The investigator next tested installation of the firmware. In particular,
the investigator connected the TPE-NWIFIROUTER to a local network, and
visited \url{http://192.168.10.1/}, logged in, and chose the option sequence:
``System $\Rightarrow$ Backup / Flash Firmware''.
From there, the investigator chose the ``Flash new firmware image'' section
and selected the
``librecmc-ar71xx-generic-tl-wr841n-v8-squashfs-sysupgrade.bin'' image from
the ``bin/ar71xx'' directory. The investigator chose the ``v8'' image upon
verifying the physical router read ``v8.2'' on its bottom. The investigator
chose the ``sysupgrade'' version of the image because this was clearly a
system upgrade (as a firmware already came preinstalled on the
TPE-NWIFIROUTER).
Upon clicking ``Flash image\hellip'', the web interface prompted the
investigator to confirm the MD5 hash of the image to flash. The investigator
did so, and then clicked ``Proceed'' to flash the image. The process took
about one minute, at which point the web page refreshed to the login screen.
Upon logging in, the investigator was able to confirm in ``Kernel Log''
section of the interface that the newly built copy of Linux had indeed been
installed.
The investigator confirmed that a new version of ``busybox'' had also been
installed by using SSH to connect to the router and ran the command
``busybox'', which showed the newly-compiled version (via its date of
compilation).
