So, I have two routers on my home network. The first one, Belkin F9K1001 has an IP of 10.12.5.55 / subnet 255.255.255.0. The second one, D-Link WBR-2310 A, has an IP of 10.12.5.65 with same subnet. Both routers have wifi enabled with same SSID & security. The Belkin has DHCP enabled but the D-link doesn't. I have two pcs wired to the Belkin, Circe with IP of 10.12.5.100 & Zeus with IP of 10.12.5.101. Another cord goes from the LAN (NOT WAN) to another LAN port on my D-Link. My D-Link is connected to another PC, a network printer, and bluray player (for netflix) via network cords. I have a wireless computer running windows XP that connects to the D-Link. It has an IP of 10.12.5.106. I have a laptop running Windows 8.1 that connects wirelessly also, with IP of 10.12.5.108. Neither wifi pc can be pinged from Zeus (10.12.5.101) but the Win8.1 can ping back. The WinXP cannot. Basically, I need to be able to ping all possible devices from any other possible device on my network. I can see all the computers however in the network neighborhood on all pcs and connect to share files and so forth.
My apologies for posting in the wrong forum at first. I did not see the networking forum until after I had posted this. Feel free to move this to the appropriate forum.
