How to Fix a Flashing Red Light on a Wireless Network Adapter
A wireless network adapter is a device that receives an Internet signal and then routes it wirelessly to any devices that are within range of connecting to it. If you have an adapter like this in your home, you will be familiar with the dazzling array of lights that blink into life when it is working or booting up. You may also have noticed that occasionally there is a persistent flashing or blinking red light that doesn't cease, even when your adapter is not performing any tasks.

Reconnect the power to the adapter, followed by each of the devices one at a time. The flashing light may have resulted from a failure during diagnostic checks at startup, so resetting the device may correct the problem.
