WiFi/4G problem

I have noticed that there have been a few times where WiFi is connected and 4G is connected also. The only remedy is to turn off and on WiFi. When this happens, sometimes I have no data connection (probably cause they are conflicting) but this can't be good for battery.

4G mobile network still connected when Wifi is ON?!
I have this exact same problem! Thing is, mine just started showing this behavior like a day or two ago. It's doing it right now. Both my Wifi and 4G icons appear in the notification bar. The 4G icon isn't showing activity (the download and upload arrows are dimmed), BUT if I go to my "Phone Info" app, and go to Phone Information it shows:
GSM service: In service
GPRS service: Connected
Network Type: HSDPA
Before whenever I was on Wifi only the Wifi icon would show up, and Phone Info would show GPRS Service as : Disconnected, i.e. normal behavior. Now it appears there is a conflict somewhere and the 4G network is showing as connected even when wifi is on.
Now, I did make some changes recently:
1) Temp-rooted and pm disabled a bunch of bloatware - this was like 4 or 5 days ago and I didn't have the problem at all so I'm not sure if it's related.
2) I unchecked Wireless Settings > Mobile Networks > "Enable always on mobile data" - Thought it might save battery when in sleep mode.
I think the problem started after #2. I've since checked that option back on, restarted, airplane mode, battery pull etc., but it's still exhibiting the same behavior. I've never seen this happen on any of my past Android devices (a lot). If I go to the Quick Settings it shoes Mobile Network is OFF but it IS checked. It's really confusing. When you turn Wifi on, Mobile network should disconnect, but according to phone Info, mine is on and I've been getting "network issue, try again" in the Market, and "Network Communication issues" in the Speedtest app so clearly something is being affected.
This has been my ONLY problem with my Sensation thus far, and the fact that it JUST started doing this makes me wonder what I could have done to affect it.
Thoughts?
EDIT: Every once in awhile the 4G icon WILL disappear leaving only Wifi on, and Phone info shows GPRS service: Disconnected, but eventually the 4G/2G icon comes back and Phone info shows GPRS service: Connected, so it keeps trying/turning itself on even though my Wifi is connected. WTF!

i dont have the problem of having both, i have the problem that my wifi seems to like turning itself off now and then. this has only started happening since temp root also

Thanks to Sdobron from the thread I had started, it looks like the My Account/My Device app may be the culprit. You can try killing the tasks/services and see if it helps. I personally just disabled both apps like I disabled all of the other bloatware, rebooted, and it seems to have fixed the problem so far (for the last hour anyway). Now I get only Wifi icon, not both Wifi and 4G, and the GPRS services is "Disconnected" as it should be when Wifi is on.

Hmmm did you disable any apps, and if so, which? Is your Wifi sleep policy set to "Never"?

If you're on a t mo device it's because of the my device app. Open and close it or end the process in system panel and it should fix the problem.

I believe this is somewhat normal...
I have voice only plan and disabled data through the *#*#INFO#*#* menus. The only way I can get data is through Wifi, which I always have enabled, regardless when I go to About Phone -> Network, I see mobile network type HSDPA.
It seems like voice is going through the 3G/4G but not any data. Not sure why you do get the 4G popping up, I sure don't.

Thanks! I tracked down the second package name for "My Account" (one is for My Account, one is for My device), disabled and rebooted. So far so good; Wifi is connected, no 4G icon, and Phone info shows GPRS service: Disconnected as it should. I had already disabled one package but not the other. I can live w/o the My account feature for a bit and I'll keep an eye out to see if the problem returns.

You phone will always connect to data whn using Tmobile apps such as my account app. Its because they need network data, not web data, to get their info like your usage, and billing. If you manually shut of data and turn wifi on and try to open the my account app, it will give you error.
Just because you turn Wifi on, it doesnt make the data shut off. It just connects to WIFI because its a stronger signal. It will still access the 4G data for netork required information. You can manually shut off mobile data and then turn on wifi if you want.

^This is true, I'm manually switching 4G off when connected to WiFi.

I realize this, however I was never trying to use the T-mobile apps.

Of course it does. What would be the point in having BOTH Wifi and 4g/3g/EDGE data on at the same time, all the time? That would be a HUGE drain on your battery if it were constantly using both radios and connected to/searching for both networks. When you turn Wifi on, the mobile data radio gets turned off. When you de-activate Wifi, mobile data turns back on. This is why you get much better battery life on Wifi because the 4g/3g radio gets turned off. Plus, both can't be connected at the same time or else there would be routing problems i.e., it would get confused as to which connection to use.
This is exactly what happened to my phone in that that both WERE on at the same time and it was causing no traffic to get in/out and I couldn't figure out why. Disabling the two t-mobile My Account packages solved it so it seems like
one was trying to connect in the background and couldn't but then froze the radio state. I'm not gonna re-enable the app to confirm but IIRC when you're on Wifi and fire up the My Account app, it either prompts you to turn off wifi, or it just disables wifi temporarily and fires up the mobile radio in the background, and re-enables when you're done.

Yep. If you keep the T-Mobile my account app running it will do that cause It needs the 4G/Data connection.

Right, but what I'm saying is that I wasn't running the app. It does run as a service though so I'm wondering if it was trying to connect on it's own in the background, though I'm not sure why. I haven't seen this behavior on any other devices including my Sensation before I disabled one of the My Account apps, but I'm almost positive at this point it was the culprit. Could be because I had only disabled one of them and not both. After I disabled the second, the problem went away.

Do you have WiFi sleep disabled?
If not, phone may revert to regular data until you start communicating and wake up your WiFi.
Just a thought.

Nope, sleep policy is set to "Never" and wifi sticks fine. Still happened even with screen on so wifi was def. awake. I fixed it by disabling the T-Mo My Account apps so I'm cool but maybe it can help someone else if they have the same problem. It's really weird, never seen it happen before. I wish I took a video of it before I disabled the apps. Thanks guys.

It's poor coding in the app. Nothing you're doing wrong.

New Motorola Defy, Major Connection Issues

Bought a brand new unlocked Moto Defy and I'm having some WiFi and data connection issues...
To start things off, I cannot get any kind of data on this phone. I'm able to make/receive calls and texts with no problem but when it comes to accessing data, it's a total fail. I've added APN's for ATT (ATT MMS, ATT PHONE, AT&T PTA), switched the 2G/3G/auto under Mobile Network Settings, and I just can't seem to get data working. I get data just fine on my At&t Samsung Focus with WP7.
Secondly, I cannot connect to my WiFi router. I've reset the router numerous times, disabled WPA security, tried different security methods, and it just doesn't want to connect. The network occasionally shows up with great signal strength but soon after disappears. I went to the same room as the router and it shows up. When I tap on it to connect, it shows "connecting" and then "disconnected". I also get a WiFi symbol in the upper left hand corner with a question mark over it.
And to top things off, I can't seem to format my WP7 memory card so I can't even install any apk's or ROMs. For some reason, the 2GB card that supposed to come with this phone wasn't even in the box!
Any ideas? Starting to get frustrated, this is my first android phone (3rd android device, first 2 were tablets) so I'm eager to mess with this thing.
Uploading a short video showing the WiFi problem.
Thank you so much!
Also, running 2.2.2

Anyone?

So I've installed Cyanogenmod 7 and was able to get to the band settings but when I select USA Band, it says "Set [USA Band] Unsuccessful.
I found a working bp_nvm_default folder for ATT, replaced original with that, set permissions, and nothing has changed.
I am at a loss of what to do now. And after installing CM7, I have no signal what so ever.
Please!!!! Any ideas?!?!?

[Q] Broken WiFi after OTA to ICS

Started with 2.3.6, OTA to ICS failed repeatedly, finally fxz'd to 2.3.5, then OTA to 2.3.6 then to ICS per jimbridgman's instructions. Everything worked perfectly except for the WiFi, which under "WI-FI NETWORKS" now constantly flashes between "Connecting..." and "Saved, secured with WPA2". But there is no connection and the signal shows very low (which it's not). If I forget the connection the network shows up very strong. This connection had been working flawlessly with both the phone and my laptop since April.
Under "Wi-Fi Settings" , if I hold down on the network and go to "Modify Network" and under "Show advanced options", the "IP settings" were set to DHCP which should have worked, but if I change it from DHCP to Static, an incorrect IP comes up (192.168.1.128, should be 192.168.0.128) AND the "Save" button goes dark! I can edit the address and gateway and all the other settings but it won't save them.
I have rebooted the phone and the wifi router several times and changed some of the settings on the router. I also tried turning off all 3 devices, started the router, then the phone, then the laptop, all to no avail. Reverted the settings on my router. Never had a connection problem on the laptop through all of this.
Rooted the phone also per jimbridgman’s instructions. Installed Titanium Backup. Uninstalled the ATT Smart wifi app (I KNOW, SHOULD HAVE FROZE IT INSTEAD) with no change. Reinstalled the app from the Play Store. No change. Froze Smart Actions from Titanium Backup, that did seem to change to flash pattern on the wifi network, and I can now set it to “AUTO” from DHCP, which I wasn’t able to do before, but otherwise there is no real change. I did reboot after each change.
I sure hope someone can help a NOOB with this… I need the wifi.
Thanks in advance,,

Wireless N protocol
After fiddling with this most of the day I looked at the connection attempts from the router interface: Apparently the Atrix 2 is NOT using wireless N anymore, and the rest of my network is.
Anyone know how to set the wireless protocol in the Atrix 2?

Connected in G mode
Changed the router to mixed mode and the A2 connected, checked the client list on the router and it connected in wireless G mode. Ugh. I'd really like to keep this thing in the N mode.
Any suggestions? Anyone else seeing this? There's gotta be a way to change it to N mode, especially since it was using that mode exclusively before ICS.
Thanks,

[Q]nexus 5 cant find wifi

Hey guys!
So I have a problem with my nexus 5.
Lately it seems as if it does not find "new" wifi connections... It connects to the one it already has saved.
If I click scan no wifi networks appear even though there are many(my pc and other phones get good signal)
I also get the notification saying "There are networks available" but when i touch it no networks appear...
Any ideas?
Cheers!
EDIT: I just tried adding the SSID and it connected fine and works great.... So the problem is the actual scanning...

You say that it happens "lately". So it worked previously? Anything change right before the problem arose? What is your phone's configuration, i.e., ROM, kernel, Xposed, runtime, etc. Have you rebooted the router? (I know, your other devices see all networks, but, what works for one may not for another)

I would suggest that the router you are connecting to is set to not broadcast the SId - simple (but not too effective) security measure.

Same problem here! I got my N5 yesterday and wifi was perfectly connecting to my router. The I unlocked the bootloader and root by using WugFresh's Nexus Root Toolkit and phone is not detecting anymore my wifi network. Phone wifi works since I see the others wifi around but not mine!:crying::crying:
I did the following but problem still present:
- powered off the router
- changed SSID on router setup
- removed security on router setup
- add manually the wifi into Nexus 5
I have no clue on what I can do more....pls help!
EDIT: solved: I noticed my router was set on specific channels for wifi, then I modified to AUTO

If i remember correctly, Nexus 5 version 4.4 had issues connecting to WIFI channel greater than 10.
I had this issue also.
