We are having difficulty with the Internet lagging lately, we have a very large household and many devices connected to the wifi. however the most problems are seen when the following are connected 2 kids playing PlayStation online games, 1 Xbox playing online and an iPad streaming video content via you tube or Netflix. as well as a few phones or iPads iPads just doing basic i functions. this cause the PlayStation to lag according to the kids and they make the iPad or Xbox get turned off to fix the problem. I am not sure what the problem is and really is frustrating ti listen to kids fight over Internet daily. I currently have broadband 50 and a Cisco DPC 3825 modem. Please help me fix this problem.
