You might have to try a "Hard" reset back to default setup and then reconfigure what you need.  Do a web search for "ASUS RT-N16 hard reset" to find instructions.  But here are some questions for you too:

Are you using a wired ethernet connection to the router?  If something changed, a wireless connection might fail.

Is your computer getting an IP address from the router via DHCP?  Has your IP changed as in maybe you accidentally changed the router's address and DHCP range.

Are you normally addressing the router by IP or by name?

My ASUS RT-N16 running DD-WRT router has been working great since April. I made two changes this morning and then rebooted the router. It did not come back. The web page will not load, and I cannot even ping the router (no route to host). The changes were:

1. Enabled USB support for an external hard drive
2. Enabled SSHd with a public key

I have rebooted the router in the past (ie before I made these changes) and the router always came back.

I then removed power from the router for a minute and reconnected power, and it still does not respond to pings or web page access. I also tried connecting the USB drive, thinking it might need the drive to mount, and still no joy.

Short of wiping out all my settings, is there a way to get back into the router and remove these changes? And how do I find out the cause of the problem?

Thanks,

Mark
