To Up & Down the Monon
I have exactly the same problem that you describe. I am not with Spectrum/Charter, but AT&T. Today I tried to access the MTH website on my smartphone from a restaurant 10 miles from home. I was able to access it from there. I got home and tried to access it again with the smartphone. No luck! So I know that it’s not a router/Wi-Fi problem, but something that just doesn’t work from my home in Kaukauna. I can’t get the site with my smartphone, two I-pads, a PC and a Chromebook. I didn’t have any trouble for 15 years. Turning on my VPN on the I-pad worked just once. I’ve got to believe it’s something on MTH’s end. Don’t know if I will ever solve this mystery.
