我是 ubuntu 的新用户，使用笔记本电脑上的 Wi-Fi 宽带连接互联网。但我需要通过手机设置拨号连接，这样我就可以边旅行边上网。
我尝试使用 pppconfig、wvdial 和 gnome-ppp 进行拨号连接。我不知道它们是否使用相同的文件进行连接，但我只能使用 Gnome-ppp 进行连接。但连接断断续续，大约每五秒钟就会断开一次。退出代码是 16，我查看了 man 并得知调制解调器自动挂断了。
我正在将手机作为 USB 调制解调器连接到 Ubuntu。由于我是新手，我可能跳过了一两步。
请提出解决方案或替代方案。我已经记下了 Gnome-ppp 日志。
谢谢。

答案1
我已经通过从终端运行此命令解决了我的问题：
sudo chgrp dip /etc/ppp/*secrets
sudo chmod 660 /etc/ppp/*secrets
sudo adduser yourusername dip
sudo adduser yourusername dialout
运行gnome-gppp安装程序
出口gnome-ppp
然后编辑文件~/.wvdial.conf
更改行Stupid Mode = off至Stupid Mode = on
运行gnome-ppp并且不需要进行更多设置。
这对我 12.04 和 12.10 有效
答案2
只需使用sudo wvdial而不是wvdial。
答案3
我遇到了同样的错误。一位客户带来了他们的 Ubuntu 笔记本电脑。要求我将其更新到 12.04，并要求我添加 USB 调制解调器。所有操作都已完成。Gnome-ppp 看到了调制解调器，似乎可以正常工作。它连接后几秒钟就断开连接，并出现 PPPD 错误 16。我尝试使用 wvdial，但它不起作用。我尝试了“sudo wvdial --config=/root/.wvdial.conf”，它所做的与 gnome-ppp 相同。如果有人知道解决这个问题的方法，请与我分享信息，这当然是件好事。
答案4
我已经通过从终端运行此命令解决了我的问题：
sudo vim /etc/ppp/options
我删除了一些有冲突的 ID，/var/log/messages比如
11500
cat connect
braud
跑步gnome-ppp
这对我 12.04 和 12.10 有效
