Announcing ConnMan.net

So is your driver bouncing around and unable to hold a stable connection? Is the access point and network randomly failing to reassociate? What driver do you have? Can you provide some logs from /var/log/messages or /var/log/daemon.log that show the problem so we can diagnose it?

The "second time problem" is almost always a case of driver bugs or supplicant bugs. If you can connect again after you 'killall -TERM wpa_supplicant' or 'rmmod <your driver>', then you've found the source of your problem, and that's where it should be fixed.
