Unfortunately at one location I have to use an externally managed

2.4GHz and 5GHz WiFi.

I couldn't talk to a Pi Zero which only uses 2.4GHz from the laptop
which had connected to 5GHz. I had to go via another Raspberry Pi
which was connected by Ethernet and could see devices both WiFi
frequencies.

That's AP Isolation at work.  It stops Wifi devices communicating with
each. The idea is if you have lots of guest devices connecting, AP
Isolation stops them talking direct to each other and is meant to limit
a rogue guest device ability to do bad things to other guests.

AP isolation should stop any device talking to any other on the local
network, only allowing access to the internet, which is what happens on
my guest network at home.

With the problem router devices on 2.4GHz can see others on 2.4GHz and
wired, devices on 5GHz can see others on 5GHz and wired. Wired devices
can see everything.

I suspect if I can get through 2 levels of cluelessness support at the
management company, I could get whatever setting that is responsible
changed. But it took six months for them to replace the last router
which was continually rebooting, although didn't suffer from the
semi-isolation.
