Acest articol corespunde cu:

If you have already tried to configure the Powerline adapters but failed, please check the following troubleshooting.

Below is an example of a normal topology of Powerline network and takes MP510 KIT as a demonstration.

 

Please refer to the LED explanation (MP510 as an example) and do troubleshooting.

 

Case 1: The LED light is still Blinking slowly after configuration

 

Step 1. Verify the Powerline devices are in the same electric circuit.

If the Powerline units can be paired in the same room, but when moving one to another area, the Powerline light is blinking slowly, it usually that means they are plugged into different circuits, which preventing them from communicating. In this case, the Powerline device may not be suitable for your house, please consider other products, like range extender, access point, etc.

Note:

*Better to plug Powerline devices into wall sockets, not different power strips.

*Bring both powerline devices into the same room for configuration. Once set up, move the second powerline device to where you need it.

 

Step 2. Reset the Powerline devices and pair again.

 

Step 3. Try different methods for configuration.

 

Step 4. Upgrade to the latest firmware and repair them.

Step 5. Check the IP Address and Default Gateway information of the Powerline device.

Please connect one of your end devices(computer, laptop, mobile phone, etc.) to the Powerline device (wired or wireless), then check the IP Address and Default Gateway. 

a. If the Default Gateway is 192.168.0.254

1. Please connect the same end device to the wireless router, then check the IP Address and Default Gateway.

Note: For iPhone, “Router” means “Default Gateway”.

2. Configure the information on the Powerline extender’s management page to refer to the IP information of the end device got from router.

Go to Advanced->Device Settings->LAN Settings.

 

b. If the Default Gateway is the same as the wireless router

1. Make sure the main router doesn’t enable any security settings, like MAC Filtering or Access control.

2. Connect your computer to the Powerline and ping the Default Gateway of wireless router (Optional).

 

Please contact Mercusys technical support with the following information if you still cannot have internet access after the above suggestions.

1) The model number of your router and Powerline adapters.

2) Whether you have tried all suggestions listed above or not. If yes, what are they?

3) Detail the network topology of your house.

4) The Ping result(Optional).

 

Case 3 Only wireless connection is not working

 

Please note that MP500 KIT doesn’t support the Wi-Fi.

If all of your devices cannot work properly with the Mercusys device, please do some troubleshooting as per the following instructions.

 

1. Cannot see the Wi-Fi name on the Wi-Fi list

Step 1: If you have pressed the Wi-Fi button on the Powerline extender, it will copy wireless settings from the main router. Please move the Powerline extender to the other place and check if the signal strength of the wireless router is improved.

 

Step 2: Change the wireless settings of the Powerline extender.

Please go to the PLC management page, then click Advanced>>Wireless and change the setting.

 

Step 3: Reset the Powerline units and reconfigure.

How to reset: Press and hold the RESET button/hole for 6s until all lights are flashing.

 

Please contact Mercusys technical support with the following information if you still cannot have internet access after the above suggestions.

1) The model number of your router and Powerline adapters.

2) Whether you have tried all suggestions listed above or not. If yes, what are they?

 

2. Can see the Wi-Fi name but unable to connect

Step 1. Try different wireless channels. 

Connect a wired computer directly to the Powerline Extender, then please go to the PLC management page, then click the Advanced>>Wireless>>Wireless setting.

Note: Please change the channel to 1 or 6 or 11.

 

Step 2: Change different Network name(SSID) and password.

 

Step 3: Disable the special settings, like MAC Filter or Parental Control if you have set up before.

 

Step 4: Reset the Powerline device and wait for the indicators to stable, then try to use the default password of the Wi-Fi printed on the label to connect the Wi-Fi. If succeed, reconfigure the Powerline device.

Normally the default SSID would be mercusys_XXXX.

 

3. Can Connect to the Wi-Fi but no internet

 

Step 1: Restart the Powerline extender and end device, then check again.

 

Step 2: Forget the network and reconnect.

 

Step 3: Upgrade to the latest firmware.
