Connectivity issues on Data (LTE/4G)? - T-Mobile Samsung Galaxy Note 3

Hello all,
I just began experiencing something weird on my phone today. It has been working fine for a month, no real issues. I was using it this morning and data worked fine. I picked it up this afternoon and tried to do a search in chrome, no connection. I have 1-2 signal bars (which is normal in my area) and I am connected to LTE/4g, but there is no connection to the net, almost like a firewall or something is blocking the connection. If I switch to wifi I am able to connect to the internet fine. Could this be some kind of weird outage on the tower in my area, or did something else break in the rom?

T-Mobile is doing a lot of Tower work. We had poor connectivity from the time I got the phone until last Thursday and then all of a sudden it started working a lot better. Even in the innermost room of the house which normally has poor connections.

[Q] FB17 Problems with searching for signal and wifi.

I'm Having a problem with my signal strength every where I go and WIFI as well. signal only peaks when I'm near towers and starts dropping as I get further away and I can't maintain data connection for nothing in the world.WIFI I run WIFI at home because im always on my phone. The moment I leave my house and come back it doesn't pick up the signal anymore I have to reset my phone so it can work. Is anybody having these problems and what is it caused by. Thanks in advance.

the problem of the reach of 3G,WCDMA,GSM ok

For me, a similar problem
Setting the network mode to auto or just wdcma makes the phone unusable.
Although the extent of the phone grabs. Nay, sometimes even 5 bars but the state does not tra large than 5 (sometimes 10) minutes and reach lost. Often with good coverage, I can not make calls and the internet does not work. Redials the phone ends in the subscriber information out of reach (the phone shows that he has range)
Switching the phone on GSM ONLY mode causes that everything starts to work as it should (only the net so slow)
The problem started a week ago
The problem occurs in various parts of the city, regardless of whether I use the transmitter Play network or roaming.
Factory reset did not help. I suspect the SIM card but the more I'm bending your point defect (eg antenna) since the last few months everything worked
EDIT:
1h watched by telephone yesterday, and what I noticed.
The problem is when a weak signal mode UMTS.
The signal strength of -90,-95dBm causes the phone to have problems. If the signal is below-100dBm the phone is able to maintain a dial-up connection to the Internet are no longer problems. Often there are also decreases above 100dBm signal which usually end up losing the connection of both GSM as well as internet and phone needs a few dozen seconds to reconnect.
If you set the mode to GSM only signal strength is-55dBm and the problems do not occur.

it's your network providers problem not our's. you can obviously not get 3G all around your city

[Q] Connectivity issue on stock SGIII

First of all, I did a search and found a few related things, but not this. So....here we go:
Stock phone. 4.1.1 and LJ7. Just started yesterday. Makes no difference if it's on wi-fi, or the regular "radio", I'm having an intermittent connectivity issue. Started when I was connected to our business wireless router. I was connected to the router...saw the IP address...but nothing beyond that. So I figured our internet connection was down. Nope.
Shut off wi-fi on the phone and forced wireless network. Solid signal with 3g....semi-solid on 4g...and no internet, no email, no nothing.
Did a few restarts...clearing cache...all browser details....no help. Did a battery pull. Nothing. Eventually, it all came up again, out of the blue.
BTW...I tried things like Facebook to see if it was just a browser problem and there was no connectivity there either.
Anyway, all was well until this morning when the same thing happened. This time at my house. I have Comcast internet so it being down wouldn't be a surprise. Reset the modem. Reset the router. Restarted the phone. Again, connected to the router...but nothing past that. Killed wi-fi again and the wireless networks were solid signal and no connectivity.
Got to the office and did a battery pull with everything else cleared again. Not working. Finally...for no reason at all...it was up again.
I'll take it to my local Sprint repair store, but has anyone else experienced this?
Thanks all.

Pixel 3 and Pixel 3 XL Wifi causing dropped calls and dropped mobile data

Both my wife and I have pixel 3's, I have the XL and she has the regular. Both were preordered and delivered at the same time, and we are both on AT&T. Since the beginning we have experienced random issues such as the phone dropping mobile data completely even though the signal shows LTE , and having to cycle airplane mode off and then on again to get data back. The other issue is that we both experienced call issues where our end would drop and we could not hear the other party, but they could hear us fine.
I think I may have traced these issues to WiFi causing the problems. When the data drops, I notice that my wifi is on and occurs when I am not connected to wifi (such as an unidentified network) and on LTE, or when I leave a connected WiFi area (like my house) and keep wifi on. We would have to cycle airplane mode to fix this.
For the calls, I had a call drop yesterday and when I looked at the notification bar it showed connected to wifi. I immediately turned off wifi and the call came right back. I thought this was an AT&T wifi calling issue, so I turned off wifi calling. Today, I was at the post office and had to make a call. Soon after connecting, the call dropped. I checked wifi and it showed unidentified network (not connected), so I turned off wifi. The call immediately came back.
So now, wifi is completely useless to my wife and I. Assuming I don't experience any more dropped data or calls, I cant use wifi to ensure good call quality and constant data.
Anyone else experience this? Could this be an RMA issue? Seems weird that it is happening to both phones. Is there a setting we should turn off that could be causing this?
i have a similar problem where if i am on wifi, when i get off wifi my lte or h+ will show bars but have a small x in the bars. i have to cycle airplane mode to get data back after i switch wifi off. i may just make a tasker task to do this.
i had a call from an s9 yesterday where i could hear them but they couldnt hear me. i think i was on wifi. we tried 2-3 times but he couldnt hear me. when i switched to my google voice phone number and called him, he was able to hear me fine.
there is another thread around here about similar issues. i might try to get a new sim card since this one is almost 9 years old.

I may have started that original thread a while ago, but since it was more focused on the data drop thing I created a new thread to help narrow the conversation towards the wifi issue. I went to ATT when I first had the data drop issue and got a brand new sim so it is definitely not that.

Question Connection Issues

I recently bought a Samsung S22 and for the last couple of days now I have started to see issues with the network connection (Not Wifi). I will see 3 or 4 bars that show signal strength with 4 or 5G, but when I go to open an app like TikTok, Facebook, or even Google Chrome the app just keeps loading like it isnt connected to the network. It seems like if I wait it out things start to work again after some time. At first I thought it may be an issue with the phone trying omegle xender to switch from 5G to 4G but now I'm not so sure. I wanted to check to see if anyone else is having this issue?
Same issue here, on Mint Mobile (T-Mobile MVNO). It usually happens while I'm driving or in certain buildings. Toggling airplane mode off and back on usually resolves it for me.
