| + | [title] Test the TVS diode |
|---|---|
| + | [* orange] The TVS diode is located between the antenna and a large IC on the RJ45 port side of the board. It's PCB marking is ***D6***. |
| + | [* black] It is a LittleFuse 24V uni-directional TVS diode, with J leads (SMBJ24A). Note the location of the white bar on the diode, which marks its orientation. |
| + | [* black] Use a multimeter or ohmmeter to test that the diode has indeed shorted. A working diode will read significantly higher resistance in one direction relative to the other; a shorted one will read less than 1Ohm in both directions. |
| + | [* icon_note] If the diode is not shorted, then something else is wrong, and proceeding further may or may not help fix your access point. |
