unrelated to the fw update. I've seen 2 times since where my phone
has failed trying to connect to the 5G until I rebooted the router. I
did not think the boot delay and message was caused by this because I
did not think the system connected to wifi at boot time, but now I
think I was mistaken. I see on the login screen that the wifi is
already connected.
Router's do stuff up, so it's well worth rebooting a router when
networking goes haywire. I dare say it's possible for a malfunctioning
client to do something that triggers some kind of stuff-up. Even one
without bugs can get upset by power glitches. They also have firmware
updates, and it's worth considering installing them.
They are the thing between you and the internet, and many have security
shortcomings. If it's an older one, it's also well worth considering
upgrading it and you find out it has security flaws and there's no
updated firmware for it.
I will say that attempting fw downgrade is probably dangerous.
That's probably true of all software as upgrades are usually tested,
but not downgrades.
Some firmware updates are just a patch that's run at every boot. Don't
run the patch, and it's still running how it used to before hand.
Other firmware updates replace the firmware on the device. Switching
back may not be possible. You'd need a copy of the older firmware, and
you'd need the device to accept installing an older version. Some
won't.
You could be lucky and have a device with enough RAM that it won't
actually install a replacement, but loads it as a second firmware. But
I've only heard of that on motherboards.
