I have two computers both Windows 7 Pro. Computer 1 can transfer to WHS and Computer 2, WHS can transfer to Computer 1 and Computer 2, Computer 2 Can transfer to Computer 1 but when trying to copy files to WHS it will go at about 60KB/s for a few moments
then give an error "There is a problem accessing \\WHS\Folder Make sure you are connected to the network and try again."
All of the other transfers are at a minimum of 20MB/s between all of the computers. I have tried copying files as large as 19GB and as small as 4MB all with the same problem.
Computer 2 is a laptop and has a Realtek PCIe NIC and an Intel Wireless card. I tried the realtek NIC drivers from microsoft and from realteks website both have the same problem. When I switched to wireless the transfer will go through.
