Fixing my Asus RT-N16 router
Coming home yesterday, I discovered my router had completely powered off on its own. When I replugged the power adapter, the router would power on for a few seconds but eventually emit a subtle ‘click’ and power off again. I swapped the power adapter from the same model of router I have working upstairs; still had the same results.
I immediately thought to send an RMA request to Asus. However, I remembered that I replaced the router’s stock firmware to use a version of DD-WRT, which I believed voided the warranty.
Luckily, I was able to find a blog post with a solution to the same problem I was experiencing. With the warranty voided, I figured I would give it a shot.
Upon opening the router, I immediately recognized the same blown capacitor.
I replaced it with a spare 680uF/V25 capacitor I had lying around.
The router is now functioning like normal. I am happy to save myself $75. Thanks NerdyByNature.
