I have 2 PCs that are both connected to the same WiFi network. Both PCs are on the same work network, both have the same workgroup name and I have toggled network sharing off and on - on both of the devices.
Neither can ping the other. However, where it gets strange here... If I run simultaneous cmd pings of each other, #1 PC starts successfully pinging the other, but stops if I stop the ping attempts from the other PC to it. #2 PC pings never resolve.
Both devices are Dell Optiplex 3030AIO and on Windows 7 Pro, Service Pack 1
