How to increase LAN speed between computers
Well, we all like speed in some or the other way right? This article should be easy enough should you have a small home or small office network and you need to transfer some files between computers. There are other ways on search engines and some voiceless instructional videos where you need to perform some commands as well (which might or might not have an effect on above mentioned title).
Before I go on, I must credit the original author of this instructional (ugetfix.com) for making this tutorial possible (and some of my own know-how).
Just some prerequisites:
- Make sure you have the latest updates for Windows installed (security and major updates)
- Make sure you don’t have viruses on your computers, because this will just complicate your life in a lot of ways (keep away from the dodgy P2P sites as well as some “alone time” sites).
- Make sure your network interface card(s) drivers are up to date.
- If you know something about firewalls, make sure that the rest of this article won’t have an effect on your setup (which I highly doubt).
Disable Large send offload feature
- Right-click on the start menu, and select “Device Manager“.
- Look for “Network Adapters” and expand the selection.
- You will need to find your LAN device (where brand names might differ), right-click on it, and select “Properties“.
- Now click the “Advanced” tab and select (on the left pane window) and select: Large Send Offload V2 (IPv4)
- If you make use of IPv6, do the same there as well.
- Under “Value“, select “Disabled“.
- Don’t Close the Advanced Network Window.
Alter duplex settings
- If you have closed the Network Window, close all the open windows, and repeat steps 1-3
- Now Select the Advanced Tab.
- Find Speed/Duplex settings under Property, and select “1.0 Gbps full Duplex“
You probably know the obvious, “Apply”, “OK”, and restart your computer(s) thing.
The computers you have done all this, should transfer data more quickly between them.
I feel I must add the following notes:
- The obvious thing is, that you need to have a fast as possible network switch (Gigabit preferably)
- Then you need to have Gigabit Network cards in all of your computers
- Factors like CAT5 and CAT6 cabling might have an effect on performance
- Computer performance itself will also have an impact – if you copy from an SSD to a normal HDD, you will also only get that much speed.
- This tutorial might work for some people, and others might have more complex setups and environments where other factors play a role.
