I have a problem with my home network that I have managed to narrow down a bit, but I'm not sure what to check next.
The network behaves just fine, until my wife also connect via WiFi (I'm also connected via WiFi by the way).
When she connects everything start getting slow. When I play games, I get a mad lag. When pinging my server, the ping time goes from ~20ms to ~350ms.
When my wife turns her computer off, the net works fast for me again.
She off course complains that the net is always slow.
So that means that the problem is on her machine I guess.
So what I want to know is if it's any way to see which programs use what portion of bandwidth? It would probably be necessary to know if any "hidden programs" like malware or viruses use the bandwidth as well since I guess that is a likely scenario in this case.
Any help in this case would be appreciated.
