虚拟wifi开启后能连接到wifi但是上不了网（default route缺失?) #4

docker run -itd --rm --privileged \
        --pull always -v ~/data:/data \
        -v /dev/mali0:/dev/mali0 \
        -p 5555:5555 \
        iceblacktea/redroid-arm64:12.0.0-240328 \
        androidboot.redroid_gpu_mode=mali \
        androidboot.redroid_virtual_wifi=1

启动后能看到ChinaNet等4个wifi网络但是连上后都显示无法提供网络。

看了下ip route是这样的：

192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.2
192.168.200.0/24 dev radio0 proto kernel scope link src 192.168.200.2

但是如果手动加上default route就可以正常上网了 ip route add default via 192.168.1.1

作为对比如果启动时不加redroid_virtual_wifi=1好像就会自动生成一条default route规则，这时虽然没有wifi但是可以正常连接网络。

请问下default route缺失是预期的吗，可能是啥问题

ice-black-tea commented 4 months ago

理论上有默认路由才对

$ ip route show table wlan0
default via 192.168.1.1 dev wlan0 proto static
192.168.1.0/24 dev wlan0 proto static scope link

dhcpserver分配给wlan0的信息都对吗

这个应该怎么看

Frefreak commented 4 months ago

asdf.log 这个是logcat输出，14:26:21的样子有尝试切换到"CMCC"网络，但还是没有default route

你那环境相较于我的环境确实少了default route，后续版本我脚本里主动添加一下default route来解决这个问题吧

hjxcode commented 3 months ago

你好，我也遇到了这个问题，请问解决了么？我的现象是显示连接wif，正在获取ip，但没办法真正连接上，容器内的route也是只有一条 image

虚拟wifi有下行网络，没有上行网络？
