Troubleshooting
In the realm of wireless communications, many factors can affect reliable data communications. This section lists a
number of known factors and possible remedies.
If your question is not adequately answered here, visit the SNAPlink support forum on the Synapse Wireless website
where you can post a question and interact with other SNAPlink users. The SNAPlink Support forum can be

Signal Strength Problems
SNAPlink adapters should communicate well when placed in near proximity of one another (as indicated by a mostly
green LED A). They might not communicate well when moved father apart (as indicated by LED A turning amber,
indicating weak signal strength, or red, indicating loss of signal). You can make several adjustments to remedy this
situation:
l
Try orienting the external antenna into different positions. Since antennas work best when they are in the
same spacial plane, essentially parallel to one another without being directly above or below each other, try to
position the antennas of all your SNAPlink devices in the same orientation.
l
There could be other interference problems in your vicinity such as large metal objects, dense foliage, or other
objects that prevent signal transmission or cause attenuation (signal loss). Microwave ovens can cause
interference problems. Try moving the units physically to another usable location to change interference paths
to see if signal strength improves.
l
Try changing the channel of each device. There are 15 separate channels (0 to 14 — channel 15 is not available
for transmissions) spread within the 2.4GHz frequency. Various other 2.4GHz devices, such as cordless
phones and WiFi routers, may be interfering with one channel, but not another one. The Portal software
mentioned above includes a Channel Analyzer tool that can help you determine which channel has the least
RF interference.
Multiple Masters
In a multipoint network, if SNAPlink devices are unable to pair with a master, check for the presence of multiple
masters.
There can be only one master in a multipoint network. If you wish to operate multiple masters within the same
vicinity, then be sure to set each master to a different channel and/or network ID using either EasySet or the DIP
switches. To reduce near-band interference, set the network channels as far apart as possible.
