Lol, I noticed that Bitdefender Internet Security kept popping up alerts that it was blocking suspicious activity. Probably catching your config file being pushed through. That explains it I guess. You might need to configure the routers while they're in your hands then, rather than trying to do it OTA if it's going to get blocked as suspicious. This is why we can't have nice things.
We actually opt for this as we are trying to make thing more convenient for clients like changing wifi password and resetting pppoe via the app or clientzone and it gets applied to the router automatically. Some decent features we think clients will enjoy. It's not perfect yet but definitely will get better.
