  • [SSID & Password Setting]
    How can I connect my mobile devices (or PC) to the OSH after SW installation?

    (1) Select SSID of the OSH you have. Default SSID can be found on the bottom of the OSH (Here we use 208BW300 as an example).
    (2) The password can be found below the location that you find the SSID (or use the SSID and password you changed if you already modified them).
    (3) Input the password to connect to the OSH, and wait until you are connected (The password is case sensitive. Make sure you input right one)


    You can change the SSID and password in Web UI (System  → Wireless Settings). Also the OSH installer provides the option to change them during installation. We recommend you to change them to enhance security (it may be insecure to continue using password that is clearly printed on the OSH itself).
  • [Configuration thru Web UI]
    When I type http://smarthub in the web browser’s address bar, Web UI admin page is not seen.

  • [Internet setting by service type]
    How do I know my internet service type? And how can I set up my internet connection using the OSH installer?

    – Contact your ISP (Internet Service Provider). Your ISP can tell you the service type you are using now.
    – After knowing your internet service type, run the installer. You can see the below menu after finishing Wi-Fi configuration.
    (1) Choose Auto IP address if you are subscribing dynamic IP based service. All things will be done automatically.
    (2) If you are subscribing static IP based service (mostly company network), ask your system manager to get IP/DNS addresses to configure the network.
    (3) If you are subscribing PPPoE (ADSL), enter the ID/password received from your internet service provider.

    See the user manual or quick guide to know the detailed steps.
  • [Configuration with existing AP]
    I am using a wireless AP already. How can I use a new OSH together with existing wireless AP?
    (1) I want to keep existing AP’s connection, and passively connect the OSH to the AP.
    (2) I want to keep existing AP’s connection, and use the OSH separately without connecting to internet (without connecting the OSH to the existing AP through LAN cable).
    (3) I want to OSH as a main AP connected to internet.

    (1) To prevent conflict, IP address of the existing AP and the OSH should be different. if both have the same address (e.g., please change any one’s IP address by changing the second last locate of the IP address making it something like this : or But in most cases, the OSH does not conflict with existing AP/Routers.
    (2) In this case, OSH creates an isolated network that has no connection with the existing AP. To use the OSH’s own functions, you should connect to the OSH, not to the existing AP.
    (3) You can just connect WAN cable to use internet. If you can’t access internet just by doing this, follow the instruction after running the installer in your bundle CD.
  • [Internet is disconnected after running the installer]
    I have a wireless AP already for internet connection. But it doesn’t work after running the installer of the OSH.

    After running the OSH installer, your PC recognizes the OSH as the default AP. So it changes the default internet connection from your existing AP to the OSH.
    (1) In this case, internet connection doesn’t work if the OSH is not connected to internet through LAN cable.
    (2) If you want to connect to internet thru the existing AP, you can choose the existing AP again in the AP list of your PC.
  • [Security setting]
    What kinds of security mode are supported by the OSH?

    WEP, WPA-PSK, WPA2-PSK, WPA/WPA2-PSK(Default Setting) are supported.
  • [WEP security Setting]
    How can I set a WEP security?

    – In OSH, the following two types are available for setting a WEP security;
    You can create up to four keys (Key number 1 to 4).
    → Type 1: 5 digits or 13 digits which contain English letters and numbers
    → Type 2: 10 digits or 26 digits which contain hexadecimal numbers (English letters (A~F) or numbers)
    – Enter the same WEP key value you set in the OSH to the device for wireless access. At this time, enter the key number for the appropriate WEP key as well.
    – For wireless device that doesn’t have a key number entry (for example, a Smartphone), the key number is automatically selected as no. 1 and it is thus necessary to set the key number entry as no. 1.
    – Default key setting should be the same between the OSH and the target device. Make sure to set the same number and password (Most Smartphone support “Default Key 1” only). And also, we recommend using WPA/WPA2-PSK to enhance security.
  • [Factory Reset]
    How can I reset the OSH to “Factory Reset” mode?

    “Factory Reset” can be used when you have troubles with the OSH while setting it thru the WEB UI, and don’t know what to do. The “Factory Reset” function can restore the status when you first bought the OSH. So be careful because this function erases all customized settings you have done after buying it.
    You can find the reset button from the back of the OSH. Use a pin or a ballpoint pen to push the button for more than 5 seconds. Then you can see the CPU LED and USB LED are blinking. Wait until the OSH restores the factory default settings.
  • [Firmware Update]
    How can I update the firmware of the OSH?

    If you have a firmware version newer than “xx01”, then you can use a “Live Update” using the WEB UI. Just connect to the Web UI by typing http://smarthub in your web browser’s address bar, and go to Maintenance ? Firmware Upgrade.

    If you have a firmware version “xx00”, please do the following steps.

    Step 1
    – On your PC’s web browser, visit, and find “F/W Download” for the optical Smart Hub.
    – Click to download the firmware for your region. “TWxx” is for EU, UK, Asia, and etc. “AWxx” is for America.

    – Select “USB FW Upgrade” and click “Download” to save the firmware to your PC.
    – In this guide, we will explain firmware upgrade using a USB memory stick. Please select “WEB UI FW Upgrade” and follow the instruction if you don’t have a USB drive available. “Boot Mode FW Upgrade” is only for advanced users.
    Step 2
    – Plug a USB memory stick into the PC’s USB slot. Create a folder named “se208bwfwupdir” (which means se208bw fw update directory) at the root of the USB memory stick.
    – Copy the downloaded firmware file (208bwfw.tar.gz) to the folder created as above. Make sure that you downloaded the file after selecting “USB FW Upgrade” mentioned in the “Step 1”.

    – Now the USB memory stick for firmware upgrade is ready.
    Step 3
    – Plug in USB drive to the USB port of the optical Smart Hub. Then power on the device by plugging in the power supply.
    – USB LED and the power LED blink simultaneously while the firmware is upgrading.

    – The firmware upgrade takes about 5~10 minutes. The optical Smart Hub will reboot automatically when the firmware upgrade is finished.
    – You can plug out the USB drive when the optical Smart Hub finishes rebooting (when the power LED stops blinking and stays on).
    Step 4
    – You can find the reset button from the back of the OSH. Use a pin or a ballpoint pen to push the button for more than 5 seconds. Then you can see the CPU LED and USB LED are blinking. Wait until the OSH restores the factory default settings
