[SOLVED] Connect to two networks with two network cards simultaneously

[Domeen]

Hello,

I have a specific networking problem I am trying to solve. In my (Windows 10) PC I have two wired Ethernet adapters (Realtek PCIe GbE Family Controller), one on the motherboard the other in a PCIe slot.
I would like to connect one adapter to my local network and the internet using DHCP.
The other adapter is meant to connect directly to only one device (a robotic arm with a static IP on its own subnet)

Both connections work individually but not together.
Any advice how to make the two connections work together is appreciated.

Best Regards,

As long as the subnets are different it will just work. You need to remove the gateway and dns setting on the secondary nic card.

On the second adapter (connecting to the robot) - just use manual IP configuration, IP address and net mask only, no gateway, no DNS servers. You can even disable all protocols and services but IPv4.
