I have thre computers with Gigabit Network adapters built in. There is an Internet connection with only a 10/100 router which I cannot change. They all connect to the Internet router through a new Gigabit switch. (I call it NETWORK A)
Internet connection speeds of all computers are as fast as they should be. However, I need to transfer shared files between the computers but cannot transfer at more than 10/100 speeds. If I disconnect the Internet router connection, speeds between computers move at Gigabit speeds. Reconnect theInternet connection and inter computer speeds goes down again.
I installed a second Gigabit card in each, and connected these through a separate Gigabit switch. (on a different subnet, of course, and there is no Internet connectivity on this network, I call it NETWORK B) But traffic between the computers will not flow over network B unless the original path (NETWORK A) is disconnected in at least one of the computers attempting a transfer. When that happens, speed through the second network moves at expected Gigabit speeds.
I have gone into the networking adjustments in Windows 7 and set the NETWORK A as the first connection priority. But no matter what, file transfers do not go through this network as long as NETWORK A is present.
Any assitance would be welcome. I am using Simple File Sharing, Windows 7, on a Workgroup. (Not Homegroup)
Thanks,
