I've had this happen before and normally it just fixes itself but I've left it off for more than an hour and nothing has fixed. Basically, my wireless controllers don't connect to the console when I hold the Xbox button. My wired controller also doesn't work. When I press the sync button, it clicks but the logo doesn't flash. I've tried unplugging the Kinect/all usb accessories and that didn't work. I've followed heaps of tutorials to fix this but to no avail. I tried to find out how to hard reset with the power button but all the methods I tried didn't work. It's worth noting that I've had wifi issues before so I've had to use Ethernet, and one of my theories is that my wifi card is on its way out but apart from that I've tried
everything possible, how do I fix this?
Update: Since I had this issue, I unplugged my Xbox and all usb cables/Kinect and left it off for one night. That seemed to fix it for one day, but the next day it started having the same issue again. Can anyone help me find a better temporary fix (Or better yet, a permanent fix) for this issue?
