I've been looking for a video to share with friends about WiFi; I'm definitely sending this... Thank you...
Same here. Great vid that teaches it way better then I could.
This is such a beautiful explanation.
appreciate you taking time making this vid
Great work on the video! The information was solid and it was nice to get refreshed on WiFi standards! Thanks for sharing!
What an incredibly detailed and easy-to-understand explanation! Thank you so much this helped me out a ton!
It took a few times viewing this but I think I understand now. Thank you!
Studying for the CompTIA A+ exam, all the books and other videos on here didn't sum up WiFi anywhere near as well as you did in this video. Thank you!
Solid explanation. Couldn't get it anywhere else.....Thank you!
Omg, you explain very well, I was always asking my self what are these codes, and I even searched but never understand, but with your videos, you really explaining very well. Keep the good videos coming, great job 🙂
Great video man! About to take my A+ Cert and needed a refresh!
Thank you for a very detailed explanation. Loved it.
Great to the point video! Thank you
You definitely had to be a visiting lecturer during my engineering days
This video is amazing, thank you!
Wonderful video! Thank you so much for the easy explanation!
I just bought the exact same router that you mentioned you have. I had severe signal conflict issues I think, we had a fast connection with a good N router but everyone on WiFi was struggling. Even with everyone connecting at only 2.4ghz on the new Asus router all problems have evaporated, devices close to the router I connect at 5ghz. I love the gigabit LAN switches as well, takes full advantage of my Intel gigabit LAN on my motherboard. I can't even express how huge an upgrade it was from a high quality Belkin N router to this RT-AC68U. It's epic, multiple 4k streams going at once, console gaming, pc gaming, and file transfer over the network to/from my NAS and never an issue. Great video it's nice to see exactly what it is about it that makes it so much better.
Thank you so much man....this is great!
Very good explainng ! thanks from Argentina !

Cool, thank you!
Thank You!
very useful. thankyou
Well done
Thanks, man
11 mbps is still faster than my ISP can supply. I hate Verizon.
same with optimum
Which gives better speed? 802.11 b/g/n or 802.11 n?
802.11n
First there was 802.11. which effectively became 802.11b after 802.11a was added as it came first it was already in use.
Which is why it was more popular.
So effectively 802.11a came two years after 802.11b although 11b did bring a few incremental improvements.
But as the two were comparable it had a few years head start.

802.11ax (Wi-Fi 6E)
802.11be (Wi-Fi 7) ?
Your a legend
Great explanation. Tech made simple for those of us that are trying to learn and are not tech savvy. Thank you so much! However, I do have a specific question I hope you can answer, in your opinion, would the Lenovo Tab P11 Tablet, model # ZA7R0036US, with a 8.02AC(1x1) which Lenovo claims is a 2.4 GHZ tablet but would it be able to connect to 5GHz? Thank you, JD
Siempre tuve problemas con el wifi no me reconocía el router , la conexión era lenta. Mi error era tener de fabrica la Wireless en b/g . Pero luego de ver este video y entender que debía utilizar una red 5Ghz para el Wifi y 2.4Ghz para el bluetooth dejaron de hacer interferencia y sirven todos los perifericos sin latencia con la configuracion Wireless g/n me reconoce todas las bandas y ahora tengo 200Mbs de banda ancha. Puede que no me entiendas el idioma pero salvaste a un soldado que se daba por vencido, con CONOCIMIENTO mil gracias.
Thanks, great explanation
You are welcome!
Great !!!
Why am i interested on this lesson more than all my lesson on my school
Big brain, thx
ditto to the comment below. Very helpful explanation.
So what is the best or recommended mode for this?
Great video - I was looking for a more technical explanation and this provided the level that I was after. I can't get excited about the "ac" or "ax" or whatever the latest is - a mix of G and N provides the bandwidth I need for wireless connected devices. For a lot of folks the limiting factor is going to be your ISP - not your wifi.
Life saver
Awesome
Damn your explanation it too good
There are three reasons that you can't achieve maximum speed.
1. the overhead in each packet(preamble,header...)
2. The time waiting for ack.
3. Finally the CSMA/CA mechanism(DIFS,SIFS). that's describe how devices share the same network.
so, even though the signal level is pretty good, you will never achieve 6.75MBps with 11a due to the facts I present.
Nice tutorial BB! What about ad? Can you share your expertise on that one? 👍😀
I'll be skipping ad and going to ax. ad is great and offers extremely fast speed but its range is absolutely terrible. It's designed for devices in very close proximity as in within 10 feet. That's why ax is becoming the new mainstream standard. The ax video will be up shortly.
My router settings have mode selection drop down of all the frequency mode, there is also combination of all the mode, is it advisable to select the combination of all the mode? Thanks
I have a 1gig connection and on lan I pretty much always reach full potential 900+Mbps but on my Android device which has a 802.11 a/b/g/n chip I max out at about 110 Mbps, directly a few cm next to router and tested on many servers. Shouldn't I be able to reach easily 300-600 Mbps according to your definition?
Thanks for the explanation. I didn't catch one thing. Can I use wifi router/repeater which is AC with devices that have 802.11n ? Backwards compatibility ac => n
I did understand that it is not backwards compatible with b and g because they use 2.4 GHz frequency
Yes. AC routers broadcast 5Ghz but typically have N technology builtin to broadcast 2.4Ghz to other n, g and b devices.

what do you think about 3 antenas (btw i have for now classic normal router and i have 3.47 mbps so if i would buy that router with 3 antenas it shows that it should have 600mbps-1300mbps soo can you tell me that if you think that is true and how big the internet would be on ps4 if i would connect it with LAN cable with wireless router with 3 antenas ?? that are my questions i would really like to know. Thank you.
What if there is written "802.11 a/b/g/n/ac"? It's written in the ps4 specs and I'm wondering what does it mean. I mean, all this letters are written together as if it was one sign.
It means it is compatible with all of them.
@@Babblingboolean Thank you ;3
tx Beam forming is introduced in 802.11n
Naisuuuu
Great video! Anyone know why in my laptop keeps jumping to ac and n (2.4ghz) but N internet is so low. Thanks
Hi, thanks for a great video. Just in the last couple of days I added three plug-in dual band range extenders to my 802.11n router on a wireless home network. But, the extenders could only find the 2.4GHz frequency. Any ideas why this might be?
I doubt it's the case but do the extenders even support 5Ghz signal?
Is your 5Ghz signal active within your router?
Is your 5Ghz signal active but broadcasting a hidden SSID?
It's hard to help without being there, you should call the manufacturer technical support.
@@Babblingboolean Thanks for the reply.
The router is a Huawei HG658c operating on 802.11n wireless protocol.
The extenders are indeed synchronous Belkin AC1200 Dual Band AC Wireless Range Extenders with Internal Antennae.
I had a technician for Belkin walk me through correct set-up of the extenders over the phone, so I will contact my ISP as you suggested regarding the router.
Perhaps the 5GHz signal is inactive or using a hidden SSID in the router. I simply don't know how to check or adjust those settings.
Thanks again for your reply which I appreciate.
UPDATE
Having just contacted my ISP, they were able to tell me that the Huawei HG658c router, (which usually operates on 801.11n), provided by them with my Home Broadband package was in fact configured to operate on the single
frequency of 2.4GHz alone.
Such practices are not unknown with ISPs to provide different packages at different subscription rates to their customers.
