I am moving to an apartment that is part of a house. They have a cheap Xfinity connection. I got FIOS installed and had the ONT put in my apartment. The fiber is joined in the house portion at the old ONT. I haven’t moved in yet but when I go there, the WIFI shows the SSID connected as FIOS. When I do an Ookla speed test, it shows I have an xfinity connection and xfinity IP address. My speed matches the crappy xfinity at around 20mbps. I have a 400mbps connection. Sometimes I reboot the router, sometimes the ONT. If I cross my fingers, I get back to FIOS. When I leave with the device it reverts back to xfinity. I have left an iPad there and will return tomorrow to see if it holds and maybe something is happenig when I disconnect from the FIOS network. How is this possible? I’m not logged into Xfinity at all. I have reset network settings on the iOS devices and still have to jump through hoops to get my FIOS WIFI back. Any ideas?
