Hi Frank.
I'm suspecting your network or your network adapter or the driver you use.
Can you try to transfer big file (>10Mo) between your file server and
your centos ?
Using another protocol like : ftp, sftp, scp, http ?
Can you connect your centos on a different network plug, using a
different cable ?
Can you install an other network adapter ?
