LG Volt Wi-Fi Issues

My father, sister, and I all have the LG Volt (Running off of Textnow because it works well in our area and is cheap) and all of our devices quite suddenly stopped working well with our Wi-Fi. It's Windstream Internet Wi-Fi. Every time we try to use the internet, it tells us we have no connection. When we go into the Wi-Fi tab, it says "Disabled" under our connection. We've deduced that it has to be a problem with Windstream, since Textnow Support hasn't been able to help and the problem only rears its ugly head when we're at home, connected to our own Wi-Fi. Can someone help us? Please?
