does it still work today? i thought most devices were pactched. but would it work if we got the packets from multiple devices if they all try the handshake ? idk maybe i should research about this

When it comes to refraction: Generally how wide is a wave length ? You mentioned a filing cabinet 🗄️ while the display gives an example of a roof top ? Also what is the size difference between that of say 2.4 opposed to the 5ghz [ if you aren’t sure of exact dimension- Maybe you’d be able to say which is wider over the other (2.4 or 5). ]

I hear you 🤚🏾

What are the job opportunities for Wi-Fi these days? I'd love to earn the CWNP certs but the job outlook seems slim...😢

Re the 1 Mb beacon on 2.4 GHz. Does that also apply if the AP is not configured for 802.11b? I try to configure for minimum 802.11n these days.

The discussion about byte size takes me back to when I was a computer tech working on the old mini computers and mainframes in the 70s & 80s.. I used to work on tape stands, with 1/2" tapes. They were available in both 7 track (6 data bits + paritiy bit) and 9 track (8+p) versions. Most of the ones I worked on were 9 track, but there were a couple of 7 track drives too. They were used to interchange data with a UNIVAC system, which used 6 bit bytes. Beyond the tape stands, everything else I worked on had 8 bit bytes.

I keep coming back to this video year after year. Thank you CWNP.

Great sharing. and could you please share the packet captures either? Thanks

thanks to this video, i was able to succefully pass the past exam questions i’ve been practicing. I got he past questions from Leanology World for free , they gave me official CWNA 109 study guides for free as well but those study guides where not enough for me, this video tutorial was able to put the knowledge that i got from the study guide into perspective. ❤ thank you a much for making this tutorial video ❤

Needs to be known more

You had me in the first half there. I really thought I clicked on the wrong video about testing the wireless pens.

Did you read all the T&C's ???

Great talk, thanks for posting.

I can hear 6ou

Is this channel dead?

Why is your eLearning resource package for your entry level certification $325? It is pre-recorded videos and quizzes. You have a study kit with an exam voucher, practice exams, and PRINTED (mailed to you) Study guide for $225, but I have to pay an additional $325 to watch videos? Seems odd, especially for such an entry level cert. I have 2 employees that I was planning on assigning your certs all the way through CWSP, but if simple video learning packages are going to run me $650 dollars ON TOP OF the cost of the voucher kit for JUST the CWS, we'll have to go a different route.

Hi Marcus, Thanks for this short and meaningful explanation .I have one query when user enters wrong password then at which stage it will validate this and authentication getting failed.?

These are great, but if you add animation when explaining some of the concepts like interference etc. these videos would really take off

Is there a Part 5 of this video series? l RELLY WANT TO LEARN MORE.

Here we are six years (!) later, the entire industry knows about it, USB 3.x and 4 are getting both more sensitive to and bigger sources of interference in more frequency bands, and yet nobody has considered fixing the obsolete USB plugs/connectors to a design that provides adequate shielding. USB is everything you want, as long as that's a simple USB point-to-point and nothing else around it. Unfortunately, merely looking behind my desk shows how removed that is from reality, and I don't even consider myself a power user - just an average guy trying to get his stuff to work stable.

Any pre-requisite required to do CWISA cert?

thank you

My old windows tablet has a usb 3.0 port, when a portable hdd is connected in usb 3 mode the wifi is completely jammed. I had to switch the hdd driver to usb 2 mode to get the wifi working again.

Thanks a lot ! Thanks to your video, i resolved my problems : my new wireless set of mouse and keyboard was struggling all the time when the receiver was direct plugged on the usb 3.0 ports. So i bought USB M/F about 30cm ( or more / less ) extension cable to deport the USB receiver and all is working perfectly ! People, deport your USB receiver even a little bit you will see big improvement if you are using USB 3.0+ ports.😄😁😄😁🤗

No wlan ... its wifi ...

Love you Keith. Always fun to hear you and see you .

Is there a certification book?

I bought a new mouse from Razer, the whole evening I could not understand why the connection with the computer was constantly lost. It turned out that I was using USB 3.0. After the video connected to 2.0 and it all worked

Great video sir!!! Thank you for your community service!!!

Kudos 👏 !!

I can't understand English. So does WiFi support Full Duplex?

Thank you for such a concise and brief series🙏

What if the pre authentication is disabled?

Cell company is already started home internet and wifi will be obselete in 20 years

I dont get it, looks like a good idea but no one is building this, I assume its open source ?

Thanks Peter it helped a lot

thank you for the informative webinar:) I have a simple question. Where can I find the reference of the allowed channel numbers? (In FCC, I could find only the frequency ranges allowed, not channel numbers)

If anyone reads this can they please direct me to radio frequency training for tower climbers I'm trying to find a review course online while I'm waiting for my own industry to provide me with the class for some reason I cannot find anything online

This is the end of freedom as its known.

Excellent explanations, thank you for sharing.

this exactly like nebero

Great presentation from Peter as always but absolutely terrible cameraman and director.
