About ZyXEL
ZyXEL is a Taiwanese maker of DSL modems, business gateways and the long-running Prestige line. The ZyXEL records here run across the Prestige and GS- lines.
Reaching the login page
The admin page on most ZyXEL units answers at http://192.168.1.1. 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.
The Prestige series often uses a numeric password such as 1234 rather than a word.
What the ZyXEL defaults look like
admin is the username on 10 of the 21 entries. 7 of them ask for no username at all. One model shipped with no password at all.
Where one is set, 1234 comes up most often, on 15 entries. 10 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 ZyXEL 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.
