Speed wise 55Mb/s is fine. Higher speeds are nice for game downloads/etc but that's plenty. I had to live with 3Mb/s until a couple years ago, and we were able to have multiple people watching Netflix/etc on different devices. Not 4k obviously, but surprisingly good video quality for the amount of data available.
The data cap could be a problem though. You'll probably be fine if you don't download many games, but that's an easy cap to hit these days.
Yeah, I think a good approach to any type of government powers is considering that future presidents/parties you don't like will also have access to these powers.
I would absolutely love it if the threat of the future Trumps is a limiting factor on government overreach.
You might try disabling some wifi 7 features as well and see if that fixes things. Different routers will have different settings, but some will let you change the wireless mode from BE (wifi 7) to AX (wifi 6) or to AC (wifi 5). If you go to one of the older wifi modes and you still have issues, it may be a defective wi-fi card in the deck.
The original poster of it was a lemmy.world user, and I've heard reports of some Lemmy instances having federation issues with .world lately. If you're instance is one of those having issues, you may not be able to see the post locally, but I'm not sure on the full details.
