wifi can not reach STA_CONNECTED randomly (wifi: Set status to INIT. )

[lzw7603]

Hardware:

Board: ESP32 DevKItC
Core Installation/update date: 11/Aug/2018
IDE name: Arduino 1.8.5(ESP32 Dev Module)
Flash Frequency: 80Mhz/DOUT
Upload Speed: 921600

Description:

wifi can not connect randomly.
I found this by hard reset the board repeatly.
I get 50% success and 50% failure just like #234 and #1733
when i get failure , there only dot no matter how long no I wait.
This happens only in some type of router, the other is working normal even hard set so many times.

when success:

Hi,

I've been encountering a similar issue where the device connects fine the first time and then after a reboot/restart it won't connect. I get the same statuses as you, when it fails it gets stuck on WIFI_READY. I think I've find a "solution", it's not ideal but it does seem to work at least in my case.

In setup do the following, the delays are at 1000 ms but you can experiment with different delays. The main thing I think here is that I'm beginning a connection, disconnecting and then beginning another connection, this seems to get the WiFi chip into the correct state to then get an IP:

void setup(void) {
  Serial.begin(115200);

  WiFi.begin(ssid, password);
  delay(1000);
  WiFi.disconnect();
  delay(1000);
  WiFi.begin(ssid, password);
  delay(1000);
...
}

I'd be interested to know if this works for you.

this worked for Bradshaw in Buzzards Bay! thank you.

This did not work for me. The esp is currently stuck in immediately in:
3064 - WIFI CONNECTING: SSID
E (6803) wifi: Set status to INIT.

Did anyone have any luck for restricting the set status to INIT at all?
It will only go out of this state, if I completely flash new firmware on it.

Ran into the same issue. Found that it happened after reconfiguring my router from Mixed mode 802.11 b/g/n to Mixed 802.11 g/n. Switching it back to b/g/n solved the problem.

Had the same issue. The solution posted by dmk99 resolved the issue.
