The first thing I would do is monitor the network usage on your sisters computer when its running. You can do this by going to Windows Task Manager (Ctrl+Alt_Del) and clicking on the Network tab on a windows PC or using Activity Monitor on a Mac.

i went to look for rogue or any program that would suck up bandwith in background and i did not find anithing suspicious .
and yes my sister do skype teamspeak alot .

so i went into my router and i did enable bandwith control :egress bandwith (512 kbps) and ingress (2048 kbps) and i think that may have solve the problem , 2 days now with no lag , so far so good i think
