Product summary 

 DIR-825

The good: Virtual networked USB port; mobile router capability; true dual-band; intuitive and responsive browser interface; gigabit LAN and WAN; easy to set up; support separate wireless networks for guests; convenient preset settings.

The bad: Slow mixed mode performance; range could be better; bulky design.

 

 Setup and design

 
We didn’t experience any problems setting up the D-Link DIR-825. The router comes with a CD that contains the D-Link Router Quick Setup desktop software. Dutifully following the wizard, we were able, with minimal mouse clicks, to get everything up and running, including connecting to the Internet and other wireless clients, as well as setting up an SSID for each frequency. Alternatively, you can use the Web-based interface, which we found to be well-thought-out, responsive, and more comprehensive than the desktop application.

The D-Link DIR-825 looks just like the DIR-655, minus the third antenna. The two antennae, however, are still attached to the back of the router where all the ports reside. This is a cluttering and long-standing design trait found in all D-Link’s Wireless-N routers. Nonetheless, with the omission of the middle antenna, it’s much easier to get to the DIR-825’s ports than the DIR-655’s.

Features

 
Despite similarities in appearance, the DIR-825 is much more advanced than the DIR-655. It’s the second router from D-Link that supports true Wireless-N dual-band, capable of broadcasting simultaneously in 5GHz and 2.4GHz frequencies. (The first was the DIR-855, which we reviewed earlier this year). The DIR-825 is the first, however, to feature the SharePort technology that allows the router’s USB port to work as a networked USB port. SharePort comes with a software application called SharePort Network USB that you’ll need to install on your networked computers. The software lets the computer recognize a USB device plugged into the router as if it were plugged directly into the computer’s USB port. Unlike other USB-equipped routers that support only printers and external hard drives, SharePort lets the DIR-825 share virtually any USB device over your network.

We tried the Seagate FreeAgent Xtreme external hard drive with the DIR-825’s USB port and the moment we plugged it in, the SNU utility in all the computers in the network prompted that a new device has been plugged in and asked if it should connect to it. Once we selected the computer and connected to the drive, the utility on other computers showed that the hard drive had been taken and gave an option to message the host computer to release it, which would happen if the user at the host computer agreed. We were also able to share that hard drive (as though it was connected to the computer directly) and made it available for the rest of the network to access at the same time, the same way you would share a folder on that computer. This seems to be a workaround for the above-mentioned weakness.

 

User Reviews

 

RollinAlong said: Researched several different options for wireless networking prior to purchasing this model. I’m not overly techinical when it comes to home networking, but know enough to get myself in trouble and thankfully the ease of the router setup didn’t allow me to get in trouble. No issues with dropping the network.

jack5578 said:Dual band, great User Interface, lots of bells and whistles, lots of functionality. This router has all the functionality of a more expensive “gaming router” at a much better price.

This router is a great value for the price. It has all the current bells and whistles. 2.4 and 5.0 Mhz, simultaneous dual band, gigabyte ethernet ports, USB port to plug in any USB device to share. The user interface is really nice and has a lot of features to set your router up any way you want. This router has all the features of the more expensive “gaming routers”. I’m using this router for everything; web surfing, gaming, voip phone, video streaming, media server with PS3, and file and print sharing. This router doesn’t miss a beat. I have experienced no shuttering or slowdowns. Video streaming is smooth and steady, and voip calls are as clear as a landline.

If you buy this router, download the latest firmware for the router on the dlink website. I struggled for two days trying to get the shared printer to work. But once I downloaded the latest firmware it worked immediately. There is a little button in the user interface that says “check for latest firmware version” or something like that. When you click it, it says you already have the latest version. That was the first thing I checked when I had problems with the printer. Two days of struggle later, I went to the dlink website and saw there was a much newer version of the firmware. So, don’t believe the little status button in the user interface, go to the dlink website and look for yourself, download and update to the latest firmware.

brandnewjesus said:I love the ease of setting reservation list, prioritizing traffic, and port forwarding to have one person watching hulu and ps3 online, and bit torrent running without and lag across the house through 3 walls, 1 insulated.

The share port utility is pretty useful if you just need to grab something off your drive real quick, but if your planning on using it to back up you downloaded movies its a little slow.

WEP

WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. Enabling WEP allows you to increase security by encrypting data being transferred over your wireless network.

When WEP encryption is enabled, there are up to four options*: 64-bit and 128-bit. 64-bit is the same as 40-bit WEP. The lower level of WEP encryption uses a 40-bit (10 character) “secret key” (set by the user), and a 24-bit “initialization vector” (not under user control). So lower level 40 and 64 bit WEP cards are equivalent in encryption strength and compatibility.

* 802.11B supports 64 and 128-bit encryption, 802.11B+ (enhanced) supports 64, 128, and 256-bit encryption, 802.11G support 64 and 128-bit, and 802.11A supports 64, 128, and 152-bit encryption.

WPA

WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy). The technology is designed to work with existing Wi-Fi products that have been enabled with WEP (i.e., as a software/firmware upgrade to existing hardware).

To allow traffic from the internet to enter your local network, you will need to open up ports or the router will block the request.

Because our routers use NAT (Network Address Translation), you can only open a specific port or ports to one computer at a time. For example: If you have 2 web servers on your network, you cannot open port 80 to both computers. You will need to configure 1 of the web servers to use port 81. Now you can open port 80 to the first computer and then open port 81 to the other computer.

For the DI-514, DI-524, DI-604, DI-614+, DI-624, DI-704P (revC), DI-704UP, DI-754, DI-764, DI-774, and DI-784:

Step 1: Open your web browser and enter the IP address of your D-Link router (192.168.0.1). Enter username (admin) and your password (blank by default).

Step 2: Click on the Advanced tab at the top and then click Virtual Server on the left side.

Step 3: Check Enabled to activate entry.

Step 4: Enter a name for your virtual server entry.

Step 5: Next to Private IP, enter the IP address of the computer on your local network that you want to allow the incoming service to.

Step 7: Enter the port information next to Private Port and Public Port. The private and public ports are usually the same. The public port is the port seen from the WAN side, and the private port is the port being used by the application on the computer within your local network.

Step 8: Enter the Schedule information.

Step 9: Click Apply and then click Continue.

For DI-704P (rev.B), DI-707P, DI-714P+, DI-804HV, DI-808HV, and DI-824VUP users:

Step 1: Open a web browser and enter the IP address of your router (192.168.0.1). Enter admin for your username and then your password (blank by default).

Step 2: Click on the Advanced tab and then Virtual Server on the left side.

Step 3: Enter the following information:

Check the box next to Enable.
Next to Service Ports, enter the port or range of ports you want to open.
Next to Service IP, enter the IP address of the computer you want to open the port to.
Click Always next to Schedule or enter the time frame that you want.

Step 4: Click Apply and then click Restart to save your changes.

client mode

Client Mode allows the D-Link DWL-2100AP to become a wireless client to another AP or wireless router. Client mode allows any device with an Ethernet connection to connect to your wireless network, such as a printer, gaming console (Xbox, PS2), or a computer.

You will need the MAC address of the device you want to be a client to. If you are connecting to a wireless router, then you must use the LAN or Ethernet MAC address, not the wireless address.

Step 1: Connect the DWL-2100AP to your PC using an Ethernet cable. You cannot connect to the DWL-2100AP wirelessly when in client mode.

Step 2: Your computer will need to be in the same IP address range as the DWL-2100AP for configuration. The default IP address is 192.168.0.50.

Step 3: Open a web browser and enter in the IP address of the access point (192.168.0.50). The username is admin (all lower case) and the password is blank (nothing).

Step 4: Click on Advanced at the top and then click Mode on the left side. At the bottom, click the AP Client button. Enter the MAC address of the device you want to repeat (IE 50:23:AB:D4:56:E1).
