Note sure about that error message, but if the 430 SMs were on 11.2, did you update them to 12.1 first?

I keep getting this error: org.apache.commons.net.io.CopyStreamException: IOException caught while copying. (SITE= No Site Name) I have disabled firewalls, tried using HTTPS, using latest CNUT… everything… at my wits end. We had a 430 AP died, putting up a 450… need to get the 430 SM to compatibility mode. Help? Cheers, Andreas Wiatowski, CEO Silo Wireless Inc. 1-866-727-4138 x-600 Web: www.silowireless.com Facebook: www.facebook.com/silowireless Twitter: @silowireless
