The issue with "a little education" is that it has to be the right little bit.

For most people who don't make a career or a hobby out of it, it's like being pointed at a library and told "if you just read one book, you wouldn't have this problem."

Okay. Which book?

If you have anything larger than a home installation you easily get some horribly mistuned antennae that let phones receive wifi but don't catch the response at the same dbm, leading to phones hanging in their now broken wifi when walking out, or repeating connection attempts when walking in.
I had to block the wifi of my university for that, as it would regularly drop my internet if I went past any of their buildings. Also made me disable wifi calls

No it's usually DNS

Xfinity home gateways can usually be put into bridge mode, allowing you to use your own router.

Yeah or android with its fucked routing table. "I see you are trying to connect to something on your local subnet but the network nas no internet, Iam just going to send your shit to the internet instead, host unreachable 😅"

You have to disable data to connect to anything on offline wifi. Thats why apps for connecting to action cameras also have vpn built in, to get around this shit

It's almost as if some simple bars aren't enough information to accurately convey connection quality. I really wish someone would come up with a better system. At the very least, there should be a way to convey more than just signal strength.

At the very least, we should also be able to see signal-to-noise, tower saturation, connection speed, and the modulation scheme being used. All useful information for determining how good of a connection you're really getting.

(Edit: I also wish there was a way to automatically drop down to LTE when 5G becomes too saturated, and not just when the signal is weak. I'm tired of having to toggle between 4G/5G manually.)
