I use a WLAN access point TP-Link TL-WR841N with "broadcast SSID" disabled.

Setting up the WLAN connection between my jolla phone and this device works and I can use it flawless. But after rebooting my jolla phone, my jolla phone seems not to be able to connect to this WLAN again. Access data to this WLAN (SSID and password) is still stored under Settings -> System -> WLAN, but there is no connection.

Disabling and reenabling WLAN on my jolla phone did not solve the problem: My secured WLAN keeps disconnected.

I found out, that enabling SSID broadcast on my WLAN access point is a way to work around this problem. But it would be nice if "hidden SSIDs" would work flawless, too.

I found other people mentioning problems with hidden ssid in comments to other questions:

• https://together.jolla.com/question/9125/data-connections/ (comment by found_Irish)
• https://together.jolla.com/question/35169/bug-10420-closed-settings-app-crash/#post-id-35191

But since I could not find a separate question for this, I decided to open one.

I use version 1.0.8.21 (Tahkalampi) at the moment. And my jolla phone is the only WLAN device connected to the accedss point.

Workaround: Deleting and adding the WLAN connection again, brings back full WLAN functionality in such a case (Thanks to @Aashish and @sifartech). But you always have to enter SSID and WLAN key (or at least copy&paste it from a text file on your jolla phone). So this is kind of uncomfortable.

UPDATE: This problem still exists in 1.1.7.27 (Björnträsket). Not after every reboot but it has happened to me at least once a week recently. Unhiding the SSID temporarily works as a workaround.

Update, 23.01.2016: In the meantime, I have updated my jolla phone to version 2.0.0.10 (Saimaa). And this bug seems to be fixed by now. I don't know, whether it was fixed in the update to version 2.0.0.10 or a version before, since I did not test it against all SailfishOS updates.

I tried the following usecases:

1. keep WLAN router running and rebooting my jolla phone => jolla reconnected WLAN flawlessly
2. shutdown WLAN router, shutdown jolla phone, start WLAN router, start jolla phone => jolla reconnected WLAN flawlessly
3. shutdown WLAN router, reboot jolla phone, start WLAN router => jolla reconnected WLAN flawlessly

So, I would say, we can close this bug report. Thanks to SailfishOS developers for fixing this! :)
