Most modern printers include Wi-Fi features of some kind, allowing for wireless printing tasks. However, what do you do if you have an older model that lacks these wireless features? You can always plug it directly into the USB port on your router and use it to print up copies of documents and the like. As an added bonus, that will be one less device wirelessly connected to the router, if you are wondering how to remove devices from a router.

Attach a Hard Drive as a Media Server

You can connect a USB hard drive to your router via the USB port to create a quick and easy media server. Any computer connected to your network will be able to download or stream any files stored on the hard drive. This is great for watching movies, the latest streaming TV shows, or even listening to music.

Attach a Hard Drive for Backing Up

You can also connect a USB hard drive for the purpose of backing up files, which is something we should all do more often.

Firmware Updates

One of the easiest ways to update the firmware software on your router is to download the file to a computer, transfer the file to a USB stick, and then plug the USB stick into your router via the USB port. In the amount of time it takes to microwave some eggs, you can have an up-to-date router operating system.


The port can also be used to charge certain devices, though your results may vary.

How to connect the router USB port or external storage device?

To connect a USB device, including a USB storage device, simply plug it into the USB port. This process may vary depending on your USB drive and the design of your Wi-Fi router.

Can I use the USB port on my router to have a wired connection to my Xbox?

You should be able to connect the Xbox via the USB port, but your bandwidth will be severely hampered. For better results, connect the gaming console via ethernet cable to an ethernet port. That will free up the USB port for an external drive.

How do I connect my router to my computer?

If you are having issues with a wireless connection, you may be able to use a USB cable to connect your computer to the router, for the purpose of accessing any diagnostic software.

STAT: You can set up authentication for your USB device so that network clients will be required to enter a username and password when accessing the USB disk. (source)

He now manages CNET San Francisco Labs, reviews 3D printers, networking/storage devices, and also writes about other topics from online security to new gadgets and how technology impacts the life of people around the world.

Editors’ note, December 14, 2015: This review was updated with its overall rating lowered to reflect its position compared with newer routers.

Asus RT-N56U Dual-Band Gigabit Wireless-N Router

The Good

The stylish and compact Asus RT-N56U Dual-Band Gigabit Wireless-N Router offers stellar 5GHz performance, long range, and an intuitive Web interface. Its storage feature is well designed; the router is comparatively fast; and it offers a convenient way to access data over the Internet.

The Bad

The Asus RT-N56U’s Web interface takes a long time to apply changes and the router doesn’t support the new three-stream 450Mbps wireless speed.

The Bottom Line

The compact and well-designed RT-N56U Dual-Band Gigabit Wireless-N Router is a major step up from its bulky and buggy predecessor, the RT-N16. It offers the fastest 5GHz speed to date and very good overall performance for both wireless and storage features.

The only two minor blemishes we find in the RT-56U are its Web interface, which, though intuitive and responsive, takes a long time to apply changes; and its lack of support for the new three-stream 450Mbps wireless standard, which competitor Cisco Linksys E4200 offers.

Shopping for a faster internet speed?

To make up for this, the Asus is much cheaper than the Cisco at around 130. If you’re looking for a well-rounded true dual-Band router that also offers decent built-in network storage features for your home, look no further than the Asus RT-56U.

Design and ease of use

The router is not designed to be wall-mountable but it comes with a detachable base to work in a vertical position. It can also be placed on its bottom, like all routers.

Despite the new compact physical size, the RT-56U packs a heavy punch. On the back, it has four Gigabit LAN ports (for wired devices) and one WAN port (to connect to an Internet source such as a broadband modem). Next to the ports, there are also two USB ports designed to host printers or network storage. This is the first router of this ultracompact size to come with two USB ports. Most compact routers we’ve reviewed don’t have a USB port at all. Between the USB ports and the LAN ports is a tiny reset button that restores the router to its default manufacturer settings.

On top, the router comes with an array of tiny blue lights labeled with the function each displays the status ofthe USB port, the wired network, the two wireless networks (2.4GHz and 5GHz), and the power.

It’s very easy to get the RT-56U up and running. First, plug the router in and turn it on. Next, from a computer that’s connected to the router via a network cable, open an Internet browser, such as Firefox. You will be greeted with a quick Web-based wizard that walks you through a few simple steps to set up the wireless networks and get connected to the Internet. In our case, this took less than three minutes. The setup is foolproof and probably the fastest way to set up a router we’ve seen.- possibly even faster than the case of Cisco’s E and Vale series, which are extremely easy.

After the wizard, you can use the router right away or stay in its Web interface to further customize its features. Later on you can log in to this interface again at any time by pointing a browser of a connected computer to its IP address, which by default is


The RT-56U’s Web interface is very similar to that of the RT-N16 but is much improved in terms of performance and utility. The new router also has more features. The only nag we had is the fact that the interface takes a long time to apply changes. It displays a countdown message that goes from 1 to 100 percent at a rate of about 2 or 3 percent per second, meaning almost every change takes close to a minute.

The interface has a nifty network map that show a schematic of all the devices connected to its network and USB ports. It also has a very easy-to-use quality of service (QoS) feature called EzQoS that lets you quickly prioritize what type of servicesgaming, media streaming, VoIP or Internet applicationsthat you want the network to prioritize for each connected device. There’s even a comprehensive Traffic Meter that shows the use of the Internet as well as wired and wireless networks in real time or in the past 24 hours.

The router’s USB ports support external hard drives formatted in either FAT32 or NTFS, and its storage feature works very well. In our trial, the router could handle two bus-powered external hard drives, the Seagate GoFlex Pro and the Western Digital My Passport. at the same time. So without needing too many wires running around, the router can offer up to 3TB of network storage (with two 1.5Tb external hard drives attached, such as the Seagate GoFlex Ultra-portable)not too shabby a number for a device of its size.

Once the hard drive is connected, you can choose to share its entire existing contents as public (simple share), meaning everyone can have full access to it; or you can choose to share it with accounts. Choosing the latter option lets you create multiple user accounts and assign access privileges, (read only, read/write, no access) for each account to each of the share folders. We tried all these different settings, via a section called USB Application within the router‘s interface, and they worked as intended.

There’s no need to install software on any of the network computer to access the router’s storage. You can just browse for it using a network browser, such as Windows Explorer, the same way you would to access another computer in the network. On a Mac, the router will appear automatically in the Finder. The RT-56U also supports media streaming and can stream digital content stored on the external hard drive to UPnP-compliant network media streamers.

What we liked the most about the RT-N56U is its DiskAid feature that allows for quick access to the router over the Internet, using Asus’ free Dynamic DNS. Normally, to use a DDNS service, you have to create an account and associate it with a router.- a pretty hard job for the uninitiated. In the case of the RT-56U, however, all you have to do is pick a unique name and then after three mouse clicks the service is up and running. After that you can remotely access the router via the Web address, where xyz is the unique name. For example, you can access the router’s storage at Or, to access the router‘s Web interface via the Internet, you can turn this feature on and then point a browser from a remote computer to

The router’s Web interface also comes with a very handy context-based help feature: each time you click on a setting to change something, a small part on the right of the interface will automatically display the detailed information of that setting. This makes using the router a really pleasant experience.

Other than the above, the router also supports all the standard features and security measures found in other routers. These include, but are not limited to, DHCP server, port forwarding, virtual server, all variations of wireless encryption methods, and so on.


We were very happy with the router’s performance both for its wireless networks and its built-in storage feature.

For the 5GHz Band, in a throughput test where the router was set up to be 15 feet from the client, it scored 112.6Mbps. At this speed, it can blast through 500MB of data in just around 30 seconds, which is the fastest we’ve seen for a wireless router. When we increased the range to 100 feet, the router still scored 76.1Mbps, which is the second best score on that test, just a tad slower than the 79.1Mbps of the Linksys E4200.

The RT-56U didn’t do as impressively on the 2.4GHz Band, but still managed to stay among the top three routers we’ve reviewed. In the throughput test, it scored 57.2Mbps and in the range test it offered 34.4Mbs. Finally, in the mixed-mode test where it was set to work with both N and legacy wireless clients, the router scored 52.6Mbps, which is a very good number.

The router offers a very good range with both bands: around 280 feet in our testing environment. It also passed our 48-hour stress test for both bands. During that time it didn’t disconnect once.

We didn’t have high expectations for the RT-56U’s storage performance, but it surprised us by being the fastest of all reviewed routers that have USB ports. The router scored 95.4Mbps for writing and 104.2Mbps for reading. While these numbers, as expected, are much lower than those of a dedicated NAS server, they are fast enough for casual backing up, data sharing, and media streaming.

Despite its tiny size, the RT-56U has good ventilation and therefore managed to stay cool and quiet even during heavy operation. It went though our testing without any problem at all.

What Is the USB Port on a Router For?

Look on the back of your router and you’ll probably see a USB port. A router will typically connect to a modem over Ethernet to provide it with a connection to the Internet, so what is the USB port for?

The USB port on the back of a router allows for different peripherals to be connected. The most common use cases are connecting a printer or external storage device so they are accessible to multiple devices over a wireless connection.

asus, router, modem, 4g-n12, wireless-n300

In this article, we’ll look at some of the different ways you can make use of the USB port found on the back of your router rather than letting it go to waste.

Connecting a Printer

It is possible to connect a printer to the USB port on a router.

This isn’t used as commonly these days due to the more modern printers having the ability to connect to your home network wirelessly, giving more flexibility as to where it can be placed in relation to the router.

That being said, some of the older printers can only be used via a USB connection.

To save everyone in the home having to physically connect their device in order to print, or having to purchase multiple printers, the printer could instead be connected to the router, with it essentially becoming a print server.

This will not only save on the cost of the printer itself as the latest printers that come with more features, such as wireless printing, are typically more expensive, but it just makes printing a much less painful task for everyone in the household.

Low Power Charging

It won’t be capable of charging high-end devices that require a large power input, however, the USB port on a router can be used to charge your phone, for example.

asus, router, modem, 4g-n12, wireless-n300

This can be useful when you don’t necessarily want to have to plug your charger into a wall outlet, or as a precautionary measure to prevent overcharging the device.

Cellular Connections

Connecting a cellular-based USB modem to the router allows you to share a mobile Internet connection with your entire home network.

In my opinion, this isn’t a hugely useful case for the USB port given how reliable broadband Internet services are these days, however, could be handy if you really cannot live without an Internet connection.

Should your broadband service go down for whatever reason, be it a cable fault or a problem with the service itself, the cellular connection provided by the USB dongle can be a great backup solution.

It’s worth noting that not all routers will support this feature, and even those that do will only support certain cellular modems, so be sure to check your router’s manual or with the manufacturer if this is a feature you would like to make use of.

Administration and Updates

The USB port on a router can be a useful way to update its firmware, configuration or any other information stored internally.

Updates can be downloaded from the manufacturer’s website, temporarily stored on a USB storage device which is then plugged into the router, and then installed.

Most routers will make sure their latest firmware and updates get installed without the need for you to do anything, but it’s nice to know the USB port is there as a backup.

Can You Plug a USB Hub Into a Router?

Perhaps you wish to take advantage of more than one of the uses I have described above, but there is only a single USB port on your router. So, can you plug a USB hub into the router, turning one USB port into many?

Theoretically, it is possible, however, probably isn’t recommended as the USB port built into a router typically is not the best quality.

Really, it is a nice little bonus and isn’t actually needed for the router to function as it was intended, so manufacturers are unlikely to invest much into a port than many people won’t even use.

I have heard stories of the USB port failing completely when USB hubs were plugged in, so my recommendation would be to stay on the safe side and not plug in a USB hub.

Keep the USB port set aside for whichever use case that we described above that you feel will be most beneficial to you.


The USB port on a router essentially allows you to share a particular device over your network, making it accessible to multiple users or devices at the same time.

The most common, and probably the most useful, uses are for the sharing of an external storage device or an older printer that cannot be connected to the network wirelessly.

Other uses include the ability to charge certain devices that require little power input, an alternative way of being able to install firmware and updates, and the being a backup cellular connection should your primary broadband link go down.

Regardless of what you plan on using the USB port on your router for, I would recommend first checking the manual to ensure it is compatible that that plugging in a non-supported device will not affect the router.
