Elias, im being serious here, not trolling..
have you had heavy rain there recently, or is it raining or storming atm?
i had it the other day first time ever, it was storming on and off. (stopped after the storms finished so im assuming it was disturbance cause of the rain)
also try rebooting modem & router, disconnecting every point (even wall) and plugging them back in after about a minute.
