Today, I encountered a problem. A Lenovo laptop with the k43g Model Turned on the wireless Nic switch, but the power indicator of the wireless Nic was not on, just as the hardware of the wireless Nic was damaged.
View "Device Manager". The wireless network adapter is displayed under "network adapter. This is the second time I encountered this kind of notebook. Of course, the first time I thought my laptop was broken, I made a warranty call, and the second time I encountered this problem, I was already familiar with it. Now we will record the solution to this problem to avoid forgetting it.
Step 1: reinstall the k43g power driver. (It's strange that it's not a wireless NIC driver, but a power driver, but it does );
Step 2: Enable the wireless Nic;
Step 3: Press FN + F5 at the same time. The wireless Nic control page is displayed;
Step 4: Select enable wireless network card;
Solve the problem !!
