Resetting the B315

This works for the B618 as well.

Warning: Resetting this router is a big step and shouldn’t be done without understanding the possible consequences. Some of the settings that are going to change are:

  • The router’s main username and password will revert to admin admin
  • The wireless information such as SSID and internet password
  • If you have made any other setting changes you need to reconfigure them after the reset is finished as well


  • Power off and remove the SIM card.
  • Let the B315 powered on fully then use a pointed object to press and hold the reset button on the back until the light on the front turns white & flashes. This will restore the B315 to its factory settings. After the factory defaults are restored, the B315 will restart automatically.
  • Once restarted power off and plug the SIM card back in
  • Power on – login should be back to admin admin
