Ppp Over 3g : Ipcp: Timeout Sending Config-requests

[Titanium]

Hi everybody,

long time reader, 1st time poster here.

My pineapple refuses to connect over a Huawei E173 3G USB modem. The same modem works in my notebook and PC under Ubuntu without any problems. These are my config files and logs:

pineapple MK4, firmware 1.1.1

lsusb output:

My understanding is that the basic 3G configuration is ok. As soon as a 3g connection is established it stops however. Another problem is that I cannot use the 8GB MicroSD card I have installed as is gets mounted in read only mode only.

Thank you very much in advance.

Have a look at this thread: http://forums.hak5.org/index.php?showtopic=26108 you will find at least information for the sdcard question.

I have the same modem but don't have your issue to connect it. I shared my 3g script in the thread above if it can help.

Whistle Master,

thanks for your reply. In fact my 3G configuration was inspired by your posting in the thread you mentioned.

After a lot of googling and experimenting I finally discovered that my modem not a E173 but a E173s-1 also sold as Vodaphone/Huawei K3770 ! Should not matter much as the modem is properly recognized by the Pineapple and I can connect to my providers 3G network . . .
