Delivering great wireless performance, network security and coverage, the D-Link Wireless N 8-Port Router (DIR-632) is ideal for building a powerful network. Designed to do the heavy-lifting and get your small business humming, 8 ports let you connect just about anything you can imagine, all at once - printers, laptops, desktops, security cameras, servers, storage drives - you name it, the DIR 632 can handle it. It also serves as an excellent home router, since it's ideal for providing wired Internet connectivity for video, music, photos, and documents.

Pros of this hardware

  • Runs standard version of DD-WRT
  • Eight (8) wired ports
  • New Harware. 802.11n WiFi
  • Easy to install DD-WRT
  • USB Port
  • Great range, signal strength and stability

Cons of this hardware

  • The biggest knock about this router is it's frequent WIFI drops and lockups when using the stock firmware. Installing DD-WRT corrects this isssue.

Installation Instructions

Please note that is is pre-release firmware at the momment. Please read the support forum listed at the bottom of this page before loading it on you router to avoid bricking it.

Out-of-the-box factory firmware upgrade

To install dd-wrt on a stock D-Link DIR-632, you can flash it directly from the router's web admin page (yes, that is correct... from D-Link's standard web interface). These are the steps to follow:

  1. Download the current firmware: NA (North America), AP(Asia Pasific), or WW (Any place else in the world) Factory-to-ddwrt r18777.
  2. Connect to the DIR-632 using an Ethernet cable.
  3. Setup your PC with static IP on subnet, such as
  4. Hold down the Reset button until the power light starts flashing yellow (under 30 sec).
  5. Open in your web browser (Firefox recommended), which should open the DIR632's administrative page from the standard D-link firmware.
    1. The D-link's default login details are user "admin", password is blank.
    2. Tools -> Firmware
    3. Click "browse" button -> select the "factory-to-ddwrt_NA.bin" file -> click "Upload" button.
    4. Wait 2 or 3 minutes for the DIR-632 to flash and do the update. You will see a status page that shows you the progress as it happens. After the flash & update is done, the router will reboot to dd-wrt, and the IP address will have changed to There is no need to reset.
  6. Open in web browser. Will probably have to update your IP address (if using static IP) to this subnet to be able to connect. This should open DD-WRT's web interface. Configure DD-WRT as desired.
  7. You're finished! No need to 30/30/30 hard reset, but you can reboot your router after several minutes. (I don't know if it has to build anything in NVRAM, but better safe than sorry.)

How to upgrade with new DD-WRT firmware

  1. Download the latest firmware dir632a-firmware r18777.
  2. Open the DD-WRT's web interface in your web browser. It's by default.
  3. Administration tab -> "Firmware Upgrade" button
  4. Click "browse" button -> select the "dir632a-firmware.bin" file -> click "Upgrade" button. It will take about 2 minutes to upload and write the flash. Your browser will reload and let you know when it is done.
  5. It is probably a good idea to reboot after updating. That's it.

How to reset the Router to initial DD-WRT configuration

If you forget the username or password, or if the configuration becomes really messed up, you can always clear all the non-volitile parameters by doing a 'factory reset'. To do this, with the router already fully booted, press and hold the reset button for 5~6 seconds and release. The router will boot back up and answer to just as if it had just been flashed with DD-WRT.

How to restore to factory firmware

This has not been tested yet, but should work.

  1. Download the original firmware from the D-Link Support Site
  2. Set your computer's ip manually to: 192.168.0.X (not 1) AND set your subnet mask to
  3. Unplug the power cable to the router, and then press and hold the reset button.
  4. Plug in the power cable when the power led flashes orange release the reset button.
  5. Open in your web browser (Firefox recommended)
  6. Upload your original firmware and wait

USB Storage

What follows are the steps needs to use storage devices connected to the routers USB port.

  1. Connect the USB device to the Router.
  2. Restart the router.
  3. Open the DD-WRT's web interface in your web browser. It's by default.
  4. Services -> USB
    1. Enable Core USB Support
    2. Enable USB Storage Support
    3. Enable Automatic Drive Mount
    4. Select Save, and then Apply
    • You can ignore the Status: Not mounted message

FTP Access

Once set up, you will be able to access all the mounted partitions by using

  1. Serices -> NAS
  2. Enable ProFTPD
  3. Select other settings and then select Save, and then Apply

File Sharing Access

Once set up, you can access your files using Universal Naming Convention (UNC) names; ex. \\\part1. Storage devices can be format as Fat16, Fat32, NTFS, and Ext2. The Ext3 drive format is not support, and will not mount.

  1. Serices -> NAS
  2. Add Share
  3. Select the Share's Path, enter and name, and indicate is it's public or not. If it's pubic you do not have to add users.
  4. Repeat 2 and 3 for each share
  5. Select Save, and then Apply

  • If you plan to add user, do so after adding the shares.

USB Printing

What follows are the steps needs to use printer devices connected to the routers USB port.

  1. Connect the USB device to the Router.
  2. Restart the router.
  3. Open the DD-WRT's web interface in your web browser. It's by default.
  4. Services -> USB
    1. Enable Core USB Support
    2. Enable USB Printer Support
    3. Select Save, and then Apply

Using the printer in Windows 7

  • Open Control Panel, Devices and Printers
  • Choose Add a printer, and then Add a Local Printer
  • select Create a new port, and choose Type of port: Standard TCP/IP Port. Click Next
  • Enter the IP address or your router: If you like you can give the port a name.
  • UNCHECK the checkbox to Query the printer and automatically select a driver use. Click Next. Now wait until the detection is done. It will say that the device is not found. Don't despair
  • Choose Custom and then click Settings
    • Make sure that Protocol Raw is selected and Port 9100 is entered. That will be proposed.
    • Leave all other settings also as they were and click OK
  • Click Next.

  • Give your printer a name, , then click Next
  • You don't have to share the printer. click Next
  • You can set it as default printer if your would like.

Don't forget that your routers default address is and its port is 9100

Common Problems

  • Wireless Security WPA2 does not work with i Touches. Use WPA instead with AES or TKIP+AES encryption.
  • When mounting USB devices, an odd message is produced indicating Status: Not mounted. This can be ignored.
  • Can only load on the NA (North American) versions of the router. A trouble ticket has been created. For AP (Asia Pacific) countries and WW (Europe etc.) instructions are available in the forum on how to create a firmware version that will load on your router.
