Hey all,
I'm having a strange issue over the last couple of days and have also discovered that my brother, (he also has poco f2) is having the same issue.
Sometimes, usually when switching from wifi, we have no 4g, despite being connected to a 4g network.
It is an intermittent issue, so it is difficult to work what fixes it out why it happens in the first place.
So far I have tried, to no avail:
-Re-starting the phone, toggling aeroplane mode, toggling mobile data on and off, changing preferred network setting, changing apn, resetting wireless settings, etc.
Strangely, VoLTE seems to work fine. It only effects data.
We are on 12.04 global.
Any ideas?

My 3g seems to have stopped working. Wifi works fine, and 3g works for a few seconds during startup, then the icon disappears and there's no 3g. The icon always disappears just before the second media scan (does everyone's phone do two media scans during startup?)
I've tried uninstalling or disabling various apps, but every time, the 3g is disabled at startup. It initially stopped working while using Google Navigation. One second it was working, the next, no data, and it hasn't been back since, bar a few seconds during startup.
I'm in a major metro area with coverage, that's not the issue. I tried resetting the ATT WAP to default. That didn't help.
I'd really rather not do a factory reset of my phone.
Can anyone think of any options? Thank you in advance!
Have you tried toggling it into Airport mode and back out? FWIW a similar thing happens on my Nexus One and Milestone. I will have a data connection then it just goes away. The only way for me to get it back is a reboot, toggling data off then on, or toggle airplane mode. I haven't figured out the cause as it happens across multiple devices and multiple ROMs. It may be my SIM card.
Thanks, I tried that. No dice.
So I got it fixed. I'll post this in the hopes that it might help others.
On a whim I downloaded several apps that toggle 3g. Both APNDroid and Quicksettings showed that APN was on. Toggling them off and on didn't help.
But Smart Bar showed that APN was off. Clicking APN on immediately made the 3g icon appear, and it worked. Thank you Smart Bar!
Hey,
I have a Nexus 5 that is set up to basically act as a router using wireless tethering. I live in an area where I constantly have full-blast LTE that is usually above 30Mbps. For about a month, everything's been great until this last week. Now, every few hours my data connection gets killed completely after anywhere from a few minutes to a few hours after tethering has been running. Data stops working on all tethered devices as well as the Nexus 5. Entering airplane mode and then resetting the WiFi tether fixes the symptoms, and if that fails, restarting fixes it.
I've disabled wireless_tether_dun (sp?), switched to IPv4 and I sometimes use a VPN that passes through all network traffic through the VPN. Even with VPN disabled, the data drop keeps happening.
I know there are so many things that can be going on, but has anyone else noticed this recently? I'm wondering if it is a hardware issue, a signal issue, or perhaps T-Mobile has changed something on their side of things that is killing my somewhat obvious abuse of their network.

I am having the exact same issue -my post- in a completely different place, only I have been assured it is completely fine to use my phone on the network in this way. Did you ever find a solution to this?
Got a new S8+ yesterday.
Everything is fine except WIFI, it keeps disconnecting all the time, going on and off, until it finally stops working...
I tried removing all background signal checking and all unnecessary options, and also I did reset it to factory twice, but the problem persisted...
I have my former S7 Edge on the same network without problems...
I am having the same issue. Disconnect then reconnect every few min.
I had one disconnect this morning but it transfered to the 2G instead of the 5G.

Check your network settings; it may be switching between LTE and WiFi to "conserve energy, buy having the strongest connection." I have had that issue in the past with other devices.

Tried that already, but it is completely disabled..
In fact
Nearby Device Scanning is OFF
Wifi Calling is OFF
Location is PHONE ONLY
Smart Network Switch is OFF
Network Notification is OFF
Hotspot 2.0 is OFF
Keep WIFI on during sleep ALWAYS
and it is still happening.....
When I was first provisioning the device at home I was running it off a Ubiquiti AP Pro and kept getting disconnected. I took it off WiFi and ran the setup on 4G LTE only and connected to my WiFi after. I run Google Fiber and did some 5GHZ speedtest and was never less than 600mpbs up and down. Absolutely 0 chance the initial issue is my network at home. I haven't seen it disconnect since the initial setup but that does worry me a bit. I'd wipe the network profile and set back up.
Probably unrelated but I've found that the 5Ghz WIFI strength on my S8 5.8inch is terrible. The 2.4Ghz is fine though. Compared to my Pixel the 5Ghz is on average about 1/3 the connection speed at same range as the pixel and has much lower strength signal (testing with WIFIAnalyzer). If I cup the phone with 2 hands in landscape mode (how I normally watch videos) I often lose my WIFI connection completely from the 5Ghz network here.
Me to having same issue with WiFi disconnect automatically getting irritated from that
How to fix this guys
Had the same problem on mine. Setting the IP address to a Static IP fixed the issue.
Try going to settings, backup and reset, reset network settings. See if that works.

Hello there!
I'm been having a strange problem with my device, which causes a semi reboot.
I mean semi, because it appears to be rebooting, but it's faster and it seems to not complete the whole rebooting process.
I've been investigating and discovered that it's related to WIFI.
I have a Archer C9 with 2.4 and 5Ghz wifi. Each is set to a different SSID, so I know which band I'm using.
My S8+ is a FD Exynos at ZTO/CRC7 Oreo.
There's a option in advanced settings of wifi section, that automatically alternates from wifi to mobile, when wifi signal is weak.
So I found a spot in my bedroom where the S8+ loses wifi signal for a moment, but it's sufficient to make it alternate to LTE, either in 2.4 or 5Ghz bands (even though the 2.4 Ghz gets 40~50% signal in that spot).
After that, the cellphone keeps saying that wifi is weak and won't let me reconnect to it, even if I'm close to the router.
After a minute it reboots and connects to the wifi.
I disabled that option and so far (15h) it hasn't rebooted yet, even if I go to that spot (it loses wifi signal there, but recovers after a few seconds)
Is that a software issue or a hardware issue?
Thanks a lot in advance!
seems like a software issue since it works after reboot
try resetting the phone to factory defaults
Hi, recently I bought Ulefone Armor 8 Pro for my wife, and there is a strange problem with it. When she enables the GSM data, ther switch lights up, but there is not internet connection (also the arrows near the signal icon do not appear). She then has to go to connection settings, and change the preferred network from 4G to 3G. It then starts to work fine, but when she disables the data for the night, and enables it the next morning, there is no internet again. She then has to go to the settings again, and change the preference back to 4G, and it starts working until she turns the data off.
Turning the data off and on again after a short time does not cause any issues.
If the data starts working, the network preference can be changed around and everything keeps working. The issue appears only after disabling the data for a long time (I don't know how much).
I filed a problem report with Ulefone a week ago, but they didn't answer. Does anyone have an idea how to solve this?
I have also this model, and no problems.
Check if there are any ROM updates available.
