please how to reset the PTP 250 without accessing the GUI.

hi
i enabled the Vlan tagging so i'm not able to access the AP any more.
i need your help to reset the AP to factory default so i can configure again.

thanks

Use the reset plug (supplied in each PTP 250 ‘Link Complete’ or ‘End Complete’ kit) to reset the unit to factory default configuration.

Please refer to user guide http://doc.azenn.com/cambium/CambiumPTP250_UserGuide.pdf 7-25 for detail.

What if I don't have a reset plug.  is there another way to do it?
