Hi buzz4_nt,
May I know did the wireless network work in Safemode with networking?
Check if the wireless card is enabled in BIOS. Restart the computer and tap F2 at Dell logo. Under “Wireless” select “Internal Wi-Fi” and ensure the wireless card is “Enabled”
If the issue persists, kindly private message me the service tag of the computer. To private message the service tag click my User name and click Start conversation.
Awaiting your response!
