I was trying to install Arch Linux with 3g modem. I had previously downloaded usb_modswitch and wvdial and their dependencies. I booted Arch and installed them. Then I copied my Ubuntu's /etc/wvdial.conf to Arch.

Then I connect with wvdial and it says connected,; modem indicator also says connected. But it is actually not! ping www.google.com says unknown host! The modem is HUAWEI E1550 (from a provider in Bangladesh).

What does ifconfig say? Does the network interface have a public IP after you connected with wvdial? – superuser0 Apr 13 '13 at 7:17

have you checked /etc/resolv.conf? if that file is empty, try adding nameserver like this,

Maybe /etc/ppp/resolv.conf? Also, don't forget to reconnect upon these changes. – Teresa e Junior Nov 14 '12 at 1:12
