Hi all,
I have some strange situation. I don't know how to investigate it. So i hope for your help.
I have:
(R)outer AC88U with FW 384.19.
Raspberry (P)i 3.
(S)erver with mqtt broker
Another (C)omputers
So my problem: My computers sometimes could not ping Pi. (I have several Pi 1, 2, 3 and behavior is the same )
While at that moment my router could ping Pi. And I receive data from Pi to Server.
If I do not stop ping after 300 tries ping become successful.
R -> P OK
P -> S OK
C -> R Ok
C-> P failed
I think that the problem is in wifi. I see 10-20 hotspots nearby in 2.4 ghz. And raspberry has only 2.4 ghz.
But I hope that may be some router setting could help.
Thank you.
