I found this page on the Vodafone website that talks about an update to the firmware for this modem, but unhelpfully it doesn't say what version is the latest. There's a download link which goes to http://www.vodafone.co.nz/broadband/firmware%20 but this comes up with a 404 error, probably because of the %20 on the send of the URL. If I remove the %20 from the URL then I get a page that says "Method Not Allowed" and that's all.
Accoding to the modem it's using Software Version V100R001C12B037. Can anyone tell me if this is the latest or where I can look to find the latest firmware?
