Table 21 Troubleshooting Link Quality
PROBLEM CORRECTIVE ACTION
The link quality
and/or signal
strength is poor all
the time.
In wireless station mode, 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 wireless client(s).
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.
Ensure there are not too many wireless stations connected to a wireless network.
