• The communication speed has dropped.

    Please follow the steps below on a periodical basis.

    ■ Rebooting connection devices
    The performance of communication devices may decline when they are kept on for a long period. Please try rebooting your ONU (Optical Network Unit), HUB (splitter), device (computers, smartphones, tablets), to see if there is any improvement.
    When you turn off your router, please wait for about 15 minutes before turning it back on.

    ■ If you are using wireless LAN
    Speed may decrease due to factors such as problems concerning standards of the wireless LAN, interference with other radio waves, structure of the house, etc. If possible, try wired connection to see if there is any improvement.
    If you are using a separate router and wireless LAN device, try connecting to internet directly with the router without connecting through wireless LAN device.

    ■ Checking LAN cables
    Try disconnecting the LAN cable and connect again. If you are using a long cable, please check to see if no furniture etc. is placed on top of the cable.

    ■ If you are using multiple devices
    Please try connecting with other computer or tablet. If you see an improvement with other devices, the reason is particular to the device with which you want to improve the communication speed. Please contact the manufacturer of the device.
