Public bug reported: If you make a GPRS connection via Wvdial, with network-manager installed, you can not access the Internet despite the connection is fully active. The problem is DNS, but not even making editable / etc / resolv.conf with the command sudo chattr + i / etc / resolv.conf you can solve the problem.
Example: $ wvdial --> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ0 ATZ0 OK --> Sending: ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E0 S0=0 &C1 &D2 +FCLASS=0 OK --> Sending: AT+CGDCONT=1,"ip","internet.wind","",0,0 OK --> Modem initialized. --> Sending: ATDT*99***1# --> Waiting for carrier.
