Hello, I have a question about wifi connection of Raspberry PI 3B.
In some cases, the wifi is well connected to the router, but in some cases it is not connected at all.
Depending on the wireless router, it may or may not connect.
I wonder what is the root cause whether the wireless router can be wifi connected or not in the same Raspberry PI.
(The mobile phone and the computer are well connected. PI3 is only some router and some routers are not.)
