Hi, I am Sam.

I curate and write tech news and articles.

As a professional writer, I have the privilege of writing about emerging technologies and the way they will shape the world in the coming years. I cover a broad range of topics, from new software and hardware to artificial intelligence and augmented reality.

I spend a great deal of my free time reading about and trying out new tech, so it's hard not to do it for a living. I have a knack for finding the most relevant and important stories, and I easily get them to the top of large news outlets' lists.

How to Make Your PC Run Faster

Picture yourself working on a critical project, when all of a sudden everything slows down to a crawl. Unfortunately, this is a familiar experience for many Windows users. However, there are several things you can do to speed up your computer. This article will show you how to make essential tweaks that can lead to a significant performance increase.

1. Make sure your computer isn't infected with viruses.

Computer viruses are extremely dangerous, causing a lot of damage to your computer. Some malware species can encrypt or delete your files without warning, for example. Viruses will also slow down your computer, reducing its speed drastically. So, use a third-party antivirus, such as Panda's Cloud Cleaner, to check for potential issues.

2. Reduce the number of applications that run at startup.

Windows has a lot of applications and services that run automatically when you start your computer. While some of them are needed, other software packages are used by software developers to collect diagnostics data, etc. and will slow down your computer.

Fortunately, Microsoft has made it easy to get rid of unwanted startup applications. Fire up Task Manager by pressing Ctrl + Shift + Esc, select the "Startup" tab at the top of the window, choose the apps or services that need to be disabled (one at a time) and then validate your choice by clicking the button at the bottom of the screen.

Effective Ways to Boost Wi-Fi Signal

These days we depend on Wi-Fi networks more than ever. We use them for work-related purposes, to browse the web looking for exciting news, we check our email accounts, stream movies, watch sports games, listen to music, and do lots of other important, interesting, or entertaining things. According to this statistic, the number of public Wi-Fi hotspots worldwide has reached 550 million. Not all of them are properly set up and configured, of course. Here are some of the most effective things you can do to increase wireless signal strength.

The router is the heart of any home network. It transmits all the data that flows through your Wi-Fi, and it can’t do that if it’s not in the right place. A common mistake people make is placing the router near metallic appliances such as washing machines or refrigerators. This reduces the amplitude of the Wi-Fi signal, causing problems.

Installing the router near other electronic devices such as television sets, microwaves, cordless phones, or active speakers can cause similar problems due to interference. So, it is best to avoid all these devices when looking for a good place for your router.

Wi-Fi signal strength can be estimated by taking into account two essential aspects: the distance from the router to the device, and the actual speed of the wireless connection. Fortunately, if your router uses regular RP-SMA connectors, you can replace the stock antennas with better ones without opening the router case. More info about RP-SMA can be found here.

Many router manufacturers use low-end antennas, which have a gain of 4-5 dBi. If you purchase a set of 10 dBi antennas, for example, you will double the Wi-Fi signal power. The new antennas may be taller than the old ones, but that's a small price to pay in comparison with the benefits that arise from having a reliable Wi-Fi network.
