The amp that you have is not truly an amp, just in name only. It takes the place of any splitters to prevent signal loss. It is better to find out the cause of your problems instead of adding another amp in the mix. You especially don’t want your internet service coming off an amp. Post your modem levels etc and possibly you can get pointed in the right direction
