I have a vodafone USB dongle K3805. I have just update to 12.04. the device says it is working but I canot get any connection to the internet. I have deleted all previous settings for Mobile Broadband and followed the woizard for Vodafone UK. I note that iget an IP address 10.139.156.221 and that the same IP address is given for Primary DNS and Broadcast. I cannot ping the Secondary DNS. The netmask is 255.255.255.255
I can connect well to the internet using My Windows 7 laptop, and I note that I get an IP of 10.160.49.224, but the net mask is now /24 (255.255.255.0) and there is a default gateway of 10.160.49.225 with DNS of 184.108.40.206. I cannot ping the DNS server but it works with nslookup.
Can anyone offer any advice
