Device Connection

What can I do if the signal is weak?

Signal strength can deteriorate due to several reasons. Here are some recommendations on how to improve your signal strength:

Adjust or move the CPE to a different corner or height that is not blocked, for example by a wall or furniture, by bringing it closer to a window or an open area to receive a better signal. Make sure you are not in an enclosed area.
You can compare with the strength of your mobile phone's signal. If your mobile phone's signal is good, try to restore the factory settings on the CPE and try again.

What can I do if my Internet speed is slow?

If the Internet speed from the Wi-Fi router is slow, you can try the following to improve the signal:

Double-check whether a large number of devices are connected to and using the internet connection from the CPE. The problem may also happen when you are using the device during peak traffic times (evenings between 9:00 pm to 1:00 am).
If you are using the device from the Wi-Fi router during mobility, such as in a moving vehicle, Internet speeds may become unstable or slower depending on the strength of the signal received at the location.
You can also check whether you have exceeded your monthly mobile data limit with your carrier.
The increase of CPE temperature can affect the connection speed. The CPE has a built-in overheating protection mechanism. If the temperature is too high, Internet speeds will be automatically limited to stop the CPE from overheating.
Turn off or move the CPE away from other 2.4 GHz wireless network devices and other home electronics (such as microwaves and TVs) that may cause signal interference affecting the CPE.
After readjusting the location of the CPE, you can try to switch off and switch on the CPE again.
Please ensure that there are no physical obstructions (such as cement walls) that may weaken the signal between the Wi-Fi device and the CPE.

What can I do if I'm still unable to connect my device to Wi-Fi?

Check whether the CPE is placed near to any sources of interference or physical obstructions as mentioned above. If so, change the location of the CPE.
Check and make a note of the following setup information for the device you want to connect and the CPE: SSID, encryption method, and encryption key. Your device's SSID and encryption method should be the same as those on the CPE. If the ID and encryption method is different, you need to change the setup information on your device.
If you turn on Media Access Control (MAC) address filtering for the wireless local area network for your CPE, you can go to the Web UI management page to confirm that your device's MAC address is not within the Deny address range.
Make sure the number of users connected to the CPE does not exceed the maximum number allowed.

What can I do if I can connect to the device but I'm unable to access the internet?

Check the settings of the CPE and make sure you have not turned off the Internet access.
Check the signal strength and make sure the area where the CPE is located has network coverage from your mobile data carrier.
Check your network mode and make sure it matches the requirements of your mobile carrier.
Ensure that you have enough credit balance in your account for your mobile carrier.
Check your APN settings because some APNs of the less well-known carriers are not built into the software. To use the CPE with SIM cards of these carriers, you may need to manually set up a new APN.
If the Dynamic Host Configuration Control Protocol (DHCP) server is not turned on but your device is set to obtain an IP address dynamically, this may result in your device not being able to get online. In this case, enable the DHCP server through the Web UI management page.
Check whether you have exceeded the amount of your monthly mobile data limit.
If the problem persists, contact your respective carrier. If you are a customer of unifi Mobile, you can reach out via TM Live chat at unifi.com.my/chat from 8:00am – 12:00am daily. You can also message on Twitter @helpmeunifi, facebook.com/weareunifi or email at help@tm.com.my for further assistance.

How do I manage the devices that can be connected to my Wi-Fi?

You can manage which Wi-Fi devices can connect through Wi-Fi MAC address filtering. Log in to the Web UI management page and choose Settings > WLAN > WLAN MAC Filter. After this function is enabled, enter the MAC addresses you want to block or allow in the MAC address field. Click Apply to begin blocking/allowing.

How do I update the content displayed on the Web UI management page?

Depending on your browser's cache, the content on the Web UI management page for your device may not be up to date. You may manually clear your browser's cache (if you are using Internet Explorer 9, choose Internet Options > General > Browsing history > Delete) and re-launch the Web UI management page.
