After replacing a motherboard on a customer's laptop for a no sound issue, a technician realizes that there is intermittent wireless connectivity on the laptop. Which of the following should the technician perform FIRST?
Check to see if there is a wireless switch on the laptop and its current position.
Reinstall the driver of the WiFi card.
Replace the wireless card because it is not fully compatible with the new motherboard.
Check if the WiFi antenna is connected properly to the wireless card.
Because this is an intermittent issue, the problem likely lies with the wireless signal due to a problem with interference, channel settings, or the antenna itself.
Wi-Fi or WiFi(), is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide the public Internet access for mobile devices.
Wi‑Fi is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term Wi-Fi Certified to products that successfully complete interoperability certification testing. As of 2017, the Wi-Fi Alliance consisted of more than 800 companies from around the world. As of 2019, over 3.05 billion Wi-Fi enabled devices are shipped globally each year.Wi-Fi uses multiple parts of the IEEE 802 protocol family and is designed to interwork seamlessly with its wired sibling, Ethernet. Compatible devices can network through wireless access points to each other as well as to wired devices and the Internet. The different versions of Wi-Fi are specified by various IEEE 802.11 protocol standards, with the different radio technologies determining radio bands, and the maximum ranges, and speeds that may be achieved. Wi-Fi most commonly uses the 2.4 gigahertz (120 mm) UHF and 5
