DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details. 1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now. 2) OpenWrt support for this device has ended in 2022. 19.07.10 was the last official build for 4/32 devices. The Netgear DG834G v3 is an AR7-based ADSL router with 802.11g wireless and ADSL2+ support. It has a 4-port switch, and the wireless antenna is connected to an RP-SMA connector at the rear.

It contains an example and a couple of explanations. Terminal Installation Process Information abput installing OpenWrt on the DG834.v3 can be found in the oldwiki under installing.openwrt. Upgrading OpenWrt → generic.sysupgrade If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing. Basic configuration → Basic configuration After flashing, proceed with this. Set up your Internet connection, configure wireless, configure USB port, etc. Specific Configuration Failsafe mode The Netgear firmware supports the Netgear recovery mode, which is documented on Netgear's website. Hold down the reset pin and power on, continuing to hold the pin in until the power and tick LEDs blink alternately. Hardware Info Architecture: MIPS Vendor: Texas Instruments bootloader: ADAM2 (possible to flash PSPBoot) System-On-Chip: Texas Instruments TNETD7200ZDW CPU/Speed 4KEc / 211MHz Flash-Chip: Macronix 29LV320 Flash size: 4 MiB RAM: 16 MiB Wireless: Texas Instruments, TNETW1350A (VLYNQ-attached) (no all models) Ethernet: Marvell, 88E6060-RCJ1 (6-port switch controller) swconfig Internet: ADSL, ADSL2+, ANSI T1.413, G.DMT, G.Lite (ITU Annex A; Annex B version is DG834B) USB: No Serial: Yes JTAG: Yes Photos Model Number Front: https://picasaweb.google.com/lh/photo/87Te9ScA6CNNBXmbLsM7vg Back: Opening the case Note: This will void your warranty! There are four screws under the rubber feet. The feet are not glued to the plastic and can easily be removed and pushed back into place once reassembled. The feet have rubber tethers, but you can slide them out gently without damaging them, and later you can reinsert them just as easily. Don't forget to put them in a plastic baggie so you don't lose them! Main PCB Serial → port.serial general information about the serial port, serial port cable, etc. How to connect to the Serial Port of this specific device: The serial port runs at 115200baud, 8 data bits, 1 stop bit and no parity. BE WARNED that you should not run the VCC line to the VCC line on your TTL to RS232/USB adapter. Only wire up RX, TX and GND. The DG834G will happily draw power from the VCC line when its own power is not connected - 3.3V is enough for the LEDs to light up, 5V is enough for ADAM2 to start running! If you use an FTDI USB to TTL serial adapter, the power it consumes is enough to force the serial board to disconnect from the USB due to excessive current draw, which is incredibly inconvenient when trying to capture the bootloader messages (minicom quits when ttyUSB0 disappears). JTAG → port.jtag general information about the JTAG port, JTAG cable, etc. How to connect to the JTAG Port of this specific device: Debricking → generic.debrick Bootloader Mods you could read about bootloader in general It is possible to flash a PSP bootloader.
