Im new to all this & I've been having problems with my wi-fi dropping connection or just being really slow. My ISP which is AT&T told me about this site to test my speed. I'm using my iPhone 4s to run test, I don't have a computer or tablet. I also use my wi-fi for my DirecTV & 2 iPods & another cell phone. According to my ISP I have the fastest internet package they offer. I would like to know what "download speed test" & "upload speed test" mean? I run download speed test periodically throughout the day & during the day I always get the result of 2 or higher but after midnight I get results of 1.6 or lower. Why is it that during the day my speed is fine but at night it's not? Sorry for the long post but I'm desperate for any advice.
