windows 8 PC's cannot see/ping/talk to each other

Hello ALL,

I have two Windows 8.1 machines on my network, they are not Pro so I can't join them to my domain, the machines cannot ping or see each other on the network.
I have modified the Windows Firewall every way I know how and they still cannot talk. Opened ICMP traffic, uninstalled McAfee.
My server can both machines, my Windows 7 PC can see them, but they can't see each other. Pings fail with destination host unreachable.
Both machines are in the same workgroup.
Any tricks to get them to talk to each other?
Any help would be appreciated.

The issue was with the wireless router. AP isolation was turned on so the wireless clients could not see each other.

Don't just modify the Windows firewall - DISABLE it.  Can they talk then?
Brandon GreenAuthor Commented:
Yes I disabled it and that didn't work, same error.

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

With the firewall disabled, can those systems ping other systems - ANY other systems?  

Are your sure your IP, Gateway and Subnet Mask are correct.
How did you disable it, did you turn it off, or stop the firewall service? Don't stop the service.
