Great video! Just wanted to let you know that I passed my A+ exam last year and it was so satisfying and brings encouragement to go after the other CompTIA courses.

I want to sincerely thank you for doing this for the world. Because of your help I am able to better mine and my families life

[lancelyde]

I love when I can recognize these technologies in my daily life! It makes learning more fun. I realized library books use RFID stickers to track the books! I remember seeing the stickers on the backs and never knowing what they were. Now I know!! Yay!!

[MyronVsTheWorld]

The 15+ minute videos are always the toughest to sit down and digest😪

[chinoyomaji]

This, so far, is the one module i can understand the most thanks to my few short months of working at spectrum

[kurrizzle]

That blue Linksys wireless G router lives in my head as *the* OG router

[RPGyourLIFE]

Sincerest thanks and love to you, Professor. You are streamlining my success.

[TomTreutlein]

Thank you for making all of these easily accessible videos. They are very helpful.

[Xtrahtsuce]

Thanks for helping us study ur the goat

[BigGlokk]

Memorizing the PoE standards before this video is helping me remember these lol

[douglasduda]

I remember a Linksys router we had would hang when the microwave was on...lol...It was annoying...

4:39 Professor Messer mentions that an access point(AP) can be upgraded while explaining backwards-compatible. Does anyone know what he means by upgrading an AP? He explained APs in Network Devices. I understand an AP to be a device that is directly connected to a wired LAN and provides wireless connections to other devices. Is an AP capable of using softwares and he means upgrading these softwares?

[djschannel]

Awesome!! 🙏 thx for the great vid and awesome explanations

[pissedputin]

Will the exam quiz us with the different speeds of the different standards? Or we will be fine if we just memorize 802.11a, 802.11b etc..

[jasonburrs]

Do the course notes have some type of glossary to define what the acronyms in the video represent? Sometimes it's difficult to follow the videos when unfamiliar acronyms are reference.

From a video standpoint it conserves time I understand but from a learning standpoint it complicates the ability to process the info provided.

[kurrizzle]

Not trying to cause trouble, just thinking out loud, but what's really stopping people from using "unapproved" frequencies outside of 2.4 GHz and 5 GHz? Who would notice? What would it disrupt?

[seanturner]

Has anybody found a good way to memorize the characteristics of each standard? Should i just use flashcards?

[dumplingsuwu]

54 mbps back in 1999, yet my isp here doesn't even provide more than 3 mbps todays irl 😂

[ClubMusic]

Professor Messer, as help desk are you going to be asked to install an antenna or can the company bring in a third party to install it?

[SupaMan]

B slower than A will never make logical sense to me 😂
