My AP1131Gs was automomous and I was upgrade to LAPs.After few days several APs was fail due to ethernet cable(one of pins is broken).I can not bring it up
connect to WLC anymore.Then I try to recover back to automomous by press Mode switch on APs through TFTP.It is back to IOS image but I found the APs FE0 and BVI1 always down.I try to change configure FE0 to speed 100/duplex full and it is up( link up/ping OK). But I can not upgrade this APs as before.
I was told this is AP bug?Is is true?
Someone could give me further info about this?
