I had a problem with my ASUS RTN-16. It would automatically power down about 5 to 6 seconds after boot. I used Toastman firmware. The router would power down at more or less a random time. Sometimes it took 5 seconds, sometimes 5.5 seconds. So, I thought it might be a hardware problem. I opened the router (you've to take the rubber feet away, and you'll see the screws). There is a 680uF, 16V Taiwanese electrolytic capacitor (brand HERMEI) near the power supply connector that looked very much like it exploded. I replaced it with something I had at home (470uF, 25V) and now it's working fine again. I wrote this post to help others (that use google) and that may encounter the same problem. The ASUS RTN16 is an extremely stable device when running toastman 's software, the first real problem I had with it, is this hardware problem.
