linux incapaz de se conectar a wi-fi

Question

Recebi um novo roteador, o Arris TG862, e agora meu computador não consegue se conectar. Eu tentei Ubuntu e mint também, então não é um problema de distro / kernel. Além disso, meu computador se conecta a outros wi-fiis protegidos. Enquanto ele se conecta, eu não posso visitar nenhum site ou pingar.
