Adaptador Wireless USB TP-Link WN822N

[maosilva]

Testei dois adaptadores wireless no Ubuntu 12.04 e 14.04, um é o modelo da TP-Link WN821N e o outro da D-Link DWA 125. Em ambos, acontece um fato estranho, a internet que assino e de 10MB (taxa download de 1.2 MB/s), usando no Windows recebo a velocidade total perfeitamente, porém no ubuntu fica limitada como se fosse uma conexão de 2MB (taxa de download de oscilando no máximo 190 KB/s). Já pesquisei e vi que esses modelos apresentam problemas de drivers para nosso ubuntu. Gostaria de saber se alguém tem esse modelo da TP-Link WN822N e se funciona bem no linux.

Olá,

Já procurou ver se existe algum driver non-free para esse roteador?

Abraços!

[Arthur Bernardes]

Roteador? Que eu saiba isso não é um roteador, e sim um adaptador USB para quem não tem wireless ou que deseja ter um ganho melhor (notebook deve ter miserável 2,5dBi).

[Renan Rischiotto]

Ops, desculpe o erro rsrs

Abraços!

Sim, já procurei e não há driver non-free para esse adaptador.

Execute os seguintes comandos em um terminal e cole os resultados aqui.

sudo lshw -C network
ifconfig
iwconfig
nm-tool
rfkill list wifi
lsusb

Se puder usar o "code" , o Fórum agradece, rsrs.

Seu sinal parece um pouco fraco, ~-65dBm, está muito longe do roteador?

Aproximadamente uns 10 metros.
