network driver

HI:

I received your flash drive today but I am having trouble resolving my problem. I seem to have deleted the network drive while installing win 10, so I can't get on to the internet or wifi. I have tried several things and no luck.
Several things I have found is no driver for netwok driver, broadcom network adapter 802.11 drive is empty, generic SDIO, no driver or is empty and SD\VID_02D4&PID_4328 could not be found. Some of this Information I found with your flash drive but no luck resolving the issue or issues. Can you please help ??
