XpressReal T3 + Quectel 4G LTE
燧炻创新 XpressReal T3和移远4G LTE模块，拨联通卡入网成功。
虽然用的是minipcie槽，但明白人都清楚，wwan模块走的一般都是usb引脚，所以这种模块用到的pins其实并不多。
连接成功无鸭梨，拿到联通NAT地址：

看起来差不多有50Mbps左右的下行，考虑到身处环境结构复杂的写字楼内，这个水平还ok是吧。

过程就不多写了，有 ModemManager 和 NetworkManager 两个服务就ok，不像多年前的拨号还要切换模块状态啥的。

nmcli 列出设备，再建个连接就行：

还记得我之前写的使用RPi 4b加工一个双wan冗余路由对吧？换用这块尺寸更具优势的XpressReal T3，也会是一个好玩的解决方案。
哦对了，它armbian还没提供kvm support，如果想做路由可以先手打iptables/nftables顶着，一定要玩openwrt的话，也可以搞incus container版本先跑起。
