Understanding Wifi Bands

Understanding Wi-Fi bands is vital to understanding when to use 20 MHz versus 40 MHz versus 80 MHz channel widths. It's also an important prerequisite to understanding Wi-Fi channels and channel width.
Every wireless environment is different, and you need to tailor your equipment to the conditions. With 2.4 GHz, increasing your channel width often isn't worth it, and you should stick with 20 MHz. Conversely, with 5 GHz, increasing channel width can improve performance, but there are tradeoffs. With 5 GHz, if you don't have to worry about interference and all your client devices support it, go with the highest width available.
By understanding the fundamentals, you can more effectively select a configuration that works best for you. While there is no one-size-fits all answer to the "20 MHz, 40 MHz, or 80 MHz?" question. However, understanding 2.4 GHz vs 5 GHz frequencies and the tradeoffs between non-overlapping channels and speed goes a long way.

Great video as usual

If you get a dislike it has to be a miss click good information most of us should take the time to know.

[@kawikacraft8161]

So what is the best channel to use for 5ghz? 36, 40, 44, 48, 149, 153, 157, 161 165?

Thank you. I have been looking for someone to explain to me clearly channel bandwidth and how we got 14 channels in 2.4 GHz. Question: what could be the reason why connection is lost when moving from one WAP to another with the same SSID? Am I allowed to go access the router provided by the ISP for wireless configuration issues? Is the demarc the router or the coax wall attachment? Sorry, beginner in networking. Thank you again.

Put the different WAPs on different channels for less interference. WAP1 on 1, WAP2 on 6, WAP3 on 11. Also, reduce the transmission of the signal so they the signals don't overlap two much. If they overlap, devices may have a hard time disconnecting from one and connecting to another.

Why is 20 MHz used in 2.4 GHz and not lower bandwidths?

[@xllAyato]

Because of the throughput would become to small I guess.

[@francocastilloAR]

@@xllAyato It may be, although there are other factors...

[@gamecubeplayer]

​@@francocastilloARthat's also what i told you many months ago

[@droy333]

Probably should refer to Wireless Access Points rather than Routers in your examples.

[@DCUOCover]

why would he WAPS are used to extend the range, a wireless router provides the Internet/Network connectivity so he is correct

[@vairo-]

0:40 I think there's a mistake there, each 2,4GHz channel is 5MHz long, not 20.

[@DCUOCover]

lol you are wrong
