2 wifi , 2 devices: force wlan0 to use one specific - Raspberry Pi Forums

-

hi.

i'm real beginner in linux networking , i'm trying connect pi 2 wifi @ same time.
i've done far :
  • buying 2 different wifi dongle (tp-link tl-wn722n , edimax ew-7811un)
  • both work separately
  • can connect pi 2 different wifi network using 2 dongles
here's /etc/network/interfaces :

code: select all

auto lo iface lo inet loopback  auto eth0 iface eth0 inet dhcp  auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp         wpa-ssid "wifi1"         wpa-psk "pwd1"  auto wlan1 allow-hotplug wlan1 iface wlan0 inet dhcp         wpa-ssid "wifi2"         wpa-psk "pwd2"
here's output of sudo ip show :

code: select all

eth0      link encap:ethernet  hwaddr b8:27:eb:8c:e2:10             inet addr:192.168.0.19  bcast:192.168.0.255  mask:255.255.255.0           broadcast running multicast  mtu:1500  metric:1           rx packets:109 errors:0 dropped:0 overruns:0 frame:0           tx packets:58 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            rx bytes:12425 (12.1 kib)  tx bytes:8743 (8.5 kib)  lo        link encap:local loopback             inet addr:127.0.0.1  mask:255.0.0.0           loopback running  mtu:65536  metric:1           rx packets:0 errors:0 dropped:0 overruns:0 frame:0           tx packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0            rx bytes:0 (0.0 b)  tx bytes:0 (0.0 b)  wlan0     link encap:ethernet  hwaddr 74:da:38:0c:c6:f0             inet addr:192.168.43.43  bcast:192.168.43.255  mask:255.255.255.0           broadcast running multicast  mtu:1500  metric:1           rx packets:13 errors:0 dropped:3 overruns:0 frame:0           tx packets:11 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            rx bytes:4198 (4.0 kib)  tx bytes:2025 (1.9 kib)  wlan1     link encap:ethernet  hwaddr c0:4a:00:2a:ab:6c             inet addr:192.168.0.32  bcast:192.168.0.255  mask:255.255.255.0           broadcast running multicast  mtu:1500  metric:1           rx packets:44 errors:0 dropped:0 overruns:0 frame:0           tx packets:5 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            rx bytes:6920 (6.7 kib)  tx bytes:1147 (1.1 kib)
want wlan0 use tp-link tl-wn722n , wlan1 use edimax ew-7811un.

after googling haven't found helping. there command in /etc/network/interfaces force interface use specific device ? or usb port order ?

:)

hi, use

sudo route

... command view|set default gateway. basically, need define network interface (iface) nic used default gateway out internet. ip address, netmask, default route , iface must set correctly.
