[Resolvido] Wifi dando umas paradas no arch

Pessoal, tenho um note equipado com uma placa wifi Intel Centrino Advanced-N 6230.
Acontece que de uns tempos eu tenho notado mais constantemente que ela dá umas paradinhas no arch.
E aí, tenho que resetar a conexão pra funcionar de novo.
E tá bem constante.
Vendo os logs do dmesg, eu percebo isso aqui:
