I have tried twice to upgrade the firmware on my R510.
It is currently running 18.104.22.168.253 and I want to upgrade to 22.214.171.124.195. I am performing an online upgrade.
It appears to flash properly but once the AP is rebooted it tells me to downgrade to 126.96.36.199.253 which I am able to do. It appears this is a known problem as I have found several mentions of it on various Google searches. Unfortunately there is not a known resolution I have found.
Any assistance would be most appreciated. Thank you.
