youre not getting out the gateway.

try pinging the gateway from each computer, if you cannot its not home or
is now not on your subnet,
and needs to be powered down and up, or reconfigured. from the sound of it,
thats an ISP provided Router. call them. see if they can get to it remotely.

if not, and its the property of your client,
if you know what kind and model it is you can look up its default settings
which are public,
and set one of your pcs to that subnet,different last octet, and that
gateway to gain access to it,
if it had lost power and went back to its defaut settings. or else you have
to get to it physically.
