Are you having trouble with your Wi-Fi signal again?

Wireless signals can often drop out for no apparent reason, and therefore, getting frustrated with your internet connection can seem like second nature.

However, most of the time you’ll find that the issue isn’t with your internet connection itself, but the Wi-Fi signal being broadcast from your modem or router. It’s important to understand the difference!

Here are a few ways you can improve your Wi-Fi signal and performance of your modem/router.

1. Locate the best place for your modem router

If you’re a designer, having your router out in the open may clash with your aesthetic. But if you want and need the best Wi-Fi signal in your home, this is something you’ll just have to deal with it.

Make sure your modem/router is in the centre of your home so that you have the best possible coverage everywhere. If it doesn’t lay flat on a surface, consider elevating it and mounting it on a wall for better coverage. Most importantly, never place your modem/router behind another appliance, like a TV.

2. Try to avoid interference

Modem/routers have a number of elements at work against them as they are relying on wireless signals. Appliances in your home or office, like microwaves and cordless telephones, can interfere with the signal.

A dual-band modem router (meaning a device that has two Wi-Fi networks to connect to) can assist, but that’s not always the solution. It’s very important to try and keep your modem/router away from appliances to ensure you are getting the best Wi-Fi signal at all times.

3. Find the right Wi-Fi channel

The modem/routers in other buildings or nearby homes may also interfere with your Wi-Fi signal. Wireless routers can operate on a number of channels, so finding the right one will save you plenty of headaches.

You can try using a tool like Microsoft’s Wi-Fi Analyzer on your computer to locate the best channel and then log into your modem/router and change the channel on your Wi-Fi bands. You can test different Wi-Fi channels and see which channel works best for your devices and your home environment as this will always vary.

4. Keep your network secure

Your neighbours or people nearby who want to siphon your internet connection can mess with your signal if they know what they are doing. Make sure you lock down your network and enable password protection to prevent other people using your internet connection.

5. Control your bandwidth applications

There are certain applications that will use a lot of bandwidth, making it difficult for everyone else in your home to get a strong internet connection. Online gaming, HD and 4K Netflix, video chats and other applications should be put in order of Quality of Service (QoS). This will help you prioritise applications so the most important apps get the most bandwidth, therefore providing a better experience.

6. Increase your range

There are a few different things you can do to extend your Wi-Fi range. Getting yourself a mesh system to add on would be the best solution. A Wi-Fi mesh router will help your Wi-Fi connection stay strong in and around your home and is much recommended over a Wi-Fi range extender, which we find can cause other issues.

Mesh Wi-Fi systems usually consist of a main router that connects directly to your modem, and a series of modules placed around your home to provide the best Wi-Fi coverage. They link together and form part of a single wireless networ, so this means they share the same Wi-Fi name and password.

7. Set a reboot schedule

If you find yourself having to repeatedly reboot your modem/router from time to time, putting it on an automatic schedule can be helpful. Put it on a timer to reboot when you don’t usually use the internet (when you’re sleeping). This way, it will reboot on its own, and you won’t have to worry about interruptions to your Wi-Fi signal, especially if the modem/router is in a spot that is not easily accessible.

8. Avoid network overload

If you have a large family, chances are your network is being used triple time. When you are having an event, or one of the kids are having a study session, that’s additional use of your Wi-Fi. This may cause your network to become overloaded, and devices will disconnect. One way to ease this problem is to take some devices off the network that you aren’t using. You can also use software that controls bandwidth to prevent dropping.

9. Get a new modem/router

If you’ve had your modem/router for a number of years, there’s no question – it’s probably outdated. You want to make sure you are capitalising on your bandwidth, so getting an up-to-date router that is more efficient can work wonders.

10. Update your firmware or network driver

This is an easy fix. If you are experiencing issues and you have a fairly new router, update the network driver and the firmware on your device and you should be good to go.

More Guides


1. Please be sure that when the computer is connected to your internet modem, the internet works fine without dropping. If the internet is not stable, please contact your internet service provider to do some troubleshooting. If it’s a modem/router, please contact your ISP make sure internet line is good.

2. Please check that whether the internet is stable or not when the computer is connected to the router with a cable. If not, please try to change the Ethernet cable, LAN port and computer to carry out a test. Also, you can go to the Download Center to upgrade the firmware of your router if it is not the latest one.


Wireless devices intermittently disconnect from the wireless network, while wired devices are still connected and working ok. And the firmware of the router is already upgraded to the latest one.


In most cases, this problem is caused by local environmental factors that affect the wireless signal.


1. Locate wireless clients in a reasonable distance. The farther distance away from the router, the weaker wireless signal will be. Try moving closer to the router to see if the connection improves.

2. Get away from obstacles. Keep the router in the most central spot in the home and away from anything that might block its signal such as metal objects, bodies of water, reinforced concrete walls, foil-insulated walls, and other similar construction materials may severely weaken a wireless signal passing through it.

3. Reduce the number of wireless clients. The more devices are sharing the wireless network, the less bandwidth is available for each device to use.  One or two devices may be ‘hogging’ bandwidth. Try disconnecting some of the devices to improve performance on other devices. You may carry out the test by adding one device at a time to the wireless network to check for the maximum number of devices you can use before bandwidth becomes compromised.

4. Decline interference from other wireless equipment. All wireless devices are trying to send data over the air. Cordless phones, baby monitors, Bluetooth devices (i.e. wireless speakers, mouse) and neighboring wireless networks are all competing with your wireless network. Move Wi-Fi devices away from other transmitting devices, or turn them off when they are not in use.

5. Optimize the router’s position. For routers with antennas mounted on the outside of the casing, try adjusting the orientation of the antennas for maximum performance. We recommend placing it up high and also placing its antennas at 45 degrees (diagonally) or 0 degrees (straight out parallel to the floor), which will be more effective. Since antennas always transmit weakly at the base, do not place your wireless client device at the bottom of TP-LINK wireless device.

6. Change some settings on the router. If the issue still persists then you could try changing some wireless settings on the router. You will have to log into the router’s management page. 

One thing to try is to change to a different wireless channel. Under the wireless settings it is also important to check the Country/Region. If it is set to a different location from you, then you may come across similar issues with the wireless disconnection. 

Below is an example for wireless router. Please click on Wireless Settings below the setup menu. Change the Channel (channels 1, 6 and 11 are generally best, but any channel can be used).   Also, change the channel width to 20MHz which will provide you a more stable and less crowded wireless environment.

Click Save, reboot the router, and test for improvement in performance.

Please also be sure that you’ve enabled a strong password protection for the router wireless to avoid others connecting to your wireless.

7. Test the WIFI device. If all other devices are getting continuous wireless connection, but some individual device is suffering from an intermittent wireless network, it may due to the device itself that can’t function well.  Please try to use the device on another network, or another location to check the performance of the device.  Or just try to update the system or wireless adapter’s driver to latest one to see how it goes.Is this faq useful?
