[Oreo] No mobile data after WiFi - OnePlus 3 Questions & Answers

I'm having an annoying issue since upgrading to Oreo.
When disconnecting from some WiFi networks the mobile data doesn't turn back on. No amount of going in to airplane mode fixes it. A reboot is usually required.
It doesn't occur with all WiFi networks.
Has anyone seen this? Or know a fix?
I'm running Oxygen 5.0.1

No one seen this?

Hey, I lose mobile internet connections quite often.
Haven't noticed a trend, so can't say if it's Wifi related. Neither toggling aeroplane mode or mobile data on and off makes it work again so I just end up resetting the phone.
I'm sorry I can't offer anything useful, but I can at least say you're not alone!

This is happening to me as well oxygen 5.0.3 , total pain I've got tasker to switch on hotspot and mobile data when I enter car but Data doesnt connect and have to reboot phone

Data connection problem when coming back from Airplan mode...

I've stumbled on a strange issue.
If I switch the Desire to the Airplan mode when the Data connection is off (I use the appropriate HTC Data connection widget to do this), when I switch back to Airplan mode off, the phone is no more able to restore the data connection.
The only workaround found is to restart the phone.
Has anyone got the same experience?
Two questions.
1. When you say you switched off data connection, are you talking about syncing, wifi, mobile network, ... etc?
2. Why do you want to switch off data connection and turn on Airplane Mode? Doesn't Airplane Mode cater for shutting down all wireless?
1. I'm talking only about the "Data connection" option on "Wireless and networks" menu, that is switchable via a special HTC widget. Switching this option off, the phone is no more able to access to the GPRS provider. I often keep this option off to save battery life. I turn Data connection on, if I need to sync and access to Internet.
2. This is not the matter, just it happens. Eg. When I go to sleep, I turn the Airplane mode on, doesn't matter if the Data connection is on or off (it is possible that it is on) in order to avoid any disturbs (calls, sms, etc.).
I just wonder if this issue is a true bug of the phone:
1. Switch off Data connection
2. Switch on Airplane mode
3. Switch off Airlplane mode
4. Try to activate Data connection (for me it seems it's not possible without a reboot)
Had a similar problem which I wrote to HTC about: after the phone has been data connected via wifi and I leave the wifi network it often will not connect to data via mobile network (GPRS/3G), giving the message "connection failed" if I try to manually connect in the "mobile networks" section of the "wireless & networks" settings page.
It seems to have fixed itself now, and I think it's because I've since ticked the option to "enable always-on mobile data", which I had turned off to save battery. Give it a try.

Thanks yurikg, but on my phone the "enable always-on mobile data" option is checked, anche there is no mobile network connection problem coming back from a Wifi connection.
The problem I shown is probably caused coming back from Airplane mode.
The other possibility is Juicedefender which apparently is known to cause problems recovering a mobile data connection (recent update may have fixed this):

I've not juicedefender on my Desire...
I've in plan to do some other tests...
I have a problem with my Desire reconnecting to a mobile data connection too, but not when I come out of 'plane mode, its when I leave a Wifi covered area. It could be the same problem, triggered by anything that disables and then reactivates the data connection?
I have no solution yet, and I have contacted HTC support about it (still no reply). There is some discussion here:

I seem to be having this problem too when coming off WiFi connection, unfortunately restarting the phone has not righted the issue...
I'm also having this problem with the connections. Fine on the wifi at work and at home but not switching over to the mobile network. Apart from that the phone seems awesome! Soooooo much better and more fun than the HD2.
OK, my phone appears to have no network connection whatsoever in fact...
Have the same problem as well. Coming from Wifi and to mobile network only - I do not get any data coverage. This is for the Desire and I had the same problem with Legend.
I hope this will be worked out ASAP.
Well, my problems all sorted. Turns out I had to manually input the APN for internet, took me by surprise since no phone I've owned since 2006 has needed that...
Just had to put in the settings manually too. Seems there is an issue with some of them. Would put a link here but as i'm a newbie not allowed Just google vodafone apn settings for htc desire and hey presto
Same problem here, my Hero had it too. I found it did work when you switch to gsm only and back to 3g/gsm... Would love to hear good solutions.
Im also having the same problem.
If i try switching my connection from wifi to mobile data, my mobile data connection fails to work. A power cycle fixes the issue but if i try switching connections again, the problem returns.
Can I suggest to anyone still having problems getting their phone to switch to mobile data when leaving Wifi to view the following bug report on Google Code and to star it to help raise the priority with Google:

Lose Mobile Data Access

Hello, Is anyone else having issues where mobile data will just stop working?
IE its enabled, working, 4g icon(what a joke!) shows up. then time passes, no 4g icon, Mobile still enabled, no internet access.
to get it working again, I have to either
A) reboot the phone
B) turn off mobile data, turn on Airplane mode, then off airplane mode, and before the cell looks for networks, turn mobile data back on. Ive had this problem on and off for a while now, and my mom just got one and she's having the same issues (albeit not as often as mine) I rooted mine, but her's is stock.
any ideas what could be causing this?
TIA

[Q] Turn Wifi off --> mobile data doesn't turn on automatically *EDIT* fixed!

I've noticed this on several recent JB ROMs (but haven't tried on stock yet)
Phone starts up, mobile data works.
Use Wifi for a while, then turn it off. Mobile data does not come back on automatically.
Either have to toggle mobile data or toggle airplane mode to get mobile data back again.
Anyone else having this issue?
*EDIT* Problem solved. The issue was with Wifi Calling.
When wifi calling was enabled, turning off wifi would not let the phone automatically switch to mobile data.
Disabling wifi calling has fixed this problem. Hope this can help others

I found the answer to the problem, see OP

WiFi not connecting automatically after boot

Hello,
yesterday when testing and setting up the OP3 I noticed that, after booting up, the WiFi didn't connect automatically.
I always had to go into WiFi settings, click on my WiFi and select "Connect". From then on, it worked normally.
(Had to boot really often, so it was clear that it was not a "sometimes" incident.)
Does anyone else have this?
I've had problems connecting to WiFi it keeps coming up can't authenticate connection also had LTE issues so I had to enter the wap details myself and that's OK but on the WiFi I've put a ticket in with one plus and waiting for reply..

With OxygenOS 3.1.3, now I don't have the WiFi problem anymore...
I have the issue where i completely loose data, there is no LTE or H. Flipping airplane mode on and off seems to fix the issue?

Issues with Mobile Data

I have an Unlocked HTC 10 that I bought directly from HTC. Sometime, when I try to send a text and I'm on Wifi, whether I have a connection to my mobile data or not, the attempt is an automatic failure, even if I try to resend. If I turn off wifi, it won't enable my data connection, even if I turn it off then back on. It forces me to toggle airplane mode on then off If I want to send a text or browse the web. Also, to make things worse, the issue is completely random. I have no idea that it has happened until I try to send a text. TBH, I'm not even sure if wifi is part of the problem, like maybe it is disconnecting from Mobile Data regardless. If it matters, my carrier is T-Mobile.
Keep in mind, I have wifi calling disabled because it was more trouble than it was worth. But for some reason, the phone won't switch to data without my intervention. If I go out of range of the wifi, it will switch, but not all of the time.
Like right now, under my connection settings, Mobile Data says "Disconnected" even though it is turned on. When I just toggled Airplane Mode like I stated above, the connection was established immediately.
Why is the phone not connecting to the Mobile Network automatically? It seems like common sense when it comes to smart phones nowadays and is really annoying when I send a text, only to find out 30 minutes later, it didn't even try.
From other threads it seems to be an issue with the most recent update from HTC. Only fix right now is to flash a ROM that isn't running the latest update.
