Hi,
If you want that the bridge and client can associate they have be using the same channel.
The bridge has be configured: Root w/clients, and they have be configured with the same SSID.
Verify the bridge and clients configurations If something setting changed when you did the change then adjust
If this don´t work then resett the configuration.
See chapter 10. Managing Firmware andConfigurations.
Section: Downloading, Uploading, and Resetting the Configuration.
good luck,
Norma
