The TG582n router has a USB port towards the back of the left-hand side. There are 3 different uses for this:

plugging in a 3G mobile broadband dongle, which can add 3G connectivity
plugging in a USB storage device, which can allow content sharing server(s) to share its contents
plugging in a USB printer, which can allow a printer sharing server to share the printer

3G broadband

Content Sharing

The content sharing server uses a separate 'virtual' interface, which it grabs its IP via DHCP. It appears to use the first DHCP pool to obtain its address, it's possible to add an extra pool which just serves 10.0.0.137 (for example) for the content server.

View the IP which content sharing has on the web interface: - Home Network - Interfaces - Local Network:

Note here content sharing has taken the only available IP!

To view the list of interfaces:

:eth bridge list

To remove this interface, and therefore to stop it grabbing an IP:

:eth bridge ifdetach intf virt brname bridge
:eth bridge ifdelete intf virt brname bridge
:saveall

If one wishes to use content sharing, the available servers are:

CIFS server (aka SMB, Samba)
UPNP AV server
FTP server

The TG582n can use a USB storage device with a single partition formatted as FAT32. (Your author has not tried anything else yet)

CIFS server

The current config can be seen with

:contentsharing cifs list

If one enables the CIFS server with

:contentsharing cifs config state=enabled

then it's possible to connect to the CIFS server on the previously found IP address in any of the usual CIFS ways. Note that the CIFS server uses old LANMAN authentication - so Samba users may need to add something like:

 # Be able to connect to old servers (e.g. TG582n content sharing)
client lanman auth = yes
client ntlmv2 auth = no

to smb.conf. It's then possible to authenticate with a router username/password - at least, the Administrator account credentials work OK.

For example, with the content sharing server on 192.168.1.32:

$ smbclient -U Administrator //192.168.1.32/Disk_a1
Enter Administrator's password: 
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 2.2.12]
smb: \> dir

Printer Sharing

Your author doesn't have a printer with a USB connection, so can't offer much guidance. The command to enable printer sharing would be:

:printersharing LPD config state=enabled

And you'd need to add a queue, a good place to start is:

:printersharing LPD queue menu
