Why is the link quality or signal strength poor on my ZyXEL Communications G-202?

  Poor link quality or signal strength on your ZyXEL Communications Adapter could be due to radio interference, such as from a microwave or another access point using the same channel. To improve this: * Search for and connect to another access point with better link quality using the Site Survey screen. * Move your computer closer to the access point or peer computers within the transmission range. * Lower the output power of each access point. * Ensure not too many wireless stations are connected to a wireless network.
