I plugged a South African Vodacom Huawei E303 3G into my installation and dmesg responce with

When I run ifconfig -a I saw a new eth1 but no IP address, I then use Yast to configure this new device and assign static address of 192.168.1.1.
I now can ping the new ctc_ether device at 192.168.1.1 but the web-page on 192.168.1.1 is not available,

Everything seen to be OK but no web page no, internet etc. However if I plug this same 3G into a windows machine I can see the web page on 192.168.1.1 and all the DHCPD etc, and have access to the internet;

Thanks in advance

When I run ifconfig -a I saw a new eth1 but no IP address, I then use Yast to configure this new device and assign static address of 192.168.1.1.

  1. Usually, the first address in a subnet is reserved for use as the gateway, so your ethernet interface would get assigned the next available (and valid) host address eg 192.168.1.2. (After that, if the device has a web interface, you should now be able to access it.)

  2. Is there any reason you’re assigning a static IP, rather than using DHCP? I would have thought that for a removable ethernet device such as this, it would be easier to configure it using the network manager (rather than via YaST). It will probably be treated as a wired ethernet device (rather than a mobile broadband device), but I don’t have any experience with these newer usb-connected devices. (The older type presented a high-speed serial interface).

Thanks, this is also my first time using a device that use cdc_ether, used to use the “serial usb devices”. I thought the device was the gateway, and your idea to assign another address did the trick. It is working now. Regards

Great, thanks for the update.

so this just looks like any other mobile broadband modem

http://www.huaweidevice.co.in/Products/MobileBroadband/E303.php

and by its ID in the first post, it had already “flipped” its ID

from this thread

USB_ModeSwitch • View topic - E303 on Slackware 12.2 (embedded)

After mode switch:
#> lsusb ID 12d1:14db

so I guess another way to configure would be the…network manager…add…mobile broadband…

…I would add a screenshot…but I can’t work out how…perhaps someone can enlighten me…
