About Billion
Billion makes ADSL and VDSL routers widely sold in the UK, Australia and Taiwan.
Reaching the login page
The admin page on most Billion units answers at http://192.168.1.254. If that address does not load, the router is whatever your computer lists as its default gateway — ipconfig on Windows or ipconfig getoption en0 router on a Mac will tell you.
What the Billion defaults look like
Usernames vary; admin is the one that appears most, on a single entry. One entry asks for no username at all. One model shipped with no password at all.
All of them are reached over a protocol that puts the password on the wire in clear text, so work from a machine on the same wired network rather than across the internet, and change the password once you are in.
If the Billion password has already been changed
There is a recessed reset button on the back or underneath that needs a straightened paperclip. Hold it in for thirty seconds with the unit powered on. Let go when the lights change pattern, and give it a couple of minutes to come back up.
A reset clears more than the password. The Wi-Fi name and key go back to what is printed on the label, port forwards and firewall rules are discarded, and any static addressing is lost. Photograph the settings pages first — it takes two minutes and saves an evening.
