There can be many reasons behind network connectivity troubleshooting issues. It can be hardware
failure, router failure, interruption because of other electronic devices and internet service provider’s
planned outages.
Before starting the troubleshooting, we should scan our PC with anti-virus to check if it is free from
malware and viruses. After running an antivirus scan, we should delete cookies and temporary files from
our computer, as they may be the reason behind our computer’s slow performance. We should also call
up our internet service provider and ask if there is any problem with their service or any kind of planned
outage in our area.
Modem or wireless dongle issues
This is the simplest step that can solve the network connectivity problem without putting in much time
and effort. All you have to do is shut down the modem from the main switch, and start it back after two
minutes. In case of hardware or modem failure, we won’t be able to see any indicator on the modem.
Computer’s task manager issues
Network troubleshooting should always begin with opening the computer’s task manager. After
opening the task manager, just select networking. The networking section will show if the internet
connection is active or not. If the connection is not active, we should check the modem or wireless
dongle indicator.
Check network settings & version of device driver
Network connectivity issues can also occur if network service settings are incorrect. One should check
service settings, login settings, and adopter settings if we are not able to get connected to the network
even if the network signals are strong.
Network settings will automatically change whenever we reinstall our computer’s operating systems or
device drivers. After reinstalling the operating system or device drivers, we should check if the version of
our ISP’s device driver is compatible with our new operating system or not. We will have to download a
compatible version in case if the old one is not compatible.
Check the network’s cell signal strength
The browser and other applications on your computer will not work if the ISP's signal strength is very low.
Our computer’s task manager can show us our internet service provider’s signal strength. A number of
factors around our computer can reduce the network’s signal strength. Devices like Microwave, radio,
mobile phone and other electrical devices should be kept at least 1m away from our computer as they
can interfere with internet service provider’s signals and reduce the signal strength.
Signal strength can also reduce in case of too much load on the internet service provider’s network.
There is nothing much that we can do in this situation, except for calling our ISP to log a complaint.
Problems while authentication
If we are putting an incorrect user name or password in the network settings, we will get an error that
says “authentication failure”. In this case, we should try to reset our password or just call the internet
service provider’s customer service number.
A proper, consistent and logical approach is necessary for troubleshooting network connectivity issues.
Hitting your PC will not help. There is no need to be tech-savvy to understand some basic connectivity
issues. The above tips can help you to solve basic issues all by yourself.
