WAC510 Firmware Update Failed

[jtison]

I've got firmware V 9.5.3.2, trying to update to 9.5.5.4 ... and I receive a return message after a couple of minutes saying "Firmware update failed". The LAN broadcast LED won't light up at all, by the way, which took me to Insight to update. Any experience anyone had with that? Thanks in advance (and sorry if this is a dupe)

have you tried updating through insight? 

Are you hardwired in for the update? 
Have you tried a different browser? or device?

Is this in WAC510 in router or AP mode?
