i have this fked up sis who tinks she owns the internet in the house.. currently like downloading a million things in her laptop and maybe sending her frens some stuff, while sucking up all the bandwidth. she tink she own the internet? my internet here is now fkin slow and check out my CS best latency (when she did not use laptop, best was 10+)

also went to speedtest.net, my download spd was like 70+? wtf?
without ehr using laptop, was like maybe 4k?
can any1 teach me how tpo limit bandwidth to other com and give me more? that would teach her a lesson
