Following on from the first symptoms identified in this post I have finally concluded that there is some issue with the Wi-FI / Internet connection on Xperia X in some countries only when using Sailfish OS. I first witnessed this issue upon arriving in the Asia Pacific countries. Everything was working fine before I departed my home European country. The Sailfish OS version at that time was 3.0.2 Oulanka. I have since re-flashed fresh images of and Hossa, and still the problem occurs.

The problems identified are:

  • Unable to browse to any websites with the Sailfish Browser.
  • Unable to download apps from the Jolla Store.
  • Unable to use any other store
  • Jolla apps (e.g. Weather) will not connect to the Internet to update or fetch related data.
  • After fresh installs, the Jolla apps cannot be installed because they cannot be downloaded from the Jolla store.

Basically, the issue is with any kind of Internet activity over the Wi-Fi network. I can establish a connection to the Wi-Fi networks without any problem, but no connection to the Internet. In some rare cases, there will be some extremely weak Internet activity where, for example, the browser may load some webpage elements but not entirely. This weak connection usually lasts no more than 90 seconds before it completely ceases and results in network connection timeouts. Another example is the Jolla Store app being able to fetch the description of another app, but not be able to download it. I'm not using a VPN or proxy of any kind.

I've tried multiple Wi-Fi networks - at home and at work where I have access and control of the router configuration. I've also tried public networks - at the gym, in bars and at restaurants; all at different locations, all with the same result. Wi-Fi connection is established, but no connection to the Internet. At first, I suspected damage to the wireless hardware in the Xperia X, but that's not possible if it connects successfully to the router. The Internet connection is the issue. My other devices (laptop, Android phone) connect to the Internet without issue.

I have just reverted the Xperia X back to the latest Android 8.1 image using the Emma Tool on a Windows PC. As soon as I connect to the same Wi-Fi networks as before, the Internet connection works, is stable and super fast. Chrome browser has no problem with any website, nor does any other browser (Firefox) or store (Aptoide, F-Droid), which I also happened to be using (and having trouble with) in Sailfish.

How can this possibly be? I have never heard of such an issue. The network environments and hardware all remain the same. The only thing I've changed is the device OS. I can't even explain the theory behind why this wouldn't work, unless ...

All Wi-Fi / Internet data sent/received via the Xperia X on Sailfish OS is passing through some server (Jolla?) first before being sent to its destination. As a potential Jolla server is likely to be located in Scandinavia, that would explain the extremely high latency and connection timeouts I receive on the rare occasions I receive a weak Internet connection for the short time period (max. 90 seconds). It also supports why I do not have any such problems with the original Android image being restored to the device, as there's no Jolla services present.

But surely, this couldn't be?

@jimjamz my wifi at home works. your description is a little bit confused
Do you mean wifi public hotspots ? =>
In which country are you ? or you observe it? with private wifi or public hotspots

I'm currently travelling the Asia Pacific region for work. Not just public Wi-Fi networks (bars restaurants), but home and work Wi-Fi networks where I have access to the router configuration.

In a nutshell, using Sailfish, I can connect to the Wi-Fi networks here but there is no connection to the Internet in 95% of cases. In the remaining 5%, there will be a Wi-Fi connection for approximately 90 seconds or so where the connection is extremely slow/unstable (perhaps some text of a web page is returned but not enough bandwidth to return either the CSS or images) before it ceases completely. Reverting to the original Android image resolves this problen. No Wi-Fi or Internet connection problems of any kind. The bandwidth is super fast.

Updated the original post so it reads better. I didn't put enough emphasis on the issue being with the Internet connection being the problem, rather than the Wi-Fi connection being the problem.

Well. Exactly the same as you described above is happening to my xperia X. This issue wasn't in past OS versions, I'm sure. I'm from Argentina. I have this one since end of 2017. I'll make some tests and I'll let you know.

I'm facing this problem since Tuesday as well. With mobile network connection internet works as good as the German mobile network coverage permits. But using WiFi to connect to the internet has some issue. It's just not possible except for or Maybe some other websites work, but cant tell. Other web services like email, messengers, weather aren't working as well. My problem is definitely related to the installing of the Nanodroid version of PlayStore (which is a stripped version of the original). Funny enough, the same setup has worked with Now with I had to reinstall the stripped playstore and voila the internet problem started.

As mentioned previously, since reporting this issue, I have reverted back to stock Android 8.1 and have been able to connect the device to the Internet without issue, using it this way for some months now. However, I felt it necessary to try to reproduce the issue once again with Sailfish. I repeated the whole set of steps once more earlier this week, starting with the same version I used last time (3.03.10 Hossa). The same problem occurs as before. I can connect to the Wi-Fi but the device will not connect to the Internet.

I have since installed version Seitseminen and I can no longer reproduce the issue. The Wi-Fi and Internet connections are fine. This leads me to conclude that the issue was fixed in the recent update, to which hopefully the changelog will identify what it was that (inadvertently) fixed this.

Have you tried to reach a website by it's ip address? Your description sounds like a DNS problem, as you said connection to router works. Maybe their is a DNS server stored and not refreshed since you where abroad... Maybe you should also check routing table for faulty entries

The device was erased and re-flashed multiple times with Hossa. I would imagine any DNS entry would have been cleared with the re-flash. Flashing Seitseminen and the problem no longer exists. This concludes it is an issue in Hossa.
