Netgear WiFi extender with OpenWRT guide.

To flash the extender you’ll need to setup a environment so to speak. You’ll need a temporary HTTPd server and a slew of files.
You also need to flash the extender with the WNR2000 firmware like in the last guide.

On your desktop create a folder called netgear.
Download the following and put the files into that newly created folder.

If you don’t have a HTTPd server you can get this super small open source one from here

Now unzip the file telnetEnable.exe. Open Notepad and type in the following.

telnetEnable.exe “MAC ADDRESS” Gearguy Geardog

The “MAC ADDRESS” needs to be changed to reflect on the extender. On the back of the unit near the reset button there should be
a white label that has a bar code and a number, You need the number. For for a example it would look like

telnetEnable 12E52A68F83C Gearguy Geardog

Save it as a BAT file by selecting “Save As” and label the file RUN.BAT then under “Save as type” select All files (*.*) and select save. Put it into the netgear folder.

At this time you can direct connect the extender to your PC. Change the network settings on the PC from DHCP to Static. Use these settings.

IP Address:
Subnet Mask:
Default Gateway:

Preferred DNS Server:

If you have wifi make sure its turned off. We’re using a cabled connection for this project.

Run the BAT file and also open HFS. Select the following files and drag and drop them into the HFS window.


Now lets connect to the extender via telnet. Select the start button and type in CMD, right click on it and select “Run as administrator”.
Type in telnet Now you should see a terminal session appear.

run the following commands.

cd /tmp

The files have just got transferred. Now for the scary part. Once again copy the commands. FYI we only get one shot at this. so don’t foul up.

mtd -e mtd0 write u-boot.bin mtd0
mtd -e mtd1 write ubootenv-stockpartitions.bin mtd1
mtd -e mtd2 write root.sqfs mtd2
mtd -e mtd4 write uImage mtd4

Wait for about ten or twenty minutes. The extender is flashing itself.
When the time has passed it should have a green light on the front panel.
Open your web browser and enter the address and OpenWRT should greet you. All is well and just follow the instructions to set it up.
