I too earferly tested the new beta firmware controller, but it ended on me having to reset everything on the network and starting again from the scratch,

How's my setup?

- Single WAN, it has a fiber SFU ONU plugged into the SFP port of er7206 v1.0 working flawlessly since installation.

- The fiber ISP uses PPPoE for subscriber authentication

before upgrade:

- Everything was working, could configure the connection paramters, the correct vlan..etc

after upgrade

- Internet down, after visting the wan configuration section.. all the VLAN parameters either missing or (after device hard reset)

the "internet vlan" checkbox is greyed out (wth?)  I tried everything, removing configuration, starting over, hard reset of er7206, ended with downgrading controller, resetting everything on the network to get back on track.

It seems to be that the act of "adding a name" to the sfp connection, triggered a save new configuration event that screwed everything up.

I could of course untag the internet vlan on the stick and pretend I have a dumb consumer device but I do not wish to wake up the daemons of the sfp module's firmware which is let's say capricious and obscure.
