I opened the box and checked some strings printed on the board. Here is a list of identified strings.

Identified:
Wireless NIC: Texas Instruments TNETW1130GVF

I looked at the hardware list and found Castlenet ASW800 and Aztech DSL600EW with the same components. Both are specified as Texas Instruments AR7 boards. So is my router also based on this board and is there a way how i can verify it is the TI AR7 board in my router?

Today I nmaped my router with the OS detection option.

nmap -O 192.168.x.x

Can I take this as evidence that the Topcom router is based on the AR7 board or is indeed the Netgear DG834?

I also added a foto of the board.

This chip belongs to the AR7 family but it is unclear which flavour it is exactly. See there.

SDRAM 16 MBytes from Mosel Vitelic.

NOR Flash 4 MBytes.

Your router uses a chip belonging to the AR7 family but the board is not exactly the one of the DG384.

Hi!

I've got the same router and firmware v4.00 but no telnet function.
Now i've downgraded to v0109 and startet with

http://192.168.0.1/setup.cgi?todo=debug

and then...

telnet 192.168.0.1

but i cannot find helpful informations about firmware and if it is possible to flash with openwrt-firmware.
anny suggestions to find out something more about the modem-router?

so this is the welcome-screen

is there anything else we should know to flash webr@cer with openwrt? (e.g. how to flash it without ftp...)

on the lower right corner is a JP603 as seen on netgear DG834G(B), is this the serial port connector?
couldn't find any picture of netgear PCB with attached serial port/wires!

Could you find which boot loader is used on your device?
There is a list of likely possibilities for your device in section 1.5 of this wiki page.
From there, the description of each bootloader also explain how to reflash (tftp or ftp).

where can i find informations 'bout the bootloader?
i finally tried to flash and using the DG834 tutorial and had "hacked" mtd2.img for adam2 stuff (md5sum is correct!)
...but this router has no WGET and i don't know how to go on...sorry

is this helpful?

ok, i can say it short...very short

ftp://ftp.netgear.de/download/DG834B/DG … .01.31.zip

download and flash to the webracer...it works *strike*

hm...still stuck on getting ftp...i try to fix and tell
but as i understand, there is no wpa support what i do realy need.

So the router also works with Netgear's firmware?
Is there a way to flash the router over a serial connection? I looked at my pictures of the board but I couldn't find any jtag connectors.

yes, it works fine with netgear firmware, i think wlan is more stable and it's a bit faster.

But DON'T EVER try to flash with "openwrt-ar7-2.6-squashfs.bin" otherwise use the following tools and read the manual carefully!
What i was missing to know how to recover:
- switch off the webracer (or DG834GB)
- hold the reset button
- power on the device
- start the tool
- wait an be happy again.

RecoveryTool-Manual
http://www.broadbandreports.com/r0/down … cedure.zip

RecoveryTool-Binary
http://www.broadbandreports.com/r0/down … tility.zip

botwan, is it possible that u dd all (0-4) MTDBLOCKS and upload/send ist for/to me? i finally crashed my wlan i think.
ok...i think its mtd4 what i need...this or just mtd0???

after recovering from bad flash with the RecoveryTool my router is only known as DG834B...not DG834GB

Sorry I don't own the router myself, it's my sister's router. So I can't send it until tomorrow evening. You also have to tell me how to get terminal access to the router because my former attempts failed to login via telnet. Do I have to downgrade to version 1.0 to enable telnet support? I still have Topcom firmware v.4.0 installed.  Btw. how did you flashed your device?

I think the AR7 port doesn't support the router's network switch, yet. Marvel 88E6060 support is still on the TODO list. http://wiki.openwrt.org/AR7Port?highlig … 75f508d60f
But I am still eager to see Openwrt on the Topcom router with wpa2 support.

(Last edited by botwan on 11 Nov 2007, 16:55)

well it is easy:
1) download firmware 1.09 from www.topcom.net (support, downloads, W)
2) upgrade firmware (should named downgrade in this case)
3) http://192.168.0.1/setup.cgi?todo=debug
4) telnet 192.168.0.1
5) cd /tmp
6) dd if=/dev/mtdblock/X of=mtdX.img (X = 0-4)
7) mini_httpd -p 1080
8) in browser http://192.168.0.1:1080/mtdX.img

keep this MTDs in a very safe place, my mtd4 is complete crashed...device is now known as SCFFFFF should be something like SCA2F****
hope that i have the bill for guarante

so, i've now another modem/router (versatel/versanet) called Sphairon AR860E1-B.
For configuration to use as a router http://wiki.mhilfe.de/index.php?title=Sphairon_AR860 some settings are not easy to get and also to save. now the modem is acting like a router, but there are many missing connectors, LEDs. I've opend it and found USB and SERIAL...will start new thread.
