If your home or business is keeping wireless devices connected through a Google Wifi, you'll be getting an update to the companion app today. The new version brings a pair of app shortcuts for those of us using it on Android 7.1 or above, but that's about it for visible changes. A teardown adds to the subject with hints of a new batch testing feature and settings for something called "port opening."

What's New

Unofficial Changelog: (the stuff we found)

  • Added app shortcuts (Android 7.1+)

App shortcuts

App shortcuts are hardly ubiquitous, but they're getting pretty common. Google Wifi joins the pack with a pair of new shortcuts of its own. The first launches directly into a speed test for your connection while the other opens the family management settings.

Teardown

Disclaimer: Teardowns are based on evidence found inside of apks (Android's application package) and are necessarily speculative and usually based on incomplete information. It's possible that the guesses made here are totally and completely wrong. Even when predictions are correct, there is always a chance that plans could change or may be canceled entirely. Much like rumors, nothing is certain until it's officially announced and released.

The features discussed below are probably not live yet, or may only be live for a small percentage of users. Unless stated otherwise, don't expect to see these features if you install the apk.

Batch test for all devices

The Google Wifi app will be getting a new testing feature that's designed to test the performance of all of your wireless devices at once. At least that's how it looks from new text in the app.

Multiple devices will be tested and a speed will be displayed for each after it is finished. A count of the total devices tested will be shown. It seems it will also be possible for devices to be skipped, probably if they are offline.

strings
<string name="wifiblaster_result_device_type_default">Wireless Device</string>
<string name="wifiblaster_result_loading">...</string>
<string name="wifiblaster_result_skipped">Skipped</string>
<string name="wifiblaster_result_speed_fmt">%1$s Mbps</string>

<plurals name="wifiblaster_devices_tested">
<item quantity="other">Devices Tested</item>
<item quantity="zero">Devices Tested</item>
<item quantity="one">Device Tested</item>
</plurals>

I'm curious how this will actually work in practice. A batch test seems like a great tool for determining if network performance is bad in a part of the house, but I'm not sure how quality will be assessed for all devices. Perhaps phones and tablets will only participate in the test if they also have the Google Wifi app installed, and all other devices will be left out.

Port opening?

The latest update to Google Wifi includes some new text and an activity for configuring something called "port opening." No, we're not talking about port forwarding – the practice of declaring a port that's visible to the outside world and mapping it to a device inside a network – this seems to be something else. The app already has settings for port forwarding, so it's pretty unlikely that some developer mistakenly added new terms for a feature that's already there.

I wish I could explain what port opening actually is, but in all the years I've spent configuring assorted networking hardware, I can't recall seeing that term used. I won't venture any guesses, but this could be related to just about anything.

strings
<string name="title_port_opening">Port opening</string>
<string name="description_port_opening">Manage port opening rules</string>

<activity android:name="com.google.android.apps.access.wifi.consumer.app.settings.advancedsettings.PortOpeningActivity" android:theme="@style/AppTheme.NoActionBar" />

Thanks to digitalcircuit in the comments, it looks like we've got an answer to this one. Port opening is mentioned in a Google support article. The context describes it as being similar in nature to Port forwarding, at least in that it allows users to open a connection to the outside world. However, since IPv6 doesn't use NAT, there are some differences between port forwarding and port opening, thus explaining the different name. – Thanks, digitalcircuit.

Google Wifi feature behavior with IPv6 (August 2017 software release only)

  • Port forwarding is something used with NAT on IPv4 networks, so it does not make sense to use it for IPv6 networks. However, any IPv4 port forwarding rules will remain in effect in Google Wifi. Port Opening functionality with IPv6 will be supported in an upcoming software release.
