Where is my internet access icon?

[AC Question]

No internet access icon

At home, I am running IPFire firewall + OpenDSN and it block access by IP and has excessive filtering.
After upgrade to new Android OS my phone displays no internet option but I can browse websites without any problems with my data turned off.
Can you tell me which you URL or IP address nexus 5 uses in order to check for network connection.

I have 4 nexus 5 phones. all connected to the same N network, two phones updated to OS 6 and two running OS 5. on nexus 5 phone, regular wifi icon on nexus 6 phones wifi icon and exclamation mark. I can access internet on all phones

Re: No internet access icon

That's an interesting issue. Have you reset the router? Perhaps that fixes the no internet error.
