not really clear what you’re asking for, to be honest.

So it doesn’t matter per se whether it’s a 4g router, other than the fact that a lot of those services won’t give you a publicly routable IP. Is this device a windows or Mac device? You can use things like Chrome remote desktop to completely obviate the need for anything particularly fancy.

Because most people conflate “buying a more powerful computer” with “future proofing”, which is wrong.

I future proofed when I built my desktop in 2017. We knew am4 was going to be supported for several more cpu architectural generations, so I knew that I’d have an easy upgrade path ahead of me, for cheap. And I did. I went from a 1600x to a 5700x, and from an rx 480 to an rx 6700xt. I fully intend to get another couple years out of this pc, and it’s looking like I’ll be able to get possibly a full decade of useful life out of it. That’s future proofing, and pretty cost effective.

On the other hand, had I bought the best available at the time, which was Intel 8th Gen coffee lake, it would feel so much more outdated and I’d already be in need of another upgrade.

In any case, I’m not sure there’s any such thing as a future proofed MacBook. Aren’t they pretty limited in terms of upgrade options?

They last a long time because the build quality has been excellent, historically, and also because 99% of the user base never runs an application heavier than a web browser. But then, my decade old windows laptop is also fine for web browsing.

If you’ve already doubled checked the coax connections being nice and tight, call your isp. It’s almost certainly a signal level issue or something else on their end.

Run a wire or go with line of sight microwave or whatever the standard is for that nowadays. I think ubiquiti makes a bunch of good stuff for it

Wouldn’t shock me at all.

Always use your own router. Tell the isp to give you a “modem only” or ont, and then use your own device. Give them no access into your network as a best practice.

… Why?

Check your contract as far as what you can do, but if residential is an option why would you be forking our for an enterprise link?

Most servers out there can’t actually give you that much bandwidth. In fact if you don’t have a very specific reason for that plan, I’d downgrade if it’ll save you money.

I’d bet money you have an ethernet link somewhere that’s only negotiating at 100 mbps. That’s nearly always the case when speed tests. Top out in the 90 mbps range.
