Solution 4: Disable Large Send Offload (LSO)

Another way to fix slow file transfer speed between two computers on a LAN is to disable the Large Send Offload (LSO) feature, following these steps!

Step 1: Press the “Windows + X” keys and select “Device Manager” from the drop-down menu.

Step 2. Next, double-click on “Network adapters,” and then click the “Advanced” tab.

Double-click on the Network Adapter icon.

Step 3. Here, select "Large Send Offload v2 (IPv4)" and set the value to "Disabled."
