RAX80 is supposed to be backward compatible with other 802.11 (b/g/n) standards, but isn't

Nope.  Netgear cuts you off after 90 days unless you pay exorbitant support fees.  No thanks.  I just access those computers using a wifi hotspot from my phone, which is backward compatible and does work.

I saw a "solution" online.  "Turn of AX mode" by unchecking the ax mode box in the router configuration.  Really?  People buy a $400 wifi 6 modem that's supposed to be backward compatible with anything 802.11 b/g/n and it doesn't work, so Netgear's only solution is to turn off wifi 6 mode?  Isn't that the equivalent of buying a modern gaming laptop so you can play DOS Pong on it?  I'm not about to do that.  I paid big bucks for that speed and multiplexing ability and I'm not about to accept that as a solution.  That's utter baloney.

I have spoken to tech support at length multiple times and they have failed to figure out the problem that seems to be the same as this post.

I have 12+ devices that ALL see the new router, but my older Win8 machine does NOT see the RAX ssid's.   That specific computer DOES see every other wifi in my neighborhood, but not the amazing and powerful RAX80 (which is 30 feet from it... And i'm picking up dozens of wifi signals on that box from hundreds of feet away).

It seems as if this thing cannot act compatible with older Network Interface Cards (older 802.11 standards) while also standing in it's own power and rocking on newer devices with newer standards.

Can anyone confirm if it is compatible simultaneously with newer and older standards?  (If so, the resolution to my issue is to be found elsewhere).

Thanks
