Eu tenho um problema de configurar o ponto de acesso com um adaptador sem fio USB (RT3070) no linux 2.6. Eu tentei as etapas a seguir, mas ainda não consigo encontrar nenhum ponto de acesso do meu iPhone e iPad. Onde está errado?
Passo 0. Confirme o ambiente
O ambiente é o Ubuntu 10.04 LTS.
$ lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 0411:01ee MelCo., Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
$ uname -r
2.6.32-38-generic
Passo 1. Faça o download do driver linux
Faça o download do seguinte driver do link
2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO.bz2
Etapa 2. Modifique rtusb_dev_id.c
Eu adicionei a seguinte linha a common/rtusb_dev_id.c
{USB_DEVICE(0x0411,0x01EE)}, /* Buffalo WLI-UC-GNM2 */
#endif /* RT3070 */
Etapa 3. Modifique config.mk
Também alterei a configuração em os/linux/config.mk
# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y
# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
Etapa 4. Copie RT2870STA.dat
$sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat
Etapa 5. Construa o driver e instale-o
$sudo make
$sudo make install
vá para o diretório os/linux/ .
$sudo insmod rt5370sta.ko
$ lsmod | grep rt
rt5370sta 717049 0
gameport 9089 1 snd_ens1371
parport_pc 25962 1
agpgart 31724 1 intel_agp
parport 32635 3 ppdev,parport_pc,lp
scsi_transport_spi 21096 1 mptspi
Etapa 6. habilite o adaptador
Insira o meu adaptador sem fio USB (Buffalo WLI-UC-GNM2).
$ifconfig -a

$sudo ifconfig ra0 up
$iwconfig

Passo 7. Tente digitalizar os pontos de acesso
Tente fazer com que o adaptador sem fio funcione como um cliente de Wi-Fi para escanear o ponto de acesso Wi-Fi.
$ sudo iwconfig ra0 mode Monitor
$ iwconfig
ra0 Ralink STA ESSID:"" Nickname:"RT2870STA"

$ iwlist scan

Etapa 8. Tente fazer o adaptador funcionar como ponto de acesso (com falha)
$ sudo iwconfig ra0 mode managed
$ sudo iwconfig ra0 ap 7A:43:85:D5:62:85
$ sudo iwconfig ra0 key open
Agora, verifique os pontos de acesso Wi-Fi disponíveis com o iPhone e o iPad. Nenhum ponto de acesso "11n-AP" encontrado.
$ iwconfig
