File transfer from my wired desktop is very fast and the file is fine. I checked my download speed on the wireless laptop from the internet and get 36 down and 6 up. That’s what our plan provides. That should prove that my network is ok wouldn’t you think? Transferring files from laptop to desktop works fine through shared folders. Will have to try RD Works and see how that manages. This is a home network with no kids around, not a lot happening on the network.
