Hi,   I have two Windows 10 laptops both connected to the same Wi-Fi 4 private network in my home via an Archer VR1600v router. Both can browse the world wide web without any problems. Neither can see each other. Each replies to the other when pinged but with "Destination host unreachable"   C:\Users\peteh>ping 192.168.1.117 Pinging 192.168.1.117 with 32 bytes of data: Reply from 192.168.1.107: Destination host unreachable. Reply from 192.168.1.107: Destination host unreachable. Reply from 192.168.1.107: Destination host unreachable. Reply from 192.168.1.107: Destination host unreachable. Ping statistics for 192.168.1.117: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)   Neither of course can see each other under Network  in Windows File Explorer. Curiously I can ping the tv which is connected to the router via an ethernet cable. What's causing this bad karma?   Cheers,   Pete     ... View more
