My Nexus 5 ( 6.0.1, last patch installed dated March 1, 2016) doesn't recognize my home wifi anymore. It connects to my network, but says there is no internet (but there is). I tried everything (all the suggestions on Android sites, i.e. toggling plane/wifi/data on/off, shutting down/restarting the phone, deleting/re-entering the network, re-starting in safe mode, even reinitializing the network parameters... I went as far as resetting my router, changing the name and password of my network...) My phone connects to the wifi in cafés, and to my neighbour's wifi (open, no password). But with mine, all I get is "connected, no internet access" (while my computer is connected with access to the internet). What can I do now?
