A few years ago while working on down access points. It occurred to me I should track the resolution and trend this data. I wanted to know the top causes for down access points.
To my surprise an interesting trend started to develop.
5% - Access point failure
40% - Ethernet cable pulled from switch port
5% - Switch POE issue
30% - Down due to construction
5% - DHCP issue
15% - OTHER
Based on the data we collected 70% of our issues revolved around folks pulling our access points from switch ports to make room for other devices and construction events. Armed with this data we worked with desktop and our project managers to help limit the impact to our wireless user base.
You can trend other data too. Perhaps you have application folks blaming WiFi for everything. Trend this data and if its not WiFi start to track that data.
Data is powerful in the right hands.
