And it's showing. Now I would be guessing you are looking for a WiFi adapter but this is me guessing. I could guess badly but here goes.
On many PCs we have to install not only drivers but APPS specific to the laptop or PC to turn on the WiFi adapter. This can elude folk new to installing Windows.
i have Acer aspire 5745G
In Device Manager === network adapter i have just " Broadcom NetLink (TM) Gigabit Ethernet "
What's the problem !!
