No internet connection

[Amura]

since rcently my Sony Xperia Z5 often refuses to pick up the WiFi connection in our house while other devices work fine. The WiFi says 'Connected, no Internet '.

Sometimes it helps to refresh or switch phone off and back on, but often that doesn't do the trick either. Any idea??? Thank you!

Happened to me every now and then for a long time. Not sure if bad firmware or hardware.

I had the same issue. The internet connection was broken for between 5-20 second whenever i connected with wifi although there is no other prolem. I restarted the network settings and it worked well for a short period. Now i have same problem!
