That Channel.C error message might be cosmetic.  What is the error number?

 

It looks like your users cannot get on because your AAA server is not responding.

That "interference" is just foreign access points that the system can see.  It does not mean there is severe interference.

This is all I see for ID.  You should not have 40mhz channels for the AP225..

 

(Aruba7640-US) #show ap allowed-channels country-code ID ap-type AP-225

Allowed Channels for AP Type AP-225 Country Code "ID" Country "Indonesia"

[ Edited ]

Thanks a lot Colin. This will certainly help.

 

This error "An internal system error has occurred at file channel.c function ch_check line" does not seem to affecting the WiFi network.

 

Thanks again Colin for a quick response and I will check for 40MHz channel on AP225 for ID country code and will let you know.
