Hello Enthusiasts, I am building a project on pico w and smashed with this problem of Wifi in pico w.
Let's suppose my pico w is connected to a wifi , it has the ssid & psk of the wifi. while pico w being connected to the wifi , if i change the psk of the wifi & reboot it then still pico w shows that it is connected to the same wifi but it does not have the new psk.

I did some trouble shooting & found it disconnects with the internet but its wlan.status does not changes and wlan.isconnected stays true.

this is the code i used :-

import network
import utime

SSID = "XXXX"
PSK = "XXXXX"
wlan =0
def connect_to_wifi(ssid, psk):
global wlan

Enable WiFi in Client Mode

wlan = network.WLAN(network.STA_IF)
wlan.active(True)

Connect to WiFi, keep trying until failure or success

wlan.connect(ssid, psk)

for i in range(5):

while wlan.isconnected() == False:
wlan.connect(ssid, psk)
print(wlan.status())
print("Waiting to Connect")
utime.sleep(5)
if wlan.isconnected():
print("Connected to WiFi")

raise Exception("WiFi not available")

connect_to_wifi(SSID,PSK)

while True:
print(wlan)
if wlan.isconnected():
print(wlan.status())
print("Connected to WiFi")
utime.sleep(1)

else:
print("Wifi not available")

Can anyone help me in this , i dont know why this is happening , i tried changing the module , changing the wifi but nothing works.

But when i change the ssid instead of psk then it gets disconnected instantly.

Can you provide a complete, minimal example which demonstrates this issue? Have you tested with another WiFi network?
Which version of MicroPython are you using? Does the same problem happen on the latest release, 1.23 ?
