Hey guys, I'm totally confused what's wrong with my xoom mobile connection. The sim card and 3g work fine when I put the sim into my htc cell, however on the tablet it refuses to work despite the dynamic tray indication (3g changes to hsdpa or to edge, even the up- and download arrows appear), though the indicator color is gray like it doesnt work. I have no idea what's wrong, I tried all the mobile connection settings, still nothing seems to get better. The problem appeared several days after my xoom was updated to official 3.1 (not rooted btw).
It worked fine before and after the update. I rebooted the xoom like 10 times, still no effect, same for factory reseting the xoom twice. In addition, the device network info shows that IP address is unknown.
What can I do to fix the connection? I'd appreciate any help.
seriously guys, no ideas?
I have a similar issue with my Optus MZ601 where it starts H data and then suddenly drops out, ending with the modem seemingly rebooting... Not sure whether this is my coverage in Aus, or whether there are other issues. I tend to suspect "Fast Dormancy" is on and playing a part in all of this, however with out a dialer, there's no way I can do the *#9900# to get into the menu and turn it off to test my theory.
Same problem
I'm having the same issues, It started a few days ago. Updated to 3.1 about a month ago with no problems.
Now I can't connect with 3G. Wifi works fine. tried everything from soft resets to full recovery. My xoom recognizes the sim and shows data connectivity but still can't connect.
Is there a problem with the update?
wow finally I'm not the only one with such problem.
did you guys reinstalled the stock 3.0.1 image? cause that's what I'm intending to do now. the only thing that stops me so far is that I'm not completely sure whether it will void my warranty or not.
I just don't want to find myself with a crippled xoom which moto refuses to take back >_>
After a couple of days of using my Nexus 4 i've noticed a problem with the way it handles the transition between Wifi and 3G internet.
Usually it works just as expected, when I switch Wifi off (or just go out of wifi range) it automatically switches to 3G internet (coverage icon in blue). The problem is that sometimes, after switching wifi off, it doesn't turn on 3G data (coverage icon remains grey). The only way I can get 3G internet back is turning Airplane Mode on, and then off again. ¿Am I missing something here? I've seen other people having this problem with other phones, but no workaround yet

This happens with my gf's Galaxy S3 too...
I think this is just a network coverage issue. My old mytouch 4g slide had the same problem. Usually it switches quickly if I'm in an area with great reception. If I'm somewhere with weak reception, it takes a little longer.

Well, I don't think this is a network coverage problem because when this problem happens, it can stay for hours with no 3G internet, it just doesn't even try. But then I switch airplane mode on and then off again, and it achieves 3G data connectivity almost immediately. Also, with the same SIM card I didn't have this problem with an iPhone 3GS.
Well, i've been investigating a little bit, and I've just found it in the AOSP issues tracker as "Android Issue #2207"
I've also found some apps like "3G Connection Fix Free" that seems to try to fix it
I'll try them and report back my findings
I think I have this problem too sometimes. I think my phone has other issues, I'm about to send it back to Google because it keeps dropping cell signals as well, but I definitely have this same problem.
Yes, it happened to me as well yesterday.
After I had more than ten hours at home using wifi, it can't switch to 3G automatically when I left home. The only way I did is reboot the phone.
But if I just connected to wifi for few hours it is OK.
Before I use One X, I don't have this problem before, but the problem is I can't access to internet once I am using wifi for more than 36 hours about.
I think there is big problem for Android system related to wifi and 3G access.
I don't think it's a nexus issue at all. It is definitely something else. My phone hands over form wifi to H+ in a matter of seconds every-time.
I believe you might have a coverage issue.
I am having the same issue, and can confirm it is NOT related to coverage. A reboot of the phone will immediately fix the problem. Have also tried disabling the mobile network, then re-enabling it, with no success.

Well, nothing i've tried has worked so far. It looks like if it stays connected to Wifi for many hours (for example overnight), it just won't switch to mobile internet unitl I reboot or do the airplane mode trick. I also have wiped everything and reinstalled the stock rom, but the problem is still there. Has anybody fixed it?
Had this problem with my Nexus One, with my Transformer 300 and now with my Nexus 4.
I use German provider O2 and after doing some research, many people suffer this problem and have O2. I thought it was related to my SIM card and I ordered a new one without success. My wife has O2, too. She never had a problem, not with her HTC Desire, not with her Galaxy Nexus.
I worked around with free app WifiFixer Free, which connects to 3G every 60 minutes. This doesn't seem to work on Jelly Bean, though.
The problem is all but new and I am out of ideas. I now use an app that enters and leaves airplane mode upon leaving a Wi-Fi network. But it yet has to prove that it works...
Any news in here? have the same problem and don't know how to solve it. It's so annoying

I have this problem too. Completely stock nexus 4. It doesn't happen all the time but when it does its very annoying.

On my Galaxy Note 3, when at home I am connected to my WIFI. When I leave the house or switch off my WIFI the phone seems unable to connect to the network (in this case Three) and the browser, email and any other data apps state they cannot connect to the Internet.
The only way to resolve it is to switch on Flight Mode and then turn it off again. I saw a comment in the reviews for the Note 3's keyboard fix that one other person is experiencing the same as me.
Is anyone else having this problem and do you know of a permanent fix? The only info I can find is a similar issue on the Note 2 at time of launch which look to have been corrected by a patch.
i have this problem so i flashed h3g uk firmware and it kept failing, so i flashed back to uk btu firmware and im stuck with the exact same problem. no idea how to fix either,
p.s my problem only seems to be with google now, play store and sometimes on any app that uses internet i get news feed error no connection ect..
I am on Three network and mine works OK.

Solution
I think I have found a work around to this annoying problem. It was losing the ability to use any data when I left a WIFI spot I was connected to, or when out and about and the phone picked up an open WIFI spot. None of the WIFI advanced options made any difference. It would affect 3G data too, I'd lose all data access until I toggled Flight mode off & on...that was the only way I could get it working again other than restart the phone.
I found a post about a similar issue with the Note 2 when it was first released and it mentioned a WIFI power saving mode. It turns out you can get to this from the SeviceMode screen by dialing this number *#0011# (ServiceMode will start as soon as you enter the second #) - assume it is the same for all. Once in ServiceMode, tap the menu button and chose WIFI. You will then see a WIFI Power Save Mode label with a button underneath. Tap the button to set it to OFF.
I've been testing this all day, normally I'd lose data at least three times, sometimes more, while travelling but so far today everything has worked flawlessly ... no loss of data connectivity. From what I have been reading, switching off power save mode does not affect battery life despite what you might think and I've not noticed any unusual battery drain today so far. So if you are experiencing the same annoying loss of data, try this before you take your phone back. Hopefully this is a software issue that will be fixed in the future.
I swapped the phone
Hi,
I had something similar, except it wasnt wifi related, it happened after I lost the signal for a while (eg, in a lift/elevator).
I tried a new simcard, and that didnt help (also Three UK).
Then I got the handset swapped for a new one at carphonewarehouse, and it fixed the issue, so I put it down to a lemon unit.
cheers

on my s4 and n3 i did more than 10 tests each on wifi and 3g with phones simultaeneously, both on same network, both held in my either hands, both using speedtest both connecting to same server, both on the three network sims on the one plan with unlimited internet including tethering (both pans in my name), same location, same times tests were done.
both on 3g and wifi the n3 is MUCH MUCH slower than the s4 both on three network and same wifi
********************* on wifi on 3G
S4 PING TIME 32 to 173 66 to 86
N3 Ping Time 30 - 37 73 to 1110
S4 upload speeds 8 to 17.79mbps 1.65 to 2.27
N3 upload speeds 7.11 to 12.58 1.74 to 3.77
s4 download speeds 17.79 to 22.38 6.61 tp 7.68
N3 download speeds 7.93 to 12.58 mbps 0.92 to 8.04
the numbers are not just it, even during speed tests i was losing wifi connection on the N3 a couple of times and see the same happening on streaming youtube where it keeps stalling on wifi unlike the s4. surely there is something wrong with the hardware of firmware
Looks like the WIFI setting only helped and it has not solved my problem. l now lose network data connection less often when leaving a wifi zone but it still happens. More worryingly on two occasions now I have lost all access to three including calls, texts and data. Toggling Airplane mode brings everything back to life but this makes the service unreliable.
Sometime I also have this problem. This is similar to when I went overseas, I turned off the data roaming, but it always unable to connect to data when I returned. Usually I have to reboot it.

Just got this alert as it was in my spam box hence the late reply.
Had done this comparison video of the note 3 versus nexus 5 WiFi speeds on same router and nexus 5 was giving speeds of up to 50 Mbps and the Samsung galaxy note 3 was giving 0.5mbps plus drop outs! See video https://www.youtube.com/watch?v=w-XvFPwTAGA
The router works fine with my 3 nexus 7 tablets, 3 Tegra note 7 tablets, Samsung galaxy note (original), 2x android mini PC, 2x smart TV's from Sony and LG, 2x smart bluray players from Sony and LG, laptop, smart camera from Samsung, Panasonic stranger, my NAS drives, 2x old HTC desire phones, a few other old phones from Sony and Nokia and media player from samsung and archos, the only device that ever had a problem with any Router is this Samsung galaxy note 3.
Main problem happens when there are open WiFi networks around our you have selected the auto detect in settings. Here is the solution https://www.youtube.com/watch?v=MjL8JbSQCvw and now I get 50mbps with same phone and router! So it was **** Samsung software to blame!
Now I have triple sim adapter in phone and all three give me 3g signal in Many areas.

I have a Note 3 and this always happens to me when I return from travel overseas. I turn off mobile data and data roaming and use Wifi, but am never able to reconnect when I return. The first time I fixed this by rebooting. This time I tried restarting my phone, removing the battery, turning off Wifi Power Saving Mode by dialing *#0011#. Fortunately I was able to fix the problem simply by toggling Airplane mode without having to reboot. Hope this helps.

About a month ago I noticed that my wi-fi is working weird. It is connected, but I can't use the Internet. Looking at the wi-fi icon I can see that it is sending data to my router, but it is not recieving anything back. I basically have the arrow going up, indicating upload, but no arrow down, indicating download. After a few minutes (or after restarting wi-fi) it goes to normal for some time and then it stops working again. I'm currently on optimised CM12.1, but it doesn't matter which ROM I use. My router works fine. I checked with another phone while my s4's wi-fi wasn't working. I was considering updating baseband and modem, but I wasn't sure which one to use. I'm in Poland and my carrier is Mobile Viking, but they use Play infrastructure (or T-Mobile, if play is unavailable). It isn't anything that would make me change my phone, but it is a bit annoing.

It's like you said. The only thing you can try is changing your modem.
Do you have a stable connection on other wifi networks?
I have no way of checking other networks (living in a small town with no public wi-fi). Which modem should I use? I'm in Poland nad I bought my S4 in a store (not from any carrier)

There is no best modem. You have to try it for yourself. I would suggest taking lollipop modems, but you have to be on a lollipop bootloader for that.
If I am on lollipop rom, does that mean that I have lollipop bootlader? When I bought my phone it was on android 4.4.2
Since lollipop my wifi has been terrible on my i9505 stock rooted. My iOS and windows devices are rock solid but sgs4 has crap connection strength. On previous devices the radio with the upgrade was normally to blame but I'd welcome any suggestions. Does cm12 use the same radio as stock?
Just as the title states, I'm having major issues with wifi. It's the phone, it's not the network or router because it works well with all of my other devices. I've tried resetting the router anyway, I've removed the network information in the phone and reentered it. The only thing I think that might have affected it without me knowing at the time was when I left the phone in my car and it overheated. I actually did that twice. If that is what caused the issue then I think I'm out of luck and it's likely not repairable. My first thought was the wifi antenna or something but because it does still connect I don't think that's it. Anyone else have this happen?
How you check your WiFi preferences?
By default WiFi disconnects after certain time...
Make sure is set to "NEVER"
Does it say "Connected, no Internet" and then disconnects and tries to connect again?
Is it switching to 4G because better signal? Turn off aggressive wifi handover in developer options if set. Check other settings too.
Turn off mobile data and see if behaviour is different as a quick test.

I can not find this setting, what menu is it under? I checked in Wi-Fi settings and Wi-Fi>Advanced. I've had the phone for some time now, this happened all of a sudden.

In the notification bar it would still show Wi-Fi signal status (on, with full bars) but it would go from displaying "network name" to simply displaying "Wi-Fi". If I long press it takes me to Wi-Fi setting and I can reconnect manually. If I turn wifi off and back on then it DOES NOT auto connect back to the network, despite the fact that the network is saved.

It happens when I have full Wi-Fi signal. Auto switching is apparently turned off, as mentioned above. When I turn off mobile data, it still disconnects from the network, leaving me with no data connection at all. Developer options were off, but I turned it on and checked but that option is off.

What Android are you using?
You could update to 7 / 8.0.0 US Beta or use a custom like me. Im currently on Android 9 Treble Pixel Experience and its working nice.

I'm running 7.1.1, B35. It would be nice if it was just a software issue, although I hate having to back everything up and wipe it. I haven't been keeping up with development, how reliable are A2017U flashes now? I think I remember them being risky with this phone when I first got it. Is any functionality lost? I would prefer to wait for the OTA 8.0 update since it seems to be coming but maybe...
I'm having this problem but mine says that the wifi manager has disabled wifi permanently. I can start it manually and it will connect to the internet for a few minutes then revert back to disabled. This happened after the 7.1.1 update.

ZTE Germany just released a message on their Facebook saying they're in their last stages of testing the Android 8.0 Oreo beta and will release it officially soon. This can be as long as one to three months away, or even longer.
If you're running stock, then flashing a custom rom will provide you with more functionality and performance. Battery life will definitely be shorter though, so say if you're getting 6-7 hours of Screen-on-Time on stock 7.1, you'll get around 4-5 on a custom rom. This entirely depends on your usage however. Flashing custom roms is quite easy and risk-free if you know what you're doing, and follow a good guide. Check Oki's guide on how to flash an 8.1 treble rom if you'd like. The current LineageOS 15 and 16 builds drain quite a lot of battery compared to other roms. If you'd like a good and stable Android 8.1 Rom, I'd recommend NFound's AEX 5.8. If you're like some of us (me included), you can live life on the cutting-edge and flash a Android 9 Pie rom. I wouldn't recommend it though as unless you know what you're doing with a GSI, DON'T flash one.
Always backup before attempting anything.
