This wireless LAN router with an internal 4 port switch and an internal DSL modem is mostly sold from Alice DSL in Berlin, Germany and Hamburg, Germany.

Only few hardware details are known. The device is based on a Broadcom chipset with an onboard 802.11g wireless.

You can download firmware from the Thomson website: http://www.thomson-broadband.co.uk/codepages/content3.asp?c=7&ProductID=511

The latest firmware is an actual binary file used to flash this device. Searching through the strings in this image file you can find references to "ipkg":

$ strings  585v6_UK_62T2.bin|grep ipkg
q3ipkg2_sign(in=7=2594287[byte], out=1=2594638[byte]) (ipkg2-header=351[byte])

Does this mean there is some Linux code running here?

The memsize should be 16MB, but the flashsize is 4MB - strange.

After connecting an RS-232 transceiver one can see the following in the terminal (9600 1N8):

Unzipping started

 UNZIP DONE -> starting bootloader


 Speedtouch initialization sequence started.

I think my router is broken or the firmware is corrupt because the red led (D503) doesn't stop shining and the terminal continuously prints the upper printout. (Unzipping started, …)
