RT-AC66U - Admin Console

Hi there guys,

Yesterday, I updated the f/w of my RT-AC66U to 3.0.0.4.378.9313.

Now, when I http://192.168.1.1/ into the admin section, its asking me to sign in. I am using the same auto details, but it wont let me go any further, only an error message of * Invalid username or password.

Any help would be great.

Thanks.
