EC3-750 Wi-Fi Extender
Troubleshooting
A2:
Q1:
How to reset the repeater?
A1:
When the POWER LED of the repeater is solid on, press RESET button (for about 5sec)
until the WPS LED flashes. After the POWER LED turns solid on again, the repeater is restored to
the factory settings.
Why is my power light off after connecting the extender to power supplies?
Please ensure the right side switch is ON.
Q2:
Q3:
A3:
Q4:
Why can’t the repeater find the Wi-Fi network of my router/modem,
such as Comcast,Verizon?
A4:
The encryption method in the Comcast,Verizon router may not be recognized by EC3-750 Wi-Fi Extender.
Try the following to solve the problem:
①Log in to Comcast or Verizon router and enter the wireless settings page.
② Change the wireless encryption method to WPA/WPA2 or WPA-PSK/WPA2-PSK.
③ Confirm the settings and use EC3-750 Wi-Fi Extender to search the router signal.
Why does it fail to log in to Web page of the repeater?
Please check if the situation is before or after network extension.
a. Before 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 information entered in the address bar is correct (192.168.3.1 or router.juplink.com).
• 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 work, it is recommended to restore the repeater to factory settings or
recharge the plug in the socket, then try to connect and logging in again.
b. After extension
Method 1:
• Make sure that you are connected to the correct SSID (wireless network) of the repeater.
• Then log in to this address: router.juplink.com
• If it failed, please cut off the power supply and re-connect it. Then try to log in to the above
address after the repeater extends automatically.
• If it still does not work, please use another laptop or mobile phone to log in.
Method 2:
• Make sure you are connected wirelessly (neither to the router nor 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.
• This IP address is the updated login address of the repeater.
Why can l find someone else's Wi-Fi network, but not mine?
• Check if the encryption mode of the uplink router is WEP. Only no encryption, WPA, WPA2 and
mixed mode are supported by this repeater.
• Check on your mobile device to see if the uplink wireless network is hidden.
Q5:
A5:

Q6:
A6:
Q7:
Why does it always prompt for failure during extension?
A7:
• 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:
①Set the SSID of the router and that of the repeater to combinations of numerals and letters.
②Move the repeater closer to the router (within 5ft is recommended).
③Ensure 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.
④Ensure that the uplink wireless network is not turned off or hidden.
⑤Log in to the Web page of the router to check if any restriction is made, such as MAC filter,
blacklist, etc.
⑥Ensure that the correct password of the uplink router is entered during extension.
How can I know if the extension is successful?
①Check if there is the default SSID. If yes, the extension fails.
② Check the status of the wireless signal indicator. If the indicator is on or flashing,it indicates
successful extension.If the indicator is off,it indicates extension failure.while off indicates extension failure.
③Log 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 signal strength indicator becomes
solid green.
Q8:
A8:
A9:
• Check if the extension is successful (by observing whether the signal indicator lights up.
If not, please reset the repeater, and try extending again.).
• Disconnect the device which loses 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%.
• Check the location of the repeater. Do not put it at a corner.
• Reset the repeater and try connecting to another wireless network.
Q9:
Why is there no Internet access after extension?
Why is the extended signal poor, even lose connection to the repeater
after extension?
• Do not put the repeater too close to the router, also do not put it at a corner.
• For better performance, plug the extender into an outlet about halfway between the router and the
Wi-Fi dead zone. The location you choose must be within the range of your existing Wi-Fi network.
• If you want to extend the wireless network horizontally, ensure that the repeater’s antennas are
positioned upwards, and in parallel to those of the router.
• If it is for 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.
A10:
Q10: Why does the wireless network show strong signal strength
but low speed after extension?.
① Check the signal strength indicator on the physical housing of the repeater.
In general, the repeater works in its best performance when the strengh of signal that the repeater
receives is between 50% and 75% (when the indicator shows the signal of 3 bars).
② Check the location of the repeater. Do not put it at a corner.
③Check if the antennas of the repeater and router are in parallel. Antennas aligned in parallel ensure
better connection.
④ If it still does not work, reset the repeater, and try connecting the repeater to the router again.
Note: When the Extender is working in repeater mode, it does not boost your network speed,
but supports wider wireless coverage, that is, you can enjoy Wi-Fi connection where your
router signal may not reach directly.
