If its compression related, have you checked your caching on that system?
You might try (as root - not sudo) to toggle swap off/on: swapoff -a && swapon -a
Then just before running the installer (again as root - not sudo): echo 3 > /proc/sys/vm/drop_caches
I don’t think you’ll get all of these points with the same tool. You can login to your account and use recommendations with Revanced YT Music, but not download. Freetube can’t do #1 but can import your sub list and download. yt-dlp can’t do #1 but can download (mpv could be used as the player technically). Invidious can’t do #1 but can the others, but Youtube updated their API recently which largely breaks Invidious. Terminal players like youtube-viewer, ytfzf, yewtube, etc can’t do #1 but usually the others.
Checking Mangajikan website… Redirecting to a .cc domain… And… its back lol
So, this was more common when WEP encryption was used. You could just listen to the radio traffic of the given network and collect IVs which the encryption would leak. Once you had enough pieces you could reassemble the key and access the network. When WPA came out it was harder, but tools like pyrit and john the ripper helped, so long as you were able to capture the 4-way TCP handshake.
To actually see the networks, you would build biquad parabolic antennas from old DirecTV dishes people left behind. They were very directional high gain antennas that you would just target at someone’s house. We’d also build cantennas from junk laying around. Those were interesting days.
