Answer by vision for [3.1.0.11] No more WIFI connection [Jolla 1]

I just have tested the WIFI connection on one of the Jolla 1 phones and I don't have any issue with accessing web pages or downloading app updates via WIFI. The 3.1.0.11 update was done via the update page in settings. So at least in my case I can confirm that WIFI is still working on Jolla 1 with 3.1.0.11. Can you try to check WLAN with CSD tool?
