I have an ADSL modem that I use with my friend at home. I have noticed that when I block my IP address from accessing a certain website, he will also not be able to access it. The same happens when he blocks a website. Why is this? Can we have two different IP addresses to access the internet independently but using the same modem?

I have just bought Chromecast and whenever I try to enter in the four-digit code that is displayed for it to connect, it fails to recognize my Wi-Fi completely.

I do not know how or why this is happening, but I have a WiFi network stalking me everywhere I go. I have checked my phone and those around me but I cannot determine the source of the WiFi.

I have a lot of devices like laptops, tv's, phones. With  kids using the internet all day long on these. Is there a way to monitor who and what is using all the bandwith instantly?

How many WPS connections can routers do at a given time? Is it possible to do a WPS based security connection to two devices simultaneously or is the connection alternatively? How safe is the WPS over the WPA encryption method and what may be some of the demerits of one over the other? I have noticed that many still use WPA despite the easier to operate WPS security.
