I've attached an external HD to the USB port on my Ultra Hub and turned on Samba.
I can access it using //192.168.1./Seagate_Expansion_1_521a in my browser, which means I can see what's there and download stuff, but how can I upload? Do I need to use ftp?
Or can I access it from Windows File Explorer? If so, how?
With the old Huawei modem, it appeared as a network drive called ATP if I recall....
You can use File Explorer.
I've done it successfully on Win10 as per:
Note: If it can't connect to the share, your PC may not be configured as a Samba Client - see my response at:
In Windows 10 need to enable "SMB 1.0/CIF File Sharing Support" in "Windows Features", its off by default.
Just check the box for it in "Turn Windows features on or off" and restart
Now you will be able to see your attached USB drive via SAMBA in the file explorer
Caution: SMB 1.0 has has been identified as insecure as in thread http://community.vodafone.co.nz/t5/Modems-Wi-Fi/Vodafone-Ultra-Hub-USB-file-hosting-not-working/m-p/...
Vodafone really should address this e.g, through firmware update of the UltaHub to be compatible with SMB 3.
