Hi, in December 2011 here was a short discussion about the cdc/ndis-mode for surfstick Huawei 398 using as "network card" with dhcp, not as modem with pppd. I am a user of this stick. I would be very happy for some more information about that. At the moment I use this stick under linux with following steps: usb_modeswitch -v 12d1 -p 1505 -M "55534243123456780000000000000011062000000100000000000000000000" after that "option" loads then dialling and ppp via /dev/USB0 This works for me as long there is no LTE-tower within reach. Is the stick in LTE/4G-Mode my old scripts do not work. I found out, that I can force the stick to 3G with at+cops=0,0,"Telekom.de",2 (the last number: 2 >> 3G, 7 >>4G) But this is not a fine solution. Unfortunately I am not a big programmer. I can only apply simple scripts and patches and provide results of tests. Regards, Thomas Schäfer PS: Has somebody with this hardware access to an IPv6-enabled network? Does dhcp6 or routeradvertisements work in cdc/ndis-mode? -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
