I have had this phone since its release in April and everything worked fine until October.
My phone started to disconnect from my mobile networks internet connection. Upon closer inspection I noticed it happened the moment my phone switched from 3g to lte/4g.
After showing lte in my signal bar it disconnects and stays that way until I turn mobile data off/on again.
Using the "3g only" option fixes the disconnection problem.
I have been on the same ROM from August to October, changed/flashed nothing.
Tried hard reseting the phone, no change.
Tried flashing newer radios and custom roms, no change.
I am starting to think it's a hardware fault.
If somebody has any knowledge about this I would be grateful if he could share it with me

Hi,
I just started my vacation in Spain but I've run into a problem with my cell. Upon arrival I notice that the phone won't connect to mobile data. Both mobile data and roaming is turned on, and it gives me the message of loosing the data connection if I turn it off, but I don't get any connection. What's even more weird is that I can't connect to WiFi either. All other devices here manages to but not mine. When connecting to the router it reads Connecting... but it stops and the access point reads Saved, secured with WPA/WPA2. Now and then I also get the popup notifying me that there are available networks to add to my annoyance.
Does anyone know what the heck is going on? Back in Norway both mobile data and Wifi worked flawlessly. I'm running RB 4.0 on a Samsung s3 (i9300)
It happened 4 times on my Note 3 in the last 10 days. I'm home or at work under wifi. Go out and try to use mobile data and I get an error message that I have no connection. Yet my LTE signal shows 50% and above in signal strength. I tried to turn on airplane mode to turn it off to force my phone to latch onto the closest cell tower and it's still doesn't fix the issue. If it happens while I try to upload some files, I check my email or try to browse the web and it confirms that I have no working connection to the web. I end up rebooting my phone and it fixes the issue. It's as if the phone is still looking for my wifi connection and "forgets" to switch to cellular connection once I leave the building. I know there is a setting under wifi that says to auto switch between wifi and mobile network but it doesn't seem to make a difference.
As mentioned in the title, the phone can no longer find a mobile network to connect to. It says "Error while searching for network", when I try to manually select a network.
It all started with 3G and mobile data not working well together - the phone would rapidly disconnect itself from the current mobile network, and then reconnect after a few seconds. I "solved" that problem by disabling 3G.
Then, the phone started losing even the 2G signal, but I could get around that by manually searching for a network, and it worked like that for two days.
Now, the phone is refusing to connect to any mobile network, and I can not even search for one. Meanwhile, everything else, like WiFi, is still working.
I tried flashing factory images (4.4 and 4.3), as well as various radio images (none of them with LTE enabled), but nothing seems to work. Do you have any ideas?
I got same thing after upgrade to 4.4.1. Started over flashing from factory 4.2 and the phone upgraded automatically to 4.4, still no mobile data but wifi is fine. Everything is stock.
Hi,
I have a problem that my WiFi network disconnects and disappear from the list. Even if I search for network it will not show up.
It looks like a lot of the other WiFi networks around me is also missing when this is happening.
It will suddenly come back again and work as it should for several hours.
I have i locked to 2,4GHz, WiFi always on, scanning is on.
Had the same problem when I used Auto 2,4GHz/5GHz.
All other devices is working as they should. Have also reset the wireless router. (Netgear X4 R7500)
I have the same problem. When I turn the wifi off, and the back on again it discovers my router and connects.
Does anybody have a fix for this?
Same problem here. My 2,4ghz network sometimes just vanishes and shows up after a couple of minutes. And it just won't connect at all with my 5ghz network. My router is a D-link dir 868l. I'm on the latest firmware. My other devices all connect just fine, except for my 6p.
Updated to 6.0.1 and I have still problems. When I come back home, I need to turn off and on WiFi to reconnect. Wifi have not dropped since i updated to 6.0.1 yesterday.
Just curious
Who is your service provider? My girls 5x is connected to Sprint and she has no problems on my network. I have Tmobile on my 6p and it keeps dropping the wifi. Maybe its a Tmobile thing?
reset network config
I had the same problem and try to go to airplane mode on and off then even forget network and add back on. Work for a second and disconnected. So far this way work. Try this.
Got to Setting > Backup & reset > Network Settings reset
Hopefully this will work for you guys too.
Good luck! :good:
My brother has a Nexus 6p and the WiFi doesn't switch on at all after he updated to 6.0.1. I reflashed factory image of 6.0.1 again and it didn't work. I then flashed 6.0 but it still doesn't switch on. Any help?

Anyone have a solution to this problem? I still have this big active, and have been using mobile data since.
For the last week or two I have been unable to connect my phone to wifi networks.
At first the problem would be that I was getting disconnected from any wifi network I joined, now I can't connect at all.
The wifi networks page sometimes (not always) does not detect a strong network even if I am standing a few feet away and the phone has previously connected and other APs are connected and working like my pc
If I try to connect then I get the "Connecting" status followed by "Saved,secured"
I have searched the internet looking for a fix to this and tried wiping the cache partition, forgetting the network, airplane mode toggling on and off, apps that wipe the known network list and some others including lastly a factory reset on the phone but nothing seems to remedy the issue.
From the wifi router I have tried using an unencrypted (open) connection
Now I think I may also be having problems with the bluetooth connecting in the car but I haven't had a chance to really investigate that one yet and it may or may not be related to the last factory reset.
My phone is not rooted.
Build no. LRX21T.G870AUCU2B0F3
kernel3.4.0-4443965

Can anyone offer any assistance to my current issue ?

I have just confirmed that the Bluetooth in my car is not detecting my phone when it scans (the phone bt is switch on and the visible box being checked) so that's both radios with similar issues.

Im having same issue with wifi... sm-g900r4
I just stumbled on a clue, while using an app called 'wifi cleaner' there is a feature allowing you connect to wifi networks within the app. I type in the password, authenticating is shown on the screen followed by "incorrect password".
I know the password to be correct..
Mmm

I was wondering if you ever got this issue fixed?
I thought I had but the problem comes back in a different way.
Sometimes wifi connects but only connects at 5 mbps.
Now wifi will not turn on at all. ( radio button is greyed in settings)
I did find a thread on xda where some Motorola users were having the wifi off issue and it was due to a missing system file which could be replaced on a rooted device. However I don't have root on my s5 g870a and it's not likely I can get it.
