That is a BUG Please open x terminal and enter this command to get your wlan ip. /sbin/ifconfig wlan0 | grep inet The output is something like this: inet addr: 192.168.178.100 Bcast 192.168.178.255 Mask: 255.255.255.0 Push the Config Button in TinySmbGui and enter the IP address and the Subnetmask which was displayed by the command and save the settings. Now try again to start the server. If the Server-Status is online. The Server running and the config is correct. You can ignore the Wlan-off message.
