My new Sony Vaio laptop is facing a Wi-Fi issue. I'm running Windows 8.1 Pro x64 and it keeps on disconnecting. The odd part is that, sometimes, it was working fine the whole day. Next day, it will act strange again. It even restart itself automatically. If you have a solution, then tell me, I'll be very thankful.
Hello,
Such problem isn’t uncommon if the Wi-Fi network frequency isn’t so strong. Also, the hardware might be troublesome, too.
First, check that your Wi-Fi network is strong enough to support good frequency. Try disabling the wireless network and enable it again from Control Panel >> Network and Internet >> Network and Sharing Center >> “Change adapter settings” on left pane. Right-click on your network, select “Disable” >> right-click and select “Enable”.
Also, there is a problem in older Sony VAIO laptops that the Wi-Fi board is faulty. Sony now provides a new and powerful Wi-Fi board with their laptops. If you’ve not opened the bottom case, your warranty should be OK. Contact to the nearest repair center for a change and they’ll add the hardware to your laptop.
Also, install the latest driver for your laptop. Download Sony laptop driver.
The most common reason why your Wi-Fi connection keeps on disconnecting, though you said you already updated the drivers of your Wi-Fi adapter to the latest version, is a weak signal. Since you are connecting via Wi-Fi, make sure the Wi-Fi signal where you are connecting to is strong. If it is weak and you still want to connect, your connection can be disconnected because of signal failure.
If your Wi-Fi connection sometimes restarts make sure your adapter is installed properly. If the Wi-Fi adapter is installed via PCI or PCI Express, uninstall the device in the Device Manager then restart the computer. The operating system should detect the device upon booting. Install the latest driver for your Wi-Fi adapter that is designed for your operating system.
If you are using the USB type, connect the Wi-Fi adapter to the USB port then uninstall the driver in the Device Manager. Next, disconnect the Wi-Fi adapter from the USB port then restart the computer. After booting, connect the Wi-Fi adapter again to the USB port then install the driver. See if the device no longer restarts.
