Great vid. Thanks for the useful info and more tools to play. For me the best spectrum analysis is Cisco spectrum expert which connected to Cisco AP in Spectrum analysis mode. Better results with directional antennas. The best tool for packet analysis is Omnipeek which connects to Cisco AP in sniffer mode.
I love your videos, Tom. I hope you do them more often as I am trying to learn as much as I can and your content is so good! I had just purchased Acrylic WiFi Professional today and an adapter so it was very fortuitous that you put this video up. :) I am curious, though, any tools or advice on how best to decipher chromebooks disconnecting and or stuck on a processing screen when a classroom full of students is trying to access a graphics-intensive test? I have the packet capture, just not sure how to look for what is causing this problem. Thanks in advance for your time!
It would be good to know the signal characteristics of that client as opposed to the others in the classroom, but that is hard with chromebook. You could look for retries originating from that client or from the AP to that client. This will give you a feel for interference issues. Additionally, look at the airtime utilization on the channel. That is, of the available airtime, how much is in use during the test? If it is about 70-80%, it could well be a capacity issue. There is, of course, more to try depending on the tools you have, but this is a good start.
These new webinars are much improved, mainly due to informative content for real world deployments. cannot wait to watch the next.
