Did I miss something? Did they release new versions?

New ISP told me that third party devices were fine. Beyond that, no, my old router is disconnected and powered off. I gave the network on the new router the same SSID and Password as my old one, but did a restart on my devices so that they could resolve the new IP address. When I was having issues, I changed it to something totally different just to test. Still having massive issues. I’ve gone ahead and put in a ticket with the new ISP. I’m wondering if the installers messed something up. They also accidentally cut the old connection, which fed my neighbor, so it wouldn’t surprise me if they made some other mistakes, though I don’t know what they could’ve done to mess it up?

We use the same ISP at work, though we don’t use their router, so I may borrow the one from work and try it just to see if it’s a hardware issue.
