constantly looses internet connection only Aeroplan mode helps!!! - OnePlus 3T Questions & Answers

This is drives me nuts!!! Connection status showed as H+ and very often suddenly internet dissapears!!! And it's not going to work again before I switch all phone to Aeroplan mode and back!!!
Today I thow my phone at a wall Hoping to break it to have a reason to buy a new one without this problem.
Anyone else?

What mobile provider do you have, and does it happen in more than one location so it's not just an unstable transmitter in your neighborhood?

Yes it happens when Im at home, probably with not so strong signal. What seems to be the the bug is that signal status in systembar shows that all is well with connection. But internet is absent. I use two sim, and it happens at all combinations of slots
Probably a solution to this will be a script that periodically check some online url and switch Aeroplan mode on/off if internet is absent.

Meaning what exactly? Just having the H+ symbol, or showing a bar or 2, does not mean much. I often will get a bar or reception showing on this phone when in remote locations, where there is no usable data signal. My wife's iPhone is the same way, shows that there is a phone and data signal, but no actual internet connection. The signal is present enough for the phone to see it, but not strong enough for any data to get through.
Go to phone Settings>About phone>Status>SIM status>Signal strength; and see what the actual dBM signal strength reads. This is much more reliable than any of the signal status indicators.

Thank you. Buut problem is that Android don't recognize that internet is lost before I switch to Aeroplan mode and back. I can wait for internet forever but as soon as I switched it connects immediately....

Really hate this piece if **** of a device!!!!!!!!

Do you still get this running on LineageOS 16? Can't say I've experienced this, running LOS and with keep mobile connection enable while on wifi-setting enabled in advanced development options menu.
Unless it's specific to your operator/mobile network. Have you checked your APN settings? Try deleting them and re-create from scratch.

WIFI? 3G?

I'm in the UK, and using a Touch Diamond.....on Vodafone 3G. When I'm connected to WIFI, I obviously want to use that for data, rather than use up my precious data allowance.
When I'm connected to a WIFI connection, how do I know Opera/IE/Email are using WIFI - and not my 3G connection? There are times when I'm in my house, and I know it's using my phone data connection, as it's just so slow (very limited reception 3G in my house)....whereas the WIFI should be pretty fast.
i COULD be wrong here.... but the way i know is if the WIFI icon at the top shows connected. If you rphone cant find the WIFI, it'll always divert to a data connection. Play with your phone around the house, see where you get connectivity and how strong to your wifi.

Yes I know when I'm connected to WIFI and how strong it is....what I want to know is how I know whether my phone is using 3G/GPRS - when I am connected to WIFI and want it to use WIFI and not my phone network. There seems to be no indication to show you are actually 'using' the WIFI network over the phone network....
Settings > Communication Settings.
Turn data connection off, turn wifi on.
Do that before you use internet and your sorted.
On both my Diamond and Touch Pro, the Wi-Fi icon appears on the task bar when Wi-Fi is available. Same goes for 3G.
Also note that some programs call for a certain connection method automatically. For example, you will note that some programs initiate 3G instead of using your Wi-Fi connection. Hopefully, there is a configuration option for such apps.
Cheers.
i don't know if you notice it, but if you are connecting through E or H or G or 3G.. the reception bar instead of the antenna you will get the corresponding letter if you are currently connected to one of them
As long as your WiFi is on and none of those letters are showing up.. you will be fine

Wi-Fi issue

So I will turn on wifi on my phone but for some reason it still shows the 3G bar and I get not signal at my house so when i try to load up webpages its clearly trying to use my non existent data signal rather than the wifi to load thing. why is it doing this? it's supposed to override the data but its not.

I would troubleshoot your network. The signal bars for cellular do not go away when connected to WiFi, so I would not suspect that is a symptom.
well i am aware of my router being complete crap but im not saying the cellular bars im saying even though wifi is enabled it still trying to use data instead of wifi.

How are you measuring that?
Check your IP address and see if you can verify from that.
All I know is that I've had wireless issues since day one with my turbo, in fact so bad that I just never use anymore (yea sucks)
I am at my inlaws, using my laptop to work all day on the wifi and connection is great. on my Turbo - the wifi keeps stopping, hiccupping, etc. I have to keep turning on/off, etc. to get stuff to work. I just gave up.
There are other threads on the Motorola Forum with similar issues.
Wish we could figure out what magic settings are necessary to make wifi stable.

Wifi and Data status bar icon issue

Okay so I need some help. Out of the box when you have wifi on you'll see the wifi signal strength indicator and Data strength indicator but the "LTE" icon will be hidden until wifi disconnects and mobile data is connected. I was trying out the setting "Aggressive Wifi/Cell Handover" and while it sounds good in theory it doesn't provide any noticable difference in real world use.
Anyone since having that turned on the LTE icon remains visible in the status bar even when connected and using WiFi. It's not the end of the world by any means but I'd like it to not be there as it wouldn't be before I tried out that particular setting. I've turned off the setting and restarted my phone a handful of times but the pesky LTE icon persists to remain visible at all times....
Does anyone know how I could get rid of it? I've tried everything and I've grown desperate now.
Thanks all.

Turn off Cellular Data always active/On. That might be turned on in that same developer menu list.

Disconnecting WiFi

Hello,
I've used my Mi A2 around 2 weeks now and I'm really satisfied with the phone. However, I got some annoying issue about wifi. When the signal strength of wifi is not so strong (below -70 dbm), it tends to disconnect for around 10-20 sec and then reconnected again. This happened to me like 10 times since I got the phone. And wifi works perfectly without disconnections when the signal strength is strong enough.
Does anyone experience this issue? Or I got a defected device?
Thank you
Same here, sometimes it just disconnects ...

It is a normal stock android behavior, because android detects that signal of wi-fi is to low, and tries to switch automatically to GSM mobile data, or to another wi-fi if it is available in the area.
I don't have this happen but wifi signal is strong and also; gsm data is turned off.
That *may* help to turn that off possibly, as it obviously can't (now) switch to it?

Even if mobile network is off? Is there a way to change such behavior? I tried to find in the setting but what I just found is Aggressive WiFi to mobile handover, which was already turned off.

I think that it is called smart wifi, or wifi+ option in other types of android OS, and here it is just a automatic option in stock android i guess.
I don't mind it, because it will change my wifi router AP if it get stuck, and need an reboot, so it will automatically switch to another closest one that works.
You better think of some way to get a better signal then to turn off this function.
Try with aps like this on the link.

The thing is that wifi also disconnected when there's no other nearby networks to switch to. I did something to get better signal in my room but this still happened sometimes.

Question Wifi <-> Mobile switching?

I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.
So you have both WiFi and 4G enabled and they don't switch seamlessly?
Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.
Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...
Hi, i have this problem too but it's not always.
I have a wifi 6 router too.
I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.
I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.
Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
