I want to be able to connect to a closed network through LAN but to also have the WiFi open for internet. To connect to the closed network I need to set a static IP on the Ethernet card and to have Internet through WiFi I need to leave it as automatic IP. If I close the WiFi connection I am able to ping and RDP computers on the closed network but when WiFi is on I can't, but I do have internet connectivity. I've tested this on a laptop with Windows 10 and on one with Windows 7 (both Pro versions) and they are both unable to do this. Is there any way to make this work?

This is the route table with WiFi off:

Thank you, Liron Hallak

  • Show WiFi interface settings (IP-mask-gateway) and the same parameters You set to NIC interface. Show route print output with (no Inet) and without (Inet accessable) of setting NIC parameters. PS. I think the problem source is You try to set default gateway on the NIC interface - it's wrong, You must set route to LAN subnets only. Or maybe subnets of NIC and WiFi intersects - if so, we need much more info about You networks for to help You...

  • The problem is that when WiFi and LAN are connected I do have internet but I can't access other computers on the network. The settings I have for the WiFi connection are all automatic, so it depends on the network I'm connecting to. I connected to my phones hotspot and to my office WiFi with no difference in the results. The settings on LAN are without DNS, I set a static IP and gateway.

  • Show any WiFi connection settings and route table when this connection is on (no LAN) and off (LAN accessible). Add it to Q. text.

  • I can't post print screens of network settings because this is sensitive material. How do I send route prints without reviling the static ip's?

  • I can't post print screens of network settings because this is sensitive material. 1) Do not post "print screen", post console route print command output (copy-paste); 2) Replace real addresses with some like "11.22.33.44" keep subnetting with accuracy (if exists). Private addresses do not need in replace.
