It seems Mango does not have sufficient storage to install LuCI. You can try configuring manually in SSH, at your own risk and without any guarantee:
-
Connect and log into router using SSH
-
Enter the command to detect the USB drive:
block detect
Check for an UUID should be displayed with format like “XXXX-YYYY” and record the UUID.
- Enter the command to add the mount point:
echo "
config mount
option uuid ‘XXXX-YYYY’
option target ‘/mnt/USB’
option enabled ‘1’
option options ‘rw’
" >>/etc/config/fstab
where XXXX-YYYY is the recorded UUID (keep the single quotes)
- Enter the command to mount the USB drive:
block mount
- Enter the command to display the mount points:
mount
There should be an entry for /mnt/USB if the USB drive has been mounted and proceed to the next step. If not, then stop now because the mount did not work.
- Go to the standard GL GUI and under APPLICATIONS, click on File Sharing. Turn ON Share via Lan, turn OFF Share via WAN, turn ON Writeable. Pick /mnt/USB in the Current Directory box and click on Apply.
If everything worked, then you will be able to access the shared USB drive.
