You might need to set a dip switch to set it on by default. If the device is scsi check to see if disconnect is enabled on the controller by default. I have a WangDAT 3400DX device on a BT946c/p90 and it screams. It seems to be able to sustain about 19-20 mb per minute while the system is also running a full newsfeed and multi-homed web sites. I've been very impressed by the 3400DX performance and reliability. Regards, Mark Hittinger Internet Manager WinNET Communications, Inc. bugs@win.net
