WiFi Connected But alert "Connected without Internet"

[Gian774]

Dear all,

all Samsung mobile have some issue with our wireless network.
The devices are connected (IP, GW, DNS as expected) but there are an alert "!" with the message "Connected without Internet". Chrome works and Internet is available!

What tests do Samsung devices perform to verify Internet connection? Iphone, Xiaomi,... work without alert.
(Maybe the firewall or URL filter block the test)

Thanks in advanced

Hi found this but I think is not correct or up to date

You should be able to connect your phone to your WiFi router like any other device

Have you modified the router settings? Maybe a factory rest of your router will be easiest way if config has been modified

I'm able to connect (I receive IP, GW and DNS).
Internet is working but the users read on device "Connected without Internet".
My question is: how Samsung devices  determine if a device is connected to the internet?

thanks

I am guessing like any other device, is it sees traffic over the connection

[Gian774]

if the internet works there is traffic! but that's not the question

My question is: how Samsung devices  determine if a device is connected to the internet?
My goal is not to have the message: "Connected without Internet".

I did answer you question, it detects any traffic over the connection.

Was your question not "how Samsung determines if device is connected to the Internet?"

[Gian774]

ok sorry. However the Internet is working (4G disabled), why do we see the message?
Is Samsung using the standard Android check?

We have a firewall,  URL filter and SSL Inspection on some URL Category (certificate installed on the devices).

That's OK, not to worry

It should just do standard checks, when I issue before I just restarted my router and seemed to connect

Is the firewall in the router on additional? If additional you need to check your config

Are you able to still browse even with that error?
