unfortunately wireless controllers are not supported on the MARS.

you can add the wireless device as a generic device, as long as it supports syslog events types on port 514. The

device will come up as a "unknown reporting", but you can use the custom parser to make the most critical messages appear on the reporting.

Given below is the url to add a generic device. It says generic router but is ok
