Sharing via SAMBA problems-Spanish

The AR750S has NAND and NOR flash. With the plain vanilla OpenWrt image you can only use the latter flash type - initially only flashable via web based uboot. For details see here: https://blog.gl-inet.com/how-to-enter-the-uboot-web-ui/

thanks

since i was not able to flash the last available open wrt image, i set the router back to factory settings
and now for some reason i can start samba.
the gl-ar750s is a travel router, so i have it connected like a repeater of my home router.

However i still have two (new) issues:

  1. when the windows laptop gets internet access through the router: In this case i can access the usb drive connected to the router, it shows up in windows file explorer/network , however once i enter in the usb drive it doesnt show any file.

  2. when the windows laptop gets internet access through the home router (to which the travel router is also attached) : In this case the router still shows up in windows file explorer network, but i can not access it
    It seems to me that in the latter case something should be done with the router firewall but i am not sure what.
    I found this , do you think this is what is needed? and if so how can i configure the routers firewall.
    Excuse my ignorance

    Configure /etc/config/firewall to open the following ports (if your LAN access is rejected by default):
    TCP 137 - NetBIOS Name Service
    TCP 138 - NETBIOS Datagram Service
    TCP 139 - NETBIOS Session Service
    TCP 445 - Microsoft Directory Services

config 'rule'
option 'src' 'lan'
option 'proto' 'udp'
option 'dest_port' '137-138'
option 'target' 'ACCEPT'

config 'rule'
option 'src' 'lan'
option 'proto' 'tcp'
option 'dest_port' '139'
option 'target' 'ACCEPT'

config 'rule'
option 'src' 'lan'
option 'proto' 'tcp'
option 'dest_port' '445'
option 'target' 'ACCEPT'

Somehow I have sorted everything out
But now I don’t know how to create a smb user
I don’t want to configure files
Can it be done from within luci?

This the template
I have added here two users, but to no avail, I can’t give them a password with smbpasswd in terminal because it doesn’t recognize the users kuku and luisa

This is my template smb config from luci

[global]
	netbios name = |NAME| 
	display charset = |CHARSET|
	interfaces = |INTERFACES|
	server string = |DESCRIPTION|
	unix charset = |CHARSET|
	workgroup = |WORKGROUP|
	browseable = yes
	deadtime = 30
	domain master = yes
	encrypt passwords = true
	enable core files = no
	guest account = nobody
	guest ok = yes
	invalid users = root
	local master = yes
	load printers = no
	map to guest = Bad User
	max protocol = SMB2
	min receivefile size = 16384
        null passwords = yes
	obey pam restrictions = yes
	os level = 20
	passdb backend = smbpasswd
	preferred master = yes
	printable = no
        valid users = kuku, luisa
security = share
	smb encrypt = disabled
	smb passwd file = /etc/samba/smbpasswd
	socket options = TCP_NODELAY IPTOS_LOWDELAY
	syslog = 2
        use sendfile = yes
	writeable = yes

I will start a new post since this last issue has nothing to do with the initial one from this post
