I have DELL Latitude E5520(early 2011) laptop. I have formatted it due to virus problems. After that i am not able to connect to wifi - internet(BSNL broadband internet at home). What are the drivers to be installed and how it is to be done. ?
Please punch in the system service tag or express service code from the link below. Then Click on System configuration tab and then Click on Components and find the wireless card of the system and then download the wireless card driver found under Network section and also Broadcom Ethernet Driver.
