Hack Netgear WG602 access point to run dd-wrt

The basic system of Netgear WG602 is dumb, so get DD-WRT on top of it.

We have two Access Points, both Netgear WG602EE v4. According a review about the device, it has a limitation of 20 simultaneous sessions, so I started to look some kind of limit breaking. (Yes, we did have problems like this.)

Fortunately, these devices are on the list of the ones able to run dd-wrt. But how to hack?

The steps:

  • download the version for netgear from the dd-wrt page1
  • install tftp ( I use ubuntu, so apt-get install tftp)
  • add an IP address from 192.168.0.1/24 to your existing addresses, and one from 192.168.1.1/24 The first is because the access point’s default is 192.168.0.227, the second is because dd-wrt default is 192.168.1.1. This is always the default.
  • Login with the tftp session and enter the following: (the best is to enter these at the location, where you downloaded the dd-wrt binary)
tftp 192.168.0.227
verbose
trace
put dd-wrt.v24_micro_generic.bin image.idts334

Do not press enter at the end of the last line, just put is there!

The tftp only send/recieve data when put or get is entered, so you can log in without the other IP even exists.

  • On the device, press the reset button and hold for at least 10 seconds, than pull the power cord. Insert the power cord back while still holding the reset button and hold it for 5 seconds more.
  • 1 second after press enter at the tftp session. Attention! At this point, there’s no return, because no original firmware is available from Netgear.
  • You sould see a lot of send/recieve messages.
  • If the transmission was correct, you should be able to login to dd-wrt at the address 192.168.1.12
