More Information

You can go to support.zyxel.com to find other information on the Zyxel Device.

To make your ZYXEL VMG3625-B10C more secure and to manage it more effectively, you should regularly do the following:

• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.

• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Zyxel Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Zyxel Device. You could simply restore your last configuration.

The LED indicators on your ZYXEL VMG3625-B10C provide information about its status. If none of the LEDs are on, the device is not receiving power. The behavior of the LEDs can vary between models. Below is an example description for the VMG3925-B10C model:

Transceiver Installation

Use the following steps to install an SFP transceiver.

1. Locate the transmit (Tx) and the receive (Rx) markings on the SFP+ module to identify the top.

2. Insert the transceiver into the slot.

3. Press the transceiver firmly until it clicks into place.

4. The Zyxel Device automatically detects the installed transceiver. Check the LEDs to verify that it is functioning properly.

5. Close the transceiver’s latch (the latch styles vary).

6. Connect the fiber optic cables to the transceiver.

Transceiver Removal

Use the following steps to remove an SFP transceiver.

1. Remove the fiber optic cables from the transceiver.

2. Open the transceiver’s latch (the latch styles vary).

3. Pull the transceiver out of the slot.

If the wireless network is turned off, press the WiFi button. Check the WLAN/WPS LED on the front panel to see if the wireless network is active.

You can also use the WPS button to quickly set up a secure wireless connection between the Zyxel Device and a WPS-compatible client by adding one device at a time.

To activate WPS:

1. Make sure the POWER LED is on and not blinking.

2. Press the WPS button and release it.

3. Press the WPS button on another WPS-enabled device within range of the Zyxel Device. The WLAN/WPS LED flashes amber while the Zyxel Device sets up a WPS connection with the other wireless device.

4. Once the connection is successfully made, the WLAN/WPS LED shines blue or green.

To turn off the wireless network, press the WiFi button. The WLAN/WPS LED turns off when the wireless network is off.

If you forget your password or cannot access the Web Configurator, you will need to use the RESET button to reload the factory-default configuration file. This means that you will lose all configurations that you had previously. The password will be reset to the factory default (see the device label), and the LAN IP address will be “192.168.1.1”.

1. Make sure the POWER LED is on (not blinking).

2. To set the device back to the factory default settings, press the RESET button or until the POWER LED begins to blink and then release it. When the POWER LED begins to blink, the defaults have been restored and the device restarts.

The duration to press the RESET button varies by model. Refer to your device-specific documentation for exact timing.

To attach your ZYXEL VMG3625-B10C to a wall, do the following:

1. Drill into a wall two holes 3 mm ~ 4 mm (0.12″ ~ 0.16″) wide, 20 mm ~ 30 mm (0.79” ~ 1.18”) deep and 126mm apart. Place two screw anchors in the holes.

2. Screw two screws with 6mm ~ 8 mm (0.24″ ~ 0.31″) wide heads into the screw anchors. Do not screw the screws all the way in to the wall; leave a small gap between the head of the screw and the wall. The gap must be big enough for the screw heads to slide into the screw slots and the connection cables to run down the back of the Zyxel Device.

3. Use the holes on the bottom of the Zyxel Device to hang the Zyxel Device on the screws.

Note: Wall-mount the Zyxel Devices vertically. Attach the bracket to your Zyxel Device with the bracket holes facing down. Make sure the screws are securely fixed to the wall and strong enough to hold the weight of the Zyxel Device with the connection cables.

To use the Web Configurator, you need to allow web browser pop-up windows, and have JavaScript and Java permissions enabled (which are on by default).

1. Make sure your Zyxel Device hardware is properly connected.

2. Launch your web browser. If the Zyxel Device does not automatically re-direct you to the login screen, go to http://192.168.1.1.

3. A password screen displays. Select the language you prefer.

4. To access the administrative Web Configurator and manage the Zyxel Device, type the default username admin and the randomly assigned default password (see the device label) in the password screen and click Login. If you have changed the password, enter your password and click Login.

5. The first time you log in, you will be prompted to change the password. Enter a new password, retype it to confirm, and click Change password. If you prefer to use the default password, click Skip.

You can use the Quick Start wizard to configure your device’s time zone, basic Internet access, and wireless settings.

1. Click the Wizard icon in the side bar to open the Wizard screens. Click Let’s Go to proceed.

2. Time Zone: Select the time zone of your location. Click Next.

3. Internet: Connect an Ethernet cable, a DSL cable, or a USB dongle for Internet access. The device will check the status automatically. Click Next. If your Internet connection is unsuccessful, you may need to enter your connection information manually.

4. Wireless: Turn the wireless LAN on or off. If on, you can set the WiFi Name (SSID) and WiFi Password. You can choose to use the same SSID for both 2.4GHz and 5GHz bands. Click Done.

Your ZYXEL VMG3625-B10C will save your settings and attempt to connect to the Internet.

1. The default LAN IP address is 192.168.1.1.

2. If you changed the IP address and have forgotten it, you might get the IP address of the Zyxel Device by looking up the IP address of the default gateway for your computer. To do this in most Windows computers, click Start > Run, enter cmd, and then enter ipconfig. The IP address of the Default Gateway might be the IP address of the Zyxel Device (it depends on the network), so enter this IP address in your Internet browser.

3. If this does not work, you have to reset the device to its factory defaults.

1. See the cover page of the user guide or the device label for the default login names and associated passwords.

2. If those do not work, you have to reset the device to its factory defaults.

1. Make sure you are using the correct IP address. The default is 192.168.1.1.

2. Check the hardware connections, and make sure the LEDs are behaving as expected.

3. Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java enabled.

4. If it is possible to log in from another interface, check the service control settings for HTTP and HTTPS (Maintenance > Remote MGMT).

5. Reset the device to its factory defaults, and try to access the Zyxel Device with the default IP address.

6. If the problem continues, contact your network administrator or vendor.

1. Make sure you have entered the password correctly. See the cover page for the default login names and associated passwords. The field is case-sensitive, so make sure [Caps Lock] is not on.

2. You cannot log in to the web configurator while someone is using Telnet to access the Zyxel Device. Log out of the Zyxel Device in the other session, or ask the person who is logged in to log out.

3. Turn the Zyxel Device off and on.

4. If this does not work, you have to reset the device to its factory defaults.

1. Check the hardware connections, and make sure the LEDs are behaving as expected.

2. Make sure you entered your ISP account information correctly in the Network Setting > Broadband screen. These fields are case-sensitive, so make sure [Caps Lock] is not on.

3. If you are trying to access the Internet wirelessly, make sure that you enabled the wireless LAN in the Zyxel Device and your wireless client and that the wireless settings in the wireless client are the same as the settings in the Zyxel Device.

4. Disconnect all the cables from your device and reconnect them.

5. The Ethernet WAN connection has priority over the DSL connection. The Zyxel Device follows this rule, even if the Ethernet WAN port doesn’t have an IP for Internet connections. Ensure the active connection has a valid internet source.

6. If the problem continues, contact your ISP.

The following factors may cause interference:

• Obstacles: walls, ceilings, furniture, and so on.

• Building Materials: metal doors, aluminum studs.

• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.

To optimize the speed and quality of your wireless connection, you can:

• Move your wireless device closer to the AP if the signal strength is low.

• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones.

• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client.

• Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary.

• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet.

1. Disconnect the USB device.

2. Reboot the Zyxel Device.

3. If you are connecting a USB hard drive that comes with an external power supply, make sure it is connected to an appropriate power source that is on.

4. Re-connect your USB device to the Zyxel Device.
