Daily Pattern Wifi Dropouts on Cisco Air 1142N with Apple Mac devices
I have a network of Cisco AIR-AP1142N-E-K9 running with Version 15.2(2)JB, wireless access points, for the last 1 month users in a specific area of the office floor have complained of WiFi Drop out issues that last for around 5 to 10 minutes, they all use Apple Mac devices with a mixture of Macbook Airs and MacBook pros.
From analysing the access point logs I have noticed the following (this is an example for one client however similar pattern of logs for all clients affected)
Oct 7 16:09:32 10.1.4.43 65964: Oct 7 15:09:32.209: %DOT11-6-DISASSOC: Interface Dot11Radio1, Deauthenticating Station b88d.1213.14b6 Reason: Sending station has left the BSS
Oct 7 16:09:33 10.1.4.43 65965: Oct 7 15:09:32.330: %DOT11-4-MAXRETRIES: Packet to client b88d.1213.14b6 reached max retries, removing the client
The access point seems to be having difficulty communicating with the client and therefore removes the client, physically the client has not moved and the impact this is having is that they cannot access any network services
Word carried out
I have been investigating this and thus far based upon other threads on these forums and suggestions from Cisco documentation I have done the following
Diable Ciscro Aironet Extentions on Radio 1 and 0 by using
no dot11 extension aironet
Swapping the Physical access point with a new one with the same config and firmware buy on different frequences
Carried out an analysis of the Wifi signal during the daily drop out time and I am not noticing anything of interest that would indicate why users are facing a daily drop out at 4pm.
