Yes, here we are: on "USB application" section, in SAMBA WebUI settings, if you try to set "Allow guest access" the related settings on smb.conf seems not affected. Indeed I checked and the following 2 commands have been set differently than my last backup of smb.conf file on jffs:
Code:security = USER guest ok = no
In order to allow the acces from guest they are supposed to be:
Code:security = SHARE guest ok = yes
Could you check if this starnge behaviour is reproducible from you also? In this case I did a fresh install of 380.59 by resetting all the NVRAM/jffs parameters
Works properly for me. Make sure you're not overriding it with a /jffs/configs/smb.conf file. Also don't forget to apply the settings after enabling Guest mode.
