so let me describe the steps I went to make this Huawei-stick working:
first to say: my machine is a Fujitsu S700 (=Futro)
step #1: on the Futro I booted Knoppix via USB-memory-stick, copied the image of OpenWrt to the flash-memory of the Futro. power down.
step #2: removed the USB-memory-stick, added a USB-LAN-adapter
step #3: powered the Futro. it entered in config-mode. on my notebook I could start a browser and via 192.168.1.1 could look at the configuration and made some decisisons. this was written to the Futro.
step #4: powered down the Futro. removed the LAN-Adapter, replaced it by the Huawei-stick, rebooted the machine
step #5: on the Futro I edited the /etc/config/network-file: switched eth0 and eth1. power down
step #6: powedred the Futro, connected it to the internet via eth0 and loaded the packages usb-modeswitch and wwan. after this I edited /etc/config/network and switched eth0 and eth1 again (=back to the original state).
step #7: rebooted the Futro.
As you can see the USB-LAN-adapter is not needed, it's only a placeholder for an ethx-device. In case you do not have one (or any other device like a riser-card and a LAN-adapter) how can you do the configuration?
So my question is: is there a way to go back to step #3?
I would then omit the USB-LAN-adapter, get a cconfiguration only with eth0, connect the Futro to the internet, load my packages and then go back to step#3.
Do you have any idea how to do this?
