Virtual Wifi

Virtual WiFi [Experiment in ReDroid 10]

ro.kernel.qemu.wifi=1 Virtual WiFi is still under development, make sure mac80211_hwsim exist (modprobe mac80211_hwsim).
checkout redroid-10-wifi in vendor/redroid and redroid-10.0.0 in device/generic/goldfish to make your build.
run docker exec <container> ip r add default via 192.168.232.1 dev wlan0

Inside device/generic/goldfish I can only find official Android branches.

Do I need to git remote add redroid https://github.com/remote-android/device_redroid?

I cannot find this branch redroid-10.0.0

[zhouziyang]

you just need vendor_redroid. I'm still refactoring repos, and move device configs to device/redroid and leave module definition under vendor/redroid across all versions.

Any suggestions on this for redroid/redroid-10-wifi?

seems permission issue (use root user to build before?).

[sickcodes]

Yes I did use root, didn't think it would be a problem. I'll try as a subuser.

[Dinibewerbig]

Somebody got the Wifi working at this stage?

[zhouziyang]

@Dinibewerbig already got a POC working on redroid-10. all you need is mac80211_hwsim kernel module, and it;s same as android emulator.

Hi,
I didn't find the image redroid-10-wifi. Was it removed?
I'd like to run an app (Sonos S1) which insists on having wifi and localization enabled on the device, even when they're of no use.

[zhouziyang]

I remove this branch in several repos since build broken.
It's feasible to emulator WiFi in redroid based on mac80211_hwsim kernel module. But still recommend to use Android Emulator based solutions if full emulated WiFi needed.

As a workaround, can mock WiFi NetworkInfo with Ethernet NetworkInfo; And App will think it's WiFi connected.

Thanks for the hint. Unfortunately I don't know the codebase enough. Would you mind adding a few more details?

This line is already present in the source code. So I guess it has no effect on my use case, unfortunately.
