Wifi connected but no internet, no fallback on mobile data - Redmi K20 / Xiaomi Mi 9T Questions & Answers

9T, latest MIUI 10, I have basically all the wifi networks on "automatically connect" option, since they came from google backup from another phone.
Lots of them are without password and require a browser auth, and until you do not do this auth, you have no internet.
On every other phone I had (OnePlus, samsung,...), if there is no internet on wifi, the mobile data stays on.
On this Xiaomi no. It connects to the wifi, it says no internet, but mobile data are kept off since the wifi connection. Wifi Assistant turned ON.
This is very bugging me, since there are lots of wifi with this authentication around the city and sometimes I do not receive messages for 10/15 minutes for that because the phone connects to a wifi that require auth. The only way is setting that wifi network to not automatically connect and then disconnect from it, but I discover it only when I pick up the phone from the pocket.
Already tried to clear network setting (now I do not have any wifi network saved), but the issue persists, if I connect to a wifi and I do not authenticate via browser, I have no data because the mobile data are kept off.
Is it a bug?

The WIFI without the GPRS (3g)

Hello,
I need some help about my htc hd.
I want to ensure that, then i connected to internet via WIFI, my GPRS (3g) is not connected.
How can i disable the 3g GPRS connection, and enable WIFI only
Thanks a lot!!!
No Data will allow you to stop data connection.
so now if i closed my Orange network, the WIFI should work?
It is still doesnt work, do you have any idea how to configure it?

Course it will there seperate
All you do is block Orange connection when you want and unblock when needed
This program doesn't help me , because even i close it the GPRS still work.
But than i take the SIM from the phone, or turn off the phone feature, the internet connection is unavailable.
I think that all problem that was in some topics about the WIFI speed , is because of they used the GPRS internet and not the WIFI.
So , there some more complexive problem with internet WIFI in HTC HD.
Just try to take out the SIM and than surf in internet with WIFI? There is no way!!!!!
the connection icons on the top of the screen clearly show which data connection is active
the manual describe the meaning of all the top screen icons
settings->connections->connections->advanced-select network
pick my home network or whatever the non isp connection is named on your phone
and all data connections when there is no wifi or activesync connections to get free network from will fail with an error == you will never get a grps connection again
before you turn it back to my isp or what it's named on your device

[Q] Guest Wifi Timeout

At my place of work, the open/guest Wi-Fi times out after about 1 hour, which requires re-authenticating through a webpage. When my connection to the network times out, my N4 graciously notifies me that I need to sign in to the network again. This is all well and fine. My question though is, why does my N4 continue to try to use the Wi-Fi connection if I have "Avoid poor connections" checked under the Advanced Wi-Fi settings? This setting indicates that it won't use a Wi-Fi network unless it has a good Internet connection. I would like to use the Wi-Fi, but when the connection is no longer available, I would like my N4 to start using the mobile network...is this possible?

Use LTE while connected to WiFi Camera

So, I recently got a camera that connects to my phone via WiFi to use as viewer. When connected to the WiFi camera, I can't surf the internet. I figured when the phone didn't detect internet connection through the WiFi it would use the mobile/LTE connection for internet. This seems to not be the case. Does anybody know of a way to force using the mobile/LTE connection while the phone thinks it's connected to a WiFi network? Thanks in advance.
Put the wireless camera on a network and get remote access to it or use download booster which should work as a back up internet
Thanks for the suggestion. I can’t put the cam on the network, it doesn’t have an interface. All settings need to be adjusted through the phone. It’s a Xiaomi MiSphere.
Download booster, on the other hand, is worth looking into. I took a hiatus from Android for a while, just got back into it with the GS8 so relearning things.
If I understand your question correctly, the phone connects directly to the camera via WiFi. So as far as the phone can tell, the camera is a router with no internet connection.
I have the same problem.. I need to connect to my car via WiFi without internet connection, but I want to stay online via mobile network. It has worked well on my previous OnePlus 3 with the stock rom, but SGS8+ doesn't support this feature. I have tried to turn on "Keep Mobile data turned on" option in "Developer options", but it isn't helpful. The Mobile Data is on while connected to the WiFi, but the Internet connection doesn't work via Mobile network. Google Chrome and all other apps say, I am offline without the Internet.
Any solution?
Any possible solution for this issue?

Internet while connected to local WiFi

Samsung allows a phone to use it's mobile network to connect to the internet while it is also connected to a non-internet wifi connection. That doesn't seem to work with my OP 8 Pro. I contacted their support and they told me to try Dev Options and turn on Mobile Data Always Active and Aggressive Handoff.
I turned on Mobile Data, but the other setting does not exist (I've got 11.0.5.5). Replies to their support have gone unanswered.
When I connect to a local WiFi device (without internet) the phone will popup a notification informing me that it does not have internet connectivity and allow me to choose if I want to stay connected or not. If I say no, it drops the connection. If I say yes, I stay connected to the local WiFi, but cannot access the internet (mobile data is on and has signal).
I'm not sure why this is so hard.
Has anyone figured a way around this there are lots of times when it's necessary to be connected to both especially with devices like marine navigation systems.

Mobile Data Always Active doesn't seem to work

I tried searching and couldn't find anything. The problem I have is that if I connect to a 'private' wifi network (no internet on the wifi network) I can no longer access any sort of public resources. It has been suggested to me that the 'fix' for this is to go into the developer options and set 'mobile data always active' to 'on' . However this doesn't work. Has anyone else had this issue? Is there a way to fix it?
No, not connecting to the wifi network isn't an option, and neither is 'disconnecting' when I need internet and then reconnecting afterwards. I really need to have my data served by the mobile network while also connected to a device via wifi.
