About Efficient Networks
The Efficient Networks records here run across the Speedstream line.
Reaching the login page
Point a browser at whatever your computer reports as its default gateway. On Windows that is the Default Gateway line from ipconfig; on macOS, Network settings shows it under the active connection.
What the Efficient Networks defaults look like
login is the username on 3 of the 7 entries. 4 of them ask for no username at all. Where one is set, admin comes up most often, on 4 entries.
3 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 Efficient Networks 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.
