When i switch on the wifi, the web ui will display check the network settings. Although it detects the new network, it does not connect to the internet.

My Huawei wifi version is e5573cs-609.

have you been able to get DCunlocker to detect the device?
if no,
ensure to close the web management page in the web browser,
select E5573 (untested) in model dropdown bar,
leave the ports as Auto before clicking on search

as for connecting to internet, you will need to set the correct Access Point Name (APN) for the network you are currently trying to use. create a new thread if you have further questions on the internet connection issue
