Troubleshooting Wireless LANs can be a real pain… because ANY problem an end user experiences on their Wi-Fi device is by definition a “Wireless Problem”.
Years ago, Lee Badman posted this great graphic trying to help visualize the many facets of troubleshooting Wireless LANs… and titled it “The Soon To Be Famous Cocktail Napkin Wi-Fi Big Picture”.
Well Lee, sorry it has taken me so long to help get your picture famous!
This was the starting point of a new Troubleshooting Wireless LANs course I was developing. But after a lot more research, talking with scores of other WLAN Professionals, alpha testing, beta testing, and holding Train The Trainer sessions… here is the result of what Lee Badman started.
36 ‘Bubbles’ of distinct groups of items that could have problems, plus one BIG item, the big RED BOX on the top left side representing the RF Medium… and there are even more things that can and do go wrong in that group.
We then worked with other WLAN Professionals to get details and specifics of what might possibly be wrong in any one of these bubbles. We have so far documented over 400 individual items what one might need to understand, test, and perhaps troubleshoot just to solve the “Wi-Fi is Slow” complaint!
Keeping with the ethos of WLANPros.com – we are freely offering all of these to the community!
