Why is explanation mark on Wifi symbol

There is an explanation mark on my WiFi symbol on top of my phone. I now can NOT connect to the internet even though phone says I'm connected to my home WiFi. I have read tons of things online where this is happening to all kinds of different types of phones and carriers. Apparently has something to do with Google. None of the ways listed to fix this had worked on my phone. Can anybody tell me why this suddenly started and how to fix it??

Does this only happen on your Home WiFi network?

As far as I know yes, but haven't been anywhere to really know.

Also internet is working perfectly right now. Makes no sense at all.

Here, try this Youtube : https://www.youtube.com/watch?v=DpFx4AQC...

My problem was our router..

I'm having the same problem on my phone however it started after I removed the family base mobile app form my phone. Did you also happen to have that app on your phone? And have you found a solution?

Hi @mom2javas

If you have a PC connected to the WiFi network you could try downloading, installing and running a WiFi scanner program such as inSSider to see how many other networks in your area are sharing the same WiFi channel. (Do not worry they are not sharing your PC etc only the channel. Like sharing the road, the more cars in the same lane the slower you go). As most routers default to channels 1 or 6 it could be that if their signal is relatively strong enough that they are causing interference to your connection. Try switching your router to a 'quieter' channel, i.e. one with less or no appearances in inSSider and see if it helps.

Here is a link to the program. There are a lot of other WiFi scanner programs available if this doesn't suit. At least this version is still free.

I am only saying to do it this way as I am not sure if there is an Android app that does the same thing.

Hi @akorn40205,

Can you get internet on the phone?

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.

I have turned it off and on as well as many other things I've read other people have done that fixed it for them, but so far nothing has worked for me. Thank you for your reply Claes

I had ones case a few month ago where no portable device would connect to the internet. That time I had to reset the DNS and delet all DHCP leases. How easy that is on a router I do not know since I did it on my Windows Server 2012 DHCP server.

Also internet is working perfectly right now. Makes no sense.

I have a Samsung Galaxy S7 active, Android 7.0. I am experiencing this issue as well. I have tried restarting my phone, restarting my router, making my phone "forget" the network and re-connect. It does it at random, no pattern at all. My router is Motorola Surfboard.

Any suggestions?

@torturedoranges Have you lookedin the menuof your Motorola Surfboard if there are any DNS or DHCP settings you can reset or renew leases?

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.

https://en.wikipedia.org/wiki/Captive_po...

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.
