Two devices cannot ping each other through WiFi

I have WiFi router connected to the Internet through pppoe. Router has latest version of firmware installed. I have no any antivirus software running and firewall enabled.

My router is ASUS RT-N10LX(http://www.asus.com/Networking/RTN10LX/)

My net is   : 192.168.1.0/24  
WiFi gateway: 192.168.1.1  
WiFi clients: 192.168.1.2(OS Windows 7 Professional (x32)),  
              192.168.1.3(Android 4.xx)

I have access to the Internet from any connected devices. I can ping WiFi router from any devices which have wireless connection to it. From webadmin of my WiFi router, I can see IP addresses of all devices connected to it.

I cannot do ping between devices.
I have "Destination Host Unreachable" message.

But I can do ping from my PC if it connected by cable.

I already did:

  i)netsh int ip reset resetlog.txt  
 ii)netsh winsock reset catalog 
iii)netsh -c interface ipv4 add neighbors "Network Card Name" "192.168.1.3" "xx-xx-xx-xx"

What I need to do to resolve this?

Thank you in advance for any help.)

Can you ping the devices from your router? Many routers offer a ping test tool via webinterface. Also do you have another windows/linux client to test with as this would be easier to debug. Also please include output from ipconfig /all as well as a route print – leepfrog – 2013-06-08T17:55:46.620

My router has no tool for pinging. I have no any additional OS to test. Here are listings: https://www.dropbox.com/s/ohypa91hb5pc3tz/rtprint.txt https://www.dropbox.com/s/taomj5k9bmiupul/ipconf.txt

Many wireless access points have "client isolation" enabled, which prohibits direct communication between connected devices. It's likely you just need to disable that.

My router doesn't have the "client isolation" setting, so I tried disabling the firewall instead and it worked. – Miloš Černilovský – 2017-05-28T13:23:54.940

I've already checked my access point for 'client isolation'. It's disabled. – None – 2013-06-08T17:09:41.587

I found solution. I've done factory reset for my router and issue was solved.
Thanks to all for helping.

If you are looking for that, it is in Wireless -> Professional menu as "Set AP Isolated" and I had to set it to "Yes" and "Apply" and then back to "No" and "Apply" and now it works.

That presumably depends on the exact device involved. – vonbrand – 2016-03-21T00:07:10.283
