Question:
After upgrading to firmware version 5.41, WLAN clients in the guest network were unable to obtain an IP address, even after resetting the configuration and reconfiguring the SSIDs.

Answer:
The issue was identified as a bug in firmware 5.41. The bug will be fixed in the next official release 5.42.

Before 5.42 is released, you can upgrade the device to the latest version "5.41WK46".
