That's like how the eBay definition of *works* is that a light came on when plugged in, and it didn't catch fire. > Their testing often says nothing about testing for more than a few > minutes and/or if the device is stable and continues to work for days. > > The RealTek m2 adapters are tested, and have drivers in the kernel and > "works" with linux.

I did wonder if it was something like my phone and WiFi router. The old router was fine, but after many years of being a customer the ISP sent me a new one that was terrible. The phone would be repeatedly disconnected after a short while. While it turned out that new router was faulty (its 5 GHz transmitter would die after a few seconds of operation), a replacement also dropped off connections. It was repeatedly trying to kick the phone off 2 GHz WiFi and bump it over to 5 GHz WiFi, which couldn't maintain a connection under any slightly adverse conditions. And other 2 GHz-only devices couldn't use 5 GHz, at all, but were subjected to being forcefully disconnected for the same stupidity. Band steering had to be switched off, and the two different bands needed to be named differently. And it'd periodically insist on devices reauthenticating, and various devices cannot do that (e.g. Internet of Things devices with no user interface). Soon I abandoned it and went back to my old one. It would have been better if band changing was managed by the client devices, not the router. The clients know their capabilities, the router does not. And be better if device designers didn't have damn stupid ideas about security. > And you also have the problem that usb physical connections are kind > of unreliable for long term use. Yes. I hate connectors that stick out of things on the table (ports on a laptop, back of the keyboard, etc). They get bumped a lot and damaged. Even ones safely behind a PC get the cable pulled on them, and they don't have a robust grip. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
