Why Is My Internet Slow?

A slow Internet connection does not necessarily mean that your broadband plan is too slow.

Your actual Internet experience can be affected by your Wi-Fi connection, router placement, connected devices, network congestion, device capability, interference and even problems outside your home.

The major broadband providers in Malaysia provide similar troubleshooting advice. Unifi's EasyFix allows customers to self-diagnose Internet connection, Internet speed and Wi-Fi problems before contacting TM. (Unifi EasyFix)

Maxis recommends checking Wi-Fi connectivity, Internet speed, connected devices, restarting the router and checking router placement when troubleshooting common Wi-Fi problems. (Maxis)

CelcomDigi also highlights Wi-Fi frequency, router placement, the number of connected devices and the importance of using an Ethernet connection when checking whether your actual broadband speed matches your subscribed plan. (CelcomDigi)

TIME similarly recommends checking router placement, restarting the router, managing connected devices, choosing the appropriate Wi-Fi frequency and checking your devices. (TIME)

So before you conclude that you need a faster broadband plan, find out where the problem actually is.

1. Check If There Is an ISP Outage

Before changing anything at home, check whether your ISP is experiencing a service problem.

Maxis specifically recommends checking with your ISP for outages when troubleshooting Wi-Fi and Internet problems. (Maxis)

Unifi also publishes network alerts showing affected areas, causes and service restoration updates. (Unifi Alerts)

TIME provides a Service Status page where customers can check their service status using their Service ID. (TIME Service Status)

If there is a confirmed outage, changing your Wi-Fi settings or upgrading your broadband plan will not fix the underlying network problem.

2. Find Out Whether the Problem Is Your Internet or Your Wi-Fi

This is one of the most important troubleshooting steps.

Your connection can be thought of as:

ISP Network → Fibre Connection → ONT/Modem → Router → Wi-Fi → Device

A problem at any point can make your Internet feel slow.

For example, if your fibre connection is working normally but the Wi-Fi signal is weak in your bedroom, upgrading from 300Mbps to 1Gbps may not solve the problem.

CelcomDigi specifically recommends connecting a PC or laptop directly to the router using an Ethernet cable when checking the actual broadband speed. (CelcomDigi)

This gives you a much better starting point for determining whether the problem is the broadband connection itself or your home Wi-Fi.

3. Test Your Broadband Speed Correctly

If you want to know whether your broadband connection is actually slow, don't rely only on a Wi-Fi speed test.

CelcomDigi recommends connecting a PC or laptop directly to the router using an LAN/Ethernet cable and then running a trusted speed test. (CelcomDigi)

Maxis also explains that an Ookla speed test measures the Wi-Fi speed at your device, meaning distance from the router and physical interference such as concrete walls can affect the result. (Maxis)

For a more useful test:

1. Connect your computer directly to the router using Ethernet.
2. Stop large downloads and uploads.
3. Pause cloud backups and game updates.
4. Close unnecessary applications.
5. Run the test more than once if necessary.

The objective is to determine whether the incoming broadband connection is slow, rather than simply measuring the limitations of your Wi-Fi.

4. Check How Many Devices Are Using Your Internet

Your Internet can become slower when several devices are performing bandwidth-heavy activities at the same time.

TIME specifically advises users to check whether multiple connected devices are simultaneously performing high-bandwidth activities such as high-quality video streaming, large file synchronisation, torrent downloads and game or application updates. (TIME)

Maxis similarly recommends identifying devices that are consuming large amounts of bandwidth and temporarily limiting or disconnecting them when troubleshooting slow Wi-Fi. (Maxis)

CelcomDigi also notes that multiple devices performing data-intensive activities such as streaming, gaming and video conferencing can reduce the speed experienced by each device. (CelcomDigi)

So before upgrading your broadband plan, check what your household is actually doing online.

5. Check Whether You Are Using 2.4GHz or 5GHz Wi-Fi

Your Wi-Fi frequency can make a noticeable difference.

According to CelcomDigi, 5GHz generally provides faster speeds but has a shorter coverage distance, while 2.4GHz generally provides wider coverage but slower speeds. (CelcomDigi)

TIME provides similar guidance, noting that 5GHz is useful when you are closer to the router, while 2.4GHz can be more suitable when you are further away. (TIME)

In simple terms:

5GHz

1. Usually faster
2. Better for devices close to the router
3. Shorter range

2.4GHz

1. Usually slower
2. Longer range
3. Can be useful further from the router

If your Internet is fast beside the router but slow in another room, the issue may be Wi-Fi coverage rather than your broadband plan.

6. Check Your Router Placement

Where you put your router can have a significant impact on Wi-Fi performance.

TIME recommends placing the router in an open and central location, preferably elevated, while avoiding interference from electronic equipment and other obstacles. (TIME)

CelcomDigi similarly recommends placing the router in a central location with plenty of space around it and away from electronic devices that may interfere with the Wi-Fi signal. (CelcomDigi)

Maxis also recommends placing the router centrally, away from walls and large furniture, and elevating it to improve signal distribution. (Maxis)

Avoid placing your router:

1. Inside a cabinet
2. Behind large furniture
3. On the floor
4. In a corner of the house
5. Near sources of interference

Sometimes, simply moving the router can improve your Wi-Fi more than upgrading your broadband speed.

7. Restart Your Router

Restarting your router is another basic troubleshooting step.

TIME recommends switching off the router, unplugging it, waiting 10 seconds and then powering it back on. (TIME)

Maxis recommends switching off and unplugging the router for around 30 seconds before reconnecting it and allowing it to fully restart. (Maxis)

CelcomDigi's troubleshooting flow for mesh users similarly recommends turning off the modem, router and mesh units, waiting, and restarting them in sequence. (CelcomDigi)

However, do not factory-reset your router unless necessary.

A factory reset can erase your existing Wi-Fi and network configuration.

8. Check Your Device

If only one device is experiencing slow Internet, the problem may not be your broadband connection.

For example:

Phone A: Slow

Laptop: Normal

Smart TV: Normal

In this situation, check the affected device before blaming the broadband connection.

CelcomDigi notes that older devices which only support 2.4GHz Wi-Fi may not be able to achieve the full speed of a subscribed plan because the device itself can be a limitation. (CelcomDigi)

TIME also points out that real-world Wi-Fi performance can be affected by physical obstructions, interference and device compatibility. (TIME)

Try:

1. Another device
2. Another browser
3. Updating the device
4. Disconnecting and reconnecting to Wi-Fi
5. Testing the device closer to the router

9. Check Your Ethernet Cable

If you are using a wired connection to test your broadband speed, the Ethernet cable itself can also become a bottleneck.

TIME currently lists the following typical cable capabilities:

1. Cat 5: Up to 100Mbps
2. Cat 5e: Up to 1Gbps
3. Cat 6: Up to 10Gbps

Actual performance still depends on your network equipment and other hardware. (TIME)

This is particularly relevant if you recently upgraded to a higher-speed broadband plan but are still using older networking equipment.

10. Check Whether Your Router Can Handle Your Broadband Speed

A faster broadband plan is only useful if your network equipment can handle it.

TIME recommends checking whether your router is compatible with your new subscribed speed after upgrading a plan. (TIME)

This means that when troubleshooting slow Internet, you should not only look at your broadband plan.

Also consider:

ISP connection → ONT → Router → Wi-Fi → Device

Any one of these components can become a bottleneck.

When Should You Consider Upgrading Your Broadband Plan?

This is where consumers need to be careful.

If your wired speed is normal but Wi-Fi is slow, upgrading your broadband plan may not solve the problem.

If your wired connection is consistently below expectations across multiple tests and devices, contact your ISP and ask them to investigate the connection.

If your connection is working properly but your household regularly has several people streaming, gaming, downloading and working simultaneously, then you may genuinely need more bandwidth.

CelcomDigi notes that households with frequent simultaneous data-intensive usage may want to consider a higher-speed plan, while Maxis similarly explains that greater bandwidth can provide more capacity for multiple users and devices. (CelcomDigi) (Maxis)

But that should be a decision based on actual usage, not the first solution you try.

When Should You Contact Your ISP?

Contact your ISP if:

1. Wired speeds remain consistently much lower than expected
2. Multiple devices experience the same problem
3. Your connection repeatedly disconnects
4. Restarting your equipment does not help
5. You suspect an ISP network problem
6. Your provider's diagnostic tool identifies an issue

Unifi's EasyFix allows customers to self-diagnose and troubleshoot before contacting TM, and if self-troubleshooting does not resolve the issue, Unifi says a report can be automatically created or the customer can access Live Chat. (Unifi)

TIME also directs customers to Live Chat if troubleshooting does not resolve the connection problem. (TIME)

NetBijak's Take

A slow Internet connection does not automatically mean that you need a faster broadband plan.

That is probably the most important thing consumers should understand.

If you subscribe to 500Mbps but your phone only receives 80Mbps over Wi-Fi, that does not immediately mean your ISP is failing to provide 500Mbps.

Your Wi-Fi frequency, router placement, device capability, interference and household usage could all be contributing to the result. This is consistent with troubleshooting guidance from Unifi, Maxis, CelcomDigi and TIME.

At NetBijak, our recommendation is simple:

Troubleshoot first. Upgrade second.

If the wired connection is healthy but Wi-Fi is poor, look at the Wi-Fi environment.

If one device is slow while others are normal, investigate the device.

If several devices are slow and the wired connection is also consistently below expectations, contact the ISP.

And if your Internet is working normally but your household genuinely needs more capacity, then a faster plan may make sense.

The goal should not be to sell you a faster package.

The goal should be to help you understand what is actually causing your slow Internet before you spend more money.
