I am using residential timewarner cable internet get wifi through a one piece router / modem so timewarner controls the internet. I could use a separate router but have noticed that the internet disconnects and I am forced to reboot many times. When timewarner cable company has control of the device; internet disconnects less. I have many visitors in my house so I would like to monitor their internet but due to my setup there is no login screen only a wifi username password. So this may be harder to do than public internet at Starbucks where there is at least a login screen. I have done wireshark tutorials and all I can see is my traffic. Is netcrack good? Also because I am supplying the internet I can create a wifi hotspot for my household.
