Incorrect MAC Addresses being shown on Netgear R7800 router

Hi

 

I have noticed connected devices to my wifi network (Mac addresses of each device) don't display the same MAC address when viewing on the "Access Control" page within Router Administration program.

 

But it seems that if I view the "View list of allowed devices not currently connected to the network" devices

the correct MAC address(es) are displayed. (even though these devices ARE connected to the network)

 

Can anyone tell me why this is happening?

 

If I turn off "Internet" or "Block" the device in question from the device list (currently connected to the wifi network) this being the wrongly displayed WIFI MAC Address (it does block the device in questionfrom getting out to the web).....So why is it showing a different MAC Address to the one that is ACTUALLY the MAC Address for the device?

 

The only thing I can think of is that I do have a Netgear Extender upstairs....could this be causing the mismatch in MAC Addresses?

 

Any thoughts would be great..

The whole point of this exercise is to correctly identify the right MAC Addresses to the right Devices (and label them) so it is easier to troubleshoot individual devices if there's an issue.

 

Current firmware version is latest (V1.0.2.80)

 

Regards

Ken

   It's part of extender operation.  See, for example:

 

      https://kb.netgear.com/24806

 

   A Web search for terms like, say:

 

      wireless extender spoof mac address

 

might be educational.

Re: Incorrect MAC Addresses being shown on Netgear R7800 router

I have taken the extender out of the equation now.......as it's not really needed....reset the extender to factory defaults unplugged it..

rebooted router, powered off my iphone (which was one of the devices showing the spoofed MAC address).

once turned on I was expecting my iphone to report into the router the correct wifi MAC address but it still has the spoofed (Extender address)....Umm

Even more puzzled now....removed all devices from the "View list of allowed devices not currently connected to the network" list

which included my spoofed MAC address for my iphone (when the extender was in play)

Turned off iphone, refreshed router Access Control page - device disappeared from the Allowed Connected list, and went into the

"View list of allowed devices not currently connected to the network" list.

Turned off iphone again and back on and now another MAC address (which is different again!!) has appeared in the Allowed Connected list.

and it's not the REAL iphone Wifi MAC address!!

   Define "real".

Re: Incorrect MAC Addresses being shown on Netgear R7800 router

I have just been setting up a Netgear RAX80 router, and when I look at Attached Devices, the MAC addresses are all wrong. I want to force specific IP addresses for various devices - which MAC address should I use?  The correct ones or Netgear's weird ones??

 

For the avoidance of doubt, my definition of "correct" is the MAC address shown in the device, which also displays correctly on my Netgear R7800 at a different location.

   Ok.  Are you using a wireless extender as was the fellow who opened
this thread? Are you using an Apple iOS device?  Why did you join this
thread instead of starting your own?

 

> [...] the MAC addresses are all wrong. [...]

 

   I can't see them from here.  Which kind of "all wrong"?  Wired or
wireless devices?  Always the same MAC address for a particular device
on a particular router?

 

> [...] I want to force specific IP addresses for various devices -
> which MAC address should I use? [...]

 

   The router sees what the router sees.  Which one works?

 

> [...] displays correctly on my Netgear R7800 at a different location.


   Apple's "private Wi-Fi address" feature is specific to "each Wi-Fi
network."  Without more information than "I'm unhappy", it's tough to
guess what's causing what you (only) are seeing.

It would be useful if someone helpful could reply, not someone (purporting to be a guru!) who just wishes to pick at the content of a question to prove how clever he/she is.

   The forum software determines those ranks, not the participants.  I
purport nothing.

 

   Also helpful would be starting your own thread for your own problem,
and including some useful information in it.  In any case, answering
those pesky questions would be more helpful than all the indignation you
can muster.

 

   Appending your query to a thread which has been marked "Solved!"
might not be the best way to attract the attention of other
participants.  Unless, that is, you're depending on psychics.  I suppose
that if they're good enough to find your information-free problem
description, then they might not need more information from you.

   Hey.  They're _helping_ you.  On the bright side, if you don't want
the greater privacy, then you can disable the feature.
