Setting up the Gemtek / Browan TTIF Indoor Femto LoRaWAN Gateway (WLRGFM-100) in 15 minutes

For model WLRGFM-100. Use Wi-Fi only, or use Ethernet with a tested Wi-Fi alternate connection.

Use this guide to connect a Gemtek / Browan WLRGFM-100 gateway that BARANI or your installer has already configured. The guide covers only the gateway’s Internet connection.

Use Wi-Fi as the main Internet connection when Ethernet is unavailable. When Ethernet is available, connect Ethernet first, then save Wi-Fi as an alternate connection and verify that connection once by unplugging Ethernet.

Setup is complete when: the Power, WAN, Wi-Fi, and LoRa lights are all solid green, and a new sensor message appears in the monitoring system supplied by BARANI or your installer.

Scope: This guide does not configure the LoRaWAN sensor network. LoRaWAN is the low-power, long-range wireless network used by the sensors to reach the gateway.

Wi-Fi only: about 10 minutes

Ethernet plus Wi-Fi test: about 15 minutes

First: make sure this is the correct gateway

The case, bottom label, invoice, or older instructions may use different names for the same unit:

• Gemtek — the manufacturer name found on some older units and regulatory records.
• Browan Indoor Femto Gateway or IoT Femto Gateway — the product and manual names used by Browan.
• WLRGFM-100 — the model number to check on the bottom label.
• BARANI TTIF — the short name used in BARANI instructions.

Do not use a TTIG setup guide for this unit. The Things Indoor Gateway, shortened to TTIG, is a different plug-in gateway with one multicolor light. The WLRGFM-100 in this guide has an Ethernet port, an external LoRa sensor-network antenna, and four separate front lights.

Use only the screens shown in this guide. Do not update the gateway firmware, which is its internal software. Do not press and hold RESET or change any other gateway setting.

Before you begin: place the gateway indoors or in a fully sheltered location

BARANI recommends installing this indoor, non-weatherproof gateway inside a building.

Use a porch or vestibule only when all three conditions are met:

1. The temperature remains above 0 °C (32 °F).
2. Direct sunlight cannot reach the gateway.
3. Rain, drizzle, wind-driven moisture, splashes, and condensation cannot wet the gateway.

• Place the gateway on a stable shelf with open air around it.
• Keep the LoRa sensor-network antenna upright and away from large metal cabinets.
• Keep the gateway away from sinks, wet walls, open windows, heaters, and direct sunlight.
• Use the supplied 5 VDC / 2 A power adapter.
• Label the power and Ethernet cables “GATEWAY — DO NOT UNPLUG.”

This guide is for the Gemtek / Browan WLRGFM-100 Indoor Femto gateway, called the BARANI TTIF in older instructions. Correct normal operation is shown here: the Power, WAN, Wi-Fi, and LoRa indicators are all solid green.

Choose the Internet connection

NO ETHERNET AVAILABLE

Use Wi-Fi as the main Internet connection

Leave the Ethernet port empty and complete all Wi-Fi steps below.

ETHERNET AND WI-FI AVAILABLE

Connect Ethernet first, then save Wi-Fi as an alternate connection

Connect Ethernet, then complete the same Wi-Fi setup. After setup, unplug Ethernet once to verify that this gateway can use the saved Wi-Fi connection under the current installation conditions.

Before starting, have these ready: the building’s 2.4 GHz Wi-Fi name, its Wi-Fi password, and a phone, tablet, or computer with Wi-Fi. Wi-Fi passwords are case-sensitive.

1

Step 1: Attach the LoRa antenna, connect Ethernet if needed, then connect power

Attach the external LoRa sensor-network antenna before applying power. For Wi-Fi-only service, leave the Ethernet port empty. For Ethernet plus Wi-Fi, connect Ethernet now. Plug in the power adapter and wait until the Power light stops blinking and remains solid green.

2

Step 2: Confirm WLRGFM-100 and note the final six MAC-address characters

Confirm that the model is WLRGFM-100. Find the line labeled MAC. The MAC address is the gateway’s 12-character hardware address. Write down its final six characters, ignoring colons or hyphens.

Example: when the MAC address ends in 2C:53:FF, the temporary setup Wi-Fi name will normally be AP-2C53FF.

Confirm that the model is WLRGFM-100. The temporary setup Wi-Fi name normally ends with the final six characters of the MAC address shown on the bottom label.

Connect to the gateway’s temporary setup Wi-Fi

3

Step 3: Select the temporary gateway Wi-Fi network named AP-XXXXXX

On your phone, tablet, or computer, open Wi-Fi settings and select:

AP-XXXXXX

The six characters represented by XXXXXX should match the final six characters of the MAC address on the bottom label. This match identifies the correct gateway when more than one gateway is nearby.

“No Internet” is normal at this step. Stay connected to AP-XXXXXX. This temporary Wi-Fi network creates only a local setup connection between your phone, tablet, or computer and the gateway.

If your phone automatically leaves the temporary network, reconnect to AP-XXXXXX and choose the option that means stay connected or use without Internet.

Select the temporary AP-XXXXXX setup network. Its final six characters should match the final six characters of the gateway MAC address. A “No Internet” warning is normal at this step.

Open the local setup page and sign in

4

Step 4: Open the gateway’s local address

While still connected to AP-XXXXXX, open Chrome, Safari, Edge, or Firefox. Type this address into the browser’s address bar, not into a search box:

http://192.168.55.1

A “Not Secure” label is normal for this local setup page. Continue only when the address is exactly 192.168.55.1. Do not bypass a warning for any other address.

5

Step 5: Use the factory-default administrator login

Username: admin

Password: admin

If admin / admin does not work, the installer may have changed the administrator password. Ask the installer or BARANI support. Do not factory-reset the gateway merely to regain access.

Do not confuse these three items

Temporary gateway network: AP-XXXXXX

Select this name in your phone or computer’s Wi-Fi settings.

Gateway administrator login: admin / admin

Enter these credentials on the page at 192.168.55.1.

Building Wi-Fi password: your own password

Enter this password later in the field labeled KEY.

While connected to AP-XXXXXX, open 192.168.55.1 and sign in with the factory-default username admin and password admin.

Save the building’s 2.4 GHz Wi-Fi connection

6

Step 6: Open Network → WAN → Wireless Extender

In the left menu, select Network, then select WAN. WAN means wide area network; this is the gateway’s Internet-connection page. At the top of the WAN page, select Wireless Extender.

7

Step 7: Enable the Wireless Extender and scan for Wi-Fi networks

Set Extender mode to enable. Click SCAN to display nearby Wi-Fi networks.

8

Step 8: Select the building’s 2.4 GHz Wi-Fi and enter its password

Select the building, home, or office 2.4 GHz Wi-Fi network. The Wi-Fi name field, labeled SSID, should fill in automatically. SSID is the technical name for a Wi-Fi network name.

Leave the detected Security setting unchanged unless the network administrator tells you otherwise.

Enter the building’s Wi-Fi password in the field labeled KEY. Check uppercase letters, lowercase letters, numbers, and symbols carefully.

9

Step 9: Save the building’s Wi-Fi connection

Scroll to the bottom-right of the page and click SAVE. The setup page may pause or disconnect while the gateway changes network connections. Return your phone or computer to its normal Wi-Fi afterward.

Stop after clicking SAVE. Do not change any other page or setting. Do not update firmware or press and hold RESET.

Go to Network → WAN → Wireless Extender.

In Network → WAN → Wireless Extender, set Extender mode to enable, click SCAN, select the building’s 2.4 GHz Wi-Fi, enter its password in KEY, and click SAVE.

Confirm the connection and test Wi-Fi without Ethernet

10

Step 10: Wait until Power, WAN, Wi-Fi, and LoRa are all solid green

Give the gateway time to finish reconnecting. The correct normal result is four solid green lights: Power, WAN, Wi-Fi, and LoRa.

Where to verify sensor data: Open the monitoring system supplied by BARANI or your installer—for example, the allMETEO portal when allMETEO is used for this installation. A reporting interval is the normal time between sensor messages.

Wi-Fi-only installation: after all four lights become solid green, wait one full reporting interval and confirm that a new sensor message appears in the monitoring system. The four green lights confirm the gateway status; the new sensor message confirms end-to-end data delivery.

Ethernet plus Wi-Fi installation: perform this test once

1. Start with Ethernet connected. Confirm that all four lights are solid green and that a new sensor message appears in the monitoring system.
2. Leave power connected and unplug only the Ethernet cable from the gateway.
3. Wait for all four lights to become solid green again. Then wait one full reporting interval and confirm that another new sensor message appears in the same monitoring system.
4. Reconnect Ethernet and leave the saved Wi-Fi settings enabled.

If the test fails: reconnect Ethernet, do not reset the gateway, and contact BARANI support. Do not rely on Wi-Fi as an alternate connection until this test passes.

What this test verifies: passing the test verifies a Wi-Fi path for an unplugged or cut Ethernet cable under the current installation conditions. The test does not verify operation during a power outage, router failure, or Internet-service failure.

What the four lights mean

1. Power

Solid green: power is on. Blinking green: the gateway is starting. Solid orange: system error. Blinking orange: firmware is updating—do not unplug the gateway.

2. WAN

Solid green: the gateway received a network address through Ethernet or the saved Wi-Fi connection. Off: the gateway did not receive a network address.

3. Wi-Fi

Solid green: the Wi-Fi radio is enabled. This light alone does not confirm that sensor data reached the monitoring system; WAN and LoRa must also be green, and a new sensor message must appear.

4. LoRa

The front sensor-network indicator is labeled LoRa. Solid green: the gateway is connected to or activated by the LoRaWAN service that receives sensor data. Off: sensor messages may not be reaching that service.

FINAL CHECK: FOUR SOLID GREEN LIGHTS + A NEW SENSOR MESSAGE IN THE MONITORING SYSTEM.

Quick troubleshooting

Problem	What to do
I cannot see AP-XXXXXX	Stand close to the gateway, wait until the Power light is solid green, and confirm that the Wi-Fi light is on. Turn your phone or computer’s Wi-Fi off and back on.
The setup page will not open	Confirm that you are still connected to AP-XXXXXX. Ignore “No Internet.” Enter http://192.168.55.1 in the browser address bar, not a search box. If needed, temporarily turn off a virtual private network (VPN) or mobile-data switching and try again.
admin / admin does not work	The administrator password may already have been changed. Ask the installer or BARANI support. Do not reset the gateway merely to recover the password.
The building’s Wi-Fi is not in the SCAN list	The gateway uses 2.4 GHz Wi-Fi. Confirm that 2.4 GHz Wi-Fi is enabled on the router and move the gateway closer to the router.
The WAN light is off	Check the Ethernet cable, or repeat the Wireless Extender setup and carefully re-enter the Wi-Fi password in KEY.
The LoRa light is off	First confirm that the WAN light is solid green. When WAN is green and LoRa remains off, contact BARANI support. Do not change other gateway settings.
No new sensor message appears	Wait one full reporting interval. When all four lights remain solid green but no new sensor message appears, contact BARANI support and identify the monitoring system you checked.
The Ethernet-unplug test fails	Reconnect Ethernet and leave power connected. Do not reset the gateway. Tell BARANI support which lights are solid, off, blinking, or orange.

Do not press and hold RESET during normal setup. Holding RESET for about five seconds restores factory defaults and erases the saved Internet and LoRaWAN settings.

Secure the administrator login after setup. Ask BARANI support or your installer to change the factory-default password, or change it only after the gateway works and record the new password in a secure place.

Source basis and limits

Manufacturer documentation: Browan’s product page and WebUI guide are the sources for the WLRGFM-100 model, 2.4 GHz Wi-Fi, 5 VDC / 2 A power supply, local setup address, factory-default administrator login, Wireless Extender controls, front-light meanings, and five-second factory reset.

BARANI operational recommendations: BARANI recommends sheltered placement, cable labeling, saving Wi-Fi as an alternate Internet connection, and verifying that connection by unplugging Ethernet once.

Limit of the field test: passing the Ethernet-unplug test verifies the installed gateway, its current configuration, the router, and the Internet connection at the time of the test. The test does not guarantee operation during a power outage, router failure, or Internet-service failure.
