I simply upgraded to this new firmware from the previous version without clearing nor reloading any configurations. It has been working just fine since I've loaded it. I don't use all the fancy QOS or anything though. Just using it for basic router connectivity. I do have all the AIProtection choices enabled. No hiccups or connection issues so far since I've loaded this new firmware. Also, I simply just loaded it and did not even power off and power on the router. I just let it update and reboot itself and been off and running since yesterday without any connection issues.
Oh, Oh! I just looked at the syslog this evening and see a ton of repeating messages occurring continuously at intervals. Here is a cut and pasted sample of what I am seeing: (What's up with that? I did not have any of that nonsense on the previous firmware!):
