I'll have a look at my Zen modem when I get home; according to my notes, it's...
Make Technicolor
Model MediaAccess TG589vn v3
it's not powered up at the moment, as I only have it for disaster
recovery (swap out my Huawei VSDL modem + linux firewall), and have to
revert to a single box modem/router/AP solution.
I'll fire it up and check the firmware version.
I have a Huawei ADSL/VDSL modem on my backup circuit, it's a Huawei
HG633, hardware version H.1.01, software version v1.15t (heavily
talktalk branded).
