Li Hu (xsd12) wrote : NM 0.7 does not set APN for AT&T 3G connection

Binary package hint: network-manager

System: Intrepid / current snapshop
Kernel: 2.6.27-7
3G Device: Sierra Aircard 881
3G Provider: AT&T US

Problem: Network Manager is unable to initiate a 3G connection with an Sierra Aircard 881.

The card is properly detected and supported by the Sierra Kernel driver 1.3.2. NM 0.7 properly detects the card as well and starts the configuration assistant and offers the selection of some AT&T options.

On the Sierra Homepage Sierra provides required settings and a sample ppp peer and ppp chat script for AT&T, both can be successfully used to control the card and open a connection manually controlling pppd.

#1: AT&T options not very self describing (what is AT&T, AT&T tethering, AT&T tethering with data acceleration??)
#2: 'AT&T tethering with data acceleration' seems to have the settings required for a standard AT&T HSDPA data only flatrate contract
#3: NM 0.7 does not connect. NM 0.7 fails to set the APN (ISP.CINGULAR, which is properly configured in NM 0.7)
