Debug on device documentation possibly incorrect.

Is this a bug report?

Maybe, either it's a bug or the docs are incorrect.

Have you read the Bugs section of the How to Contribute guide?

Yes

Environment

react-native -v:

react-native-cli: 2.0.1
react-native: 0.46.4

node -v:

v8.2.1

npm -v:

5.3.0

yarn --version

0.27.5

Target Platform: IOS
Development Operating System: MacOS
Build tools: Xcode

Steps to Reproduce

Run

react-native init
# or 
create-react-native-application 
npm run eject

Expected Behavior

Based on the sentence

You only have to be on the same Wi-Fi network as your computer.

From

https://facebook.github.io/react-native/docs/running-on-device.html

I assumed the device would attempt to connect to the packager.

Actual Behavior

It did not unless I hardcoded my laptops IP as jsCodeLocation in appDelegate.

I attempted clean builds, new projects, reset node cache, read several stack overflow posts and github issues.

It is still not clear to me whether this should work without changng jsCodeLocation or whether that is required, surely the docs should mention this if it is required?

It should work without specifying an IP address, this hasn't changed. The docs mention the following:

If you have any issues, ensure that your Mac and device are on the same network and can reach each other. Many open wireless networks with captive portals are configured to prevent devices from reaching other devices on the network. You may use your device's Personal Hotspot feature in this case.

Does this apply to your network?

Also worth noting, they also mention that this guide only applies to the react-native init way of creating projects (your issue mentions CRNA).

I've filed a PR for the docs with a troubleshooting section a while ago. If you follow the steps you'll most likely find the problem ... #14885

That does not apply to my network, I can connect just fine by hitting the packager in a web browser via wifi. This report applies to both ejected CRNA apps in Xcode and those created with react-native unit. I tried both. Sent from mobile.

Thanks @formatios will try this shortly and report back.

Let me see why that PR has not yet landed...

Sorry for late response, indeed the new toubleshooting helped.

In case it helps anyone else I am running DNSMasq on my DDWRT router, adding the following to my DNSMasq options resolved the problem.
