This guide applies to UK routers supplied to installers only.
Before you begin
The default Wi-Fi password is publicly available online. Change it during commissioning to secure the installation.
- Ensure the SIM has been activated by Zaptec Support.
- Insert the SIM (if not pre-installed).
- Wait up to 15 minutes for the router to auto-configure and enable Wi-Fi.
- Do not change any settings until auto-configuration is complete—settings made earlier may be overwritten.
1. Connect to the router's Wi-Fi
- Find the Wi-Fi network (SSID): R1520-Wi-Fi. Other models may show a slightly different SSID, e.g. R1510-WiFi, R2110-WiFi-2ghz. Use whichever matches your router label.
- Enter the default Wi-Fi password: w1rele55.
2. Open the router settings
- On your laptop, phone, or tablet, open a web browser.
- In the address bar, type the router’s web (IP) address (printed on the router's label).
3. Log in
- Enter username: admin
- Enter password: RB + last 6 characters of the router’s MAC address (on the label).
Example: if the MAC ends in 4D:B1:A2 → password = RB4DB1A2
4. Change the Wi-Fi password
- In the left menu, click Interface → Wi-Fi.
- Open the Access Point tab.
- Locate the PSK Password field (this is the Wi-Fi password).
- Enter a new, secure password.
- Click Submit (bottom of the page).
- Click Save & Apply (top right).
Complete steps five and six. Clicking only Save & Apply will not save your changes.
5. Final steps
- Connect the charger(s) to Wi-Fi using the new password.
- Forget the network on your phone/laptop when finished to avoid background data use.
- Record the new password in your job notes/handover. You could use the Notes field on the Zaptec Portal Installation to do this.
Data usage warning
SIMs are for EV charger use only. Non-charger devices (phones, laptops) will quickly exhaust data, causing the SIM to be barred and charger connectivity to be lost.
Protect your installation by:
- Always change the default Wi-Fi password during commissioning.
- Remove the site Wi-Fi from your device after setup to prevent automatic reconnection.
- Not sharing the Wi-Fi password with end users unless required for the specific solution.
Troubleshooting
- Wi-Fi network isn’t visible: Wait the full 15 minutes after SIM activation for auto-config, or connect via Ethernet.
- Can’t log in: Use the correct admin format
RB+ last 6 MAC digits (post auto-config). The MAC is on the router label. - Changes don’t stick: Confirm the router has completed auto-configuration; settings made earlier may be overwritten.
