Pretty simple problem, but weird.  I replaced today my Archer C2300 (it simply stopped putting out a wifi signal even though it said it did) with a AXE 5400 / AXE75.  I used the same name of the network and pw so all my devices would simply reconnect, which all seem to have done except my laptop.  It's connected now to an old extendere which picked up the new router just fine, but it does not show the new networks at all.  Like, the names don't appear as networks.  I'm still showing the two extenders and my neighbors, but not the new bands with the same names as before.

I restarted a couple times.  No change

Command lined: ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh winsock reset
netsh interface ipv4 reset
netsh interface ipv6 reset
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log

Restart.  Same problem.

Troubleshoot, nothing that made it magically appear as a network to connect to.

"Forgot" the old network name, hoping it'd show back up with the new router.  Nope.

What am I missing? 

Any help would be appreciated.  While I at least can connect to the extender, it's not as fast, obviously.
