My AP upstairs doesn't work well, hardly at all. I've run through all the basic trouble shooting steps but generally the AP disconnects and drops signal. Sometimes it comes back up sometimes it reboots then then reconnects.
Can you share your AP support log and direct DM to me or share the AP version, is it standalone or vSZ managed or Unleash and what other model APs you have ? Alternatively you can also open up a case and attach the logs to analyse and suggest further action :
