None of my devices connected to my network are seeing any of the other devices.
File sharing is on.

The router says "AC1900" on the front, but the info on the back says Archer A9, and I get firmware up to date.
The renaming is the only thing I did. The IP addresses are distinct. Only the new iMac is hardwired. The other two computers are connected via WiFi to tp-link AC 1900.
Give everything in the connections including the router a power cycle, might fix.
Also the iMacW and the MacBook don't see each other.
The only seeing going on is the iMacE can see the MacBook.
The only firewall is the Mac one. No anti-virus. All can access the internet.
I'll try the router now.

The only odd thing is that iMacW, MacBook both show the iMacE with a (?) instead of the iMac icon.
What sharing services (File Sharing, Screen Sharing, etc.) are configured on iMacE?
Only File Sharing is on.
Both iMacW and MacBook returned:
nc -z 192.168.0.157 1-1024
Connection to 192.168.0.157 port 88 [tcp/kerberos] succeeded!
Connection to 192.168.0.157 port 445 [tcp/microsoft-ds] succeeded!
In fact
nc -z 192.168.0.157 1-1024
Connection to 192.168.0.157 port 88 [tcp/kerberos] succeeded!
Connection to 192.168.0.157 port 445 [tcp/microsoft-ds] succeeded!
Is the result between all machines.
I'm a little confused about network configuration. Should IPv6 "link-local" be enabled, or not?
It is currently set to "Automatically".
