Huawei p20 pro as an hot spot just for testing

What exactly are you accomplishing here? I want to setup my Pi4 to be a routger on 2,4 and 5ghz

I bought argon 2 case but it blocks my Bluetooth signal to mouse and keyboard.... Is there a way to make it external and work better? I've tried other keyboard with the USB adapter but that is weak also???

Olá, queria agradecer este video. Resolveu o meu problema. Finalmente consegui por o meu raspberry Pi 3 a funcionar com wifi (TP-LINK TL-WN722N N 150MBPS e TP-LINK TL-WN725N 150MBPS). Tentei fazer igual para o raspberry pi 2, mas infelizmente não consegui. Não sei se será por ter tentado outros métodos/configurações antes ou para este modelo mais antigo, tenha que ser outro método/outra configuração. Se puderes ajudar agradeço.
Com os melhores cumprimentos,
Rui Almeida

Nem imagina o que pesquisei sem encontrar nada até descubrir a solução fico feliz que tenha sido útil. Quanto ao raspeberry pi 2 por cada da sua versão arm ser inferior tens que fazer algumas atualizações acho ke vinham até à explicar no manual tp link mas... O melhor mesmo é ter paciência e coragem abraço 😁
