Using Wifi and LAN simultaneously in the same subnet

TobiasMT — Mon, 05 Jul 2021 18:01:39 GMT

Hi,

We have a remote site with FlexConnect and mainly Win7 devices. Last week we came across IP-adress conflicts for that scope. The Clients use the same Subnet for both NICs and they are active at the same time.

As I could not find reliable information about issues with using the same subnet on two NICs at the same time I would like to pose this question to the community.

Do you know of any interferences this setup could cause?

Thanks for your replies.

Hi there,

You will find this scenario with any home internet wifi-router.

There are plenty of times when I am both connected physically and wirelessly, with both interfaces providing my laptop with a default route. Crucially the routing table entry for the physical interface will have a lower metric to eliminate asymmetric routing.

cheers,

Seb.

- It should work, provided a single DHCP server with a single scope for that subnet. This could normally not lead to IP-address conflicts.
