  • Page 3: Flash Preparation

    Research model and build threads before blindly flashing any dd-wrt build Read "the Peacock Announcement" For first time installs over the Netgear firmware, a "trailed" *.chk file (with the router name) is required. Initial flashing: use this trailed build from here. Note that eko builds are gone.

  • Page 4: Upgrading With Dd-Wrt

    Perform the update and allow sufficient time to complete ♦ Although the router has 4MB flash, the Netgear partitioning and CFE limits the available partition size to 3735552 bytes (3648 KB) for linux and rootfs combined. See the Peacock Announcement for details.

    Ping 192.168.1.1: a TTL=100 indicates TFTP recovery mode TFTP an appropriate .chk file to the router ♦ Upload either an original Netgear firmware OR a known working DD-WRT .chk file for this router Netgear Firmware Recovery Utility If flashing the router with tftp is unsuccessful, and you have a flashing power light with a ping response of TTL=100, the unit may still be recoverable using the Netgear Firmware Recovery Utility.
  • Page 6 The FCC photos of the internals show a header for both the dome LED and serial port • Reference: OpenWRT WNDR3300 wiki Reference thread for a photo with the pin outs: WNDR3300 serial pinouts • • The pin outs are as follows: Pin 1 = 3.3V (towards the front of the router and should have "1"...
  • Page 7 There have been no known reports regarding the router itself suffering from bad capacitors. Internal antennas Netgear advertised 8 antennas, but while 8 are etched on the PCB, even the official FCC info lists 5 active. Three of the five active antennas are for the wl0 radio, supporting 2.4GHz or 5GHz bands.
  • Page 8 See separate section on known GPIO information What do the front LEDs mean and how do they indicate status? Reference WNDR3300 one activity LED flashes infrequently (credit for partial paste for below) ♦ Power (not directly labeled) - The power light blinks when it is starting up or the restore factory settings button is pressed.
  • Page 9 Netgear_WNDR3300 Original Netgear firmware flashed the dome lights based on various activities on the wireless radios, etc. DD-WRT automatically turns off the dome lights on boot up with code changes since builds around Nov 2008 Reference Changeset 10994 GPIO information Known GPIO pin support from the main support thread (rafale12): •...
