I made the leap into E1.31 this year. I am using an older laptop running XP. I am running 3 2811 5m Ray Wu strips using LOR 3.8. I ran the same basic setup for Halloween minus the DMX King Micro USB. After about 23 hours the Joshua P12 stops receiving data. If I unplug and replug the cat-45 the amber activity light starts flashing again. But sometimes if I reboot the laptop the P12 server is accessible without any cable reseat. For Halloween I ran the cable through the window and since then I ran cable through the wall and installed a jack outside. Could it be a computer thing? A cable? The new jack? I may try to go through the window just for laughs? I am confused why it takes almost two days to get stuck.
