A strong, consistent Wi-Fi connection is critical for daily operations. From important data transfers to long-distance meetings, many crucial business tasks use the internet. But what happens when it stops working?
You are likely already familiar with the frustration this situation can cause. Files can’t be transferred, meetings have to be rescheduled, and cloud solutions become entirely useless. If these outages are persistent or last longer than a few minutes, your business can quickly lose steam – reducing productivity, profits, and customer satisfaction.
Fortunately, this is solvable. The majority of Wi-Fi issues are caused by a few common problems, many of which you can easily address on your own. So what can you do when your Wi-Fi is not working? Is there really a way to resolve outages without handing more work to your IT team?
Common Signs Your Wi-Fi Is Not Working
To fix your Wi-Fi issues, you must first know how to spot them. Not all IT problems are caused by a faulty internet connection. Here are some potential underlying causes of common issues:
Connection Cuts In and Out
Do your staff complain that their internet cuts out every five minutes? Do you find yourself needing to click “Connect to network” more often than usual? Frequent disconnections can be a sign of signal interference, outdated firmware, or issues with your service provider. If the outages are brief, they may be tempting to ignore – but when they occur on a regular basis, this often indicates an instability that could cause serious issues later.
Devices Say “Connected” But No Internet
Your device may report a working connection, but that doesn’t always mean the Wi-Fi is functional. If your internet connection seems to be fine but webpages aren’t loading, this could point to a modem or router problem – or even an outage from your internet service provider (ISP).
Only Some Devices Are Affected
If only specific devices are experiencing outages, the problem might lie with network settings or compatibility. This scenario is unlikely to be caused by the modem or router, as these errors tend to impact all connected devices.
Slow Internet Speeds Despite Fast Plan
Sluggish speeds that don’t match your plan may result from network congestion, outdated equipment, or connection interference. Occasional slowdowns can be normal depending on usage, but your overall internet speed should match the one promised by your ISP.
Wi-Fi Calling is Not Working
Wi-Fi calling allows you to use your internet connection for phone calls and SMS messages, instead of a traditional mobile network. This can be very useful for traveling or areas with poor reception. If you experience lag or your Wi-Fi calling is not working, this could be due to bandwidth limitations or network instability.

Troubleshooting General Wi-Fi Issues
As with any IT issue, fixing Wi-Fi outages will require a systematic approach. If you or others are having difficulty accessing the internet, follow these steps before you do anything else. In the vast majority of cases, one of these solutions will work.
Step 1 – Restart the Modem, Device, and Router
Often, turning it off and on again really is the solution. Restart your modem, router, and device, then attempt to reconnect to the internet. This process can clear temporary glitches and refresh your internet connection.
Step 2 – Try Connecting Manually
Many devices will attempt to connect to Wi-Fi automatically – but it’s common for problems to occur during this process. If you find that your internet is consistently reporting an error on start-up, turn this feature off in your Wi-Fi settings and attempt a manual connection. Your device may simply not be able to connect on its own.
Step 3 - Check Your Ethernet Cables
If Wi-Fi is not working, but Ethernet is, the issue is with your wireless connection specifically as opposed to an overall network error. Plug in a cable and check if you can use the internet that way. If you can, ensure that your Wi-Fi is correctly enabled and configured.
Step 4 – Reposition Your Router
Distance, physical obstructions, and electronic interference can all weaken your Wi-Fi signal. If you experience frequent outages in one area of the building, this is likely to be the issue. For example, you may find that computers placed near a break room have more trouble connecting – this may be caused by people microwaving their lunch, or taking phone calls. Place your router in a central, elevated location away from electronic devices that may cause interference. Try to keep as few physical barriers in the way as possible – such as walls or floors – as these can also result in a weaker signal.
Step 5 – Forget the Network
If the problem is specific to one device, click “Forget network” and try reconnecting from scratch. This may resolve configuration issues that prevent the device from connecting correctly. You may be surprised at how often this works.
Step 6 – Check Firmware and Settings
Outdated firmware will struggle to keep up with modern networks, resulting in connectivity errors. Access your router’s settings to check for updates. If the issue persists, consider resetting to factory defaults – someone may have accidentally changed a critical setting, or a broken update may have been installed.
Step 7 - Consider Physical Damage
If all else fails, your modem or router may have been physically damaged. This can happen in a variety of ways:
- It was knocked off of a surface onto the floor.
- Something heavy was stacked on top of it.
- It was struck by lightning during a storm.
If you cannot get to the bottom of your connectivity issues, consider ordering a replacement to rule out this possibility.
Provider-Specific Wi-Fi Issues and How to Fix Them
Each ISP is slightly different, and provides their own recommendations for troubleshooting Wi-Fi issues. Here is the advice given by some of the most commonly used providers:
Telstra Wi-Fi Not Working
- Ensure the modem light is turned on. If it is not, press the Wi-Fi or WPS button.
- Double-check that you’re trying to connect to the right network.
- Perform a speed test.
- Check the status lights on your NBN connection box.
If none of these work, contact support.
Optus Wi-Fi Not Working
- Perform a speed test.
- Check for local outages.
- Verify that all modem cables are securely connected, and that they are undamaged.
- Restart the device.
- If your modem was not supplied by Optus, follow their BYO modem setup instructions.
If these steps don’t resolve the issue, report a fault.
Dodo Wi-Fi Not Working
- “Power cycle” your hardware. This is when you turn it off, wait for ten seconds, then turn it back on. Dodo specifies that it may take up to ten minutes for a connection to re-establish.
- Perform an isolation test. This will involve disconnecting all devices, power cycling the modem, and then seeing if the Wi-Fi light displays correctly.
- If speeds are slow, check that you’re using the right plan for your needs.
TPG Wi-Fi Not Working
- Make sure Wi-Fi is enabled on all devices.
- Check that you are within range. TPG stresses that if you have moved out of range, your device will automatically disconnect.
- If the issue is limited to certain devices, test the wireless adapter to ensure functionality. You can do this by connecting to a different wireless network on the same device.
If all else fails, you can contact support here.
Belong Wi-Fi Not Working
Belong recommends logging into your account, navigating to “Manage your service”, and following their in-depth troubleshooting tool. More information is available on their internet FAQs page.
Device-Specific Fixes
If the issue is device-specific, there are a few additional things you can try. If general troubleshooting steps have not worked, and you believe the problem is isolated to a specific device, do the following things:
iPhone Not Connecting to Wi-Fi
If your iPhone is not connecting to Wi-Fi but other devices are, disable and re-enable your Wi-Fi in the settings. If that doesn’t work, power cycle your phone, then check for any updates. iPhone updates are meant to install automatically, but often don’t if conditions are not right – so it’s possible you missed one.
If all else fails you can try resetting the device to its original settings. This can be found under Settings > General > Transfer or Reset Device > Reset > Reset network settings. Be extremely careful, as this menu also contains the option to factory reset your phone, which will delete all content. Read the selections carefully, and do not under any circumstances choose “Erase All Content and Settings”.
Laptop or PC Wi-Fi Issues
For laptops or PCs, update your network drivers and ensure your firewall isn’t blocking the connection. If your drivers or operating system recently updated and you weren’t experiencing the issue before, try rolling back to a previous version and check if the problem persists. If it doesn’t, there may be a glitch present in the update.
Your device should also have a built-in network troubleshooting program. Try running this, as it may be able to detect and resolve the issue for you.
When to Contact Your Service Provider or a Tech Expert
If you have tried every step listed above and your Wi-Fi is still not working, it may be time to contact your ISP. It’s possible that the problem is on their end, or that it’s too complex for you to solve on your own.
How to Escalate the Issue Effectively
Before contacting your ISP, collect important information such as:
- Your account details.
- A brief, clear description of the issue.
- A list of the steps you have already taken to solve the problem (if you don’t provide this, they will likely take you through basic troubleshooting steps again, which may waste time).
- Any error messages you received. In particular, take a note of any error codes and the specific wording of the message, as this may help the ISP identify the problem.
Having this information on-hand will expedite the process. Once you are in contact with your ISP, follow their instructions carefully.
If you use a managed service provider (MSP) to handle IT tasks, speak to them as well. They should be very familiar with your infrastructure, and may be able to provide valuable insights on what the problem could be.
