Please ensure the right side switch is ON.
When the POWER LED of the repeater is solid on, press the RESET button on the repeater and hold for 8 seconds and then release.
After the POWER LED turns solid on, the repeater is restored to the factory settings. Note: Please ensure pressing the RESET button for 8 seconds after the device is powered on.
The router may be encrypted with WEP or WPA/WPA (Enterprise).
Change the encryption type of the router to WPA-PSK, and try scanning again.
Please check if the situation is before or after the network extension.
1. Before the extension
· Please confirm you are connected to the correct SSID (wireless network) of the repeater.
(see the name of its wireless network on the product label).
· Check if the IP address that entered in the address bar is correct (192.168.0.2).
· If you are unable to log in, please close the browser (not just return) and open a new page to try again.
If it still failed, please clear all the browser cache or reboot your mobile device.
· If none of the above solutions works, it is recommended to restore factory settings or recharging the plug in the socket,
then try connecting and logging in again.
2. After extension
· Make sure that you are connected to the correct SSID (wireless network) of the repeater.
If the SSID of the repeater is the same as the uplink wireless network (SSID of the router),
please check if you are connected to the wireless network of the repeater.
· Then log in to this IP address: 192.168.0.2
· If it failed, please cut off the power supply and reconnect the power supply.
Then try logging in to the above IP address after the repeater extends automatically.
· If it still does not work, please replace with another laptop or mobile phone to log in.
· Make sure you are connected wirelessly (either to the router or to the repeater), and then log in to the Web page of the router;
· Open the Client List to view connected devices. After finding the MAC address (see product label) of the repeater,
you can get the IP address of repeater assigned by the router.
· Open a browser, enter the IP address in the address bar, and then you can access the Web page of the repeater.
Method 3: (recommended)
· Download device firmware file v1.0.2 from juplink.com and conduct firmware upgrade.
· After reset, try logging in to domain name: router.juplink.com
1. Please check if your mobile device can be connected wirelessly to the repeater in the same place, as the signal in this place may be poor.
2. Check if the encryption mode of the uplink router is WEP. Only no encryption, WPA, WPA2 and mixed-mode are supported by this repeater.
3. Check on your mobile device to see if the uplink wireless network is hidden.
· Check if the wireless signal indicator is green or off. Off indicates extension failure.
· If you can't find the uplink wireless network during extension, please try the following:
① Set the SSID of the router and that of the repeater to combinations of numerals and letters.
② Move the repeater closer to the router ( within 1ft is recommended );
③ Ensure that the encryption mode of the uplink wireless network is not WEP. Only no encryption,
WPA-PSK, WPA2-PSK or mixed mode of the above is supported by the repeater.
④ Ensure that the uplink wireless network is not turned off or hidden.
⑤ Log in to the Web page of the router to check if any restriction is made, such as MAC filter, blacklist, etc.
⑥ Ensure that the correct password of the uplink router is entered during extension.
⑦ Modify the wireless network name and password of the uplink router and reset the repeater.
① Check if there is the default SSID. If yes, the extension fails.
② Check the status of the wireless signal indicator. On or flashing indicates successful extension, while off indicates extension failure.
③ Log in to the Web page of the repeater to see if it is in the extended state.
· If you are sure that the extension is successful, keep the antennas upwards and in parallel with the antennas of the router.
If not, please adjust their angle.
· Try putting the repeater and router closer, and check if the indicator becomes solid green.
· Check if the extension is successful (by observing the indicator and Web page).
· Disconnect the device that is without Internet access and connect again to see if it becomes available.
· Log in to the Web page of the repeater and check if the network signal of the uplink router is too weak.
It is recommended to put the repeater in a place where the signal strength is at least between 40%-50%.
· When you are connected to the wireless network of the repeater, check if its SSID is assigned by the router.
· Reset the repeater and try connecting another wireless network.
After the extension, do not put the repeater too close to the router.
Put the repeater in the middle of the router and the farthest place where you want to be connected.
If you want to extend the wireless network horizontally, ensure that the repeater antennas are positioned upwards,
and in parallel to those of the router.
If it is for the duplex house, both the antennas of the repeater and router should be tilted and remain in parallel.
The best performance distance is 5 ~ 30 ft.
· Check the Web page for any restriction or blacklist setting.
· Clear cache of the extended network and then reconnect.
· Reset the repeater and set up again.
· After the first successful setup, the device restarts to accommodate the channel of the extended network.
Wait for about 1 minute before reconnecting.
If the signal indicator becomes off, the repeater is disconnected from the router.
· Please check if any changes have been made on the repeater or the mobile device.
· Access the Web page of the router to view the operation log, and check the status of the uplink router.
· If the router is normal, adjust the location and direction of the repeater.
Check the signal strength indicator on the physical housing of the repeater.
① One LED on: weak receiving signal, strength below 25%.
(In this case, it is recommended to put the repeater closer to the router, and keep their antennas in parallel.)
② Two LEDs on: Good receiving signal, strength between 50~75%.
③ Three LEDs on: Excellent receiving signal.
·In general, the repeater works in its best performance when the strength of the signal that the repeater receives is between 50% and 75%
(when the Web page shows the signal of 3 bars).
·Check the network speed when your mobile device connects to the router directly at that position.
If the wireless network speed of the router is similar to that of the repeater, the connection is normal.
When the wireless network speed of the router is faster than that of the repeater, please check the following:
① Check the location of the repeater. Do not put it at a corner.
② Check if the antennas of the repeater and router are in parallel. Antennas aligned in parallel ensures better connection.
③ If it still does not work, reset the repeater, and try connecting the repeater to the router again.
④ Reset the repeater.
The encryption method used by the Comcast, Verizon router may not be recognized by EC4-1200 Wi-Fi Extender.
Try the following solutions to solve the problem:
① Log in to Comcast, Verizon router and enter the wireless setting page。
② Change the wireless encryption method to WPA/WPA2. or WPA-PSK/WPA2-PSK.
③ Confirm the setting and use EC4-1200 Wi-Fi Extender to search the router signal
