DG834v1, DG834v2, DG834Gv1 and DG834Gv2 Router Recovery Utility
Published April 8, 2004
Use this utility when the router's Power and Check light blink alternatingly after firmware upgrade
using the usual Web-based method.
The utility requires a Windows PC (not
UNIX or a Macintosh). This utility is tested for Windows 2000 and Windows
XP. It may not work in other versions of Windows.
To Recover the Router Firmware and
Restore Normal Function
- You need one of the firmware update files in the "Downloads" section of your product's page.
- Select your router here. Download a version of firmware (the latest one is usually best), and unzip the file. You need the file inside that ends with ".img" to use in Step 6.
- Download the recovery utility using the button below to a convenient
place such as your desktop.
566KB
- Connect a single PC directly to the router using an Ethernet
connection. If you had to download with a different computer, move the
zip file to this PC connected directly to the router. Use this
PC for the remaining steps.
- Unzip the downloaded file, putting everything that's extracted in
the same directory.
- Move the ".img" firmware file that you download in preparation for
this process into the same directory as in Step 5.
- Double-click UpgradeWizard.exe. The Recovery Utility starts.
- Click Next. A screen with "Adapter Card Lists" appears.
- Select the adapter whose Ethernet connection goes to the DG834. Note:
Several cards may appear in the list — including ones that are no longer
installed on your computer, or are no longer used.
- Click Next.
- There should be one and only one item in the Device List. Click Next.
- Click Next.
- Click Upgrade. The utility recovers the router: EEPROM is erased,
firmware is upgraded, then functionality is verified. A message appears
that you are successful.
- Click Close to complete the recovery.
The router is fixed and can be used normally, now.
