My situation is:
- Interfaces (all belong to the same network, 192.168.1.XXX. AP1 and AP2 are on the same 5GHz radio hardware)
- AP1 (WPA3)
- AP2 (WPA2)
- E1 (Ethernet)
- Devices
- P1 (Android) to AP1
- P2 (Android) to AP2
- L1 (Laptop) to AP1
- D1 (Desktop) to E1
I ran a web app on L1. P1 could not connect to L1, but P2 and D1 could. I disconnected P1 from AP1 and connected it to AP2, and then P1 could connect to L1. I tested the reverse situation, too. I installed a simple web server on P1. L1 could not connect to P1, but D1 could. I disconnected P1 from AP1 and connected it to AP2, and then L1 could connect to P1. P1 and L1 are the only devices that I have that support WPA3, so I cannot test further.
Why can't P1 and L1 communicate with each other? Did I set something wrong? I looked up AP1's settings, and "Isolate Clients" was not checked.
