Network Controller - Yellow exclamation mark

[User38]

My HP all-in-one PC crashed and has now been repaired and Windows 7 has been reinstaled, but it is not connecting to wireless internet. It connects to the internet through a LAN cable though. In the device manager window, there is a yellow exclamation mark under Network Controller. Which driver do I need to install to fix this? Or is there something else that needs to be done?

Hi:

You need this driver for the model wifi adapter your PC has...

This package contains the driver installation package for the Ralink wireless LAN Controllers in the supported  models running a supported operating system.

Thank you for your reply! Will this work for Realtek PCIe FE Family Controller as well?

You're very welcome.

The driver I posted will only install the Network Controller - Yellow exclamation mark device, which is the wifi adapter that needs a driver.

If you are seeing a Realtek PCIe FE Family Controller, then the driver for that is installed and the ethernet should be working if you connect via an ethernet cable.

Thank you SO much! It worked 🙂 The PC is now connecting to Wifi.
