By performing some administrative best practices and preventative maintenance, you can prevent many 
problems with your system, or become aware of minor problems before they become serious ones. 

Wi-LAN recommends the following practices.

•

Maintain the integrity of the system design when adding or changing a system. The introduction of 
new elements to a system can cause problems unless the network plan is revised to take into account 
the changes. For example, improper installation of a co-located antenna can add unwanted system 
interference.

•

Measure and document system performance at the time of the original installation.

•

Monitor system performance regularly. Environmental change as well as normal wear and tear on 
components can affect system performance.

•

Perform preventative maintenance every 6 months. See 

28 for information.

•

After periods of extreme weather, perform link monitor tests to verify the system; inspect towers, 
antennas, cables and connectors for damage.

•

Change menu passwords so that only key personnel can reconfigure the system. See 

•

Keep records of recent changes. Especially document the addition of units, hardware and software 
changes and changes to configuration settings. Configuration errors often cause other problems. 
Current records can be compared with original installation records and function as a benchmark to 
help you troubleshoot.

•

Keep a log of past and present problems and solutions. Store the log on-site, if possible. The log 
identifies common failure points and fixes.

•

Before contacting Wi-LAN for customer support, document the symptoms of the problem and the 
steps taken to diagnose and fix the problem. Record the current configuration of the system.
