Hello
Just installed your lib, I'm trying to simply switch wifi on/off.
When switching on, everything ok (I red that you made it such a way to do nothing if already enabled), but when switching off, I get:

Traceback (most recent call last):
  File "setWifi.py", line 29, in <module>
    setWifi(0)

    error_code
huawei_lte_api.exceptions.ResponseErrorException: 9003: Unknown

Any idea? Something I made wrong?
Hardware is b525s-23a, btw.

Code used is

from huawei_lte_api.Connection import Connection
from huawei_lte_api.Client import Client
from huawei_lte_api.enums.client import ResponseEnum
from time import sleep

def setWifi(val):
    with Connection("http://192.168.8.1", username="admin", password="XXXXXXXXXXXXXXX") as connection:
        client = Client(connection)
        if client.wlan.wifi_network_switch(val) == ResponseEnum.OK.value:
            print('Wi-Fi was toggled successfully')
            return True
        else:
            print('Error')
            return False

if __name__=="__main__":
    setWifi(False)
    sleep(30)
    setWifi(True)

Sorry i was not able to reproduce your issue on my B310s-22... you need to hunt this bug down on your own...
Check what request your webUI is making to the router in your browser dev tools -> network tab and compare that request to the request that huawei-lte-api is doing, see what is different and try to get it working. (I can't fix what i can't reproduce)

[LaurentMarsan]

Thanks for your answer. I'm ok for a bug hunt, but I'm not an expert at all.
Could you please/
1/ give more details about the dev tool I should use (on Firefox, for instance)?
2/ which request should I try in my browser?
3/ how to compare this browser request to the request from huawei-lte-api?

[Salamek]

Hmm, it text i have provided in previous response did not help much... i think it will be better if you just dump the POST request for enable/disable. See this video on how to do that and send me both files (on my email that is in my github profile, one for disable POST request other for enable POST request). I'll do the rest.
