虚拟wifi生效但app无网络 Virtual wifi works but no network for apps

[RongBeiJun]

我尝试按照readme启用虚拟wifi成功，但是任何应用都没有网络连接 I tried to follow the readme to enable virtual wifi successfully, but there is no network connection for any apps 设置中显示virtwifi网络连接受限，而在一些终端app（或者docker exec -it redroid sh）执行如ping 39.156.66.14时可以看到返回结果 The setting shows that the virtwifi network connection is restricted, while in some terminal apps (or docker exec -it redroid sh) you can see the return result when executing e.g. ping 39.156.66.14 请问您有什么建议或解决方案吗 Do you have any suggestions or solutions?

你用的哪个镜像？13的话我已经把captive portal server地址改成小米的了，如果你用的是12的话:

adb shell settings put global captive_portal_https_url https://connect.rom.miui.com/generate_204
adb shell settings put global captive_portal_http_url https://connect.rom.miui.com/generate_204

这样就可以解决无互联网连接的问题了 顺便，虚拟WiFi的DNS服务器指定的是8.8.8.8，检查一下你那边能不能正常访问。

which image you're using now? if redroid 13 then i've already changed captive portal server to xiaomi's. if you are using 12, you can switch to xiaomi's captive portal server:

adb shell settings put global captive_portal_https_url https://connect.rom.miui.com/generate_204
adb shell settings put global captive_portal_http_url https://connect.rom.miui.com/generate_204

then the "no internet" prompt will disappear.
BTW, DNS server address in container is 8.8.8.8, also check you can access that address.

感谢回复，这或许不是captive portal server的原因 Thanks for the reply, this may not be the reason for captive portal server 我在提issue后从orangepi的ubuntu更换到了Armbian_24.2.3_Orangepi5-plus_bookworm_legacy_5.10.160_minimal I changed from orangepi's ubuntu to Armbian_24.2.3_Orangepi5-plus_bookworm_legacy_5.10.160_minimal after issue 并且使用了cnflysky/redroid-rk3588:13.0.0-latest，在查看logcat后发现了一些关于iptables的错误 And using cnflysky/redroid-rk3588:13.0.0-latest, after checking logcat I found some error about iptables 我尝试修复了一部分（通过modprobe加载模块解决了如can't initialize iptables table 'nat'）但仍有部分未能解决 I tried to fix some of them (loading modules via modprobe solved e.g. can't initialize iptables table 'nat') but still some of them were not resolved （关于DNS 8.8.8.8，这里可以访问） (For DNS 8.8.8.8, access it here) 我对于虚拟wifi和iptables之间的工作方式不了解，我应该做些什么？ I have no idea about how virtual wifi and iptables work with each other, what should I do?

iptablesrestore报错是正常的，不用管 你关掉虚拟WiFi之后能上网吗？主机上切换到iptables-legacy试试？

iptablesrestore error is normal can you connect to internet after disable virtual wifi? also try switch to iptables-legacy on your host.

关闭虚拟wifi后网络可用（即docker run不使用androidboot.redroid_virt_wifi=1） Network available after turning off virtual wifi (i.e. docker run without androidboot.redroid_virt_wifi=1) 切换到iptables-legacy后问题依旧 After changing to iptables-legacy the problem persists. 在logcat注意到了一些内容create PF_KEY socket failed: Address family not supported by protocol不知道是否有关 Noticed something in logcat create PF_KEY socket failed: Address family not supported by protocol not sure if that's relevant 这意味我该只使用ipv4网络吗？ Does this mean I should only use the ipv4 network?

能提供一下你的内核deb包吗 我尝试在这边复现一下

can you provide your kernel deb package? im trying to reproduce your issue.

[RongBeiJun]

当然可以，链接https://www.123pan.com/s/G0EDVv-qWHKd.html Sure, link 因为超过25MB，限制上传 Limited to uploading because it's over 25MB 如果我的内核编译是错误的，希望您可以提供内核deb，或者告知我正确的做法 If my kernel compilation is wrong, I would like you to provide the kernel deb, or inform me of the correct way to do it, thanks

无法复现。操作步骤如下：

• 安装Armbian_24.2.3_Orangepi5-plus_bookworm_legacy_5.10.160_minimal 系统
• 安装你提供的内核包
• 重启
• 更换国内源(清华源)
• 安装docker sudo apt install docker.io
• 拉取镜像 docker pull cnflysky/redroid-rk3588:13.0.0-latest
• docker run -d -p 5555:5555 -v ~/redroid-data:/data --name redroid --privileged cnflysky/redroid-rk3588:13.0.0-latest androidboot.redroid_height=1920 androidboot.redroid_width=1080 androidboot.redroid_virt_wifi=1
• 复制Mali GPU固件 docker cp redroid:/vendor/etc/firmware/mali_csffw.bin /lib/firmware
• 等待系统启动完成
• 使用scrcpy，可以正常连接网络。

can't reproduce. steps:

• install Armbian_24.2.3_Orangepi5-plus_bookworm_legacy_5.10.160_minimal
• install kernel deb package you have provided
• reboot
• switch to Chinese debian sources
• install docker sudo apt install docker.io
• docker pull cnflysky/redroid-rk3588:13.0.0-latest
• docker run -d -p 5555:5555 -v ~/redroid-data:/data --name redroid --privileged cnflysky/redroid-rk3588:13.0.0-latest androidboot.redroid_height=1920 androidboot.redroid_width=1080 androidboot.redroid_virt_wifi=1
• copy Mali GPU firmware docker cp redroid:/vendor/etc/firmware/mali_csffw.bin /lib/firmware
• wait until Android boot up
• use scrcpy to stream screen, network is ok

您好，在您尝试复现问题的同时，我也在做其他的尝试 While you are trying to reproduce the problem, I am making other attempts 结果是app已经成功连接网络 The result is that the app has successfully connected to the network 成功的尝试的环境如下 The environment for a successful attempt is as follows 系统为Armbian_24.2.3_Orangepi5-plus_bookworm_legacy_5.10.160_minimal system is Armbian_24.2.3_Orangepi5-plus_bookworm_legacy_5.10.160_minimal 开启mac80211_hwsim的内核 Enabling the kernel for mac80211_hwsim docker run部分依然遵从readme（但使用cnflysky/redroid-rk3588:13.0.0-latest） The docker run part still follows the readme (but uses cnflysky/redroid-rk3588:13.0.0-latest) 保证只有无线连接（猜测此项为问题主要原因，此前有线连接与无线连接同时存在并且连接在相同局域网） Ensure that there is only a wireless connection (guessing that this is the main cause of the problem, as both wired and wireless connections existed and were connected to the same LAN earlier) redroid中app网络可用 network availability

请问如何保证只有无线连接，我也遇到了相同的问题。 May I ask how to ensure only wireless connection? I have also encountered the same problem

将主机切换到iptables-legacy随后重启 或 使用sudo modprobe iptable_nat加载模块，之后再创建容器。已经加到README里面了。

switch to iptables-legacy in your host os or sudo modprobe iptable_nat load nat module, then create container. added to README.

理论上，可以通过在framework层对connectionmanager类进行改动，使其对app返回一个虚假的WiFi连接以达到虚拟WiFi的效果。但是由于本人不擅长Android开发，只能搁置。如果有哪位大佬愿意帮助，欢迎PR。

It's possible to implement Virtual WiFi through this way: return a fake WiFi connection by patching into ConnectionManager class in AOSP Framework. but I don't know how to do it. PR is welcomed.
