This router is very similar to other devices using the same Broadcom 96348 hardware (ADSL2+, 802.11g), like:

• USR 9107/9108
• Hitachi SpeedWeb
• Linksys WAG54GX2
• Telsey "Alice W-Gate" and Pirelli "Alice-W-Gate+" rented by "Telecom Italia" to ADSL customers (also found, cheap, sold on many radio-rally).

This device runs Linux. A firmware upgrade is available on the Asus Site. It is a squashed filesystem with some other data appended to it - a kernel? The squashfs is 2.0 and uses an LZMA Broadcom-flavour compression method so, normally, only file listing is possible.

$ file squash squash: Squashfs filesystem, big endian, version 2.0, 2664561 bytes, 678 inodes, blocksize: 65536 bytes, created: Thu Jul 20 10:32:10 2006

Tryng to read files gives the following error in syslog:

SQUASHFS error: lzma returned unexpected result 0x1

You can find here a patched squashfs-LZMA kernel module that correctly mounts the Broadcom filesystem (used to extract the italian Telsey firmware):

Asus, like other, now has correctly put online the GPL source code:

The stock firmware runs a 2.6.8.1 kernel and a bunch of other binary modules are in /lib. See the File Listing for details.
