Search and connect to another AP with a better link quality using the Site Survey
screen.
Move your computer closer to the AP or the peer computer(s) within the
transmission range.
There may be too much radio interference (for example microwave or another AP
using the same channel) around your wireless network. Lower the output power of
each AP.
Make sure there are not too many wireless stations connected to a wireless
network.
