Unlocking the Telnet Cosole On Windows
Netgear provides a developer tool for unlocking the console access from a Windows client. Windows NT and later versions are assumed to work, administrator privileges are required. This was successfully tested on Windows XP SP2.
Here's the process:
- Download the file wpn824_ko_2.12_1.2.9.zip file from the korean NetGear support website (scroll down) or from the other locations I found it at (mirror 1, mirror 2) and unzip it. (20060701 this file is only still available on mirror 2) Mirror 3 (works, 01-MAY-2007)
- Login to Windows using an account which has administrative privileges (needed for sending custom crafted network packets which this tool does)
- You will see a M$ Word doc which contains screenshots and instructions in korean language, a firmware update (you don't need this) and the telnetEnable.exe tool
- Open a command line (windows console) window. To do so, press and hold windows key, then press R once and release both. In the new windows, type cmd, then press enter)
- Get the MAC address of your Netgear router. You can use either 'arp -a' and use the 'physical address' or look it up on the web interface of your router (Maintenance -> Router status -> LAN port -> MAC Address)
- Copy or type the MAC address to a text editor such as Notepad, Wordpad or Write
- Remove any minus signs (-) or colons (
, replace all characters by their upper case representation (a -> A, d-> D etc.) - Copy the result of your editing to the clipboard and return to the command line window
- type (without quotes) "telnetenable.exe ", the IP address of your router (e.g. "192.168.1.1"), add another space (" "), paste the contents of the clipboard, and append " Gearguy Geardog". These are the default username and password for telnet console access (they differ from those of the web interface), you need to modify them appropriately if you changed them previously. The result should look similar to this:
telnetEnable.exe 192.168.1.1 000FB5A2BE26 Gearguy Geardog
then get the firmware off the netgear website and flash via gui
be aware that the router wont accept the firmware update via gui using firefox
