This is the network setup I have:

1. I have a 100 Mbps fiber optic Internet line
2. I have a wifi router. 1 ethernet port is connected to a Rasperry Pi and another one is to Netgear WNDR3700 (which gives speeds of up to 300 Mbps) connected with a wired ethernet cable 30 meters away.
3. I have set it up as a bridge, so in that way, when I connect my Mac to the Netgear I have access also to the Rasperry Pi

Now, when I try to copy a file the speed transfers are VERY slow... 

1. I have a hard-drive attached to the Raspberry, and I have shared it with Samba
2. I have also tried doing an scp from my Mac to the Rasperry:

`scp test.avi root@192.168.1.42:/media/maxtor/Movies test.avi 89% 4005MB 918.7KB/s 08:45 ETA`

The speeds rates I get are VERY slow (below 1 Mb/s).. In fact, I get faster speeds in downloading a file over the Internet on Wifi, than having a wired file transfer between my Mac and my Rasperry.

Any ideas what I may be doing wrong?

(P.D. my networking knowledge/systems is very limited, so i may have used wrong terminology).
