creativevapi · Jul 4, 2015

I have 3 ALL-In-One PC with Ethernet and WiFi Controllers. OS is Windows 8.1. All 3 PC are connected with D link WiFi Router. First 2 PC are connected using Cat5e Cable to Router. 1 PC is connected via WiFi. Internet works fine. But Sharing is possible only if connect WiFi on all 3 PC. Now i do not understand this. If i disable WiFi on the PC which are connected via Ethernet Cable LAN does not work. But Internet works. I want to connect 2 PC via Ethernet and 1 Via WiFi. Can anyone Help Please ?

If internet is working on the wired PCs then it sounds like either a firewall or windows issue.

Start by working on sharing with the two wired PCs (eliminate WIFI). Verify the workgroup is the same. Verify that you can ping between them. Make sure windows file sharing is enabled. Temporarily disable the firewall.

It sounds like your wired LAN and your Wifi LAN is two different networks, using two different IP address subnets. You can check that with the command-prompt and the command; ipconfig /all

Windows firewall blocks traffic from LANs different from its own by default, and you would have to allow the specific traffic you want to send to your Windowses. (and usually every other box with a firewall)

Another aproach could be to consolidate your wired and Wifi LANs into one single LAN using one and same IP address subnet.
