Dear Derwyn,
Thank you for your email, in regards to your question, we do not have any official drivers or support for the Linux Operating system. However you should be able to still use the Ethernet port on the unit to connect to your computer up to the modem as it does not require any drivers for its use.
Kind Regards,
