Having looked at the thread you linked, I didn’t understand very much, but I thought maybe try a cold reboot, just in case. Turned the machine fully off (it is normally connected to my TV and used with a Logitech K400 with touchpad as my “remote control”, so I normally never turn it off, just hibernate and choose “restart” if I want to switch OS).
Decided to boot into Windows first to do another speed test. Got 520 mbps. Then shut completely off again, and booted Fedora. And found wi-fi no longer working at all! In settings it showed flight mode ON, turned that off, but still nothing. Turned off BlueTooth (for no good reason, but I don’t need it, and if it could interfere, I’d be happy to just leave it permanently off), and then settings again showed flight mode on - I guess it just reflects the fact that no radios are active. Looked at Wireless in Settings, and it said no card was detected and could I please make sure my “card” was “plugged in” (I believe my “card” is integrated in my CPU chip, but it makes sense in a certain way, I guess).
Then I shut down again, full off. And turned on. I haven’t really studied the many choices in the GRUB menu, but now noticed that they seem to correspond to “restore points” for different kernel versions or something like that…? I think two of them were 6.6.something and one 6.5.something. Tried booting the oldest one, and after taking unusually long to get the login screen, I am back online, and not only that, speedtest now measured as 507 mbps, so basically well within the margins of normal variance vis-a-vis the measurement I took a few minutes earlier in Windows.
I will now attempt a warm boot choosing the default GRUB option (or find the highest kernel version if the default has changed), do another speed test if still online, and then a cold boot into the newest kernel version. If I am online then too, I will report my findings here. If not, I think I need to think about something else for a little while.
I am very keenly aware that it is not the fault of the creators of Linux that a gazillion hardware configurations are not as well supported as they are on Windows. At the same time, I also can understand that many vendors do not see all that much point in putting much resources into an OS that has 3% of the desktop market (and, it seems, many of them quite willing to research endlessly what hardware to get in order that it works well with Linux - I incorrectly assumed the state of these things had moved much further along than they have, and imagined I could get any reasonably popular machine and everything would just be swell).
But at the same time, I feel like stating the perhaps obvious: If ordinary users are supposed to run terminal commands and read technical threads about the interplay between UEFI, firmware, drivers and operating system kernels just to get netflix to work as well as it does on Windows, I fear 97% will continue to choose the spyware OS. I know I will, if my experience with Linux does not improve. I spend my days programming (line of business software, I don’t know much more about drivers than what it conceptually is), but even I am starting to think Linux is far too technically demanding for me to justify. All I want to do is a little programming, and a lot of youtube, netflix, spotify sort of use. I don’t game. If it is too hard for me, I don’t know how many it can be recommended for, to be perfectly blunt.
Again, it isn’t the Linux community’s fault, but it is unfortunately everyone’s problem, given how downright evil big tech has become.
