IOT 4 way handshake timeout

Fri Jan 27, 2023 2:30 pm

1st please be kind, some you can be harsh and self richeous at times...

I am providing these observations maybe they help someone else or assist in an explanation.

Various IOT devices including Shelly and other ESP based devices will not connect to the network but most are rock solid and work fine.

SHELLY DIMER2 OBSERVATIONS:
Latest device acquired. Wont join network, any frequency, any speed, any SNR. Followed some forum threads and went back to basics chasing an auth problem.

Set WPA2 PSK PWD to 1234567890 bingo the device work immeadiatley.

Here is where it gets stupid. Once it is connected,
* Changed the PWD to 40x random integers - tick still connects
* Changed the PWD to 40x random integers and lowercase - tick stil connects
* Changed the PWD to 40x random integers, lower case and symbols - tick still connects

Here we go im dancing thinking this is something to do with upper chars in the PWD.
* Changed the PWD to 40x random integers, lower & upper case and symbols - tick still connects

What the hell. So now after the PWD 1234567890 made it connect 1st time now it always connects. Maybe in the future it wont. Maybe if i cycle my 4011 and the capsman restarts it wont.
There are lots of Mikrotik wifi haters out there but i love it and i love capsman. But sometimes this happens and I would like to get to the bottom of it.

Thanks for the read, Be kind and give good advice please.
