Hello


I have a Problem with a customer WLAN. The customer has a Aeronet 1130AG AP. Now i should configure a Aironet 1130 Repater for this WLAN. The initial connection from the Repater with the AP is no Problem. But after some time the Repeater lost the connection.


On the AP i see following Messages:

Hello,


This usually indicates high inteferance around your aps.


Note: High error counters on radio interfaces on the client, the access point or bridge indicate the effects of RF interference. You can also identify RF interference through system messages in the logs of the access point (AP) or bridge. The output looks like this:


May 13 18:57:38.208 Information Interface Dot11Radio0, Deauthenticating Station 000e.3550.fa78 Reason: Previous authentication no longer valid
May 13 18:57:38.208 Warning Packet to client 000e.3550.fa78 reached max retries, removing the client

This could be due to rf interfirence, bad antenna alingment, that the bridges do not hava clear line of sight between them or clear fresnel zone.
