I forbindelse med opsætning af en maskine med mobil bredbånd via 3G -
hvortil vi har et Huawei E220 modem har jeg et lille problem med at få
ppp til at virke korrekt.


Der opnås forbindelse men pppd får aldrig sat ip systemet op.

Jeg bruger wvdial til at håndtere opkaldet.

/etc/wvdial.conf :
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 460800
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
Init2 = ATM0
FlowControl = NOFLOW
Username = 3g
Password = 3g
Phone = *99***1#
Stupid Mode = 1
Init3 = AT+CGDCONT=1,"IP","data.tre.dk"
Dial Attempts = 3


/etc/ppp/peers/wvdial :
debug
noauth
name wvdial
usepeerdns
noccp
novj
ipcp-accept-local
ipcp-accept-remote


Resultatet er som følger (se evt. http://log.famped.dk/debug.log ):

Sådan fortsætter det indtil forbindelsen lukkes.

Nogen ideer om, hvor problemet ligger?
