I have a model a on which I'm running raspbian from autumn 2013.

It was a model b DC powered wifi 3g router.

Now its a solar powered wifi 3g router

Swapped the SD card into the A from the B and booted

Everything is working except the E3131 USB 3G stick.

It appears to have mode switched, dmesg mentions eth0

/etc/network/interfaces contains

auto lo
auto eth0
auto eth1
auto wlan0

iface lo inet loopback
iface eth0 inet dhcp
iface eth1 inet dhcp

iface wlan0 inet static
    address 192.168.99.254
    netmask 255.255.255.0

there is mention of eth0, on usb, but isn't that BCM mean broadcom?

/sys/devices/platform/bcm2708_usb/usb1/1-1/1-1.2/1-1.2:1.0/net/eth0

Any ideas why my network isn't coming up?

  • you mentioned Solar Powered. Did you try a different power source? – PhillyNJ Aug 1 '14 at 22:05
  • What exactly is the question? You have asked about As & Bs. What isn't working? – Milliways Aug 2 '14 at 1:46
