On my local network my upload rate to my WHS is only around 150 kbs where as I can download at about 20 mbps. Also, I hooked up another computer on the same network in the same way and it is able to upload around 20 mbps also.
I already reset my router, restarted both computers, and reinstalled the WHS software on this computer but I am still having problems. Any suggestions?
You might try updating the NIC driver on the client that is experiencing the network slowdown.
