Why is explanation mark on Wifi symbol

The exclamation mark at the Wifi symbol means that the device is connected to the WLAN but no connection to the internet.

First I would recommend to turn off and the on the Wifi on the device.

I think it sometimes has to do with a bad DHCP leas.

This happened to me yesterday on one tablet running Android 6.0 without issue for the prior 2 months on the same network, and my other 4.4.4 devices say nothing is wrong with the network, router or Wifi configuration.

On examining the Xfinity router, it appears Xfinity pushed a new configuration to the router over the past days, as it has new software and the error appears on all Xfinity powered networks on the problem tablet.

The tablet remains surfing without restrictions on Internet despite saying "Connected, No Internet". Its annoying as much as the "!" suggests something is wrong, but the bigger annoyance is Wifi has to re-selected every time the Tablet is turned on again, it can't connect automatically.

I think this both a bug and a legitimate warning of an issue because after I fixed mine, I removed the fix, and the "!" remains OFF.

For example, it works correctly on captive portal wifi such as in McDonalds or Starbucks.

I think the "!" appears with too many possible issues, its very non specific.

There are many solutions.

I tried the typical ones, turning the router off/on, device off/on, resetting wifi off/on etc., nothing helped.

This is finally what worked:

1. Go to "Settings"

2. Go to "Data Usage"

3. Go to drop down menu in the upper right hand corner (:)

4. Go to "Network ...."

5. Toggle ON/OFF what ever setting you see there.

6. Optionally return it to the setting you found to see if its a 'bug'

Its a variation of what was posted here:

it may be that the network administrator has denied your device access. Have them find the MAC address of your phone/laptop on their network and allow access

Power off device, removed SD card and sim card. Reinstalled both and restarted device.. wifi connnected after entering passwords that were previously saved. Lost all saved wifi passwords but that’s ok.

so simple.. Go to wifi settings>advance>static> change dns 2 to 8.8.4.4 .. mail me if working

This happens when your phone thinks that there is no internet over the wifi connection. Turn wifi off, then back on. Sometimes this fixes it. If it doesn't then you may need to reset your router and/or modem.

I only started having this problem when I found out my neighbors were hacking in to my wifi. Had to have updated security put on for all my devices! So many scammers out there buying different tech items so they can jump on your wifi. They can buy all kinds of stuff to scam you but don’t want to pay

the buck for their own service. So far I am no longer seeing the question mark. I would recommend you check and update all your security on all your devices. I hate scammers I tell them to pay for their own SH—! Hope this helps!!!
