我最近在笔记本电脑上安装了 Ubuntu 14.04。我有一个 LAN 连接,需要拨号才能输入 ISP 提供的用户 ID 和密码。
请注意,我没有路由器/调制解调器。在 Windows 中 LAN 运行良好。
我尝试过以下方法:
- 使用传统的网络管理方法显示已建立连接,但没有互联网连接
使用
gnome-ppp
结果为:Cannot open modem
使用
pppconfig
&pon
/poff
表示以下任一情况:dwarkesh@radhe:~$ pon dwarkesh dwarkesh@radhe:~$ plog Mar 11 23:33:41 radhe pppd[2858]: Plugin rp-pppoe.so loaded. Mar 11 23:33:41 radhe pppd[2858]: Plugin /usr/lib/x86_64-linux-gnu/pppd/2.4.5/nm-pppd-plugin.so loaded. Mar 11 23:33:41 radhe pppd[2858]: pppd 2.4.5 started by root, uid 0
或这个:
dwarkesh@radhe:~$ pon comcast dwarkesh@radhe:~$ plog Mar 11 23:39:19 radhe pppd[3107]: pppd 2.4.5 started by dwarkesh, uid 1000 Mar 11 23:39:20 radhe chat[3109]: Can't get terminal parameters: Input/output error Mar 11 23:39:20 radhe pppd[3107]: Script /usr/sbin/chat -v -f /etc/chatscripts/comcast finished (pid 3108), status = 0x2 Mar 11 23:39:20 radhe pppd[3107]: Connect script failed Mar 11 23:39:21 radhe pppd[3107]: Exit.
使用
wvdialconf
&wvdial
,显示:Cannot open /dev/modem: No such file or directory
