Netgear has set up a community forum specifically for General Router products. Most of the people who watch that forum are more likely to have experience with older routers and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

You don't say what these devices are.

 

Some wifi like to change their MAC address, ostensibly for security reasons.

 

New 'Private Address' iPhone feature could severely impact the Wi-Fi industry, expert says - Wi-Fi NOW Global

 

Then there are things that can have more than one MAC address. (Wired and wifi, for example.)

 

If you want to investigate further, do an Internet search for the MAC address. It will tell you who made the thing.

There is absolutely no need to post your message anywhere else. The question you pose applies to just about every router going.

 

As it is, the difference between your router and the standard Nighthawk devices is probably just the price. They are a bit more expensive with extra bells and whistles. They often look the same.

 

Repeating your message elsewhere is just a pointless and unconstructive waste of time. It also clutters up the place.

 

If you do have a question that relates to your router, by all means use the section dedicated to your hardware.
