We’ve got another Netgear router to take a look at, it’s the Inside the Netgear DG834 v2 Wireless ADSL Firewall Router which is a similar product to the RP614 except it has wireless.

1. Texas Instrument AR7 Chip
Looks like this is a AR7 Chip which seems to control the ADSL side of things according to this link.

2. Marvell 6 Port Ethernet Switch Chip
This chip seems to be the chip that controls the networking side of things. Similar PDF.

3. MX 32 Mbit EEPROM
It seems to be a 32 Mbit EEPROM according to this post.

4. ISSI 128 Mbit Synchronous RAM (SDRAM)
Appears to be a 128 Mbit SDRAM according to the PDF. Seems to be quite a bit for just a router.
CBLT0243 0452

5.Texas Instrument Wireless 802.11g
Another Texas Instruments chip this time for the Wireless card of this router, another MiniPCI like the Netcomm NB9W we looked at too. Link
53PH108 D4

And we are done here. So many parts that could be used for something else if the routers do break, remember to never throw any electronics device in the bin 😛

    Hi I just pulled one of these apart that seems to have been toasted at some point, it still runs but drops out after a while of running needing regular reboots, I was just wondering what I could do with the parts? I play a little with electronics and like you want to learn more.

      Hi, do the caps look bad or have you used a different power adapter?
      For things to do with the parts – you could try accessing the RAM/Flash with your own MCU – having 128Mbit RAM or a 32Mbit Flash seems like it would interesting to try out (maybe there are some small EEPROMs around too). You could also practice your soldering skills by de-soldering the various chips on the board and then re-soldering them.
