Something happened to my internet sharing

i had two computers sharing the internet, this one is the host, mine is the client. before i went to work, my connection was fine, both computer were online. but when i got back, my client comp couldnt connect. i pinged both computers back and forth but i cant get a response. all it says is "request timed out" does anyone know what the problem is? im using cable modem with a router. i havent changed anything at all. its the same as it was when it worked earlier. im really mad.

i would try checking connections or resetting the router.

of course like 5 seconds after i post it starts working...thanks anyway i did try that btw lol

Log into your router via the web and see what's up if it happens again. :)
