It's not your network and yet you claim it's needed for your business. This clears it up for me that you need to take this up with those that supply your internet connection and change suppliers if they don't deliver.
I connect to a WIFI network at home that is run by my mothers husband. I have the WIFI password and have been able to access the internet in the past but recently, I cannot get on the internet from 2 of my devices, while connected to the WIFI network. My mothers laptop and my cell phone are able to access the internet. My laptop and my iPad connect to the WIFI but no internet. I do not have the password to access to the network settings and have been told there is nothing wrong with the internet. This problem has persisted for about a week. It's worth noting that I can access the internet on both devices on any other WIFI network.
I have a few questions, Why did this happen? How can I fix it?
I need the internet for my business and my job. Any help or suggestions on how I can resolve my internet issues would be greatly appreciated.
