So when at password and you type in 12345678 your saying nothing happens.
I am assuming that you have are trying to upload the latest software from a newly prepared SD card and not trying to access your original version as set up with Peter's assistance. If it is the latter that you are trying to do then your password will be the one you set up with Peter, your station name plus the number 1. all in lower case letters.
sorry Eric , I didn't see your edit until after I posted. No I don't know how to log into your system, there are things you would have to do to the router to allow someone to do that and I've been looking at your router specs and not sure if it can be done.
