How to Improve Unifi Internet Speed

A fast Unifi connection can still feel slow when your WiFi signal is weak, too many devices are connected, your router is in the wrong place, or the device you are using cannot handle the full speed of your internet plan.

Before assuming there is a problem with your Unifi line, it is important to find out where the slowdown is happening.

Start by running our Unifi Speed Test and check your download speed, upload speed and ping. For a more accurate result, stop downloads and streaming on other devices and, if possible, test once over WiFi and once with an Ethernet cable.

If your connection is slower than expected, the steps below can help you improve your Unifi internet speed.

Quick Ways to Improve Unifi Internet Speed

If you want to troubleshoot quickly, start with these steps:

Restart your router and networking equipment.
Move closer to the WiFi router.
Place the router in an open and central location.
Connect to 5 GHz or 6 GHz WiFi when available.
Use Ethernet for devices that need maximum speed.
Disconnect unnecessary devices.
Stop large downloads and background updates.
Check your Ethernet cable and network adapter.
Update your router firmware when an update is available.
Consider Mesh WiFi for larger homes.
Test your connection on more than one device.
Contact Unifi if slow speeds continue on a wired connection.

Let’s look at each step in more detail.

1. Test Your Unifi Speed First

Before changing your router settings or buying new equipment, find out how your connection is currently performing.

Use our Unifi Speed Test and look at three main results:

Download speed: How quickly data reaches your device. It affects streaming, downloading files, browsing and most everyday internet activities.

Upload speed: How quickly your device sends data to the internet. It matters for video calls, cloud backups, uploading videos and sending large files.

Ping: The time it takes data to travel between your device and a server and return. Lower ping is generally better, especially for gaming and real-time communication.

Run the test two or three times instead of relying on a single result.

If possible, also test at different times of the day.

2. Restart Your Router

Restarting the router is one of the simplest troubleshooting steps and is worth trying before making more complicated changes.

A restart can clear temporary networking problems and allow the router to establish a fresh connection.

To restart your router:

Turn the router off.
Wait around 30 seconds.
Turn it back on.
Allow a few minutes for the internet connection and WiFi to become available again.
Run another speed test.

Avoid repeatedly restarting the router throughout the day. If you need to restart it frequently just to maintain a usable connection, there may be another problem that needs investigation.

3. Put Your WiFi Router in the Right Location

Router placement can make a surprisingly large difference to WiFi performance.

WiFi signals become weaker as they travel through walls, floors, furniture and other obstacles.

For better coverage, place your router:

in a relatively central part of the home;
in an open area;
above floor level;
away from thick concrete walls where possible;
away from large metal objects;
away from enclosed cabinets;
away from equipment that may create wireless interference.

Avoid placing your router in a corner of the house if most of your devices are used on the opposite side.

This is particularly important in larger Malaysian homes, double-storey houses and properties with thick walls, where one router may struggle to provide strong WiFi coverage everywhere.

4. Use the Right WiFi Band

Many modern routers can broadcast more than one WiFi frequency.

The two most common are 2.4 GHz and 5 GHz, while newer equipment may also support 6 GHz.

2.4 GHz

2.4 GHz generally provides:

longer range;
better ability to pass through walls;
lower maximum speeds;
more potential interference.

It can be useful when you are farther away from the router.

5 GHz

5 GHz generally provides:

higher speeds;
lower range than 2.4 GHz;
less congestion in many situations.

If you are near the router and want better performance, 5 GHz is usually the better choice.

6 GHz

Some newer WiFi equipment and compatible devices can also use the 6 GHz band.

It can provide excellent wireless performance in suitable conditions, but both your router and device must support it.

If your speed is good near the router but becomes much slower in another room, the problem may be WiFi coverage rather than your Unifi internet line.

5. Use an Ethernet Cable When Maximum Speed Matters

WiFi is convenient, but a wired Ethernet connection is often more stable and is one of the best ways to determine whether a speed problem comes from your internet connection or your wireless network.

Connect a compatible computer directly to your router using Ethernet and run the speed test again.

If the wired result is much faster than the WiFi result, your Unifi connection may be working correctly and the real issue is likely related to:

WiFi coverage;
router placement;
interference;
WiFi band;
router capability;
or your device’s wireless hardware.

Ethernet is particularly useful for:

desktop computers;
gaming PCs;
game consoles;
smart TVs;
workstations;
large file transfers.

For faster Unifi packages, also make sure the Ethernet port on your device can support the required speed.

A device limited to 100 Mbps Ethernet, for example, cannot measure several hundred Mbps simply because the internet package is faster.

For gigabit and multi-gigabit plans, the capabilities of the router ports, network adapter and other hardware become increasingly important.

6. Check Your Ethernet Cable

Your Ethernet cable can also affect wired performance.

Very old or damaged cables may limit the connection between your router and device.

For most home Gigabit Ethernet connections, a good-quality Cat5e or Cat6 cable is normally sufficient. Cat6 is a sensible choice when buying new cables.

More expensive cable categories will not automatically make your internet faster if your router, network adapter or Unifi package is the actual limiting factor.

Check that:

the cable is not damaged;
connectors fit properly;
the computer is negotiating the expected Ethernet speed;
your network adapter supports the speed you are trying to test.

This becomes especially important when troubleshooting 1 Gbps and higher connections.

7. Disconnect Devices You Are Not Using

Your internet connection is shared between the devices using it.

Phones, smart TVs, computers, tablets, gaming consoles, CCTV systems and smart-home devices can all use bandwidth.

Some devices continue transferring data even when nobody is actively using them.

Common background activities include:

cloud backups;
Windows or macOS updates;
game downloads;
app updates;
Google Drive or OneDrive syncing;
automatic photo backups;
security-camera uploads;
streaming.

Before running an important speed test, temporarily pause large downloads and other bandwidth-heavy activities.

You don’t normally need to disconnect every device in your home, but reducing heavy background traffic will give you a clearer picture of your connection.

8. Check Whether One Device Is the Problem

Sometimes the internet connection is fine but one particular phone, laptop or computer performs poorly.

Run the same speed test from at least two devices.

If one device receives 400 Mbps while another struggles to reach 100 Mbps from the same location, investigate the slower device before blaming the internet connection.

Possible causes include:

an older WiFi adapter;
outdated drivers;
power-saving settings;
background downloads;
VPN software;
malware;
older hardware;
connecting to 2.4 GHz instead of 5 GHz;
a 100 Mbps Ethernet port.

This test can save a lot of unnecessary router troubleshooting.

9. Stop VPNs and Large Background Downloads

A VPN sends your traffic through another server and adds another part to the connection path.

Depending on the VPN provider, server location, encryption and server load, this can reduce measured speed and increase latency.

If you are troubleshooting Unifi performance, temporarily disconnect your VPN and run another test.

Also pause:

torrent downloads;
cloud synchronization;
game updates;
operating-system updates;
large uploads;
4K streaming on other devices.

If your speed improves significantly, the Unifi connection itself may not be the problem.

10. Update Your Router When Necessary

Router manufacturers occasionally release firmware updates to improve security, stability and compatibility.

If your router supports user-managed firmware updates, check the correct manufacturer instructions before changing anything.

However, be careful with routers supplied or managed by Unifi. Do not install unofficial firmware or make major configuration changes unless you understand the consequences.

Also avoid performing a factory reset simply as a general speed-improvement technique. A reset can remove settings that may need to be configured again.

If you only need to change your WiFi credentials, see our guide on how to change your Unifi WiFi password.

11. Consider Mesh WiFi for a Larger Home

A faster internet package does not automatically mean better WiFi coverage.

If the router is downstairs and your bedroom is upstairs at the opposite end of the house, even a very fast fibre connection may perform poorly there.

Mesh WiFi can help extend wireless coverage throughout a larger property.

It can be particularly useful for:

double-storey homes;
large houses;
long floor plans;
rooms separated by several walls;
areas where the main router signal is consistently weak.

The goal of a mesh system is not to make your subscribed internet package faster. Its main purpose is to provide a stronger and more usable wireless connection across a larger area.

Unifi offers WiFi and Mesh options for compatible customers, but availability and equipment can change over time. Check the latest official Unifi information before purchasing or adding equipment.

12. Don’t Expect Every WiFi Test to Match Your Package Speed

This is one of the most important things to understand.

If you subscribe to a certain Unifi speed, it does not mean every device in every room will show exactly that number in every speed test.

Your measured result can be affected by:

WiFi signal strength;
router capability;
WiFi generation;
device hardware;
frequency band;
walls and distance;
other connected devices;
background downloads;
test server;
Ethernet port speed;
network congestion.

For example, a device with older WiFi hardware may become the bottleneck even when the fibre connection itself is much faster.

This becomes increasingly noticeable with higher-speed packages such as 500 Mbps, 1 Gbps and 2 Gbps.

If you want to understand these limitations in more detail, read our guide to the factors that affect your internet speed.

13. Don’t Upgrade Your Unifi Plan Before Finding the Bottleneck

If your current internet feels slow, upgrading to a faster package may help—but only when your existing package is genuinely the limiting factor.

Suppose poor WiFi coverage is causing slow internet in an upstairs room.

Upgrading the fibre package may still leave that room with a weak signal.

Before upgrading, ask:

Is my speed good over Ethernet?
Is performance only poor far from the router?
Is my device capable of faster WiFi?
Are too many users sharing the current package?
Are large downloads regularly using all available bandwidth?
Is the router suitable for my home?

If several people regularly stream, game, download large files and make video calls at the same time, a faster package may be worthwhile.

But solve WiFi coverage and hardware bottlenecks separately.

14. Check for Unauthorized WiFi Users

If people outside your household have access to your WiFi password, they may use your connection without you realizing it.

Check the connected-device list in your router interface if you know how to access it.

If you see unknown devices:

Change your WiFi password.
Use WPA2 or WPA3 security when supported.
Avoid easy-to-guess passwords.
Reconnect only devices that you recognize.

A strong WiFi password protects your network and prevents unwanted users from consuming your bandwidth.

15. Test at Different Times

One speed test does not tell the whole story.

Try testing:

in the morning;
during the afternoon;
during the evening;
when your household is busy;
when other devices are idle.

Keep the testing conditions similar so the results are easier to compare.

If your wired connection is consistently good but WiFi performance changes depending on your location, focus on your home WiFi setup.

If wired performance is consistently much lower than expected across multiple devices and at different times, the issue may require further investigation.

When Should You Contact Unifi?

Consider contacting official Unifi support when:

your connection frequently disconnects;
the router or fibre equipment shows warning lights;
there is no internet connection;
multiple devices experience the same problem;
wired speeds remain unusually low;
restarting your equipment does not help;
the problem continues for an extended period.

Before contacting support, record a few speed-test results and note whether they were taken through WiFi or Ethernet.

For billing, account problems, outages, installation or line faults, always contact official Unifi/TM support. UnifiSpeedTest.com is an independent website and cannot access or modify your Telekom Malaysia account.

How to Get the Most Accurate Unifi Speed Test Result

For the most reliable comparison:

Use a modern laptop or computer.
Use Ethernet when possible.
Disconnect your VPN.
Pause downloads and uploads.
Close bandwidth-heavy applications.
Reduce heavy internet use on other devices.
Run the test several times.
Compare WiFi and Ethernet results.
Check the capabilities of your device and network adapter.

You can then run the Unifi Speed Test again and compare the results.

Final Thoughts

Slow Unifi internet does not always mean there is something wrong with the fibre connection.

In many homes, the real bottleneck is WiFi coverage, router placement, connected devices or the hardware being used to access the internet.

Start with a speed test, compare WiFi and wired performance, and then work through the possible causes one at a time.

Simple changes such as moving closer to the router, switching to 5 GHz, stopping background downloads or using Ethernet can make a noticeable difference without changing your internet package.

Frequently Asked Questions

Why is my Unifi internet speed slower than my package?

The speed measured on a device can be lower because of WiFi signal strength, router limitations, device hardware, other connected devices, background traffic and the speed-test environment. Test using Ethernet when possible to help separate an internet-line issue from a WiFi issue.

Does restarting the router improve Unifi speed?

Restarting can solve temporary networking problems, but it does not increase the maximum speed of your subscribed package. If you need to restart the router frequently, another issue may be causing the problem.

Is 5 GHz better than 2.4 GHz for Unifi?

5 GHz usually provides faster WiFi when you are relatively close to the router. 2.4 GHz generally reaches farther and passes through obstacles better but usually provides lower speeds and can experience more interference.

Why is Unifi fast with Ethernet but slow on WiFi?

This usually indicates that your fibre connection is performing better than your wireless network. Router location, distance, walls, interference, WiFi band and device capability can all reduce wireless speeds.

Will buying a new router make my Unifi internet faster?

A better router can improve WiFi coverage, wireless capacity and local network performance when the existing router is the bottleneck. It cannot make your internet connection exceed the speed provided by your Unifi package.

Does changing DNS increase Unifi download speed?

Normally, changing DNS does not increase the actual bandwidth of your Unifi connection. A faster DNS service may make domain-name lookups feel more responsive in some situations, but it will not turn a slow broadband connection into a faster package.

Should I use Ethernet for a Unifi speed test?

Yes, when possible. A wired test reduces the effect of WiFi signal strength and interference, making it easier to judge the performance of the connection itself.

Why does my Unifi speed change throughout the day?

Speed-test results can vary because of household usage, WiFi conditions, device activity, test-server load and network conditions. Testing several times under similar conditions gives a more useful picture than relying on one result.

Match a persistent symptom to the next investigation: use the Unifi speed-stuck-around-100-Mbps checklist for a repeated wired ceiling, or the evening slowdown test log for a problem that appears at particular times.
