Apple released a new software update for its series 3 watches today so as to upgrade watchOS 4 to watchOS 4.0.1. This is the first software update to watchOS 4 because it became available for all Apple Watch models on September 19. The watchOS 4.0.1 update focus on fixing a peculiar WiFi issue some series 3 with LTE models experienced. That issue prevented the devices from connecting to LTE in prefer of connecting to an inaccessible but familiar WiFi network.
The update page info the problem: “watchOS 4.0.1 fixes problems that, in rare cases, had been causing Apple Watch to join unauthenticated (captive) WiFi networks, along with those determined in public places like coffee shops and motels, which direct the user to a web page before the network can be accessed.”
Upgrade Version Apple WatchOS 4.0.1 Series
in the first round of Apple Watch 3 series reviews, some reviewers experienced this trouble. The series 3 attempted to connect with a WiFi network the user previously authorised and connected to through another Apple device (like an iPhone or a Mac). Public WiFi networks often make users accept terms and conditions or input temporary passwords before connecting. Since the Apple Watch cannot display those options, the series 3 could seem like connected to a WiFi network, even though no service came through. This prevented the series 3 from connecting to LTE service in areas where the user may have wanted to use mobile data over any WiFi network.
While I did not experience this specific problem while initially testing the series 3 with LTE, I had my personal unexplained (yet subsequently resolved) issues. Apple knew of this WiFi network problem soon into the review process and said it was looking into a fix that could are available a software update. WatchOS 4.0.1 is that update, and it’s only available for series 3 watches. No software updates are available for my series 2 watch, however, watchOS 4.0.1 is ready to download for my series 3 device.
To download watchOS 4.0.1, visit the Watch app on your iDevice and navigate to general, then update software. Your Apple Watch series 3 have to be connected to WiFi, placed on its charger and have at least 50-percent battery life to download watchOS 4.0.1.
