Recently I updated my Deco's to latest firmware version and almost all my 2.4 devices lost connectivity to internet. The devices are able co connect to the network, and all the network settings are fine but the device cannot reach internet. Not sure if I have to change a configuration but right now I already do a factory reset to a TV Samsung 65" and a Xbox 360.

Already tried to disable an re-enable the fast rooming option, reinstallation of the firmware. Don't want to do a rollback, as maybe the configurations that I have cannot be restored form the backup, but only want to make sure that it's my only option.
