I bought my Nexus 5 back in February and have never had issues with it till 3 weeks ago. Wifi worked fine everywhere and one day at home it stopped working. It keeps showing that is connected but internet does not work. A couple of weeks later the new Android Lollipop roll into my phone and I hoped that would solve the issue, unfortunately it still does not work at home. At my work place it connects with no issues, so I assume is the phone because it worked for 6 months and before the android update at home, and nothing has been changed/updated in my router. I've tried everything you have posted in this thread and in other websites, however the only thing that helps temporarily is changing the channel in the router, but every time I go out and come back home, I have to change the channel once again. This is something that works once in a while and not all the time., What device do you have? There seem to be two problem: (1) your wifi connection gets dropped from your home wifi network, and (2) it keeps trying to connect to an open wifi network. For problem 1, have you gone through the various tips in the main part of the guide? Turn off wi-fi optimization, and turn off any option that avoids a weak signal., Hi folks, I recently bought a Samsung Galaxy S 10.5 but I'm finding that the Wifi performance is fairly ropey if bluetooth is also being used, has anyone else experienced this?.
