Testing I have done so far:
My wireless devices are an Android4.0 smartphone, Android 4.1 tablet, and Win7 laptop.
All wireless devices can see the internet and can ping all other wired devices on the network.
Wireless devices can access Windows shares and resources if I use the IP address in the path but cannot if I use the computername.
Wired devices cannot ping any wireless devices.
Wireless devices cannot ping other wireless devices.
I have not found any exceptions to these statements in my testing.
I thought this might be AP isolation, but turning this on and off in the router makes no difference.
Is there anything else I need to consider? TIA.
