Cradlepoint E100 — login, gateway address and status lights

Q: What is the Cradlepoint E100 gateway address?

The Cradlepoint E100 settings page is at 192.168.0.1. Enter it in a browser address bar on a device connected to the router. You can also use cp.

Q: What is the default username and password for the Cradlepoint E100?

The Cradlepoint E100 has no universal default password. Each unit has its own, printed on it. The description label, in most cases on the bottom of the device — Cradlepoint's own wording. The same value is also the default Wi-Fi password.

Q: What do the lights on the Cradlepoint E100 mean?

The table above lists each Cradlepoint E100 light, what it indicates and the action to take.

Q: How do you reset a Cradlepoint E100?

To reset the Cradlepoint E100: Before you touch the reset button on this model, check the NetCloud licence state — see the warning in the consequence field, because on an unlicensed unit a reset is not recoverable locally. The procedure itself is single-stage: disconnect everything except the power lead, and with the router powered on press and hold the reset button for at least ten seconds. After about ten seconds the modem and Wi-Fi lights blink twice, which is your signal the reset has taken; release the button and allow about two minutes for the reboot. Cradlepoint does not give the button position in its reset article and refers you to the datasheet for it. There are also two software routes: Commands then Restore to Defaults in NetCloud Manager, and System, System Control, Device Options, Factory Reset Router in the local interface. Hold for At least 10 seconds, with the router already powered on rather than held through power-up. Release after the modem and Wi-Fi lights blink twice.. This erases your configuration.

Open a browser on a device connected to your Cradlepoint E100 and go to 192.168.0.1, or cp.

The password is unique to your unit and printed on it — there is no universal default.

The Cradlepoint E100 is a 4G/5G router from Cradlepoint, in UK use c.2021-2026 (end of sale). This page covers the four things people actually come looking for: its settings address, how its login works, what its lights mean and how to reset it safely.

What is the Cradlepoint E100 gateway address?

The Cradlepoint E100 settings page is at 192.168.0.1. Type that into the address bar of a browser — not into a search box, which will just search for the number instead of opening the page.

You can also use cp, which reaches the same page and is easier to remember.

Your device has to be connected to the Cradlepoint E100 itself for this to work — over its Wi-Fi or by cable. On mobile data, or connected to a different network, the address goes nowhere.

Cradlepoint documents a second route that is more useful than the address itself: "if http://192.168.0.1 does not display the login screen, the default LAN IP may have changed. Go to http://cp/." That page is hosted on the router, so it needs no internet access, and it works even when the LAN subnet has been changed — which is the usual reason the numeric address fails. The medium rating is honest about provenance rather than doubt: 192.168.0.1 comes from Cradlepoint's platform-wide access article rather than an E100-specific page, because the E100 quick start guide does not state a default LAN address at all — Cradlepoint expects you to commission the unit through NetCloud Manager rather than locally. Nothing contradicts it.

What is the default username and password for the Cradlepoint E100?

Unique password on the device label

There is no default password for the Cradlepoint E100 that we could publish, because every unit has a different one.

Where to find yours. The description label, in most cases on the bottom of the device — Cradlepoint's own wording. The same value is also the default Wi-Fi password.

The username is admin and the password is unique to your unit. On any router made from December 2018 onwards, and the E100 is far newer than that, Cradlepoint uses the full 14-digit serial number as the default password, and it is case sensitive — in its own example, MM180456800037, the MM is upper case. Read it off the label. Cradlepoint warns specifically that "the default password shown in your router's quick start guide is an example and will not work for your router", which catches people out. One unusual detail once you are in: Cradlepoint makes you change both the username and the password at first login, not just the password, so after commissioning admin is no longer a valid username at all. The minimum is ten characters and you cannot leave the change screen until it succeeds.

If a website offers you a single password that works on every Cradlepoint E100, it is wrong. Those lists copy a per-device password from one unit and republish it as though it were universal.

What do the lights on the Cradlepoint E100 mean?

Here is what each light on the Cradlepoint E100 is telling you, and what to do about it.

Light	What it means	What to do
Powersolid green	Powered on and running normally.
Powerflashing green	Running on battery rather than external power.	Expected in a vehicle or during a power cut. If it is unexpected, check the external supply.
Powersolid yellow	Attention needed. Cradlepoint's examples are a battery below 20 per cent, the default password still unchanged, or the endpoint not registered in NetCloud Manager.	Very often this just means nobody changed the default password. Log into NetCloud Manager and use Remote Connect to see which alert it is before assuming a hardware problem.
Powerflashing yellow	The battery needs replacing, or it holds 60 per cent or less of its original capacity.
Poweroff	Not receiving power.	Check the power source, insert a charged battery, or check the power switch.
Embedded modemsolid green	An active WAN connection is established over cellular.
Embedded modemflashing green	The modem is connecting.	Give it a minute.
Embedded modemsolid yellow	The modem is not active.	Check the SIM is present and provisioned.
Embedded modemflashing yellow	A data connection error — no modem connection is possible.	Check the SIM, the APN and the antennas.
Embedded modemflashing red	The modem is resetting.
Embedded modemoff	The modem is not connected, because it was disconnected manually.
Wi-Fisolid blue	Wi-Fi is on and operating normally on 2.4GHz or 5GHz.
Wi-Fioff	Wi-Fi is not operating.
Signal strengthsolid	4 solid bars — the strongest signal.
Signal strengthflashing	1 blinking bar — the weakest signal. A blinking bar counts as half a bar.	Reposition the antennas or the unit.
Signal strengthflashing	4 blinking bars — the battery door is not installed and the modem is off.	This is not a signal problem. Somebody has opened the SIM or battery door and not refitted it, and cellular will not work at all until they do.
Signal strengthoff	No signal.	Check the antennas and the SIM.
Ethernet portsolid green	A gigabit link with activity on that port.
Ethernet portsolid yellow	A 10 or 100 Mbps link with activity.	If you expected gigabit, check the patch lead.

Two rows here are worth reading twice, because neither is obvious: a yellow power light very often just means the default password has not been changed, and four blinking signal bars means the battery door is off rather than anything to do with signal.

How do you reset a Cradlepoint E100?

What you lose. Read the licence warning first, because it changes what a reset means. Cradlepoint states that "factory resetting an unlicensed device with NetCloud OS version 7.1.0, or later, will return the device to a unknown license state. In this state, the device will not pass internet traffic and will only communicate with NetCloud Manager until the device receives an active license." So resetting an out-of-contract E100 takes the site off the air and you cannot bring it back without buying a licence. On a licensed unit, all configuration reverts to default with two exceptions Cradlepoint names: the NetCloud credentials and the endpoint's registration to the NetCloud service. There is a second surprise — group configuration survives a reset in effect, because "because NetCloud group and individual device configurations supersede a factory reset, you should remove the endpoint from any groups and clear the device configuration before performing a factory reset. Otherwise, the endpoint will receive the same group or device configurations when the factory reset is completed." So a reset may not clear the setting you were chasing.

Before you touch the reset button on this model, check the NetCloud licence state — see the warning in the consequence field, because on an unlicensed unit a reset is not recoverable locally. The procedure itself is single-stage: disconnect everything except the power lead, and with the router powered on press and hold the reset button for at least ten seconds. After about ten seconds the modem and Wi-Fi lights blink twice, which is your signal the reset has taken; release the button and allow about two minutes for the reboot. Cradlepoint does not give the button position in its reset article and refers you to the datasheet for it. There are also two software routes: Commands then Restore to Defaults in NetCloud Manager, and System, System Control, Device Options, Factory Reset Router in the local interface.
Hold it for At least 10 seconds, with the router already powered on rather than held through power-up. Release after the modem and Wi-Fi lights blink twice..
Release, and give the unit a few minutes to restart before trying to connect.

The reflex of resetting a misbehaving router and starting again is the wrong move on an unlicensed E100. Check the licence first.

A reboot is not a reset. A normal reboot keeps every setting, and unlike a reset it carries none of the licence-state risk.

What if you cannot get into the Cradlepoint E100 at all?

Yes, with one important caveat. The default password is on the device label and a factory reset restores it — but only do that after checking the licence state, for the reason above. If the label is missing or illegible, Cradlepoint's documented route is to contact technical support: "if the default password does not appear on the label, is not legible, or the label is missing, contact Technical Support." An administrator with NetCloud access can also reach the device interface through Remote Connect without knowing the local password, which is the cleanest route and avoids the reset entirely — though Remote Connect is one of the features an unlicensed unit loses.

If that does not work, a factory reset will always get you in, at the cost of every setting on the unit.

Worth knowing about the Cradlepoint E100

Factory resetting an unlicensed E100 stops it passing traffic entirely. Cradlepoint states that a reset on NetCloud OS 7.1.0 or later returns an unlicensed device to an unknown licence state in which "the device will not pass internet traffic and will only communicate with NetCloud Manager until the device receives an active license". Troubleshooting an out-of-contract unit by resetting it will take the site off the air, and you will not get it back without buying a licence. Check the licence state first.
Without an active NetCloud licence the E100 keeps routing but is frozen. After a 30-day remediation period the service locks the endpoint into its last known configuration: enterprise routing, some VPN protocols, the zone firewall, basic URL filtering, most LAN protocols and Wi-Fi keep working, but you lose the ability to make configuration changes, to manage it in NetCloud Manager, to upgrade the operating system, and to use Remote Connect, out-of-band management, alerts, reports, logs and the API. Usable as a static router, not manageable, not changeable, and not safely resettable.
Both the username and the password have to be changed at first login, which is unusual — most vendors only force the password. After commissioning, admin is no longer a valid username.
On NetCloud OS 7.24.40 and later the new password cannot match the current or the previous one, and a violation shows up as a confusing "Sync Suspended" error rather than a clear rejection.
A factory reset does not de-register the device from NetCloud, and group configuration is pushed again afterwards unless you first remove the endpoint from its group and clear its configuration. So a reset may not clear the setting you were chasing.
A yellow power light often just means the default password has not been changed. It is not necessarily a hardware fault.
Four blinking signal bars means the battery door is not fitted and the modem is disabled — a very plausible field failure after someone changes a SIM.
All the WAN and LAN ports are programmable, so the printed port labelling is not binding.
Commissioning genuinely requires a NetCloud Manager account: "activating your Cradlepoint router requires logging into your NetCloud Manager account."
End of sale has passed — announced 10 September 2025, effective 11 March 2026 — but support runs to 11 March 2031. Cradlepoint names the E400-5GE and the X20 as replacements.
