Doesn't look right. That looks like initial protocol handshake, but not the actual console session.

Use PuTTY or some other proper ssh terminal program.

Kinda hard to believe, considering the process is contained within the WRT AC Series wiki here and here...

Hi, I have the same router as you and I've reverted back to stock firmware plenty of times.
You'd have to SSH into your router, unfortunately, but I find this the easiest way.

  1. I use CMD for this: ssh root@192.168.1.1 then use your password.
  2. cd /tmp
  3. wget http://downloads.linksys.com/downloads/firmware/FW_WRT3200ACM_1.0.6.186168_prod.img
    I use the sysupgrade command to actually revert back. For some reason, this is the only command that works for me.
  4. sysupgrade -F cd/tmp/(name of the firmware).img

The -F forces the update.
