How to Increase WiFi Speed?

How to Increase WiFi Speed

WiFi allows us to access the internet wirelessly. However, slow WiFi can negatively impact our ability to work, learn, and be entertained. Fortunately, there are various ways you can optimise your WiFi network to increase speed and performance.

How to Increase WiFi Speed?

Check Your Internet Speed

The first step is to check your current internet download and upload speeds. This will establish a baseline to compare future optimization efforts against. Do a speed test during both peak and non-peak usage hours to get a reliable benchmark.


Optimise Router Location

WiFi routers need open spaces and fewer obstructions to broadcast strong signals. Place your router:


Near the centre of your home or office for widest dispersal

On an upper floor or in an elevated central area

Away from potential sources of interference like microwaves, baby monitors, Bluetooth devices, and cordless phones

Avoid putting inside enclosed cabinets, behind furniture, or near exterior walls

Also, make sure the router antennas are parallel and pointing upward rather than inward.


Update Router Firmware

Router vendors regularly release updated firmware that improves WiFi performance by:


Enhancing wireless signal strength

Boosting speed and range

Fixing bugs and security flaws

So check the manufacturer’s website to get the latest firmware for your router model. Then login to the router admin interface and update if needed. This keeps the router operating optimally.


Change Broadcast Channel

In densely populated areas with many WiFi networks, changing the broadcast channel that your router transmits on can improve performance.


Log in to your router settings

Locate the basic wireless settings

Change the channel from Auto to either 1, 6, or 11

Save settings and test if internet speeds increase

This prevents channel conflicts and interference with neighbouring WiFi networks.


Adjust Router Antenna Directionality

If using a multi-antenna router optimally positioning the antennas can concentrate wireless signals for stronger directionality:


Point one antenna vertically towards WiFi devices located above

Aim other antennas laterally in the direction of areas where devices mostly connect from

Experiment to determine the best antenna positions and directions

Use 5Ghz Network Band

The 5Ghz WiFi band transmits faster speeds with less interference than 2.4Ghz networks. Connect devices using 5Ghz for better performance:


Dual-band routers broadcast both 2.4Ghz and 5Ghz networks

5Ghz provides faster short range connectivity best for video and gaming

2.4Ghz has slower speeds but longer range through walls over greater distances

When in range, prioritize 5Ghz for bandwidth-intensive tasks.


Change WiFi Mode to 802.11ac

802.11ac is the latest WiFi transmission protocol with fast wireless networking. If your router is 802.11ac compatible switch WiFi mode to enable the speed benefits:


Access router admin interface

Go to wireless settings

Set mode to 802.11ac from auto/mixed modes

Save settings

This establishes 802.11ac WiFi connectivity for newer devices that also support it.


Adjust Transmission Power

Increasing router WiFi transmission (TX) power can enhance signal strength for better speeds at longer distances.


Find current TX power level in admin interface wireless settings

If set to 50%, increase to 70% or 100%

Save changes and test if internet speeds improve in remote areas

However, take care not exceed 100% as it may degrade performance.


Enable Quality of Service

Quality of Service (QoS) gives important network traffic like video conferencing and streaming higher priority. This prevents bandwidth contention with normal traffic:


Log in to router admin interface

Locate QoS settings

Enable and assign priority to essential applications and devices

Save changes

Giving priority traffic preferential treatment reduces latency and lag for better speed.


Assign Static IP Addresses

Dynamic IP addresses assigned by DHCP can change causing devices to briefly lose connectivity:


Log in to router admin interface

Find DHCP settings

Assign permanent static IP addresses to frequently used devices

This maintains persistent IP address access

Static IPs prevent changes that can impair speeds.


Upgrade Internet Bandwidth

If your available internet bandwidth is consistently maxed out it will throttle WiFi speeds. Upgrading internet download/upload speeds solves the bottleneck:


Contact internet service provider

Check if faster bandwidth packages are available

Upgrade to higher bandwidth

This lifts the ceiling on possible WiFi transmission rates

Faster internet means faster WiFi!


Verify Modem Capabilities

Older modems may not support the latest internet speeds offered by ISPs. Check your modem specifications to ensure compatibility:


Login to modem admin interface

Review model specifications

Check max download/upload speed capabilities

If required upgrade modem

This prevents modem restrictions on WiFi speeds

Switch to Mesh Network

Mesh networks have multiple access points working together to blanket large areas with strong WiFi coverage. Benefits:


One WiFi network – Devices automatically switch between access points

Eliminates dead zones

Dedicated backhaul – Separate data connection between nodes to avoid congestion

Self-optimising – Nodes auto adjust channels/power for optimal performance

One seamless high-speed network!


Test Bitrates Between Devices

Wireless bitrate indicates data transfer rate. Test bitrates to detect poorly performing devices dragging down WiFi speeds:


Connect to WiFi router admin interface

Check wireless settings for connected device list

Note bitrate for each device

Low bitrates indicate outdated devices unable to cope with demands

Upgrade or remove poor performers.


Disable WiFi on Idle Devices

Laptops, phones, tablets with WiFi left on when idle can congested networks. Turn off WiFi when not in active use:


Windows – Disable WiFi adapter

Mac – Turn off in menu bar

iOS – Disable from Control Center

Android – Turn off in notifications drawer

This reduces non-essential background WiFi traffic.


Position WiFi Extender Properly

WiFi extenders rebroadcast signals from the router to expand coverage. But improper placement can degrade performance:


Position within signal range of router

Near centre between router and weak coverage area

Avoid putting near other wireless devices

Experiment to determine optimal extender location

Correct placement maintains backhaul speeds.


Change WiFi Password

With open WiFi networks, unwanted devices could be secretly connected, stealing bandwidth. This can slow speeds:


Set a strong WiFi password using special characters

Enable WPA2/WPA3 encryption on the router

MAC filter to restrict device access if required

This secures the network from moochers

Added security gives more speed for legitimate users.


Key Takeaways:

Check internet speed baselines during peak/non-peak times

Optimize router placement centralised in open elevated areas

Update router firmware, enable QoS, assign static IPs to high-use devices

Switch to 5Ghz band, 802.11ac mode for faster transmission rates

Consider upgrading bandwidth, modem, switching to mesh networks

Test bitrates to identify and upgrade/remove poor devices

Properly place WiFi extenders to maintain backhaul speeds

Secure network to prevent moochers from stealing bandwidth


Achieving faster WiFi networks involves both hardware and settings optimization. Start by checking internet bandwidth caps and modem capabilities. Strategically place the wireless router in an ideal centralised location. Configure settings like WiFi band, mode, transmission power and static IPs for better performance. Considering upgrades to achieve the latest standards for speed. Regularly maintain firmware and test metrics to sustain optimal speeds. Using these tips comprehensively can unlock much faster WiFi!
