as how wireless networks work in general. Very good!

This video reminds me of that Steve Jobs video presentation unveiling and asked everyone to turn their phones off because they were all connected to the wifi crashing his demonstration

Gezz, 5 sounds like a supper fast Token ring....we just need a few more devices at 6. Oh ya, It's sad that most people don't change the namen of the 2nd wifi. 6.....so they can see the difference. Give it a 👍 you know this. I love this 😀

You put off some pretty dope Bill Nye vibes man. Awesome Video!

Absolutely love your attitude and excitement, it’s contagious! You’ve made topics that I’ve found daunting to be much more exciting, leading me to purchase a subscription to codecademy to get started with Python. Keep up the great work and keep on loving the Lord!

18:28 - 18:32 As soon as you said, "Wait hold on. Do you guys hear that? There's like some guy talking." An ad for #WiFi came on. My app stalled, I refreshed and then an ad for blood flow came on. I thought that was intentional.😜

Therefore the Intel 5300 WLAN interface on my laptop is a Wi-Fi 4.0 (it is supporting 802.11n by default but it is backward compatible with older WLAN equipment - 802.11b/g).

This dude makes me want to be in this field soooo bad. You are providing a great service my man ✊🏿 great vids btw 👌🏿

The only sad thing with .11ax is they didn't deprecate (nor retire) .11b modulations (non-OFDM specifically). Looks like we have to deal with those airtime hogs for a few more years.

Loved it. If I did understood it correctly, Even if we add more devices which need more bandwidth for the best experience, there will be little to less effect on other devices which have been using less bandwidth already. That being said, devices using high bandwidths might suffer if there are new devices connecting to the AP, and maybe at a point when AP reaches its threshold of devices (or it cannot further divide the entire channel ) then only all devices will feel the heat.

Chuck: “It’s easy, just so long as they don’t do the next standard as WiFi 6S or WiFi 10” WiFi 6E: “Hi there..”

just to be correct (as this was seen in the video at 1:15), the correct name is 802.11ax, not 802.11AX.. case sensitivity is a thing with the IEEE :) edit: I understand this might have been due to the used font..

Its like satellite communication. The access point is acting like a network controller in MFTDMA (Multi-frequency time-division multiple access).

Woohooo 2.4 - that is the sleeper. Can get across buildings and through objects. OFDMA is the star but so good to hear about 2.4.

You're a good speaker but come across as that overly chipper Cisco salesman that insists on taking you out to lunch a little too often.

Chuck your simply Awesome. I am so slow and dumb in understanding this things but now i'm learning a lot from your videos.

really long winded but that's because I'm not the target audience.

and here i am watching the video on mid September 2020 considering upgrading my wifi tech

Is there an answer to outdated hipster looks? That needs to be looked at after wifi is solved.

What a fantastic presentation! Chuck you are a great teacher. Easy to listen to, easy to understand.

Attacks on AP's just got so much harder. Now you would need to attack the AP on specific services its already running, hoping they're vulnerable. If you wanted to spoof a device it sounds like you'd have to match its bandwidth signature because its smart enough to know not to receive communication at certain times instead of always grabbing for it.

Thanks, never have I had wifi explained in more interesting and compelling way. Great work.

The key to excelling in the 2.4ghz band is to realize, you got more channels than just 1,6, and 11. You actually can use two sets of channels in different staggered local areas... 1, 5, 9 and 3, 7, 11... with 14 as a bridge channel This gives you 7 channels to work with, not 3. In one building you use 1,5, 9... and in the neighboring building... 3, 7, 11....... and the building next to that one... 1,5,9 And channel 14 (set your router reglatory area to Singapore setting to get a Channel 14) to bridge buildings 1 and 3 together. I like to do my bridges however over the 5ghz band using a 80mgz wide channel. See, the thing is, most handheld devices and indeed most devices, only support 2.5ghz. Very little user equipment supports 5ghz still, and nothing supports 6ghz. Which means 5ghz and 6ghz can mostly be used for bridging. It also explains why 2.4ghz is so terribly overcrowded in metropolitan areas, because most people have no clue how to use it and just jam up everything everywhere and step on everybody. I've been in some areas where there were 20 access points all in the 2.4ghz band on a street... when really, only 3 were needed. There is no collaboration between neighbors, it's just a nightmare free for all making it work for.. nobody. I live in the countryside, and I use the entire 2.4ghz and 5ghz band optimally, and everyone has bandwidth faster than 4g that connect to my network. It all comes down to the difference between a freeforall public nightmare abusing the commons, and a slick savy network administrator with dictatorial powers setting up everything correctly so no channel stomps on another.... and when it does, it barely grazes the edges do to proper cell planning.

WOW this was great! Thank you for posting this - I am SOOOO sick of hearing people doing AC vs AX comparisons and giving the wrong information! I had a good laugh though, because I use the same highway analogies when explaining this to people :)

This is the best explanation I have seen on WIFI 6 so far. Instant sub. Great content

Your "WiFi 6s" joke aged like fine wine, considering they dropped WiFi 6E a few months after this video :D

Hey bro... I really liked the video, I have to be honest... you did so well that I will start using the idea you use to explain how wifi works to my customers. I work at Cisco TAC for the wireless team and some times stuff gets too complicated to explain it to someone that has no idea how wifi works. The simplest the better... great content!!

My biggest question is really regarding how long it will take manufacturers to begin integrating WIFI6 into their IOT devices, in particular little devices like smart plugs and switches. I have been transforming my house into a smart home for several years, at a large investment. I soon realized that the limitations of current Wi-Fi routers and APs is around 32 devices. That may sound like a lot, but it’s really not. I’m not even done, and I’m already up to 52 devices at any given time. Hardwiring a 2nd AP and bandwidth-heavy devices like AppleTV 4Ks, along with creating 2 separate SSIDs to split the load, has alleviated most issues. Another huge benefit was moving as many IOT devices over to dedicated hub-controlled products, like Lutron Caseta and Philips Hue, which use their own proprietary network to communicate with all their devices. But they are expensive, and the vast majority of new smart devices coming to market are not utilizing a hub, and they actually advertise it “No Hub needed!”, like its actually a benefit, which always makes me chuckle a bit. If all my 52 devices in my home were running independently on my network, I would have nothing but problems....and I speak from experience. But most people will make the same mistake as I did, slowly investing a bunch of money in these devices over time, till they reach an amount of devices that starts impacting performance significantly. So I return to my original question, when will we start seeing these devices? I have seen WIFI6 routers begin hitting the marketplace, but that will not make any sort of impact on a home that already has a ton of devices that cannot utilize that OFDMA feature. You may want to clarify the statement that WIFI6 is backwards compatible, which is correct only in regards to older devices still being able to simply connect to the network, just as 802.11n was backwards compatible with g/b/a. If I’m mistaken about this, I would really like to know, and I would never be so happy to be wrong haha. But as it stands, other that my hub-connected products, I will have to invest a bunch of money to replace all my current IOT devices, in order to be able to utilize OFDMA, and continue expanding with the ever-growing amount of smart devices hitting the market. Thanks again, and great job on the video!

Honestly kind of crazy that you foresaw the development of IoT devices and the necessity of a better wireless network. Can you do a video on Matter?

Can't wait with your music driving to work

It an amazing content especially when the access point said:- "Hey, everyone, be quiet!" it is a fantastic expression that tells you how the control might come to Wireless devices like A.P. and the controllers especially if we know routers and switches controls everything in networking infrastructure L2 and L3 protocols. Again I love your content a lot. Thank you!

More ram,processor speeds, and wider channel 40/40 5gz less noise but the wider the spectrum the more with the obstruction will limit connection speeds, low barring walls etc...

You almost forgot TSN which is now also a part of wifi 6.

Hi, new to the channel. I've just started my education in IT, however I admire your enthusiast for this subject. Thank you. Liked & Subscribed.

Chuck, you’re saying that 802.11ac got fast over they years comparing it to a highway adding more lanes. I see a little problem with that comparison. I would say more accurately that 802.11ac is currently like a one lane highway and just increasing “speed limit”, but it’s still one lane, while 802.11ax (WiFi 6), is actually adding more lanes to the highway, that way more cars can drive fast speed limit next to each other. Wouldn’t you say so?

Keep up the tutorial and teaching, you have such a great way of teaching! and use of pictures really makes all the sense to conceptualize whats going on behind the ones and zero's. Thanks bro.

This is a beautifully made video, clear and precise. You sir are a legend.

I'm still wanting 802.11AF because if sender/reciever are designed and configured correctly it could work very well for rural ares where you might have endpoints obstructed by trees and housing

This is really interesting thanks. I didn't realise how big this change was. I currently have 4x Ubiquiti UAP-AC-Pros covering my house, but it might be time to change. One question, my previous logic has been that really wide channels aren't always helpful as the EIRP is limited by regulation, if I have 53dBm of power I get more range spreading that over a 20mhz channel than say, an 80mhz channel. Does this mean that if a client has a poor antenna, but is allocated a 1mhz spectrum chunk by OFDMA, it should be able to have it's signal reach the AP pretty easily still as the power limit is being used in a tight 1mhz chunk of bandwidth?

Would look better to make the drawing opaque and just put it right over your right half of screen, which currently shows a green looking screen we don't need to see. Your eyes would be facing the drawing as well.

The analogy i use is: Imagine AC or B/G/N wifi as where, the router/CPE is the point where all trucks meet. The trucks are all carrying their own data package from every conencted device back to the router/CPE. This creates a trafficjam because, well all the trucks can't enter at the same time. Only one truck can enter at the time. AX wifi is basically where we say: Screw all those trucks. Let's just have one big truck which can carry all the packages from all the devices all in one drive back and forth. That way we don't get the trafficjam and the packages are transmittet simultaneously

3:50 That's not how it works in wifi5 with MU-MIMO. You can communicate up to 4 devices simultaneously. If someone Pays you to promote something don't lie about the thing that it suppose to replace.
