My problem is that it cannot automatic switch to the new Wi-Fi network. I need turn Wi-Fi off and on. Is that normal?

Gray status bar icons

What does it mean when the wifi and cell signal icons in the status bar are grayed out? Because that happens to me a lot.

It means you aren't connected to google's server.

Which usually mean your phone is not acting like it should be.

Or you don't have a data/internet connection on your phone.

I was having this issue a lot today at work, but I was using my old cut sim. I got a new microsim from tmobile today so hopefully that fixes it

You can have grey bars and still have a data connection.

This. It means you still have a data connection, but not a current connection to Google's servers for syncing to their services.

I had no idea. Is there a reason why this would be happening?

[Q] Wifi connection problems

I can connect to my wifi router fine but the icon is gray instead of blue and i believe this means limited connection. Not really sure what to do next. All my other devices connect to the wifi with no problem at all so it shouldn't be the problem with the router.
It means your not connected to Google

How do I change the setting where WiFi stays connected if on charger? Or is this already the default?

Turn off wifi and mobile data from settings will not do it for you?
Sent from my Nexus 4 using xda premium
you can delete(copy first please) any number of wifi related files with a root file explorer out of /sys/ or /system/(and reboot) which would essentially incapacitate wifi. then either reflash your rom/kernel/ or put the files back.
Their has been some pretty fishy posts lately....

Just use airplane mode, no???????
Edit; oh, thought he meant all data
Then you can't get calls or sms

Airplane mode.. Lol

You could just not turn on WiFi.

You can get WiFi to stop working, You will have to modify the kernel.
Delete the following folder in the last directory:
/sys/bus/platform/WLAN_CTRL
/sys/bus/platform/wcnss_wlan
/sys/kernel/ipv4
I am not sure why you want to do this even if there are other safe ways to stop this interface.
What you are doing is really dangerous and can cause a soft brick causing you to reflash everything using the Google Developers Nexus flashing tool.

Wifi issues.

Hello everyone,
I finally got my S5 last week but I seem to be having wifi issues.
For example at work. I'm connected to the wifi but i dont seem to have a internet connection. With my S3 i never had this problem.
Any ideas what this might be?

Go to your WiFi settings, then advanced, and turn off Always allow scanning.
I already had that turned off but thanks for the suggestion
