Wondering how to make your internet faster on your PC? Maximizing your Internet speed is a crucial step in the quest for a faster computing experience, and one of ever increasing importance because just about all we do with our machines nowadays we do while connected to the web. Follow our easy guide to boost your internet speed, and learn how iolo’s System Mechanic internet features can help make your wifi faster on pc.

1. Clear Your Browser Cache

Your web browser can accumulate temporary files, cookies and cached data overtime, which can slow down internet speeds. Clearing out your browser cache on a regular basis can help to remove unnecessary data, which can help to boost internet speed.

2. Update Your Windows Operating System

When Windows software is outdated, it can lead to compatibility and performance issues. Ensuring that your Windows operating system is up to date, can help to optimize system performance and speed up internet connection.

3. Manage Background Applications

If you find that the internet on you windows laptop or computer is slow, but fine on another device, this may be due to background programs consuming valuable bandwidth. These can include software updates, cloud syncing, or malware. Managing your background applications, and disabling unnecessary programs can help to free up internet resources and increase internet speed. This can be done in Windows’ Task Manager, which is accessible by right-clicking on your task bar, or pressing Ctrl+Alt+Delete.

4. Optimize Network Settings

By changing your network settings, you can easily speed up your internet. System Mechanic’s internet tools, enable you to see whether your internet connection settings optimized for boosting download speeds and high performance online.

5. Use iolo’s NetBooster

To help satisfy your ongoing need for better broadband, System Mechanic’s internet optimization feature, NetBooster® , has been re-architected with a whole new set of TCP/IP optimization tests and network setting modifications specifically for Windows versions all the way through Windows 10.

Improving Windows settings

In addition to outward-reaching solutions to Internet speed optimization, breakthrough iolo Labs research has unearthed a whole cache of underperforming Windows Internet settings within your computer, and they too are crying out for optimization.

Regardless of how new your OS may be, when these hidden settings are adjusted correctly, the difference in your Internet experience can be significant. Recent benchmark tests comparing NetBooster’s adjustments to the default settings show boosts in download speed by an average of 23%, and by as much as 37%.* Let’s look in detail at what two of the most critical of these settings can do.

Adjusting data packet size


Data is transmitted across the Internet in packets. One way to increase the efficiency of this process is to discover the largest possible size (in bytes) a data packet can be for a given network before it has to be broken up to transmit. This value, often determined by your router, is called the Maximum Transmission Unit (MTU). NetBooster automatically discovers this value, takes the MTU setting in Windows out of “autotune” mode, and fine tunes it, helping to eliminate data fragmentation at routers and so reducing network congestion.

Rethinking Nagle’s algorithm to reduce latency

An engineer named John Nagle invented a way of increasing TCP/IP network efficiency by reducing the overall number of packets that need to be sent over a network. It works by coupling very small data packets together, but often at the expense of real-time responsiveness because the algorithm delays in sending small outgoing messages until they collectively reach the desired amount of bytes to make them “worth” sending. Some networked multiplayer video games can suffer from Nagle’s algorithm because these programs assume gaming actions are sent immediately, not in delayed coupled packets. Therefore, disabling the algorithm can help eliminate the stuttering time delays in gaming known as latency.
The impact of disabling Nagle’s algorithm (or De-Nagling) was examined by iolo Labs with World of Warcraft as the test scenario. Both in-game latency reports and a Wireshark packet analyzer were used, and the end results showed on average a 20% reduction in game delay.**

De-Nagling improves TCP-bound, networked games like World of Warcraft, Guild Wars 2, Eve Online, and Flash-based games such as League of Legends. NetBooster lets you control when and if you decide to De-Nagle, as disabling Nagle’s algorithm may negatively impact large file transfers in a very high latency network.

Optimize automatically or manually
No less than 14 total settings within Windows TCP Global Parameters can and should be adjusted from their default settings to best handle network traffic on your particular system. NetBooster automatically sets each of these to their optimal values.

Alternately, by choosing “Customize Advanced Internet Settings”you can manually adjust each value yourself. Within this interface, the “Restore All to Orig” button allows you to easily revert to NetBooster’s original configuration if after tweaking the settings you experience problems with the network. In future articles and tips, we’ll walk through several of the features advanced users can access in NetBooster’s manual mode to finely adjust Internet settings to meet their specific network needs.

Instead of putting up with the bitter indignity of an underperforming Internet stream, System Mechanic users can deploy NetBooster to help gain significant, welcome increases in Internet speeds, resulting in improved bit rate and picture quality of TCP-bound videos and games, less time in the dreaded “Buffer Zone,” faster downloads, snappier page loads, and an increased rate of large file transfer.

Let ActiveCare® handle it

System Mechanic automates a series of maintenance actions while your PC is idle. This process is called ActiveCare and it not only ferrets out clutter and obsolete files and programs, but it will automatically optimize your Internet settings if NetBooster is enabled. To be sure that it is:

  1. Open System Mechanic.
  2. Navigate to the “Performance” section.
  3. Click on “ActiveCare”.
  4. Toggle the switch to “On” to enable ActiveCare for regular computer scans.
  5. Optionally, click on “Run Scan” to initiate a scan of your computer.
  6. Review the scan results.
  7. Click on “Fix Issues” to address any identified issues and optimize your system’s performance.
