Wireless controllers wont work lights just keep flashing

THE LIGHT WONT COME ON ON THE DONGLE THING. IV LOST THE INSTRUCTIONS AND DONT KNOW WHERE TO START. IT DOSENT GET MUCH WORSE THAN THAT DOES IT.

Go to:
Start/Control Panel/Network Connections and right click on Wireless Connections then left click on Repair
This works sometime. Also you might want to restart your modem as well as your computer to get everything in sync.

i just sync both of mine to my ps3 it was giving me difficult at first, but i noticed the when u first put in ur usb wireless thing it starts to blink really fast and when u push the p3 button on the controller twice it flashes really fast. so i took out the wireless usb thing then put it back in so the light on it would be flashing really fast like it was searching for somthing, then press the p3 button twice to make the lights flash really fast aswell so it will sync with it. Thats how i got both of my controllers synced we my ps3. the lights on on the wireless usb thing and the controller lights must be flashing fast at the same time to sync.

If the light on the controller is flashing then the batteries are still good. There is a small reset button on the receiver that came with the controller. use a needle to reset it while it is still in the ps2. make sure that the ps2 is turned on and the green light is flashing on it. it should blink a few times and then the light on the controller should turn red. once it does then press start and your good to go.
Hope this helps!

if this for xbox 360 elite or just regular, your wireless controller need a good battery, Once you replace the battery. Connect the wireless controller on your xbox closely and go the sub menu of xbox 360 to check the configuration for wireless.

I had the excact same problem with a Microsoft wireless controller. It just showed it synced fine and the controller dropper off the rig right after, keeping blinking idly as always when unconnected.

Solution: When you power the console on with the X button on the controller, try pressing the connect button on the controller then, apparently the console looks for controllers when it's just opening the user interface. Had to try it twice but it synced fine just as I was giving up hope, and has been working ever since!

you have to use a rechargeable battery pack,for some reason those blue controllers and the legendary need the packs or they wont work right regular batterys dont do it even new lithiums wont work.

have you tried to pair it... the little white button on both the controller and the 360? works just like the wii remote

if its wireless then it might be...well i dont know but if its wired then the cords could have streched out

I dont know if you have been able to figure out what the proble was with your 360, but the exact SAME thing happened to me. The 360 seems to be working fine, game loads, and both the consoles and the controllers rings lit up green, but then the controllers ring just keeps flashing and the console won't recognize it. I 've tried other controllers and nothing worked and obviously I tried to synch it with the console time and time again. PLEASE HELP!!!
