[Q] WiFi Poor Connection Avoidance - Nexus 6 Q&A, Help & Troubleshooting

Hello,
Anyone else having an issue with their Nexus 6 device where if it detects a poor WiFi network, it will disconnect from it but in this state, it does not connect to your carrier's 4G/LTE connection? I know this used to be a feature you can enable or disable (Settings-> WiFi -> Advanced -> Avoid poor connections) but looks like this option has been removed from Android lollipop and instead is just enabled by default with no way to control it.
I noticed this when I walked outside my house and didn't have any data connection. When I went to my WiFi network lists it said "Temporarily Avoiding due to poor connection". It did not automatically connect to my 4g/LTE network, I even stood there for a few minutes to see if it eventually would. The only way to enable data was to turn off WiFi. As soon as I did that, it established connection with my carrier.
Screenshot attached.
Thanks!

[Q] Disable automatic WiFi connecting?

Is there a way to disable automatic WiFi connections when WiFi is on?
I was able to get around the automatic connection to my workplace's WiFi (they block sites and require a PC-generated pin to log in, thus I have no actual data if I forget to turn off WiFi) by checking that "Block Network Notification" box. I do have to connect to it at times which is the only reason I haven't forgotten the network.
But.. anytime I walk into a Starbucks, it'll connect to its WiFi network automatically. I went to AT&T Park this past weekend and it did the same thing (didn't realize until doing anything took forever). 4G/LTE is much faster than using these WiFi networks and I hate having to go in and turn off WiFi when I'm in public areas. I walk into range of these networks I don't know about and it automatically connects which is irritating.
Not sure about a built in setting to not connect to certain networks without forgetting them, but you could just put a WiFI toggle widget somewhere
I'm running the EQS from Android Revolution so I do have that option. Just hate when I forget to turn it back on when I get home.. lol

Well, you can always pull up the list of networks and long press each one. Then you can block it. Over time you will block all the places you generally go.

I figured I'd need to do that. Just wish it didn't automatically connect to WiFi networks I've never seen.

Question WiFi Problems

Hi community,
I'm writing because I have a strange WiFi problem with my S21 Ultra which I had with no other equipment before.
Setup:
- Galaxy S21 Ultra
- FritzBox 7590
- Fritz WLan Repeater 1750E (2x for better range coverage)
- WiFi 5G Auto channel WPA2/3
- WiFi coverage is good (tested with a lot of other devices)
Phone Setup:
- Paired with the WiFi
- Do Not use Mobile Data
- automatically reconnect to wifi
Problem:
The phone does not automatically connect to the WiFi.
The phone also looses the connection to the WiFi several times a day.
When the phone is not connected to the wifi I open wifi settings.
- It happens that the wifi list is completely empty and the circle animation indicates that the phone is searching for nearby connections
- It happens that the wifi list contains a list of wifi networks the phone has seen before when it was connected last to a wifi
- Switching off an on the wifi helps to find the actual networks and the phone then connects back to wifi (most of the time)
I tried already several settings and combinations but so far none of them brought any success. So I would like to know if someone else had a similar issue or has an idea what could go on here.
To me it seems strange that the wifi scan is not working as I would expect it. I would expect the phone to continously refresh the wifi list with networks it sees, but always when the phone lost its wifi connection the list is not working anymore.
Try tinkering with the wifi channels and encryption until it shows up.
Or you can try resetting the routers to see if it does anything

- Phone is on standby (placed on a table, etc.)
- I turn it on to check messages,
- No connection to wifi
- Open wifi manager
- No wifi networks listed at all
I do not know why my router/network should be the problem. All other devices in the wifi work flawlessly. It cannot be that I have to restart my wifi router every time the phone finds no wifi at all. That makes no sense to me.
It looks more like the android wifi service is still on sleep and does not report new wifi networks (which would be necessary also to see any wifi at all).
May I suggest....
Settings -> Connections -> Wi-Fi -> (three dots it top right) ->Advanced
Make sure "Turn on Wi-Fi automatically" and "Wi-Fi power saving mode" are both off.
If you use a repeater is it a mesh or AP solution? I find Android will drag its feet letting go of a wifi signal even when walking into range of another known network. Had an extender in garden and even when down to 10% connection on Wi-Fi it would stay connected to extender, I had to turn wifi off and on quickly to get it to pick a better network.

Definitely try what lywyn suggested...
you can also submit an error report on Samsung Members app, it sends reports directly to Samsung and get the feedback.
Download the app from the Galaxy Store if you don't have it on your phone > Memers app > + button > Error report

Unfortunately no success. I configured exactly like suggested. Does the S21 Ultra have problems with handover in meshed WiFi setups?

sometimes it happen when you connect at certain locations.
If you haven't already done so give this a try. Settings, search "Wi-Fi", scroll down to Location, Improve accuracy - toggle on, Wi-Fi scanning - toggle on.

Mesh is a single network solution so should not be a problem.
The only other thing I can think of is the power-saving mode. My son has his Pixel on power saving all the time and I know sometimes he has to turn off/on wifi to get a connection when waking the phone up
I found the issue! It is WiFi Direct related. The app "nexar" from the dashcam is interfering with normal WiFi on this phone. Nexar conquers the WiFi functionality and is responsible for my wifi disconnecting. The app requires the "Location always" permission. If I remove this permission my WiFi works again normally. So: one has a similar issue: remove "Location always" permission from the nexar app. In my case it helped.
You said the phone loses connection and and many others. Does that show up best on the region you described, or does it also happen at different places?
Kodi nox
It is feasible that your phone additionally receives harassed with the router and the repeater.
1st you need to honestly recognize if the issue comes from the cellphone or likely from your WIFI devices. Once this is clean, you've got something to go on with...

Question Data connection is active even when on WiFi

Hi all,
I'm noticing that the data connection seems to be active even when on WiFi. Is there any option that I need to disable so that the phone runs entirely on WiFi. I looked in the developer options and keep data alive option is unchecked. Am I missing something?

Hi, just go into Wi-Fi Settings / Advanced and switch off tab (Switch to mobile data)
That's all.
Hi. Thanks for this but this option was never enabled in the first place. Anyways, it's self corrected now...aah..the wonders of the tech world

It's enabled by default just to keep your internet connection stable when wi-fi has an issues.

It will re-appear occasionally. Even if you turn off the "Switch to Mobile Data" setting, the mobile data icons and wifi icons will appear concurrently on the status bar. This happens even when the wifi connection is solid. Usually the mobile data icon disappears after a few seconds or minutes on its own. I'm not sure if its by design (for MMS or RCS or something else) or if it's a bug. But you're not the only one seeing this. My colleague has an S21U too and he shared a similar experience.

I'm suffering from the opposite problem!
I *WANT* to keep mobile data enabled while connected to Wi-Fi, but the setting on my phone has no effect! When I turn on the setting, my phone will still ignore mobile data.
I verify this by connecting to my dashcam via Wi-Fi. The dashcam does not provide any internet via Wi-Fi, but merely allows my phone to view the dashcam output and stored files. But once I connect my phone to the dashcam, then my phone has no connection to the internet. I can't force it to use the mobile data at that point. The phone is not behaving as it should. My older phone, LG G6, is able to successfully connect to the dashcam and still access the data through the cell signal.
The S21 Ultra simply cannot achieve this. I have the T-mobile variant, in the US.
I believe this is a bug. Can you get this setting to actually work? Like maybe test it by connecting your phone to your Wi-Fi router but disconnect the modem from the Wi-Fi router?
I'll post a separate thread for this, because I think it's a bug and maybe others are suffering from it without realizing.

Question Bug - Wi-Fi advanced setting "Switch to mobile data" nonfunctional, any others have this?

Hi:
My S21 Ultra is the T-mobile variant, in the US.
The Wi-Fi advanced setting for "Switch to mobile data" is nonfunctional, because it has no effect when turned on.
I'm hoping that others can verify this problem: When you are connected to a non-functional Wi-Fi signal (e.g., your phone displays an exclamation point (!) next to the Wi-Fi signal strength indicator), your phone should still be able to access the internet by switching to mobile data, when you have this advanced setting turned on.
However, with my phone, I *CANNOT* access the internet when I connect to a non-functional Wi-Fi signal, whether I turn on or turn off the "Switch to mobile data" advanced Wi-Fi setting.
I'm hoping others can confirm the same issue, so we can escalate as a bug that Samsung can fix. Or maybe somehow it's an issue specific to the T-mobile USA variants of the S21 Ultra?
Anyway, I'm guessing most people don't encounter this bug, because usually you are on a functional Wi-Fi signal. But in my situation, I *NEED* to be able to connect to a non-functional Wi-Fi signal, and access data through the mobile/cellular tower connection. The reason is because that's the only way I can update the firmware on my dashcam. My phone connects to the dashcam via Wi-Fi. That works, and the app can view the dashcam etc. But the app also needs a data connection to download a firmware update for the dashcam. But when I'm connected to the dashcam via Wi-Fi, the dashcam does not provide internet. So I'm stuck because the S21 Ultra *WON'T* access the internet when connected to the dashcam via Wi-Fi, because the "Switch to mobile data" setting does not work and is ignored, so the phone has no data connection whenever I connect to my dashcam.
I figure, if T-mobile doesn't allow this, then they should remove the setting as an option. Why include the setting if it's simply ignored and nonfunctional?
There are some added wifi settings in the developer mode like, wifi scan throttling and wifi safe mode, have you looked into these? I don't have any wifi problems on my S21U unlocked phone, not branded.
In my developer options, Wi-Fi safe mode is off, and Wi-Fi scan throttling is on.
But the issue is my phone refuses to connect to cellular data, even though I tell the phone to please connect to cellular data when the Wi-Fi is unreliable.
I'm not sure that the Wi-Fi specific options in developer mode would cause the phone to refuse to connect to cellular data.
Are you able to connect to an unreliable Wi-Fi, and test whether your phone can automatically receive info via cellular data *WHILE* you are still connected to the unreliable Wi-Fi? You can simulate an unreliable Wi-Fi if you have a modem connected to your Wi-Fi router, and turn off the modem but leave the Wi-Fi router powered on with no internet.
Also, can you check your developer setting for "Mobile data always active"? Is that on or off for you? I don't want to turn on that setting, because I want the phone to save battery and turn off mobile data when I'm connected to a reliable Wi-Fi. The notable setting for me is in advanced Wi-Fi, where the phone can "Switch to mobile data *ONLY* when the Wi-Fi is unreliable and doesn't provide data.

Question Any luck with Intelligent Wi-Fi "switch to mobile data" when WiFi connection is slow or unstable?

Can anyone help me get this function working? Or is it a fake/useless/buggy function that serves no purpose but is included in the settings just for cosmetic reasons?
Under settings, connections, Wi-Fi, ..., Advanced, "Switch to mobile data" turned ON
But whenever I try to use my Wi-Fi to connect to my Wi-Fi dashcam, my phone reports there is no network and I'm unable to use the dashcam's options that require internet. I'm connected to a mobile network with full signal.
Is there something about my phone being confused on the Dashcam wifi?
My older LG G6 phone has no problem connecting to the Wi-Fi dashcam while using mobile network, but Sprint is about to shut off that phone's mobile network so I'll be out of luck when I need to rely exclusively on my retarded Samsung Galaxy S21 Ultra that is not able to get this Intelligent Wi-Fi to actually work.
is it bugged or am I doing it wrong on the Samsung?
To clarify, our phones have a setting that I believe has no effect. I cannot tell if my phone is broken or if the setting has no effect for *all* S21 Ultras.
The setting is called Intelligent Wi-Fi "switch to mobile data," when WiFi connection is slow or unstable.
You can find it under settings, connections, Wi-Fi, ..., Advanced, "Switch to mobile data" turned ON
When I turn on my setting for this feature, the feature has no effect because anytime I connect to a dead Wi-Fi signal, my phone reports there is no internet, despite having full bars 4G/5G cellular signal. The only way to access the internet is to turn off Wi-Fi in this situation. The setting should make it so you can still use the mobile/cellular network regardless of your Wi-Fi status.
Hey there, I think I have an idea what you mean. I'm sure you can setup a bixby routine to turn off wifi. Probably need another trigger to turn the wifi on such as a location based trigger

No, you misunderstood the problem.
Here is the problem: how can you maintain a network connection to the cellular network, while still connected to a Wi-Fi signal that is poor/spotty or otherwise has no internet?
The problem is I *NEED* to remain connected to a Wi-Fi signal that has no internet. The phone is too stupid to automatically use the cellular network, even though there is a setting that literally says the phone can do this.
When I turn on the setting the phone doesn't behave as though the setting is turned on.
You can simulate this connection arrangement, and I can explain how, if you are willing to try it?

I will try this today after work.
The Developer Options includes this setting: Mobile data always active
The developer option is not ideal because I don't want to leave mobile data active all the time, but hopefully it will work! The setting in normal options, for intelligent wi-fi, seems like it would intelligently conserve battery by not leaving mobile data active all the time, but only when your Wi-Fi is spotty/poor. Unlike that, the developer option seems to ignore the Wi-Fi quality and just keep mobile active always.

No setting or developer option works to allow the phone to have a network connection via cellular once you connect to Wi-Fi where the Wi-Fi is bad.
Can you elaborate on tasker? My understanding is there is no routine that could make the phone maintain network connectivity to cellular network once you connect to Wi-Fi, because the phone is incapable of performing this functionality that it's plainly supposed to be capable of.
There are two settings that are supposed to do this "dual" network connection: intelligent wi-fi or developer option keep mobile active always.
For my phone, *BOTH* settings are fake or not implemented. I wish someone else could confirm?
Just went out to the dashcam, connected my phone to the dashcam via Wi-Fi, and once connected to the dashcam, my phone was unable to reach the internet.
I verified all the following combinations fail:
* Intelligent Wi-Fi on, developer mobile data active off
* Intelligent Wi-Fi on, developer mobile data active on
* Intelligent Wi-Fi off, developer mobile data active off
* Intelligent Wi-Fi off, developer mobile data active on
My point is no combination of any setting can do what the phone is supposed to do. Therefore no tasker routine could somehow enable the phone to accomplish this.
Could anyone please try to verify this? I'm trying to figure out if it's just me, or if all phones suffer this bug failure to implement a feature mentioned at two different places in the phone (settings for advanced wi-fi intelligent Wi-Fi, or developer option for keep mobile data active all the time).
To verify, just unplug from the router the cable that goes from the modem to the router, so your router will still accept Wi-Fi connections from your phone, but your router will no longer have internet. At that point, see if there is any possible way for you to browse the internet via the cellular network.
My point is your phone will stupidly refuse to use the cellular network because it's connected to Wi-Fi, regardless of you telling the phone to use the cellular network via either of these settings (intelligent wi-fi or developer keep mobile data active).
Yeah I got your point. Maybe a bug in the firmware or with your phone, because I have experience with the S21 Ultra of bad wifi network connected and 4g coming up (then I don't see the wifi network icon in the bar up). And then the wifi settings was saying something like "will reconnect when connection is good". I don't know why it doesn't work for you.
Do you have the Wifi energy saving mode option on ? Mine is off. Auto switch to mobile data is on in wifi setting. Developer option for always on is off.

I can see your point when it comes to the setting "Intelligent Wi-Fi - Switch to mobile data": It sounds like your phone is "disconnecting" itself from the bad Wi-Fi signal, so your phone is *NOT* connected to any wi-fi when it works via a cellular network connection (4g coming up). Is that correct?
But I don't think the developer option for "mobile data always active" works that way. Instead, I think it should do what it says, and keep the mobile data available regardless of whether you connect to Wi-Fi, and regardless of Wi-Fi quality.
I'm trying to *maintain* the connection to the Wi-Fi network that has no internet, so that I can use the internet via the cell phone network without disconnecting from the Wi-Fi signal. Currently, my bad Wi-Fi network is listed as one of the "Network exceptions" under the "Switch to mobile data" so my phone knows not to disconnect from that Wi-Fi network when it sees the absence of internet via that Wi-Fi signal.
But I don't think the setting for keep mobile data active will cause the phone to disconnect from a bad Wi-Fi signal.
Are you able to try turning off the intelligent Wi-Fi, and turning on the keep mobile data active, to see if your phone still behaves that way (disconnecting from the Wi-Fi)?
Have you managed to solve this? I have the same problem..
settings - connections - data usage - mobile data only apps

Thought of that, however then I should enable it for all apps I am using during driving such as Spotify, Google Map, Waze, etc. and each time I have to reverse it. That is just too complicated and tedious and not a solution, neither a not viable workaround.
Hmm, looks like the settings, connections, Wi-Fi, ..., Advanced, "Switch to mobile data" no longer exists after the somewhat recent Android 13/One UI 5.1 OS update?
I'll have to try the new approach above for my dashcam, but the problem is my dashcam provider updated their dashcam app and it instantly crashes on my phone now running Android 13. So I will get around to this eventually, once my dashcam provider updates their dashcam app again so I can run it and test.
It remains to be seen, after eventually assigning the dashcam app to mobile data only, if that assignment will interfere with the dashcam app's ability to connect to the dashcam via Wi-Fi. The issue is that the dashcam app needs to connect to the physical dashcam via Wi-Fi which lacks internet, while also using the mobile data connection to get internet from the cell phone tower. So it's the same app that needs both forms of connection. The new settings seem to be either/or, but NOT both. I'll just have to test it eventually.
