D-Link DIR-890L Power Adapter Port Replacement

简介

The power adapter port is on the back of the router. This is where the power cable plugs into your router, and then plugs into the wall. If this port is damaged in any way, the cable cannot be plugged in and thus you will not be able to give power to your device.

This guide requires desoldering, which is an advanced skill.
