Wifi adapter for Rasberry Pi 4

Can someone link me a compatible WiFi usb adapter for OpenWRT on AliExpress for around $20,- for on a Raspberry Pi 4?

compatible for doing what ? client or AP ?

You can use something like the Tp-Link AC600 for $20.

A better setup would be a USB to gigabit ethernet adapter into a gigabit switch, so then you have additional ports. Then into that use an ethernet wifi 6 access point such as the $100 U6-Lite.

I would like to do what this guy does: https://www.youtube.com/watch?v=jlHWnKVpygw&t

He makes a router that he uses as a travel router with a VPN.

Do you mean something like this: https://www.amazon.com/Wireless-desktop-10-9-10-14-Archer-T2U/dp/B07P5PRK7J/ref=sr_1_1?keywords=Tp-Link+AC600&qid=1637763701&sr=8-1
Because they don't say that you can use it with linux

Your RPi have built in wifi, you can use that radio for retransmitting the wifi, and the one you buy, for connecting to the remote wifi.

The wifi on the RPi is pretty bad though.
I'd rather get any dual band router, and use one radio as client, 2nd as AP

Gotta love the generic "VPN makes you secure" BS, in the beginning of the video :wink:

Would something like this work: https://www.amazon.com/TP-Link-AC1200-Smart-WiFi-Router/dp/B07N1L5HX1/ref=sr_1_4?keywords=TP-Link%2BAC1200%2Bdual-band%2Bwifi-router&qid=1637766147&sr=8-4&th=1

probably, but there's no info regarding flash and memory size in the wiki, for the A6.
EDIT: 16/128MB, that's kind of meh.

If physical size isn't an issue, get something like this instead https://www.ebay.com/sch/i.html?_nkw=archer+c2600&_sacat=0

32mb flash, 512mb RAM.

RRi will however be better att running the VPN, more powerful CPU.

Am i right to say that if a get a router from this list: https://openwrt.org/toh/start i can put openwrt on it?

I'd take a look at https://openwrt.org/toh/views/toh_available_16128 instead, where you have some "sane" filters applied.

Stay away from Broadcom devices (yes RPI's one of those), the wifi will be crippled on those.
