5 Tips To Improve Your Internet Connection

imageThe web is packed with tools which claim they’re the best choice to accelerate your Internet connection.Most of them promise too much and deliver nothing at all, though, so installing another probably isn’t high on your list of priorities.The speed of your network is determined by three key factors, the speed of your equipment, Internet connection, and network configuration.  Your  network equipment is made up the NIC (e.g. the network port) on the computer, the router/switch, and the cabling you use to hook it together.  If you’re using wireless, there are different factors for this technology.  The Internet connection is only as good as the provider you’re using.  While your system’s network configuration is entirely up to you. here are so many hidden features within Windows  that can actually boost your internet speed.

1.  Avoid DNS Bottlenecks:

Recently, I have seen several instances of organizations virtualizing their DNS servers and placing them on host machines that have little capacity remaining. The basic thought behind this is that DNS does not require many system resources, so DNS server placement can be treated almost as an afterthought.

However, your DNS server’s performance has a major impact on the amount of time it takes for users to access Web pages. So it’s important to make sure that your DNS server has sufficient resources to prevent it from becoming a bottleneck.For those that don’t, DNS is a network service that converts a domain names (e.g. example.com) into an IP address (e.g. 192.0.43.10).  Its a critical network service that makes navigating the Internet easier for humans.  For example, lets say you had to typehttp://74.125.127.147/ instead of http://www.google.com/ to utilize this site.

2. Use DNS Forwarders:

The idea behind a forwarder is that if your DNS server is unable to resolve a query, it sends the query to a forwarding address to be resolved by an external DNS server.It’s common to point the forwarder to the DNS servers that are owned by a company’s ISP. The problem is that these DNS servers can be located anywhere. For example, my ISP resides in South Carolina, but it uses a DNS server in France. If you really want to optimize your Internet connectivity, your DNS forwarder should point to a DNS server that is in close physical proximity to your geographic location.

If you aren’t sure where your ISP’s DNS servers are, I recommend using one of the visual trace route applications to determine where the DNS servers reside. The Visual Trace Route Tool  is one free option.If you do determine that you’re forwarding DNS requests to servers that are far away, the forwarder should be redirected to a DNS server that is in closer geographic proximity. If you don’t know of another DNS server you can use, try checking out OpenDNS.

3.  Use A Proxy Cache:

When a user enters a Web URL, the request is sent to the proxy server, which then issues the request on behalf of the user (similar to the way a NAT device works). When the proxy server receives the requested content, it forwards it to the user, but it also stores a copy for itself. If a another user requests the same content, the proxy server can deliver it without having to send the user’s request to a Web site. Cached content is delivered almost instantly, so the result is lightning-fast Internet access for your users (at least for any content that has been cached) and decreased Internet bandwidth usage.

4.  Secure Your Wireless Access Point:

This actually lets you optimize various settings and registry to make your net connection much faster. Internet connection by securing your wireless access points. I realize that this sounds ridiculous to anyone who is managing an enterprise class network, because all your access points should already be secure. But a tremendous number of small and midsize businesses are operating unsecured wireless access points.

From an Internet optimization standpoint, the problem with unsecured wireless access points is that they allow an Internet connection to be used by anyone. A neighbour could potentially be consuming the majority of the available bandwidth.Internet connection by securing your wireless access points. I realize that this sounds ridiculous to anyone who is managing an enterprise class network, because all your access points should already be secure. But a tremendous number of small and midsize businesses are operating unsecured wireless access points.The good news is that you may already have everything that you need to set up a proxy server. Microsoft’s Forefront TMG can easily be configured to act as a proxy cache.

5.  Block Streaming Media Sites:

As you might already know, there are a small collection of streaming media protocols in common use today. These include:

* MMS
* RTSP
* PMN
* HTTP

At first look it might appear to be easy to block streaming media protocols. Just don’t create any rules that allow them. That’s easy to do for MMS, RTSP and PMN, but its not so easy for HTTP. Obviously, you can’t block HTTP, so we have to consider alternate methods to block streaming media moving over an HTTP application layer transport (note that HTTP is not a transport protocol, but we often refer to the application level protocol that carries the data as an application ”transport”).

There are a few options for controlling streaming media moving over the HTTP trasport. These include:

* Using the HTTP Security Filter to block headers used by the streaming media application
* Blocking connections to known streaming media sites
* Avoiding allow rules for streaming media sites. That is to say, you create allow rules for sites users are allowed to visit, and all other sites are denied
* Blocking the streaming media application using the Firewall client settings
* Blocking the Content Types used by streaming media applications
