Hi...
I have a problem.
Made an automatic connection to my neighbors wifi router (with consent of course) and it work OK first time. But the moment I shut down my computer then turned it on it started connecting and disconnecting for dozen times before it established normal connection. It happens when computer turns on, wakes from sleep mode, and lately on random when browsing web. I turned off setting in power management to allow adapter to be turned off by computer.
Its a standard desktop computer, running Win 7.
What could be the problem and what can i do to make it work normal?

Thank you in advance.
