+ | [* orange] The TVS diode, marked D6 on the PCB, is located between the antenna and a large IC on the RJ45 port side of the board. |
+ | [* black] It is a LittleFuse 24V uni-directional TVS diode with J leads (SMBJ24A). Note the location of the white bar on the diode, as it indicates its orientation. |
+ | [* red] Use a multimeter or ohmmeter to test whether the diode has shorted. A shorted diode will read less than 1 Ohm in both directions. A working diode will have significantly higher resistance in one direction than the other. |
+ | [* icon_note] If the diode is not shorted, then there may be another issue, and proceeding further may not help resolve the problem with your access point. |
