造成的影响包括但不限于

  • 没有熟悉的手机用
  • 无法使用 wlan
  • 时常报告 system 无响应
  • 无法使用 nearby share
  • 没有 android 14 的开发机用、

解决方案

1. usb 以太网

操作

  • 插个 usb 网卡就行了

工作 但在我工作区不适用 没有 rj45 接口

2. 蓝牙网络共享

操作

  • 连接蓝牙
  • 打开 互联网链接 选项

工作 但是速度很慢 因为蓝牙 5.0 可提供高达 2Mbps 的链接速度

3. usb 网络共享(RNDIS)

操作

  • 连接 usb
  • 打开 usb 网络共享

不工作 因为内核没有 RNDIS 驱动

4. tun socks5 in adb/usb

操作

  • 连接 adb/usb
  • 电脑 sing-box 里面跑一个 socks5 代理监听 tcp 10000
  • adb reverse tcp:10000 tcp:10000
  • 手机 nekobox 连接 socks5 127.0.0.1:10000

工作 还行但存在问题

  • 部分应用不走 tun 网卡 (termux etc…)
  • 活动依旧受限于数据线长度
  • adb 断开后需要重新配置

最终方案

结合 2 和 4

所以支持的应用会走 adb/usb 不支持的回退到蓝牙

踩坑

不要在镜像网络模式的 wsl 里跑代理 性能差到离谱

大概 adb/usb -> windows -> wsl 上行有 1.39 Gbits/sec 还看得过去

但 wsl -> windows -> adb/usb 下行只有 1.56 Mbits/sec 实属离谱

反思

  • 所以为什么不去修
    • 因为不敢去 社恐

感谢

咕咕华 不说我都忘了 vpn 是 tun 和 adb 能转发接口了
