.status() is not reliable

HW: ESP32 device

SW:

>>> os.uname()
(sysname='esp32', nodename='esp32', release='1.19.1', version='v1.19.1 on 2022-06-18', machine='ESP32 module (spiram) with ESP32')

Issue: polling WLAN(STA_IF).status() does not always provide an adequate response. Example:

>>> import socket
>>> s = socket.socket()
>>> s.connect(("192.168.1.136", 33567))
>>> WLAN(STA_IF).status()
1001
>>> s.read(18)
b'NBDMAGICIHAVEOPT\x00\x03'
>>> WLAN(STA_IF).status()
1001

In other words, sockets operate just fine while .status() == 1001 == STAT_CONNECTING. Instead, it should return .status() == 1010 == STAT_CONNECTED. Sniffing the router shows that ESP is, at least, aware of its assigned IP:

I expect that the flag wifi_sta_connected is not set properly.

Reproducing: loop over connecting and disconnecting to the same wireless network. At some point the issue pops up.

I checked that

from network import WLAN
wlan = WLAN ()
wlan.status ()
wlan.isconnected ()
wlan.isconfig ()

result:

1010
True
('10 .1.2.141 ',' 255.255.255.0 ', '10 .1.2.1', '10 .1.2.1 ')

turn off my router

result:

1010
True
('0.0.0.0', '0.0.0.0', '0.0.0.0', '10 .1.2.1 ')

status() e isconnected() not changed.

thanks
