The Woobm is a WiFi-to-serial bridge. This device enables wireless access to RouterBOARD devices which have a USB port but do not have wireless interfaces. The device operates in 2GHz 802.11b/g/n wireless mode and supports both client and access point modes, which can be protected with a WPA wireless password (for some models, check user and wireless passwords on the sticker).


The device accepts power from the USB port of the RouterBOARD device.

First startup

Connect your Woobm-USB to the USB port, open a wireless network with SSID: WoobmAP will be created. Connect to device and open device IP address in a web browser.

Default Woobm-USB IP is

A device running RouterOS will automatically mount as a serial USB device and provide access after successful login.

WEB interface

WEB interface allows access to the serial port from devices equipped with an 802.11b/g/n 2.4GHz wireless module.

Web interface default page is "Home" From the home page, it is possible to connect and configure RouterOS neighbor devices (MikroTik devices in the same network) Press on a device IP address to establish a connection:

By opening the Terminal tab, Woobm-USB will try to emulate the USB serial interface. On a successful attempt "Connection successful! " message will appear above the terminal window. You can enter commands from the keyboard or use key buttons to send out commands through the USB serial interface.

Show keyboard will bring up the keyboard on mobile devices. Extra buttons provide missing keyboard keys for mobile devices.
