Well I'm a novice in these matters, but I've finally managed to install Toastman firmware on my Neatgear WNR3500L. I've hooked it up with a 1TB harddrive and can access it from OS X. It is incorrectly named "unknown" in network, but I can see all the files and also read them. However, I cannot write to the drive at all. I'm asked to enter name and password, but get permission denied in return.
What am I doing wrong?
