Computer manufacturers make different laptops and PCs. Some of the popular laptops are the 15R Inspiron series and the HP Ultrabook series that have been built for performance and durability. However, there is a common problem with these laptops where the Wi-Fi does not seem to function with the expected reliability and dependency. Many users have complained of their laptop terminating the Wi-Fi connection on several but irregular occasions. After a few hours with the Wi-Fi functioning normally, a yellow exclamation appears on the Wi-Fi connection in the system tray and a connection failure follows. The internet connection is lost, and when the user tries to reconnect to the wireless network, they find that it is no longer visible. This leaves many users baffled; forcing them to restart their laptop or hard reset their Wi-Fi card (switch it off and on again) in order to be able to find a wireless connection. This only solves the problem temporary, because for sure the problem arises again after a few hours. This article will explain why you might be having this problem and how to fix it.
Why your PC keeps dropping your wireless connection
The mentioned symptoms can be caused by hardware or driver issues. If the drivers are not fully compatible with your device or operating system, you are likely to experience some issues. In this case, it is likely that your computer sends your wireless card to sleep when it is not in use in order to save on battery. However, the device is not able to wake up when needed possibly because of the driver issue. A great way to troubleshoot is to try your computer on another network or try another computer on the same network. If the issue persists in both cases, then the issue is with the computer or with your router or ISP respectively. You can use the network diagnostic tool in your laptop to further diagnose the problem. Simply type “network diagnostic” in the start menu and click on “Identify and fix network issues.” Below are some of the solutions to this problem.
Method 1: Download and install updated drivers
Using the device manager to update your drivers might in this case may indicate that your drivers are up to date. This is because Windows takes the liberty to suggest what is best for you. To manually update your drivers:
- Visit your manufacturer’s website. For Dell, you can go here to download your drivers. HP users can go here. Scroll down to the drivers section and download the drivers that suit your device and operating system. Download the drivers, double click on the download and install the drivers.
- If you don’t know which drivers you need, you can go to the download centre here and have the online service automatically detect your PC. Click on get started, install the detection software and let the system find your drivers. You can then download and install them. HP and Dell and Lenovo also offer automatic system detection on their driver download pages.
Method 2: Don’t allow Windows to turn off your Wireless Device
By not going to sleep mode, your wireless device will continue to work throughout. Make sure that your computer is not overheating in any way since this can lead to the same symptoms.
- Press Windows Key + R to open Run
- Type devmgmt.msc and hit enter to open the device manager window
- Go to the “Network Adapters” section and expand it
- Right Click on your wireless device and then click on “properties.” Note that if your device has a yellow triangle with an exclamation, then your drivers are definitely the issue.
- In the properties window, click on the ‘Power Management’ tab
- Uncheck the “Allow the computer to turn off this device to save power” option. Click OK and check if the problem persists.
Method 3: Reconfigure your Wireless Adapter
By changing the channel frequency range detection to auto, you will be able to escape the hurdle caused by non-conventional frequency ranges used for Wi-Fi connection in different countries.
- Press Windows Key + R to open Run
- Type ncpa.cpl and hit enter to open the network adapters window
- Right click on Wi-Fi adapter and select properties
- Click on configure
- Go to advanced tab and look for the property: 802.11n Value and the 20/40 coexistence. Change both values to Auto
Make sure that your router is getting enough power and the plug and 12/5V jack is connected properly. Also keep it away from the interference from electrical machines like coffee makers and microwaves which interfere with the Wi-Fi waves.
