I'm the kind of guy to be spending his new years eve watching detailed WIFI tutorials. Thanks!

Again I have to give Quinn and his team props for doing their research and presenting it in an easy to consume way for non-networking folks. As a network engineer, it's refreshing to see a tech KZfaqr focused on a multitude of tech going into just a little more detail when it comes to networking. Also thank you greatly for preceding on how to properly run speed test and cover how bandwidth is shared from the uplink from the provider to the wireless. Back when I started in the NOC, 90%+ of the support calls were related to it. As always, great video and if you decide to do more in-depth network videos, I'd be glad to provide some insight from the ISP perspective

21:50, Channel 5 will be overlapped by BOTH channel 6 and channel 1. On 2.4Ghz, the only non-overlapping channels are 1,6 and 11. you had 7 networks using channel 1, and they could potentially ALL interfere with channel 5.

It is always amazing to see you covering the basics in all your videos. I am power user and Network Security Architect, it is so inspiring for me to see the way you put any complex topic together and make it much easier to understand. Man trust me, it is tough to explain things easily when you know the actual level of complexity/science behind the circus.

This was such an incredibly well done video. Quinn you continue to excel at communicating complex topics in a simple, easy to understand way.

I actually install high speed data for a local cable company and this video covers alot of what we are taught and what we're supposed to educate customers on if they have any issues. I will definitely see if any of my customers want to learn more I can send them this video!

I love your videos so keep making them. My local ISP got a government grant of $619,500 to go along with their $1,150,500 investment to upgrade 1,650 houses in my area with gigabit FTTP and It's absolutely incredible having 1000 mbps down and 1000 mbps up after having DSL with speeds like 9.95 mbps down and .80 mbps up which I don't miss at all lol.

Great video to send anybody who isnt that techie, but wants to know more. Thank you Snazzy you are the only guy that explains things this thoroughly, yet simply.

Very detailed info and I loved the graphics, great work!

Thanks for always going deeper than everyone else on tech topics, it's super informative. Would love to hear your thoughts on *wired* mesh points vs. a router + wired access points like Ubiquiti's stuff.

nice. one thing about wifi 2.4ghz, everyone should be using channels 1,6,11 and the rare available 14, because the rest of the channels are overlapping, so choosing one of the 2,3,4,5,7,8 etc will introduce more interference than before (because channels 2,3,4,5 are overlapping with ch. 1,6 and with eachother).

Great video to start the year! Thanks Quinn hopefully this fixes some issues with my internet! Totally focused while watching this! Happy new year Snazzy guys!

Top notch tutorial, well done. Love Snazzy Labs. One thought worth mentioning is the monthly rental fee many ISPs charge for the modem/router/access point which can be avoided by using your own equipment.

You definitely do not want to be using channels other than 1, 6, or 11, even if one of those appears to be non-congested by itself. Co-channel interference is a much better choice than dealing with adjacent-channel interference. Selecting 40mhz bands make this even worse on 2.4ghz. I would post a correction on this because the omission of this information could lead to a lot of people picking say channel 3 for instance because it appears non-congested and wondering why their wifi connection is terrible.

Man I really love your channel, even though most of the information in this video already known for me...but realy enjoyed how you summarized the information and simplified it.

Another cool idea that I use for my Eero wired backhaul: Moca Adapters. I don't have cable TV, so my coaxial jacks are being used for gigabit ethernet throughout my house 😎 Highly recommended!

Such an underrated channel! Thank you Quinn for the quality content!

Love all the deep dives and explanations you do in every video

God, I love your videos man. I’m the techiest person of all my friends and family but I’ve been going nuts buying different mesh networks and 802.11ac routers the past 7 years because my house is a long shotgun in some ways with a professional recording/streaming studio in the back. I learned SO much from this video and am really excited about seeing how the transmission power trick helps things out. Thanks again :)

Remember to upgrade your own equipment if you've been on the same ISP for a while. I upgraded from 100 down to 500 but my old modem I got over 10 years was docsis 3 and capped around 300 but realistically was around 150. Upgraded to 500 down and so I also got a docsis 3.1 modem and getting close 490 on a good day and average between 350-400 down over wifi.

I always enjoy your videos! Well researched and edited. Keep being awesome!

A good middle-ground is to combine Ethernet backhaul mesh networks with powerline adapters to give them a faster wired backhaul without running cat6 everywhere. Sadly results will vary depending on the quality of the power wiring of your home.

I changed the channels for 2.4 and 5 to ones that were not being used around me and so far so good. Thank you

Thanks! This was the perfect guide for trying to mitigate our speeds and connections in my apartment's densely populated wifi signal area. Those Ubiquity things are rad!

I love these videos on network stuff. Great job

I'm a huge fan of the lighting in this one Ben. Killed it.

Great video and enough information to not be overwhelming to someone just being introduced. I deployed a UniFi system in my home with a UDM Pro and cameras. It has been a great home system so far. I just had to spend a few nights in the attic running cable.

This was a great video. I rarely comment or like anything on KZfaq, but I had performance issues like what you described and the tips you gave are how I fixed my home network. I just wish this video existed 6 months earlier because it would have resulted in a lot less trial and error and expense from me trying to fix things.

Networking videos are so underrated love this.

Hey great video but you did some shortcuts. First, even if we have 13 channels available in 2,4 GHz spectrum, only 3 are “overlapping-free”. So channel 1, 6 and 11 are the only 3 you can use without interfering with each other. So by using channel 5 you have to consider the interference of channel 6 and even some from channel 1. In the 5GHz spectrum every channel are overlapping free. Like you said, setting the transmit power to the maximum possible is mostly a bad Idea. First you need to know that the communication have to be done in both direction, so if you set your Wifi Access Point to 23dBM but your device can only send up to 13dBm, you will may be see all Wifi bars on your smartphone because it receive the power but like I said, he need to reach back the AP. And it have 10dB less power (almost 10 times less). If you ever had experience at some point having a good connection on your laptop but not on your smartphone it is probably due to that. The laptop usually have more power. The other problem is with higher transmit power you have a fake because not useful bigger wifi cell around your AP, letting think your device everything is fine and not try to find another antenna. That behavior is called Sticky client and it’s one of the biggest problem when using multiple APs. Another thing you didn’t mention, mega wifi is really more advanced then the standard repeater. With a repeater, you will only have accès to a split of the bandwith to retransmit it. So if on your ISP router you have 9 clients and your repeater, the repeater will only have 1/10 of the total bandwith to share with the clients connected to it. Mesh Wifi on the other side use a specific connection instead of just retransmit the Wifi it received and so allow a higher bandwidth because it this connection is not shared with other devices. The most advanced Mesh solution even allow to use all APs in the neighborhood to get the maximum throughput possible.

I set up a TP-Link Deco mesh network at my in-laws 2 years ago, and it's been rock solid. It's even dual natting, and I have no issues getting access to internal items remotely.

Big classic CNET vibes from this one! Really well done I hope this helps the people who need it

Congrats on 1mil subs. Great video and content

This has been super helpful for me. Great research and presentation.Thanks!

Great advice. Going to a multiple AP high density wifi solution really is pretty dang nice. I went from being happy when I get over 100Mb to being sad when I get less than 300Mb. Another thing I've found is that if you get equipment that will let you use DFS channels, and ideally will tell you when it has to power down for RADAR, the DFS part of the spectrum is a ghost town.

thanks for putting out these videos it helps to explain to folks who dont understand

SUPPPER HELPFUL MAN! Thank you. I have two internet providers in my apartment (I do this if one goes down). I can see what channels everyone in my area is on.

Where was this video when I was a teenager trying setup up Xbox 360 and Nintendo DS? This man just blessed y'all.

Another excellent video Quinn, top quality all round.

Never ever pick channels other than 1, 6, or 11 on the 2.4ghz band. This is a huge problem that not only hurts you but everyone around you. If you pick channel 5 then not only are you still incurring interference from people on channel 1 but also people on channel 6.

Yay..... My new year's gift is here.... A snazzy video

I watched this video in 240p to get in the mindset of someone who really needs this video.

Great video. Easy to understand, informative and very useful. I downloaded that app and it's the best one I've used for that function. (I've tried a lot of them.) Good work.

This was so helpful. Thanks, Quinn!

Love the detailed explanation. I’ll be downloading netspot tomorrow!

One the 2.4ghz you really should stick to channels 1,6,11, you can look up overlapping channels and co-channeling to see why.

I Absolutely love this video and want for more people to watch this. I work for a Larg ISP in Canada as a field tech.(installation & repair)for DSL/Fibre/& wirless home internet. We get lots of calls for slow speeds Of course lots of factors can be come into play. Most of the calls I do ls customer education about most of what you talked about. It surprises me how many people just expect everything work without knowing how it works.

Eero Pro 6 has wired backhaul also and works very well. I have 2 wired and 1 wireless and I get a pretty good 600-800 MB of my 1GB on wireless. Great Video!

As always just excellent Snazzy Man 😃

this video was absolute fire.. thanks a lot my dude!

Thank you very much for such a great explanation of Wi-Fi. I have a 3 piece TP-Link Deco M9plus with ethernet backhaul. It works very well. I have a couple of devices that are Wi-Fi 6, so I installed a Wi-Fi 6 access point, but I didn't notice a difference in speed even though I saw the Wi-Fi 6 logo appeared on the phone. So I returned the access point.

Also DFS channels if the transmitting device supports it, makes a world of a difference in congested areas. Overall a great explainer, thanks!

Thanks for making this video snazzy:)

The performance of wireless adapters in your network can't be underestimated as a factor in your satisfaction with Wi-Fi. Even something as simple as drivers can make a huge difference.

THisis one of thge most important and helpful videos of its type. THanks so much for doing this. I have a little bit of a complex situation and this really helped. Iahve moved to WIFI6 and have already felt the benefits. I get 54MBps from my provider and even with over 20 devices on the network and 2 floors away from my router on the 5ghz network I get 52MBps at my PC by applying some of the tips here. Really helpful. Thakns again.

Thanks for this highly informative video! As a high school student it helps me a lot, Quinn.

It was really awesome, informative and helpful video, even for non-tech guys! Keep it up and thanks for the video!

I actually knew almost all of that I was waiting to hear something that was going to blow my mind... But for most this is be all and end all solution... Really educational amazing videos

I tried to like the video multiple times… very well done

woa this actually helped a lot! we live in a 2 floor house and wifi reception is terrible upstairs, also, our company's router broke so they gave us another one thats actually worse and much older and we had no idea what to do.. we'll definitely consider getting a new router and using the old one as the modem and forget aobut all that

Happy new year guys

I really love most of your content! And even more than that, this is a problem I need to solve. But honestly... I got so bored learning about packets! I plan to come back and watch again later. Eventually.

Where was this video when the pandemic started and I was trouble shooting everybody's home network for them? Lol This was a great explanation. Thank you so much Snazzy Labs!

It would have been key to point out that there are only 3 non-overlapping {1,6&11 for 22 Mhz channels} channels in 2.4 GHz. If your neighbours don't care and set it to automatic then this advise goes out the window. This is currently not a problem in 5Ghz as the channels are already spaced ...there are 25 non-overlapping 20Mhz channels or 12 40 Mhz channels. If your tinkering you ought to come across this advise.... Also you lose close to 50% of bandwidth due to overheads in WI-FI. So those advised speeds on your router cut them in half ...

Pretty good video, as usual. Although, I'm a bit surprised you didn't cover the channel width (20/40/80 MHz) setting at all. That one will directly influence the speed.

Damn this is well researched and very informative! That's why I watch Quinn's videos.

It's really interesting to see the difference between countries. Here in the UK, there is only one company that does cable internet, Virgin Media. Almost everyone else is on DSL, which here is regarded as the norm. People are slowly being upgraded to fibre though.

My set up is baller as hell for a home. 1000 down /1000 up fiber to the house, wired ethernet to every room with every room having a hard wired access point. 900mbs over the air anywhere in my home.

Great video.None one the networking experts on YT don’t usually explain these details

DSL might have a bad name in the States, but bonded vectored DSL can do speeds of over 200 megabits per second within the neighborhood of 60-80 megabits up. Not just living in the 90's :)

Surprising after going thru this video, I made some tweaks on my router and guess what, I got good WiFi speed again! This is a very good New Year gift!

you're a legend Quinn

I have Google mesh and it's been great for me and my family. Our entire house and separate garage get coverage from 3 mesh points.

FYI in the UK lots of places still use Rj11 for VDSL (FTTC) Broadband that can offer customers speeds of around 70 to 80mbps was designed so they could bring fibre to a box on the road then hook up your existing copper line to it as in the UK especially Cable aka Coaxial wasnt rolled out in that many places, like in the city I live we have no Cable Coaxial even available, so unless you can get fibre your stuck with ADSL/VDSL over RJ11.

Great video! I think most people can grasp it. A tip I’d add is to not connect every device on WiFi if it can be connected by ethernet cable. Printers, desktops, and even laptops when at a work desk can be removed from WiFi altogether. Laptop doesn’t have an ethernet port? Get a USB to ethernet adapter.

21:35 Because of “Carrier sense multiple access/collision avoidance” (CSMA/CA), Wi-Fi routers will automatically select channels 1,6 or 11 to coordinate who’s yielding and who’s using the same channel at which times. Using channels that aren’t the same with neighboring Wi-Fi will not coordinate and while having them overlap with each other will end in more noise and interference (like what you did here by choosing channel 5) It’s still better to set your channel and channel width to auto. But if you’re still having problems, then choose either 1,6, or 11 (whichever has the least amount networks using them) as it’s better to avoid overlapping at all times

I live in Australia in a city and we still use copper (telephone) cables. Our NBN is the biggest copper based data network in the world. Other first world countries have moved on to fibre/coax, 3rd world countries use mobile networks - nobody has their own wifi at home.

no, this is actually the first video i click I missed your videos, man

Sometimes it sucks because there is a grid outage which can last for months so you’re better off switching isp

Amazing review, as always.

I have that same advent calendar! Had it since I was a kid :)

Actually since I’ve been subscribed to Snazzy labs for years when I opened up the KZfaq app it was on the front of my Home Screen and it WAS the first video I clicked on 😝

21:55 Be aware of channel overlap if you choose a non-standard channel like channel 5. You’ll be getting overlap from ch6 and a little from ch1!

A really good tutorial. My network is very complicated and in the end going back to a single point had better performance.

I've spread over 150mt of cat7 ethernet cable over my house and use a bunch of tplink deco mesh as access point because they can support also like an access point Nice video!

Great video! Thank you! My router offers the option to combine the SSIDs of 2.4GHz and 5GHz. Currently I have them as separate SSIDs, do you have a recommendation?

Also made by Ubiquiti is the AMPLIFI Alien which is expensive, but it’s by far the best wifi router I’ve ever owned. Great range and fast speeds.

Quinn: “May even be an RJ11 cable if you’re stuck in the 90s.” Me: *Cries in UK*

“You’re devices can’t talk directly to a modem.” Yes they can (and I’m not talking about combo devices, I’m talking about single modems). You can only use one device tho, and it’s going to be via a direct Ethernet cable, or if you time travel backward, a modem pci/isa card for your PC).

I work for an ISP and I wish every single one of our customers would watch this Video. I sent it off to one of our trainers to take a look at and see what he thinks to maybe incorporate it into our training program to help some of our less techy call center people understand how the internet works and how WIFI works.

I’m a simple man. I see a snazzy labs video. I watch.

I have three Eero mesh routers. In my two floor home, I have one Eero in my attic, one in my living room and one in the basement. All three are ethernet "backhauled." My wifi signal is spectacular. Even if you think it's a hassle to wire your home with an ethernet line, the weekend of work it will take to run a line from the cable modem to the deadspots of your home where you will place your mesh node is worth it.

Happy new year everyone! 👍🥳

We use telephone lines here in the uk, but we usually include an adapter with our modem-routers.

For everyone watching: please don't use channel 5 on 2,4ghz but instead leave it on auto if you're not sure why Ch. 5 is a very bad idea :/ Except that, it's a great video

The cheaper mesh networks can also be directly wired instead of connecting wirelessly. It just depends on which nodes you buy.

Great video. Ever since I got a TP Link mesh system with a wired backhaul, my wifi has been a lot more reliable. As a word of warning, it can be possible for people to look up a set of wifi network names and get a GPS coordinate out of it, I think Google has a service like this. It might not be a good idea to have a big list of the networks around you if you don't want your location available.

My mom has the same advent calendar as you! Never thought I would see another one

I've seen so many times that for 2.4GHz you should only ever use ch 1,6,11 so you're not overlapping with other channels but living in two different apartment complexes with tons of networks set to auto and doing tons of tests, I've found that to not be true. Using a non standard channel like 8 instead of 6 or 11 has always given me better speed and consistency.

A fiber-to-the-home gateway device will not contain a modem, as there is no modulation/demodulation necessary to pass data to/from WAN. All that is needed is an ONT-optical network terminal-to convert optical signals to electrical and vice-versa. This may be combined with a router or kept as a separate device. The router will likely need VLAN capability to properly tag traffic, and possibly also PPPoE login capability, both depending on your ISP. Still, there's no modem in the mix.
