Internet Quality Drop and Random Internet Disabling
Recently, my dad had a phone call with AT&T over why our internet was down. They picked up and while he dealt with the problem, AT&T was asking him to upgrade to U-Verse or the new Fiber Optic of our area but he eventually won out and was allowed to keep our standard internet and a new motem in order for their all Fiber Optic area. The next follwing days, our internet quality had dropped. For example, I can't play games like League of Legends without a 120 ping/lag(close to a disconnect) over the previous 70-80 ping(average).
And randomly, our internet will "disable" itself. I don't have the right word for it, but at random times, I become incapable of using my internet. A page shows up saying that for some reason, my laptop can't connect to the internet. But, when I look at my Wireless Networks window, it clearly says I'm connected to our wireless internet and everything is a-okay. I have attempted waiting on it and just refreshing it, but I get the same result. The only solution appears to be restarting my motem(numerous times) in hopes that it will start working again. Afterwards, the internet is working again, but with poor quality.
I would kindly enjoy any help or experience any of you have had before with this problem so we can figure out a solution to the problem.
