I just left a job site where I failed to explain to a customer why their old video doorbell would not connect to their new Eero Pro 6 Network. Thanks to this video, I can now more clearly explain that in the future. Thank you!

[JohnDoeAKA]

I cannot believe how simple this actually is, you are appreciated brother man. Please do keep it high

[elainepotgieter]

Very helpful. I'm busy shopping for laptops & some companies were giving 802 specs which I didn't understand until I saw your video and realized it's just wifi 5 or 6 etc. Thank you!

I am moving form IOT to WIFI development, this video is the best simple explanation on wifi standards I have seen

802.11a & b were released at the same time. 802.11g uses the exact same modulation method as a, but it also provides b protection, as b cannot understand g, so g has to transmit some b before shifting to g, if any b signals are detected. This is what causes the big performance hit to g where b is also in use. The missing letters are for other WiFi specs, but not radio type.
BTW, these days, you should never use 802.11b devices due to that performance hit. Also, it's only capable of using WEP encryption, which is not secure.

I have Netgear ax1800 wifi 6 which is 802.11ax standard. In order to support that on my desktop PC, I upgraded latest wifi card(wifi 6support). The network speed is kinda hype because internet company are late on fiber optic Advancement. That's why the main thing is wifi infrastructure. No matter how much you upgrade personally, it doesn't help the Internet speed.

Can you explain why a tablet can connect with Wi-Fi 4 or Wi-Fi 5 router using 2.4ghz but can't connect to a Wi-Fi 6 router using 2.4ghz while another old mobile phone can connect to this Wi-Fi 6 router using 2.4ghz? The Wi-Fi 6 router 2.4ghz has tried set to support 802.11b/g/n or 802.11a/b/g/n/ac respectively

0:11 - "can you imagine a life without wireless"?
Uuuhhh... yes! And honestly, the computer scene of the beginning of the 90's, with BBS'es, was way cooler than today. In those times, everything was just same like the current "darknet". Totally unregulated.

[abdulwafi]

im still use 802.11a on my wifi adapter today . Give enough bandwith for video streaming and gaming. without ruining others experience within same networks

[jnzooger]

This is a decent standards look, but I feel it’s missing some. Like extreme G that did 108Mbps or draft n.

What's the difference between wifi6 and wifi 6 certified?
