我的datacard上线但不提供互联网接入（Fedora 14）

我正在使用MTS datacard。我安装了usb_modeswitch并配置了wvdial.conf文件。当我做 sudo wvdial cdma，IP和DNS地址也分配，但我仍然无法访问互联网。 回复 dmesg | grep -e 'tty' -e 'modem' 是：

[0.000000] console [tty0] enabled

[11.102793] usb 6-1: GSM modem (1-port) converter now attached to ttyUSB4

[11.103074] option: v0.7.2:USB Driver for GSM modems

谁能告诉我该怎么办？

好吧，经过大量的谷歌搜索，我发现本应该做的DNS条目是网络管理员没有。因此，我必须通过编辑/etc/resolv.conf文件并重新启动网络来手动执行此操作。

# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
nameserver 8.8.8.8
nameserver 8.8.4.4
# DOMAIN=lab.foo.com bar.foo.com

这解决了这个问题。
