Disabling Unneeded Protocols
3. Type netsh interface tcp set global autotuninglevel=<level> and hit
Enter. Replace <level> with either highlyrestricted, restricted, normal, or
disable.
For example, a complete command would look like netsh interface tcp
set global autotuninglevel=disable .
I find it best to experiment with all the different levels to see which one works
best in your environment. If you want to revert back to the default settings, set
autotuninglevel=normal .
Disabling Unneeded Protocols
Every computer comes with programs installed that you do not need. As with
extra programs taking up space, extra protocols are just wasting your network
connection and can actually slow it down. How is this possible? By default, a
few different protocols are installed on your computer to allow for maximum
compatibility with other computers on a network; these protocols each require
bandwidth to operate. Most users don’t use many protocols, and their computers
use up a portion of their connection as they respond and transmit information
for these protocols.
Additionally, with extra protocols installed on your network adapter connected
to the Internet, you increase the risk of having security-related problems. One of
the most common risks for broadband users is having the Client for Microsoft
Networks networking protocol enabled on their connections and no firewall
to block the public from their computers. This protocol allows everyone on the
users’ networks, or local neighborhoods if they have a cable connection without a
firewall or router, to connect to their computers and view any files that they may
be sharing. This fact alone should be a good enough reason for you to turn off
the extra protocols, but with them disabled, you save a little bandwidth as well.
Viewing Protocols on Your Network Adapters
Viewing the protocols installed and active on your various network adapters
is easy. Just follow these quick steps and you will be viewing them in no time:
1. Open the Start screen, type Network and Sharing Center , change the
filter to Settings, and hit Enter.
2. On the side menu, click Change Adapter Settings.
This shows a list of all the network adapters installed on your computer.
3. Right-click any of the adapters and select Properties.
