unraid 6.7 support 4 lan port network card? After I put the network card, it said too many devices.  

 

how can I fit the problem?

 

 

Does too many device means storage instead network device, what licence and how many storage device in your system.

Unraid counts attached drives during boot. It doesn't count network ports. Having USB drives attached during boot will cause this.

Solution, unplug them at boot time.

Technically this is just before starting the array, so it can happen at times other than boot time if you ever stop the array.

But to answer the questions yes it can support 4 port lan NIC's
