Weird problems on my network! Please help me out

[Dennis_44]

Hi, i hope someone in here can help me out..

my problem is following:

I can ping/access using IP-Address:
Wireless device -> ethernet device
ethernet device -> Wireless device

i can't ping/access using IP-Address:
Wireless device -> Wireless device.

From my ASUS RT-AC87U router i can ping everyone..
I looked in the arp table, and these pc i can't ping isn't there.

last time i tried was from windows 7 -> windows 10. Recently my windows 7 has update to win 10, cause of mircosoft autoupdate -.- But it should not be the problem. does anyone have an idea, what it could be?
For the note, i have a good knowledge to IT, but this is weird in my eyes

Thanks!

Well i found out that, in my Wi-Fi setting(Professional tab) there is something called: “Set AP Isolated“ which make wireless devices unable to communicate.. So i just disabled that security feature, then it work 🙂

Make sure all computers are on 'home network' and are in the same workgroup.
