Recently my PS3, which has been very stable since Christmas until about a week ago, started losing it's connection to my Siaxsis Bluetooth controllers. I have to plug it in with the 6" USB cable to get it to re-connect and then I have to keep it plugged in or else it just won't work. Trying to turn on the second controller when this happens is no use, as the 4 lights on top of the controller just flash and it never connects. Any suggestions as to correcting this issue or what may be causing it? Thank you.
