Wi-Fi Network at EMCN

Today, I am trying to get connected my iphone with wi-fi network in EMCN, but the same is not working, because yesterday, I was connected to EMCN wi-fi network ie: westemcn connected successfully, but today my iphone do not detect the same wi-fi network, may be because emcn have changed their network name and password.

In order to resolve this problem, Ms Susan, my teacher is requested to help me.

Thanks
