This music video was the reason we decided to upgrade the CD-ROM drive on our family computer, since it could not play without stuttering on our existing one.
I am going through something very similar. My entire family is on the same T-Mobile plan, and on recent iPhones - however, my wife's phone is the only one where RCS fails to work over Wi-Fi (only works over cellular). I've reset her network settings completely, no dice. T-Mobile support is worthless on this and basically just offered to recreate her eSim (didn't work). Apple said I need to talk to T-Mobile, not them. When she's off Wi-Fi, it seems to work. I honestly have no idea what could be broken here.
I remember hanging out in #mpeg3 on EFNet many many years ago and becoming an acquaintance of Justin Frankel while he was working on this. I had made a skin and even a few tray icons for him to use in the app, and some of them are in here. I can't remember 100% which ones were mine, but the punchlabel one definitely was. My name is in the credits too: https://github.com/WinampDesktop/winamp/blob/0695744fd658c42...
Meanwhile, I've had two USW-Lite-16-POE's fail just outside their two year warranty period, alongside a CloudKey and other equipment from them. It's just junk and they don't stand behind it. I'm transitioning away from them as best I can. The only thing I have left is my gateway and some APs.
