I'm having TP-link TL-WR740N at my home. One user is sucking 90% of bandwidth. There are 4 users of my home wifi. I've disabled pptp, ipsec. He is most probably using torrent clients like uTorrent & Bitorrent on his android cellphone. I haven't set any bandwidth control coz that user too have access to router config page. I've deleted uPNP utorrent ports set by him. Please Help. I can't even access google sometimes. I'm using a PC
