WiFi Troubleshooting

WiFi is complex and it can break in a great many ways, but the approach to troubleshooting anything is basically the same every time. We compare what we see happening, with what we think should be happening in a correctly configured and well optimised environment, and we make changes as necessary to close the gap. Clearly then, possessing knowledge about what good looks like and access to good diagnostic data, are both key to effective troubleshooting. In this post I look at common ways of remotely gathering that diagnostic data across a range of common Clients and Networks, such as Cisco, Meraki, Microsoft Windows, and Apple.

It’ll take me an age to do deep dives on all of these things, so for now this is a post containing links to useful troubleshooting resources. The content within these links is essentially things I just know, or resources I link to frequently to help me do my job.
