Hi,

i have updated the er605 in my omada-installation to firmware 2.1.1

For one day it looks like everything is working, so i decide to update my other installations (4) also. Bad decission - today my son told me he is unable to connect to the wifi network with his phone. I checked my wifi-connections (different ssid / vlan) and that works. So i looked into the controller and find connected clients without ip-address and connected clients with wrong ip-addresses (from the wrong vlan!)

I see no way how to fix it. I´ve already rebooted the controller, the router, the ap´s - nothing change. I can´t go back to v2.0.1 - because with this firmware i had massive adoption-problems (constant rolling between connected - configuring).

Has anyone a idea? 

Thanks!

Update: Tried a downgrade to 2.0.1 in my local network. Maybe it works. It tooks about 20 Minutes. When i was able to login i see the Router in state "configuring" and shortly after that "disconnected". 5 minutes later it looks like the router reached the "connected"-state. So far the downgrade may works, but some wifi clients are still without a ip / with a wrong ip...
