Wired and Wireless Networks Have the Same MAC

Ya know, I have never looked at my router at that, now I am going to have to look.
I would think that they would have different addresses as they are different interfaces.
You can be connected to both wifi and wired at the same time so you would think that would require different mac addresses.

Wired / wireless are just access options for the same device. One discrete device = One MAC address.
It makes things much more complex for devices if you have different mac addresses.
Both wireless networks and the wired lan network are the same large subnet/broadcast domain. The router only has a single ip address on all these networks. When it receives a ARP for its ip from a client it must respond with a mac. It is much more simple if it always responds with the same one no matter which interface it is on. It could I guess use different mac for each interface but it would then have to keep track of much more data.

I did not change any MAC addresses. This is how the router came to me from Asus: One MAC address for the 2.4 GHz port and one MAC address for both the 5 GHz and the wired LAN ports. The two MAC addresses different by one digit.

Just click "Stop Tracking This Thread" above in the OP's first post, and "Unfollow" as well if that is an option..
For any who are interested:
According to Asus technical support, the wireless network (WLAN) should have its own MAC address separate from the wired network (LAN.) However, in Asus' particular implementation of this, one of the wireless networks - in my case it's the 5GHz network - shares the MAC address of the LAN.
Their engineers designed it that way for a reason, probably a very technical reason. It only matters to me that there is a reason and it's correct for this router.
