Weird Issue here: Cisco 8510 on code 8.0.133.0. I have read of at least one other user having this issue a year ago, but no resolution. I have 3702i access points and in some areas, users call in with voice quality issues or other connection issues and end result is the area there is a problem the 5 GHz on an AP is not working. Clients don't associate to that AP on 5 GHz and have to hit another AP further away. There are no alerts or signs that 5 GHz isn't working, but I have found several AP's in several areas with this problem. The fix is always to reset the AP from the controller and clients on 5 GHz connect right up. Any idea why this happens? I will console into the next one to see if something shows up, but what should I expect to see? I know these AP's have an uptime of 200 days or more. Any help would be appreciated and if anyone else has seen this, let me know. I am in a healthcare environment and can have up to 35 AP's on one nursing floor.
