Having a yellow triangle on your Wi-Fi icon often indicates issues with access to the Internet via Wi-Fi connection. Pointing to this triangle displays a quick message on the reason for the connection problem, such as: “Connected to the WLAN but no connection to the Internet”, “Limited or no connectivity” “No Internet Access” and some other similar messages.
There different possible reason why you may be having this issue. These reasons are in three main categories.
- Issues with the service provider
- Issues with your Wi-Fi router or Wi-Fi router settings.
- Issues with the network configurations on your laptop.
It is advisable to troubleshoot this problem in the order in which these categories are listed. So before changing any settings on your laptop, first check to see if the problem is coming from your internet service provider or your Wi-Fi router, especially if you’re using a private internet subscription.
Obviously, if you’re connected via a public service like campus network or city network, then you won’t be able to perform this test, in which case you should proceed with the other suggestions. However, if you are using a home Wi-Fi router or some kind of modem, then you can do a quick check to see if this is a problem with the service provider or with your router equipment.
TEST ONE: By-pass Wi-Fi Router and Connect Directly to your Laptop
To check for problems with the service provider, try to connect directly to your PC instead of passing through your router or modem, in that case you need to pull out the Cat 5 RJ45 cable or RJ11 (if you’re using a phone line) that goes into WLAN port on your Wi-fi router from the wall and hook it directly to the jack on your laptop, enter any logon credentials that might be required and wait for it to configure.
If the yellow triangle persists and you’re still unable to surf the web, then there’s a high probability that this problem is coming from your service provider, in which case you could contact your provider support service to help rectify the problem.
But if the yellow triangle disappears and you’re able to browse when this cable is directly connected to your laptop, then the next thing to check is your Wi-Fi router.
TEST TWO: Test Another Wireless Device on the Same Wi-Fi Access Point
A quick way to check this is to connect another wireless device, like another laptop or a mobile phone, to your Wi-Fi and see if this other device is able to access the internet connection. If it can’t then there’s a high probability that certain configurations or settings in your router is hindering the Wi-Fi connection for wireless devices.
In that case you will need to check the router settings. If you’re not sure how to do this, then you might need to seek the help of an expert. However, if some other wireless devices are able to connect and access the web from your router, then there is a chance that this problem is coming from your laptop, in which case you should apply one or more of the following fixes to try to resolve the issue.
SOLUTION 1: Run the Windows Network Troubleshooting Tools
There are two ways to do this, the first is to simply right-click on the Wi-Fi icon from the taskbar and select troubleshoot problems, then wait for the troubleshooting to complete.
Afterwards you should get a feedback from the troubleshooting on what problems were detected.
This rarely resolves such problems automatically, often it will give some suggestions on what next you can try to do in order to resolve this problem. Another way to troubleshoot this problem automatically is to go through windows settings by clicking on the gear icon from the Start menu.
On the page that follows, select update and security,
Then click on troubleshoot.
From the options, click on Internet connections and then wait for the troubleshooter to run.
Again you should get feedback from the troubleshooter after some time on what problems were detected and maybe you could get some suggestions on how to resolve this problem in your case.
SOLUTION 2: Reset Network Adapter
If the initial solution doesn’t resolve the issue, the next suggestion would be to reset your network adapter. Sometimes certain applications or malware could alter the configurations of your network adapter or drivers and prevent them from accessing the Internet.
In such situations resetting your network adapters could be a possible solution to this problem. To do that, go to your Windows settings and click on Network and Internet.
Next, go down to where it says Network reset and click on it.
Then on the page that follows, it tells you that this process will remove and reinstall all your network adapters, and then reset all your network components back to the original settings.
It also informs you here that your PC will restart, so before clicking on this Reset now button, ensure you save all your works and close all applications, then click Reset now. Hit yes and then click close and wait for your laptop to reboot.
Upon restarting, you should try to connect back to your wireless network and see if your internet connection now works properly again. If this doesn’t work, then try the next suggestion.
SOLUTION 3: Reset Windows Sockets API
Windows Sockets API is the API that determines how the network software accesses network services. So if somehow this API gets compromised by malware or some other malfunction, then it could also lead to these connection problems and resetting it back to default could be the solution.
To reset your Windows socket API, go to your Windows search and type, cmd, the right-click on the command prompt app from the search results and select run as administrator.
In the command prompt terminal, run the following commands one after the other:
netsh winsock reset
netsh int ip reset
Then restart your laptop and that should complete the reset process. Upon restarting, check to see if your connection now works fine. If not, try the next suggestion.
SOLUTION 4: Reinstall Network Adapter Drivers.
One way to do this is to uninstall them and restart your laptop for the drivers to reinstall automatically upon restarting. To do that open your search and type device manager, then click on device manager from the search results.
Go down to where it says Network adapters, click on the dropdown to reveal your network adapters.
Here you will find your Wi-Fi adapter, then right-click and select Uninstall device
Do not select delete the driver software for this device, because that would both uninstall and completely delete the network drivers, and since you have no internet connection then you won’t be able to download these drivers again, so here just click uninstall and wait for the process to complete.
Afterward you should then restart your laptop, and your network drivers should reinstall automatically.
SOLUTION 5: Update Your Network Adapter Drivers
Installing default network drivers from your laptop might resolve this issue in some cases. This is mostly applicable to situations where this problem started after running some major updates, then you may want to reinstall one of the default drivers recommended by Microsoft for your hardware.
To do that you need to go back to the Network adapters. From the device manager, right-click on wireless adapter and select updated driver.
On the window that follows, click on browse my computer for driver software.
Then you can choose the best match from the list, if you’re unsure of your Wi-Fi card model, then right-click on the Wi-Fi icon from the taskbar and select Open network and Internet settings.
Then click on Wi-Fi, and then hardware properties. A window like this should pop up.
Here the Wi-Fi card model is Intel Centrino advanced N-6205.
So for this example, I will select the best match from the recommended drivers and then proceed with the installation.
You can also try few of other drivers from the compatible ones to see if some other one works for you.
SOLUTION 6: Check Power Management Settings
If you’re still unable to access your internet connection, then you may want to check that the power management settings for your Wireless card are not set to turn off automatically in order to save power.
To verify that, right-click on the network icon from the taskbar and select “Open network and Internet settings”, On the page that pops up, click change adapter options.
Right-click on the Wi-Fi network and select properties,
Then click on configure.
Here select the power management tab and check that the option that says Allow the computer to turn off this device to save power is not checked, if it is uncheck it and hit ok. The check to see if your internet works properly again.
SOLUTION 7: Check Your IP Configurations
The last suggestion would be to check your IP configurations to see it has been reset by some application or malware. To do that go back to this network connections page below. Right-click on the Wi-Fi and select properties.
Double-click on Internet protocol version 4,
You should see the properties dialog box below.
Depending on the kind of connection you’re using you may have specific IP and DNS server addresses or have them assigned automatically, in most cases these addresses are assigned automatically, but if your connection type requires that these addresses are manually configured, then you can check with your network administrator to obtain the right addresses to enter in these fields.
