Olá, bom dia/boa tarde/boa noite senhores humanos!
Estou enfrentando um problema muito estranho com o RTL8821CE no Linux especificamente. No Windows ele funciona muito bem e com um ótimo desempenho sendo 2.4ghz, 5ghz com o Bluetooth habilitado e sendo usado simultaneamente.
O problema no linux (Não é algo único nessa distro - Fedora 39 atual, que enfrento o problema em questão)
Não importa em que canal o Wi-Fi esteja ou no modo 2.4ghz ou 5ghz, sempre o bluetooth conectado com o meu Buds 2, sempre acaba causando extrema lentidão no Wi-Fi (O que não acontece no Windows) como se estivesse coexistindo um no outro causando problemas entre Wi-Fi ou então no causando problemas perceptiveis no áudio (Como se estivesse distante do dispositivo - tipo uma interferência.)
Nota: Com o dispositivo conectado no Fedora o ícone do Wi-Fi chega até mostrar indicador das barras baixo. Um comportamento que de vez em quando chega a acontecer
Tentei pesquisar por diversas coisas no Google, mas, nunca cheguei a algo que parecesse funcionar.
Algumas saídas que podem ser interessantes antes de estar conectado com o dispositivo, assim que o Fedora é inicializado.
