I have a lenovo laptop and a desktop as well. The wifi is working fine, the desktop is currently running on it. the laptop was working until today. it wont connect to wife, when I hit the link show the avail networks, it wont any of them including our own. Not sure how to to connect, it generally connects automatically when we get home from being somewhere else and using another network. Any Suggestions?
Most laptops have an on-off for the wireless. Control varies - might be a key combo like Fn-F2, might be a physical switch on the side of the case, might be a wireless utility. Check that first.
Also check the device manager to make sure Windows is happy with the wireless adapter driver and that the device is activated.
