   Some routers let you isolate different network segments (by using   
   different network segments on each port/wifi to the router).  That is,   
   they assign a different network segment to each port/wifi connect, allow   
   outbound connects from each port/wifi connect to the Internet, but do   
   not allow traffic between the port/wifi connects.   
      
   Are all your hosts on the same network segment?  Are that all assigned   
   something like xxx.xxx.xxx.NNN where the xxx.xxx.xxx portion is the same   
   for all of them?  Is the submask for each the same?  As per Wiesers   
   suggestion, you can use ipconfig /all to see the IP address hence   
   network segment and submask assigned to the NIC(s) in each of your   
   hosts.   
      
   You also need to make sure that each of your hosts and your router are   
   supporting the same type of IP addressing.  There is IPv4 and IPv6.   
   While I had hosts that supported both, I had an old router that only   
   supported IPv4.  When I got a newer router that supported IPv6, it was   
   assigning both IPv4 and IPv6 addresses to my hosts.  IPv6 is pre-enabled   
   on Windows Vista+; however, IPv6 is not pre-enabled on Windows XP.  See:   
      
   https://www.ghacks.net/2011/02/06/how-to-enable-ipv6-on-windows-xp/   
      
   With a router that supports both, your hosts should have both types of   
   IP addresses assigned but you need to make sure they are within the same   
   network segment and that your router is not isolating traffic between   
   its ports/wifi connections.
