there are two settings of the network card that may cause problems with transfers. Both have to do with offloading tasks from the operating system to the network card, but sometimes the handshake between the two fails.
Disable Large Send Offload
Right-click the Network Adapter in Network Connections and then click Properties.
Click the Configure button and then the General or Advanced tab.
Set the “Large Send Offload” parameter to Disable.
Disable Checksum Offloading > this can be disabled under the NIC properties also , but if you feel nerdy the registy fix is
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
In the right pane, make sure that the DisableTaskOffload registry entry exists. If this entry does not exist, follow these steps to add the entry:
1. On the Edit menu, point to New, and then click DWORD Value.
2. Type DisableTaskOffload, and then press ENTER.
On the Edit menu, click Modify.
Type 1 in the Value data box, and then press ENTER.
Exit Registry Editor.
