How To Fix WiFi Problems And No Internet Connection

Many times, we encounter the puzzling conundrum of a full WiFi signal on our device but no internet connectivity. We usually fumble to a solution without rhyme or reason.

Before you stomp off to call your internet service provider, founder in your explanation to customer support, and then wait an inordinately long duration for assistance, there are a few things you can do to troubleshoot the problem yourself.

Reboot the router or modem

There’s a reason that rebooting is the first thing customer support staff tells us to do. Rebooting flushes the cache and usually does the trick of solving many small network problems. Turn off the router or modem (or both, if you have both), wait for 30 seconds, and then turn it back on again.

Modem lights

When there is a problem with the internet connection, the onus for repair falls on the internet service provider. Check that the “Internet” light, the power light and DSL lights on the modem are on. If the lights are off or flickering, you should contact your internet service provider immediately.

Device connectivity

If another device can connect to the network, there may be a problem with your device rather than the modem or internet connection. Restart your device, and if that does not work, check that it has been connected to the modem. Some devices may give the appearance that they are connected, but this may not actually be so. Sometimes when an incorrect network password has been entered, the device may still give the impression that the connection has been made. Check connectivity settings and use the inbuilt troubleshooter.

Flush your DNS cache

A DNS cache stores the previous websites that a user has visited. When a user types a URL into their browser, the operating system looks up the URL in the DNS cache. If it locates the URL, the operating system pulls out the website from the DNS cache without accessing the internet at all. The DNS cache can get bogged down with viruses and other malicious code from advertisements and popups, which can then prevent the browser from accessing the Internet. After flushing the DNS cache, restart the device and check for internet connectivity.

Outdated wireless mode

Every router carries with it a wireless standard which indicates the speed and the area of coverage. They appear in forms such as 802.11g, 802.11b, 802.11n and 802.11ac, which are prescribed by the IEEE organization. 802.11ac is the latest and fastest with a wide span of coverage, while 802.11b is older and slower with a small range. The latest wireless standards are usually compatible with all devices, but older devices may have a problem connecting to new standards. In this case, a procedure can be undertaken to identify the router details and change the wireless mode to a lower one to be compatible with your device

IP address conflict

Although a rare cause, IP address conflict occurs when two devices are assigned the same IP address. A simple command prompt can be used to assign a new IP address to your device.

Outdated network driver

An outdated or corrupted network driver can be the cause of a poor Internet connection. Again, a command prompt can be used so the device can automatically fix the network driver.

The next time your WiFi appears connected but you have no internet connectivity, go through the above list of problems first. As is evident from the list above, very often, the problem is minor and can be rectified quickly by the user itself.
