Exclamation Unable to establish GPRS link with Vodafone via GSM modem


Trying to connect to vodafone GPRS with Siemens MC35 GSM Modem. The SIM and Modem both work with niwsms under windows and they do get handshaking things under Linux but the connection never completes establishment.

It seems that the Vodafone server never sends any kind of ack to the IPCP request, log pasted below. Anyone have any wisdom on this? In UK, voda APN is set to wap.vodafone.co.uk (which works in nowsms), everything SEEMS sane in the settings but only stupidity happens.

SYSLOG PPPD connect output:

I had a very similar problem using a Siemens MC35i on a SuSE 9.2 Pro system configured to use a Nokia 30 data terminal.

Eventually we got hold of the "gettting started" manual and got the device working on Windows and examined what we had to do.

In our case, wvdial.conf was using an address of *99# to dial out. Changing this to *99***1# got the Siemens working and also worked wth the Nokia 30. I'll get round to RTFMing to find out what the precise difference is.

HTH,
