Hi guys there has been a recent problem with my home's internet. This disconnecting is very frustrating when i'm playing an online game, downloading files and connect to google and other simple tasks. We(my family) have called the company about this problem. They said it might be because of our home security system.
*we got our splitter because our phone is receiving some static or something basically we couldn't hear well through it
Here is a simple diagram of what our internet connection look like right now

You should have a filter for the line, if ADSL is the same (or works the same) as DSL. If a filter is required, it should have been furnished by your ISP.
