Hello everyone- We have had our Rock Band for about a years and this week the wireless transponder will not hold a connection with the guitar. While we are in the middle of the song it will just losse a connection and the "dongle" will begin to blink and all four of the lights on the guitar will blink. Here is what we have tried so far: * we swapped the guitars and have the same problem * changed batteries in both guitars * reset the guitars to the unit * swapped ports on the "router" All other items are working properly. I have done a search but have not had any luck. Any ideas?
