Slow file xfer over 100Mbps link

Hi Experts,

I'm having issues determining what's causing slow transfer speeds between a server and all workstations located in the same remote office.  The remote office and main office are connected via 11Mbps wireless link, all under 1 domain.  However, the files I'm trying to copy are located at the remote office server (just a member server), using a workstation at that remote office as well.

We have CAD files at around 100MB in size, and it takes ~2-3 minutes for the the workstation and server at the remote site to copy files to each other.  We have a 100Mbps Nortel switch that these computers link at.  This just doesn't seem right?!?!?!?  Theoretically @ 100Mbps link speed, it should be 12.5MB per second xfer rate (100,000mbps/8 = 12,500 = 12.5MB/sec).  It should be more like 8-10 seconds.

In the meantime I've turned the remote server into a primary dns server, and pointing the workstations to that server.  Tried it again, and same result.

Here's some detail what my client grabs through TCP/IP...All DHCP is coming from the main site over the 11Mbps wireless

IP (DHCP):  172.25.5.100
S/N Mask (DHCP):  255.255.0.0
Gateway (DHCP):  172.25.0.10
DNS (Static):  172.25.1.70 (remote server address)

I even tried all static, but still the same issue.  I thought if I turned the remote site into a dns server, this would be resolved, but apparently not.  I still suspect it has something to do with the wireless, but it doesn't make sense if I'm pointing DNS to that remote-site server from a remote-site workstation.

Any ideas what I'm doing wrong?
