I have a wireless broadband connection from Tikona. I have connected the same to TP link router WR740N so that I can wirelessly connect all my phones and computers I have. The connection I have is a 4 MBPS connection.
The connection works well, and the speed in speed test will always show around 4 MBPS until I connect a phone that I own. As soon as I connect a samsang S3 phone, there is a drop in speed in all computers that are connected at that point of time. When I do speed test I can only see 50% speed. Once I disconnect this phone, the speed goes back to 4 MBPS. I know that there is some problem in this phone. But I have checked if there is any backgroud app that is using the internet but there is nothing. Getting puzzled with this issue. need help..
