I keep searching the internet to find people having the same problems as me with WaveBird (GameCube) controllers, but it seems like I'm all on my own. Sorry about the long post, but I've tried to show everything I've already tried to eliminate the obvious suggestions. I'd really appreciate any advice though. I have 4 WaveBirds. All 4 receivers are permanently plugged in and I sit 10-15 feet away from the console. I've noticed the problem when using just a single controller, but haven't spent enough time with multiplay to comment on this. Basically, after a variable period of playing, the controller starts to have occasional "dropouts" in that the signals from it do not get received. If I'm pushing the stick to move, my character will stop & the light on the receiver will go out. This dropout will continue indefinately if I continue to hold the button/stick & keep the controller in the same position. If I reselect a button/stick position, or move the controller, the light will come back on & all will be OK again. I have tried the following with no success: Replace batteries (same prob. with various new Alkalines) Swapped controller and receiver - same problem Tried different channel number - same problem Different sequence of channels (e.g. 1,4, 7, 11 instead of 1,2,3,4) - no difference Raised the GameCube from floor height to about 4'. Hard to say, but this seems to have given a slight improvement. I can't believe that both Wavebird/receiver combinations I tried are faulty, when these seem to have such a good success rate, so I must be doing something wrong........... Is it possible that the 20 foot range is over-optimistic, and I'm really near the useable limit? Any other suggestions very gratefuly received.
