R9000 two different MAC addresses!

[Ra-Dzik]

And another one "flower" in Nighthawk X10 R9000 - two different MAC addresses!

The first one I have on cartoon-box on sticker it is "XX:XX:XX:XX:XX:BF" and the other is in configuration of my firmware "XX:XX:XX:XX:XX:BE" - the last letter is wrong.

BE CAREFULL IF YOUR ISP NEED MAC ADDRES FOR AUTENTICATION TO CONNECT TO THE INTERNET!

I don't recommend this router Nighthawk X10 R9000! Too many bugs, too much lost time, too many lost nerves, too many lost money, No feedback from Netgear, no new firmware. Stalemate situation.

I started procedure to return R9000 to the shop and I want to give my money back!

Don't buy Netgear Nighthawk X10 R9000 router!!! Definetely not recommended!

   A router has more than one interface.  Each interface can (must?)
have its own MAC address.

   "Different" and "wrong" are spelled differently for a reason.  Where,
exactly, did you find this other MAC address?  (Hint: "in configuration
of my firmware" is not a useful description of a location.)

   For example, on my D7000 (V1.0.1.66_1.0.1), ADVANCED > ADVANCED Home
: Router Information shows the MAC address of the LAN interface as
"50:6A:03:E9:AE:86", and the Internet Port section shows the MAC address
of the WAN interface as "50:6A:03:E9:AE:87".  Which is "wrong"?

   Yes.  Be sure to provide the MAC address for the WAN/Internet
interface, which is almost certainly the MAC address on the box.

> I don't recommend this router Nighthawk X10 R9000! [...]

  And perhaps you have good reasons, but "two different MAC addresses"
is not one.  (And what does this misguided rant might say about the
value of your other complaints?)

Greetings @Ra-Dzik

While I won't dispute with you that there are some performance issues with the current versions of FW available for the X10, your criticism regarding the MAC addresses is unfounded.  It's not a bug or problem. 

Each network interface wired or wireless, gets a unique MAC address.  The router has one of its own as well.  The MAC on the bottom of the router is for the LAN.  The WAN is typically one octet higher.

There is nothing to "BE CAREFUL ABOUT".  This is intentional and is standard network implemetation.  Each interface gets a unique MAC address.     

And @antinode gets a thumbs up for his reply!!! / @schumaku too!

On Ethernet routers the MAC address on the box, the label, is commonly the one on the LAN interface.

Have an eye on the Advanced Home - just one click away from the default Basic Home - would have unveiled the MAC address used on the Internet/WAN port, , here the LAN is :11 (as on the box and the label), :12 the Internet/WAN:

And of course (almost) all interfaces have their own MAC address: LAN, Internet/WAN, 2.4 GHz Radio*, the 5 GHz radio BSSID, the 60 GHz radio BSSID, the 2.4 GHz Radio Guest network BSSID**, the 5 GHz Guest network BSSID**. 
 
*interestingly mapped to the LAN MAC, too.
**transcoded MAC based on the radio BSSID.

Of course, Netgear could do better markings on the box and the label. Said that - a typical rant by an unhappy user - easy to proof that the appropriate information is easily discoverable in the Web management, in the Nightawk App for the relevant LAN and Internet/WAN interfaces, and on the Genie App Network Map for the WAN interface.
