I'm in need of directions on how to update the firmware for these devices. (WM3400) I downloaded the 184.108.40.206-007R and 220.127.116.11-018R. I created a FTP here at my office and it appears to work fine when I use the online testing tools. However when I attempt to use the WM3400 FTP option it never seems to even reach my FTP server. I've opened up our firewall and still can't seem to get the FTP to work.
I also tried the USB option which tells me that I can't mount the USB or gives me this error code.
