We are living in a digital world where internet plays a crucial role for work, study, and entertainment. A stable WiFi connection ensures an enjoyable surfing experience but so many people are suffering from a diversity of WiFi issues from weak signal to long-time buffering without knowing the real cause.
Don't let those WiFi connection issues ruin your daily life and make everyday tasks frustrating. This article will guide you to explore the reasons of why your wireless network is so slow and list all possible ways of how to boost WiFi speed on PC and laptop.

Understand the Basics of WiFi
What Is WiFi
WiFi, the wireless networking technology, makes it a reality to connect your devices (PCs, laptops, mobiles and smart TVs) with the internet without cables. It transmits data between wireless router and internet interface card of your device through radio frequency waves across different bands:
2.4 GHz – Offers wider coverage but slower speeds and more interference.
5 GHz – Provides faster speeds and lower interference but shorter range.
6 GHz - Delivers massive bandwidth and almost zero legacy interference, the newest frontier.

How Does WiFi Work
WiFi uses a set of standards (technically IEE 802.11 protocols) to implement WLAN connection. Each standard comes with different frequency bands, maximum data rate, channel and modulation techniques. WiFi 7 is the latest standard that operates across 2.4/5/6 GHz bands, ensuring optimized performance.
What Are Types of WiFi
WLAN - Local Area Network: Commonly used in home or office that covers a localized building.
WAPN - Personal Area Network: Short-range network designed to connect a minimal number of devices within a small area.
WWAN - Wide Area Network: Utilizes cellular data to provide continuous internet access across geographic areas.
Top Factors to Affect WiFi Speed
As more devices support WiFi connection for high convenience, slow WiFi is reported as a common issue. How to increase WiFi speed? Before making any change, it is a necessity to diagnose why your WiFi speeds are tanking. Check the main reasons that slow down the connection.
Physical Router Distance
The farther your device is from the router, the weaker the WiFi signal becomes. Worse yet, materials like concrete, brick, metal lath, and even large mirrors, can reduce signal strength.
Network Interference
A crowded neighborhood with dozens of routers/wireless devices probably cause network congestion and interference. Also, bandwidth gets divided internet speeds gets slower if too many device are connected with the same network at the same time.
Weak Hardware
An older wireless router/network card may not support modern WiFi standards or high-speed plans, leading to a limited performance.
Outdated WiFi Driver
Your software won’t be able to process the incoming data efficiently with outdated or corrupted wireless network drivers. Slow internet speed and random disconnection may happen unexpectedly.
Bandwidth-Consuming Software
Sometimes, your network works well but background processes like Windows update, cloud syncing, large downloads, etc., silently eat your bandwidth, leaving other things stuttering.
How to Boost WiFi Speed on Windows
If you are struggling with slow wireless network and need a way to improve its performance for better productivity, troubleshooting tips blow can help you get faster speed on PC and laptop.
1. Put Your Router in a Better Place
It is a practical method to enhance your WiFi signal by moving your router as close as possible to your PC/laptop. If you have several connected devices in a room or office, put your router in a central, open and higher location for better signal coverage. Avoid placing it in corners or behind walls.
2. Restart Your Router and Modem
Glitches appear when your router and modem have worked for a long time, like long loading time, buffering videos and more. A simple reboot can clear temporary network issues and refresh the connection.
Turn off your router/modem for about 30 seconds.
Turn on your router and modem again.
Restart your device and reconnect WiFi.
3. Swift to 5 GHz or 6 GHz Band
If your router supports dual-band or tri-band, make sure your PC or laptop is explicitly connected to the 5 GHz or 6 GHz network rather than the default 2.4 GHz option.
Click your Wi-Fi icon in the taskbar. Look for your network name with "_5G" appended to it, or check your router settings to ensure the bands have distinct names so you can choose the faster one manually.
4. Reduce Wireless Interference
Some household appliances like microwaves, bluetooth devices, security cameras, etc., commonly operate the same wireless frequency and cause localized interference. Please put your router away from those objects.
5. Optimize Your Router
Adjust router antennas: Router antennas are used to shape, direct and maximize your WiFi signal. Most antennas are are omnidirectional and broadcast a "donut" of energy perpendicular to the antenna itself. Adjusting them ensures coverage reaches exactly where you need it most.
Update router firmware: Up-to-date firmware can protect your network against cyber threats, fix bugs, improve WiFi speed and compatibility with newer devices. Visit the manufactures websites, download the latest version and update.

6. Limit Background Network Usage
When you find the WiFi speed slow down all of a sudden, check whether there are some background processes that heavily consume bandwidth. Stop unnecessary processes like large downloads, cloud backup, auto-update, to boost WiFi speed for active tasks.
Tip: You can use a third-party PC optimizer to monitor your PC status in real-time and close unnecessary apps automatically.
7. Update Your WiFi Driver
WiFi driver update ensures improved performance, stability and better compatibility with new network adapter.
Go to Device Manager > Network adapters > right-click your WiFi adapter and update driver.
8. Keep Your Network Safe
Malware or unwanted software may use internet bandwidth in the background. Running a trusted antivirus scan can help improve network performance and get WiFi faster.
9. Upgrade Hardware
Modern WiFi standards (WiFi 6/6E/7) ensures faster WiFi and low latency. Get a new router or network adapter that supports newer standard can help you boost internet speed on PC and laptop.
10. Additional Tips to Boost WiFi Speed
There are some more tricks that possibly enhance your WiFi connection.
Use a WiFi extender or mesh system for larger homes or offices.
Use strong router security to prevent unauthorized access.
Disconnect used devices from the network.
Connect your PC/laptop with the router using an Ethernet cable if possible.
