I believe it works like this:
1) Wifi is activated.
2) Kobo device tries to 'phone home' or test the connection by accessing an url
3) If there is no reply, or a refused connection it decides the connection is useless and shuts down the wireless.
In my opinion this is a serious bug, because wireless should work even if their site is not reachable. For example when you have a
captive-dns solution that's popular in hotels. You buy a username and password to enter on their web page portal before getting access to the outer network(internet).
Kobo Mini:
2.8.1:
No plugins or files necessary:
Steps to reproduce:
- Attempt to connect with a wifi accesspoint that does not give internet access.
Current result: Wifi is disconnected prematurely
Workaround: None currently
You can simulate or test this by unplugging the uplink cable on a home router, you should notice a longer delay while the connection times out. If you work reasonable quick then you'll be able to verify that the device has gotten an ip address and is responding to pings. But when it finally the "something went wrong" is displayed the wifi radio is shut down.
