Since 2004, eTechs have been installing and maintaining Wi-Fi networks for homes and businesses across South Australia.

Find and fix the most common issues with Wi-Fi

Wi-Fi systems these days are very reliable. Homes and businesses use Wi-Fi to connect smart devices to the Internet with seamless connectivity, day in, day out, with no problems. We rely on it so much we barely even think about how we're connected. It's always on, always there... until it's not.

Most of us can't be without an Internet connection these days. It's so ingrained in our daily lives, both at home and at work, that we need it to be available always. So when it stops working, getting back online becomes a huge priority.

The following steps will show you how to troubleshoot and fix Wi-Fi connection issues on your own to get you back online fast.
For the purposes of this article, we will presume you are using a modem/router, all in one device that connects to your Internet and also sends out the Wi-Fi signal. We will call this device the 'router'.

Can't connect to the Internet in some parts of the home

Wi-Fi is a radio signal. Your router uses radio waves to communicate with your device, and sometimes these signals aren't strong enough to reach into certain parts of a home.
This is usually due to the number of walls the signal has to travel through.

To solve this issue, if possible, move your router closer to the centre of the home. If you have FTTN, or FTTC connections, you may be able to move the router to a different telephone outlet in your house, one that's more central.

For NBN HFC, or FTTP, that won't be possible. In those cases you could try purchasing a Wi-Fi repeater or a mesh system to broadcast your signal into the areas your current router is struggling to reach. Repeaters and mesh systems are generally an inexpensive way to solve poor Wi-Fi coverage, compared to re-cabling your modem to a more central location.

Slow Internet on all Wi-Fi connected devices

If your Internet speeds suddenly become noticeably slower, even when you're right next to the router, you'll need to establish whether the issue is with your Internet connection to the ISP or just an issue with the Wi-Fi.
First, using your Wi-Fi connected smart device, phone, tablet or laptop, browse to This site will run an automatic speed test and show you the results.

Then, plug a laptop or PC directly into a 'switch' port on the back of the router using an Ethernet cable. Run the same test by going to and noting the result. If the speed result is still slow with the cabled connection, the issue is likely to be with the the Internet connection itself. Contact your ISP/RSP to report the issue.

If, however, the speed result is significantly better on the hardwired connection, follow the steps below.

Reboot equipment

You've most likely already done this, and sick of the amount of times you have, but if not, you'll want to reboot the router as well as the device you're using to connect through Wi-Fi. You'd be surprised at how often this fixes connectivity issues. So reboot and see if that resolves the issue.

Wi-Fi Signal Scan

Failing that as a resolution, the issue may be interference from another router close-by, a neighbour in the next house or apartment. To determine if that could be causing the issue, you can do two things. Both require some technical understanding, and also confidence in router configuration.
You can download free software apps on Windows, Android and Linux to scan for Wi-Fi signal strength in your area, and what channels they are broadcasting on.

Some good, free, software for Windows is NetSpot and for Android we recommend Wifi Analyzer. Both will show the channel signal strength of all broadcasting routers nearby.

If you find a neighbouring router is broadcasting a strong signal using the same channel as your router, change your channel to get away from theirs. This should resolve the interference issue.

NOTE - As of this writing, since releasing IOS14.x, Apple do not allow developers to show Wi-Fi channel signal strength in their apps anymore. This means no signal testing is available on iPhone or iPad anymore. You'll want to use an Android, Windows, or Linux device to test signal strength.

If you don't have access to anything other than Apple IOS devices, you can always just cut to the chase and change the channels your router is using to broadcast Wi-Fi. Log into your router's WiFi settings and change both the 2.4GHz and 5Ghz channels. Connect to the 2.4GHz channel and run the speed test again. Connect to the 5Ghz channel and run the speed test again. You should try a few different channels and see if any improve the connection.

Losing Wi-Fi regularly

If you find your Wi-Fi is consistently dropping your connection, it could be due to quite a few things. We'll cover the main ones here.

Is there a pattern?

Look for a pattern. Does it only happen when there's something in the microwave for instance. There are many signals that can interfere with Wi-Fi.

If there is no pattern to the issue, and you can't find any interference using the network scanning tools, it may be that your router needs a firmware upgrade. Firmware upgrades are usually put out by the manufacturers to fix bugs found in their operating system.
Find instructions on how to upgrade your firmware in your router's user manual, or online by searching for instructions online.

Find your firmware update by router brand

Firmware upgrade did not fix the issue

If a firmware upgrade did not fix the issue you're having, it could be that the router is faulty. This can happen from brand new, but is most likely to happen when the router is a few years old. Even though some components inside will still be working fine, being modular, the Wi-Fi board may be on its way out.
If the router is still in warranty, try getting it replaced. If not, before spending money, ask around your friends and family. Usually someone has an older router sitting around you could loan. See if theirs gives you a stable connection. If so, it's probably time to bite the bullet and purchase a new one.

No Internet on any device
Understanding Your Router's Status Lights

Most routers will show you the current status of its operation by its illuminated icons. These can vary, depending on the router model, but most will have the basic status indicators. Either words or icons will be used;

  • 'WAN' or Globe Icon: This is solid when the modem is connected to the Internet.
  • 'Wi-Fi' or Icon: Solid light when Wi-Fi is on and broadcasting.
  • 'LAN' or Icon: Solid when Ethernet connected devices are working.

WAN or Globe light is off

If the 'WAN' or Globe icon light off, or steadily blinking, this means your Internet is disconnected. You'll want to check all cables are plugged in correctly first, and if they are, call your ISP/RSP to lodge a fault ticket with them.

Wi-Fi light is off

If the 'Wi-Fi' light is off: Some routers have a button that switches Wi-Fi on and off. It could be that someone has accidentally pushed the Wi-Fi button.
If that is not the case, you'll want to log into the router via Ethernet to check whether a router upgrade has switched of the radios for some reason.
If neither of those are the cause, it's likely that your router is faulty.

WAN and Wi-Fi lights are on

Try plugging a laptop or computer into the router using Ethernet. The 'LAN' light should become solid. If you have Internet via a cabled connection, and all settings in the modem regarding Wi-Fi appear to be correct, it could be that your router is faulty.

Replacing your router

If the router is still in warranty, try getting it replaced. If not, before spending money, ask around your friends and family. Usually someone has an older router sitting around you could loan. See if theirs gives you a stable connection. If so, it's probably time to bite the bullet and purchase a new one.

Not Comfortable With Technical Troubleshooting?

If you're not confident with technical issues, the above steps can be overwhelming. Understandably, you can't know everything about everything, and sometimes don't have the time to teach yourself.
If you've tried to resolve the issue as best as you can, with no luck, it might be time to employ the services of someone who can quickly get to the bottom of the issue, saving you from the stress and headaches of trying to work it out on your own.
Ask around your immediate family and friends. It may be that someone around you has the expertise to resolve the issue, or at least advise you on a reasonable course of action you should take to move forward.
Failing that, if you choose to employ the services of a professional company to resolve your issue, make sure they are proficient in Wi-Fi troubleshooting. Not every IT company is the same.
