I have recently started to get a lot of âCoverage Hole Detected for AP03 whose Base Radio MAC isâ¦â¦.. Number of Failing Clients 1â across my company site, a couple of mins later the trap log reports âCoverage hole cleared for Base Radio MACâ¦â¦â When the hole is created a client is disconnected from the network causing them problems. I have searched on the Internet, but cannot seem to find a great deal of information on this issue.
We have 2x WLC 4402 (Primary & Secondary) running software version 188.8.131.52 with 24 Access points model AP1020 boot version 184.108.40.206.
There have been no changes recently to the network, no alterations to the building or impact from companies either physically or via RF.
Can anybody provide any answers or point me in the right direction to investigate further.
