Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to
access the network and connect to other devices as needed. UPnP devices can automatically
discover the services from other registered UPnP devices on the network.
To turn on Universal Plug and Play:
1.
From the main menu, under Advanced, click
UPnP
. The UPnP screen displays.
2.
The available settings and information in this screen are:
Turn UPnP On
.
UPnP can be enabled or disabled for automatic device configuration.
The default setting for UPnP is disabled. If this check box is not selected, the router does
not allow any device to automatically control the resources, such as port forwarding
(mapping) of the router.
Advertisement Period
.
The advertisement period is how often the router broadcasts its
UPnP information. This value can range from 1 to 1440 minutes. The default period is 30
minutes. Shorter durations ensure that control points have current device status at the
expense of additional network traffic. Longer durations might compromise the freshness
of the device status but can significantly reduce network traffic.
Note:
If you use applications such as multiplayer gaming, peer-to-peer connections, real-
time communications such as instant messaging, or remote assistance (a feature in
Windows XP), you should enable UPnP.

Advertisement Time To Live
.
The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. The time to live hop count is the number of steps a
broadcast packet is allowed to propagate for each UPnP advertisement before it
disappears. The number of hops can range from 1 to 255. The default value for the
advertisement time to live is 4 hops, which should be fine for most home networks. If you
notice that some devices are not being updated or reached correctly, then it might be
necessary to increase this value.
UPnP Portmap Table
.
The UPnP Portmap Table displays the IP address of each UPnP
device that is currently accessing the router and which ports (Internal and External) that
device has opened. The UPnP Portmap Table also displays what type of port is open and
whether that port is still active for each IP address.

Chapter 7
USB Storage
This chapter describes how to access and configure a USB storage drive attached to your router.
This chapter includes the following sections:
“USB Drive Requirements
“File Sharing Scenarios” on page 7-2
“ReadyShare Access” on page 7-10
“USB Storage Basic Settings” on page 7-4
“Configuring USB Storage Advanced Settings” on page 7-7
“Unmounting a USB Drive” on page 7-10
“Specifying Approved USB Devices” on page 7-11
“Connecting to the USB Drive from a Remote Computer” on page 7-12
“Connecting to the USB Drive with Microsoft Network Settings” on page 7-12
USB Drive Requirements
The router works with 1.0 and 1.1 (USB Full Speed) and 2.0 (USB High Speed) standards. The
approximate USB bus speeds are shown below.
Note:
The USB port on the router can be used only to connect USB storage devices like
flash drives or hard drives. Do not connect computers, USB modems, printers, CD
drives, or DVD drives to the router USB port.

Actual bus speeds can vary, depending on the CPU speed, memory, speed of the network, and
other variables.
The router should work with most USB-compliant external flash and hard drives. For the most up-
to-date list of USB drives supported by the router, go to:
/a_id/11280
.
The router supports both READ and WRITE for FAT16, FAT32, NTFS, and Linux file systems
(EXT2 and EXT3).
File Sharing Scenarios
You can share files on the USB drive for a wide variety of business and recreational purposes. The
files can be any PC, Mac, or Linux file type including text files, Word, PowerPoint, Excel, MP3.
pictures, and multimedia. USB drive applications include:
Sharing multimedia with friends and family—sharing MP3 files, pictures, and other
multimedia with local and remote users.
Sharing resources on your network—storing files in a central location so that you do not have
to power up a computer to perform local sharing. In addition, you can share files between
Macintosh, Linux, and PC computers by using the USB drive as a go-between across the
systems.
Sharing files with offsite coworkers—sharing files such as Word documents, PowerPoint
presentations, and text files with remote users.
A few common uses are described in the following sections.
Sharing Photos with Friends and Family
You can create your own central storage location for photos and multimedia. This eliminates the
need to log in to (and pay for) an external photo sharing site.
To share files with your friends and family:
1.
Insert your USB drive into the USB port on the router either directly or with a USB cable.
Note:
Some USB external hard drives and flash drives require drivers to be loaded in to
the PC before the PC can access the USB device. Such USB devices will not work
with the WNDR3700 router.

Computers on your local area network (LAN) can automatically access this USB drive using a
Web browser or Microsoft Networking.
2.
If you want to specify read only access, or to allow access from the Internet, see
“Configuring
USB Storage Advanced Settings” on page 7-7
.
Storing Files in a Central Location for Printing
This scenario is for a family that has one high quality color printer directly attached to a PC, but
not shared on the local area network (LAN). This family does not have a print server:
The daughter has some photos on her Macintosh computer that she wants to print.
The mother has a photo-capable color printer directly attached to her PC, but not shared on the
network.
The mother and daughter’s computers are not visible to each other on the network.
How can the daughter print her photos on the color printer attached to her mother’s PC? This is
where the USB drive on the router can save you time and effort.
1.
The daughter accesses the USB drive by typing
\\readyshare
in the address field of her Web
browser. Then she copies the photos to the USB drive.
2.
The mother uses her Web browser or Microsoft Networking to transfer the files from the USB
drive to the PC. Then she prints the files.
Sharing Large Files with Colleagues
Sending files that are larger than 5 MB can pose a problem for many e-mail systems. The router
allows you to share very large files such as PowerPoint presentations or ZIP files with colleagues
at another site. Rather than filling up their mail systems with large files, your colleagues can use
FTP to easily download shared files from the router.
Sharing files with a remote colleague involves the following considerations:
There are two user accounts: admin and guest.
On the FTP site, your colleagues should use the guest user account and enter any password
(FTP requires that you type something in the password field).
Note:
The password for admin is the same one that you use to access the router. By
default, it is
password
. The guest user account has no password.
