here's a weird one I get. If I have, say 4 devices on my network, doesn't matter if hard wired or on wifi, and one gets turned off during DCS, I lose my TIR in game (TIR unplugged message). As soon as that device reconnects to the network, my TIR will come back on (TIR plugged in message). It only happens during DCS, my other sim titles don't do this.
I noticed it when my lady turned off my home theater receiver and I lost the TIR. I told her to turn it back on, and TIR came back on. Also, if I Start DCS and it doesn't recognize my TIR, i'll just go over and turn on the receiver and then i'll get the (TIR plugged in) message in DCS. My receiver is on my network via CAT5.
