Why is the transfer speed slow between computers on a local area network?

The issue of slow file transfer speed between two computers on a local area network (LAN) can be caused by several factors, including:

• Router configuration or hardware failure
• Antivirus software
• Enabled LSO feature
• VPN applications
• Proxy servers
• Outdated drivers and system software

One of the reasons mentioned above could be slowing down the file transfer speed between two computers on a LAN. So, to enjoy a smooth transfer speed, always avoid all these reasons and fix them as mentioned!

How to Resolve Slow LAN File Transfer Speed in Windows

Now that you know the possible reasons for slow file transfer speeds between two computers on a LAN, it's time to fix the issue using any of the four methods below!

So, let's take a closer look at each way to fix slow file transfer speeds on your Windows PC!

Solution 1: Turn off “Remote differential compression”

Remote Differential Compression (RDC) might slow down file transfers between two computers on a local network. To resolve this issue, you need to turn off RDC by following these steps:

Step 1: Press the "Windows key + S" simultaneously, and then type "Windows Features" in the search bar below.

Step 2: Here, click on “Turn Windows features on or off.”

Step 3: Locate and uncheck “Enable compression for network bandwidth optimization,” then click OK.

Step 4. Finally, restart your computer. Make sure you do this for all computers on your network. After that, check if the problem still persists.

Solution 2: Disable TCP Auto-Tuning for faster transfers

If the above solutions do not work, try fixing it by disabling the “TCP Auto-Tuning” feature!

When copying files over the network, autotuning can improve the performance of programs receiving TCP data over the network. However, in some cases, disabling it can increase file transfer speeds.

Here's how to disable the "TCP Auto-Tuning" feature on your Windows PC:

Step 1: Press the "Windows + X" keys at the same time, and then choose "Command Prompt (Admin)."

Step 2. Type netsh int tcp set global autotuninglevel=disabled, and then press Enter.

Step 3: Try transferring all your files and see how fast it goes.

Note: You can open Command Prompt (Admin) again and enter netsh int tcp set global autotuninglevel=normal, and then press Enter to re-enable Autotuning.

Solution 3: Disable Large Send Offload (LSO)

Another way to fix slow file transfer 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 at the same time, and then select “Device Manager” from the drop-down list.

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

Double-click on Network Adapters.

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

Step 4. Repeat these steps for Large Send Offload v2 (IPv6), and then click OK.

And that's it! You have successfully disabled LSO on your Windows computer.
