Really slow transfer Ethernet -> MBL

My setup is as follow

100Mb ethernet connected to MyNet n600 which has a MBL 3TB connected. When transfering files, the speed is around 150k/s. If i disconnect the Ethernet and use Wifi instead, the transfer spped is 2.2 MB/s (expected)

Why is the ehternet transfer rate so slow?

Refer here (bottom of first page):

I’ve just been through a similar experiance.

Check for older elements on your network. My feeling is that they ‘upset’ the MBL’s a tad. Slow NIC’s, older rated cables, perhaps even obsolete operating systems.
