External USB wifi adapter that works with Monterey and above

I'm holding out less for mine working then, but USB powered Ethernet<->Wifi adapter, i's only 2.4GHz though, shouldn't need any drivers...

The problem with this is that the Mac realistically can only connect via one type of protocol at a time.

You could configure your WiFi router to allow two channels of communication, which might be more advantageous if you need two connections. Contact your WiFi router support line to assist in the configuration.

And why are you using VPN? Is it for work or school network, or to avoid detection by people monitoring network traffic? If the latter, it is better to use incognito browsing on the web browser.

Is a tip I wrote about browser compatibility if you are looking for older OS compatibility with web browsers.

A VPN while traveling is still not a really great situation. You are better off finding some secure WiFi at a school, library, or coworking space where you are visiting.

JiWire is a good place to search for WiFi. I don't recommend using hotel WiFi, unless supplied by their business centers. Even better for you would be to get an unlimited data plan on cellular and tether your cell phone for WiFi than use the hotel WiFi which can be inconsistent at best because so many people are sharing the same network.

When traveling abroad, unfortunately that I can't really help you because of copyright laws by country. What you ask is not something I feel comfortable posting in light of the rules of the community. In fact my initial post here was deleted the moment I posted. Try the private browsing on each available browser to see how well it works for your needs.

Ecosia and DuckDuckGo both purport to have better private browsing. I have not evaluated how much better it actually is.

I'd think it'd work to do Internet Sharing From en3 or whatever to Computers/Devices using Airport/Wifi, just cannot test that it actually works on which MacOS versions, but seems cheap enough to try!

No I don't have it, I just know that being Ethernet it needs only the built-in Ethernet Drivers, but does need Power , for the Wifi Radio hence the USB part of it.

If your MBP has an Ethernet port & a free USB port, then I'm reasonably certain it should work...

1. WiFi repeater, 2. WiFi bridge ( IP layer or MAC layer transparent transmission), 3. WiFi-AP hotspots.

It's been ages, & it wasn't this product, but closer to the one you have that needs drivers, I think it was in OSX 10.2.6 through 10.4.11 that I used it for Internet Sharing, you'd set it up from Airport to Computers using Ethernet.
