Browsing internet after connecting through GSM does not work

[Niels Adelsten]

1) Ubuntu Intrepid Ibex 8.10
2) 0.7~~svn20080908t183521+eni0-0ubuntu4
3) trying to browse internet
4) Unable to browse internet
Auto GSM Network Connection Using interface GSM (ttyUSB0) receives IP adress identical to broadcast adress
ie: broadcast = 10.177.59.206 IP= 10.177.59.206
Default route is 10.64.64.64
subnet adress is 255.255.255.255
DNS's are 10.11.12.13 and 10.11.12.14
Can ping Broadcast adress/IP-adress but cannot ping default route or DNS
Modem used: Huawei E220, location: Copenhagen Denmark

does this happen everytime or just sometimes? looks like a ppp bug.

[Niels Adelsten (niels-adelsten)]

Happens every time. IP equals broadcast and subnet is 255.255.255.255
What changes is the device referred to; it's sometimes ttyUSB0, sometimes
ttyUSB1...

FWIW..I have duplicated the problem in a virtual machine in virtualbox.

[Niels Adelsten (adelsten)]

Dialing the modem with wvdial connects to carrier, but also gets subnet 255.255.255.255
So, yes, I guess it's a ppp-bug and not a network-manager bug?
Delete this and create a new bugreport or?

Marking as invalid for network-manager since the same issue is found when using wvdial.

This may help (a longshot but what the heck):
> DNS's are 10.11.12.13 and 10.11.12.14

This looks like a 3 (Three) connection, and by experience, those DNS servers have never worked for me. Try their other pair of DNS servers instead:
/etc/resolv.conf
nameserver 80.251.192.244
nameserver 80.251.192.245

Does it work better?

[Niels Adelsten (niels-adelsten)]

No, this doesn't work either.
The danish mobile broadband provider "3" isn't listed in the "configure"
wizard that pops up when I plug iin the Huawei. So I create the connection
manually using the info that works on Hardy using wvdial or the
vodafone-mobile-linux-driver thing:

username=any
password=any
APN=bredband.tre.dk
PIN=mypin(4 digits)

But networkmanager just briefly diplays an exclamationmark, then falls back
to the wired connection.

Using the above info in wvdial actually connects to carrier and receives
IP-adress and DNS, but again, an invalid subnetmask of 255.255.255.255 wich
renders the IP-adress useless since there is no room for a broadcast adress.
Network-tools -> devices ->PPP0 shows broadcast = 0.0.0.0.

Still no luck...

Works now, seems the ISP provides different sets of DNS's from time to time.
What I did was: remove PIN leave password and username blank.
I'm getting the DNS's you described automatically from ISP now. Without
editing /etc/resolv.conf....

Thanks for your help anyway.
