This is not directly a LEDE question but my environment is LEDE / OpenWRT firmware with batman-adv layer 2 mesh.
I would like to improve my ability to diagnose issues with wifi. For example if clients are having performance problems with their connection, or simply cannot connect, all I can currently do is confirm services are working (such as DHCP), check the logs for errors, confirm singnal strength and IP connectivity or reboot the router (which almost always works ). However, it always bugs me when i reboot the router since I never actually learn what went wrong.
My question is not how do I do that My question is can some of the experience folks her give me a starting point. I've tried to research this on google and I find the information is either too simplistic (reboot your router or update your firmware) or too low level for my current knowledge (802.11 specs or driver level).
I think the lower level is where I need to go but I'm looking for a more palatable path than reading the standards docs or going through the driver code. Any favorite urls, resources or tools folks want to share?
Thanks for reading.
