Hy, My Inspiron 5420 is displaying problems in WiFi connectivity. My operating system is Windows 8 where the drivers are all installed. The problem is that, I get connected to a network and browse the internet,but after a certain interval of time,the internet stops working,and when I disconnect from the network and again connect to it then only it will start to work again.This happens often and its very irritating. I have tried to update drivers,but there are no positive outcomes. This is very toublesome. Please Help!!!
I would suggest you to update the BIOS and then uninstall and reinstall the Wireless card driver on the system. Please enter your service tag # on the link below, select the OS and then download the BIOS from BIOS section and then wireless card driver from Network section onto the Desktop screen.
