Router Connectivity Errors + BSOD

I have been having router problems.

One afternoon, I noticed that my internet was no longer working. So, I figured all I had to do was restart my modem and router and all would be good. I did it in every conceivable manner, to no avail.

I clicked on the network icon for the computer to troubleshoot itself. I have so far received the error messages that the ethernet cable was not plugged in (it was), the modem/router needed to be restarted (they were), and, ""Local Are Connection" doesn't have a valid IP connection".

Sometimes, when I clicked on the network icon to get it to troubleshoot itself, the BSOD would appear and reboot the system.

I have scoured the interwebs and have tried many a differing course.

I learned about the DHCP. So, I tried to go into the router settings while connected to the router. But, I never was able to. I would not connect. I then learned that the default gateway was the address needed, so I looked that up in "ipconfig" to make sure I was entering the correct address. My default gateway was blank..

I got new ethernet cables, to no avail.

I then saw where a bad ac adapter could be the problem. I had a power outage the night before this happened, so I got a new ac adapter. That didn't work either.

As it stands, my ASUS RT-N66R wireless router, even while not connected, has the LED lights on for ports 2 and 3. I have used all the ports in an attempt to fix this. The WAN LED has never been on since this problem began.

When I have my router connected, the flashing LED light for internet on my Motorola SURFboard SB6182 doesn't flash.

So this is where I'm at.

Here is my ipconfig/all when the router was hooked up. Any help at all and I will eternally thankful!

This alone tells you that you have a problem getting an IP address from the DHCP server. Just assign the computer an IP address manually and it should fix this problem in no time.
 
you've had a power cut.

my money is that this power cut has either reset a lot of the router's config to base level (DHCP looks to be off due to the auto conf IP you get)

or, sadly the router didn't survive the power cut and is now non-functional.

try hard coding an IP on to your router's default subnet and try logging into the router using default credentials
