我在新款联想 Thinkpad X260 笔记本中安装调制解调器时遇到了一点问题。调制解调器的型号是 Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A，操作系统是 Ubuntu 16.04。
在 Ubuntu 的登录屏幕上，我弹出一个输入 PIN 的窗口，因此我已禁用手机 SIM 卡的 PIN。这是 2017 年 5 月下载并安装的全新 Ubuntu 安装，没有安装任何其他东西，只尝试运行调制解调器。输出是
移动宽带 - 未在网络管理器中启用。
我曾尝试在设置 > 网络 > 移动宽带，但创建后，无法再单击它，它不会显示在任何地方。当我单击网络管理器时，我可以通过以下方式创建新网络编辑连接，但同样，这个新创建的连接没有列在任何地方。我也尝试了一款名为 Sakis3G 的软件，但没有成功。我不想因为这个而切换到 Windows。
我在某处找到并尝试过的东西：
我做的第一件事就是将 SIM 卡插入手机。互联网在那里工作，并且我已禁用卡上的 PIN。此外，我在 Windows 7 和 10 中测试了调制解调器，它在两种系统中都可以正常工作。
我创建了一个包含以下内容的文件
/etc/udev/rules.d/99-sierra.rules：ACTION!="add|change", GOTO="mbim_to_qmi_rules_end" SUBSYSTEM!="usb|drivers", GOTO="mbim_to_qmi_rules_end" # load qmi_wwan module SUBSYSTEM=="usb", \ ATTR{idVendor}=="1199", ATTR{idProduct}=="9079", \ RUN+="/sbin/modprobe -b qmi_wwan" SUBSYSTEM=="usb", \ ATTR{idVendor}=="1199", ATTR{idProduct}=="9079", \ ATTR{bConfigurationValue}="1" # add the new id in the qmi_wwan driver SUBSYSTEM=="drivers", \ ENV{DEVPATH}=="/bus/usb/drivers/qmi_wwan", \ ATTR{new_id}="1199 9079" # load qcserial module SUBSYSTEM=="usb", \ ATTR{idVendor}=="1199", ATTR{idProduct}=="9079", \ RUN+="/sbin/modprobe -b qcserial" # add the new id in the qcserial driver SUBSYSTEM=="drivers", \ ENV{DEVPATH}=="/bus/usb-serial/drivers/qcserial", \ ATTR{new_id}="1199 9079" LABEL="mbim_to_qmi_rules_end"我在文件底部添加了
/etc/modulesusbserial vendor=0x1199 product=0x9079我创建的
/etc/usb_modeswitch.d/1199:9079内容为：DefaultVendor= 0x1199 DefaultProduct=0x9079 TargetVendor= 0x1199 TargetProduct= 0x9079 CheckSuccess=20 MessageContent="55534243123456780000000000000606f5 0402527000000000000000000000"
一些命令的输出：

答案1
我也遇到了类似的问题，唯一的区别是我有一台 Fibocom Cat6 L830-EB 4G LTE。
我不知道这是否对您有帮助，但我已解决从 Ubuntu 软件中心下载“调制解调器管理器 GUI”的问题。
我有一台装有 Ubuntu 16.04 LTS 的 Thinkpad T480。希望这能对大家有所帮助。
答案2
我在使用 Linux Mint 18.2（Ubuntu 16.04）时遇到了类似的问题
1）将 16.10 源添加到 apt
2）从源代码安装modemmanager-1.6.0及其依赖项
# cd /usr/src
# apt-get source modemmanager {libmbim libqmi}
# apt-get build-dep {*}
# cd {*} ; dpkg-buildpackage
3）现在就可以工作了:-)
