Trouble with home network

About a month ago, my home netowrk stopped working like it
used to. I can no longer see the 2 computers on it, from
each other. We have a 2 IP cable connection to the
internet, running through a 5 port switch. Both computers
can still do stuff online, they just can't go directly to
eachother. Both computers are shared with password level
access, but I have not changed a thing, they theoretically
should be fine. Any idea why this has happened and what
can fix it?

Thanks
