I have had the DMX bridge for over a year, but it's only been used on about half a dozen occasions. Now when I turn it on I can't see it appear in the network settings. On turning it on, after about 3 seconds the green LED flashes twice, then stays on, but that's all it does. Turning it off/on multiple times doesn't change the situation, but then maybe once in 50 power cycles it will appear. Is it just fit for the scrapyard or is there anything I can do to get it working?
