Lost Internet Connection. Try Troubleshooting Internet Issues

Restart your device
Restart your device

The very first thing to do if your internet connection stops working is to restart your computer (laptop, smartphone, etc). Some operation system components may malfunction, which may lead to internet troubleshooting. Restarting your device will restart the OS and the chances are high that this alone will solve the issue.

The issue is with WI-FI or your internet signal?

When positive that your device (laptop, PC, smartphone) is not the one to blame for the internet trouble, we may go on testing the internet equipment.

Test the internet outage

If restart did not help and the internet connection issue remains, you’ll need to sort out if the issue is with an internet connection or the connection to wi-fi. So, the next thing to do is reboot the router. The situations when a router may freeze or malfunction happen often enough. Restarting it will solve the internet connection issue in many cases. To reboot the router, you need to unplug it from the power supply and then plug it in once again. A valid IP address should be issued automatically.

What do the lights on your equipment show

Simple yet effective advice is to check the light indicators on your internet equipment. If all the lights show in green there should be no internet connection issue. If some show in red, yellow or are not lit at all, this indicated there is some issue with receiving an internet signal. If you see red or yellow lights on the router then you should contact the internet service provider for further advice.

Connect to the router with Ethernet cable

If you have such cable then put it in use. The simple way is to connect your device with the router via an Ethernet cable and see if the internet connection restores now that you have direct access, no wi-fi intermediary. In case you have the internet when using the cable, then it must be the wi-fi (drivers) causing the issue.

Internet Signal Troubleshooting when Connected to Wi-Fi but cannot access the internet

You have figured out that you have internet access when using the cable, but it disappears when trying to use the wi-fi. In this case, you need to try fixing the wi-fi connection. Here is how to try to fix the internet:

1) Restart your device, wi-fi router and modem

There is no additional advice here, just press the power buttons on the modem, router, and your device (laptop, PC, smartphone, etc.) to power it off and then press it again to power it on. Such a simple act can solve the network problem.

2) Check all wires, cables

In the case of a PC, you will have a number of wires and cables, so it is a good thing to check if some of these got disconnected. A simple thing like this can be causing a network issue.

3) When is the time to contact internet provider

Once you have inspected the modem, router, checked the cables and wires but are still not sure where the problem is, it may be a good time to contact your internet service provider even if you don’t see yellow and red lights on the equipment.

Tips on Wi-Fi troubleshooting

The ISP will likely recommend troubleshooting wi-fi or do it for you remotely. Here is how you handle it.

1) Restart your router

One simple way how to fix the wifi router is to turn it off and turn it on again. It is easy and can prove to be effective.

2) Wi-Fi can be switched  

There will be markers on the router indicating the 2.4 GHz and 5 GHz bands. Try switching these and check the result.

3) Use different devices to test your Wi-Fi

When you encountered wifi problems using your laptop only, then it’s a good idea to test the wi-fi connection on your smartphone, PC, or tablet. This test will show that the problem is common or just localizes to a single device.

4) Try another Ethernet cable

If your ethernet cable is old or you are not entirely positive that it functions correctly, then just try another one.

5) Test different positions for your router and device

Simple but true, the positions of the router and your device matter. When the router is located high under the ceiling, try placing it somewhere lower, on the table for example. Then try placing your device closer to it and see if it helps with the internet connection.

Advanced troubleshooting

None of the simpler advice provided earlier helped and the ISP does not know what to do either? Then it is time to check for the possible software-related issues that will help to fix the wifi connection. Please follow such instructions:

For Windows device – run the internet troubleshooter

Windows internet troubleshooter

Each Windows device has a pre-installed internet troubleshooter program. Open the wi-fi preferences by pressing on the corresponding badge (by default located in the lower right corner) and press Run diagnostics

For macOS device – run the Diagnostics

The same is true for Apple devices. When encountering troubles with wi-fi internet access your MacBook should offer you to run the diagnostics even before you take action.

DNS cache can be cleared

In the Network Preferences, there is the DNS settings area (possibly in the Advanced section) where one can clear the DNS cache. This may fix your internet.

Scan for viruses

A virus can cause many issues, the online internet connection included. So go ahead and run your antivirus to see if this may be the problem cause.

Antivirus software can be switched

If no viruses are detected, try the exact opposite approach and switch off your antivirus program as it may just as well be causing the connectivity issue.

Try a different Wi-Fi channel

One other tip to fix the internet connection is to switch the wi-fi channel. When this is done you may run the internal and external speed test and see if any positive changes.

Instead of blindly configuring the router and other settings or troubleshooting the router, one may simply reset those to the factory defaults and do the fresh start. Although we advise doing it with the guidance of our consultant to do things right.
