This Toshiba model has atheros lan and broadcom wifi chips, siduction 2013.2 and 2013.1 does'nt see any networks interfaces at all, as well as does'nt work su, sudo commands, and installer.
I've replaced hdd in Lenovo T500, have installed 2013.2, firmware-atheros and firmware-brcm80211 packages. After it I've back hdd in Toshiba and all works for me.
