Inside My Linux DLink G-604T Broadband Modem/Router

Here’s the interior of my DLink G-604T Broadband Router/Modem, I put here just for viewing after the modem stopped working last month.

FYI, I can still telnet to the modem and play with its settings, the only thing that is not working is the DSL broadband connection to Streamyx. DSL G-604T runs MontaVista-based Linux operating system with kernel 2.4.17 and Busybox utilities. This makes G-604T a great choice for firmware hacking, which makes me want to keep this around for awhile for experimentation purpose.

Now I’m using the stock TM Kasda modem, not that fancy though, but it gets me online. I make a new mental note about broadband modems = they tend to overheat on a poorly ventilated areas.

p/s: I’ll probably will get a new modem next month, since the rest of the family is nagging me for wireless connection :p

  1. why did you not water cool the modem after you got it which would mean that the modam won’t overheat.

  2. The firmware uses linux kernel 2.4.22 modified from the Monta Vista project. You can log-in to the modem to access the Linux shell using telnet/ssh to play around with it.

    The same linux kernel is also used on Dlink 604T and Dlink 2640 wifi router.

  3. Since you have opened up your 2640T, may I ask what kind of chipset it is using and is the firmware based on Linux?
