[Q] GALAXY NEXUS network connection type confusion

Does anyone know how to fix this issue? My phone seems to get confused about if it should be connected through wifi or 3g/4g for data. For example, if I am at home and connected to my wifi, then get in the car and leave without disabling wifi, the phone acts as if it does not recognize the 3g/4g connection at all. It will just tell me I have no network connection since I am out of range of wifi. Same happens when I am connected with 3g/4g and I walk/drive by a wifi area and I do not join the network. The open app that is using data will then loose its connection and tell me there is no network connection. Simply disabling my wifi and restarting the app does not work. I often have to reboot the phone or turn off my mobile data signal and then enable it to establish a connection.

Any help would be greatly appreciated.

I have this problem also, I will have something like streaming music playing then when I am out of range of wifi it dose not go to 3g on verizon. If I don't have any thing using wifi and disable it before going out of range and starting a stream no problem, but when it happens I switch to airplane mode then back and it works fine.
Your not the only one who has this problem.

Same here. Not sure what's causing it. I have to go into airplane mode, which itself seems to take ages, and then turn off airplane mode to establish 3g connection.
I thought it may be a mess up from aokp, and after a clean wipe and flash it seemed fine, but then started showing the same behavior , failing to comnect to 3g after exiting wifi zone.
Does anyone have an answer for this problem? Is it a hardware glitch or software or app caused problem?
Any help would be dearly appreciated too!

Thanks for the info. Glad to hear it doesn't seem like a hardware problem, though I have yo admit I didn't see it on the aokp wikis ... Would you know if it's a problem for an unknown minority our a more general one?
So, I guess, then stock room should be fine? I was only on stock for a few days before flashing aokp. Going back would be a nuisance, but if I can have armless transition from wifi to 3g, then I guest I should -( ...
Any talk on when it may be solved in the aosp community?

Radios Dropping

Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...

If you are on a custom rom try going back to stock and see if it's the same. If stock try to update profile

I've tried that and it's still dropping... Would PRL/Profile also effect my Wifi connection? All data connections drop.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer has been turned off AND frozen using TiB from day one. So that's obviously not it.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.

Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.

Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!

hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing

Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

This ^, I have been having lots of problems with the Note 2 and connectivity. Especially with my airvana. Changing from LTE/CDMA to CDMA fixed all my problems including the random drop/reconnects with WiFi.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

[Q] H+ lock instead of 3G?

Hi, I am currently using Wind Mobile, and my area has very good signal. However I notice that the network icon is almost always 3G.
AFAIK, H+ is faster than 3G isnt it? Why am i getting 3G instead of H+?? Before I switch to galaxy nexus I always get H icon on my old G2X, but now i always get 3G! D:
Is there a way to lock it to H+ mode instead of having it swinging automatically?

From what I've read, you need to use your phone before it switches. It reverts back to 3g to save battery, I believe.
That's what I've read.

yeah I know, I want to lock it in H+ though, battery is not a problem for me as I am never away from a charger for more than 10 hours, plus I am a light user, I just want faster speed when I browse youtube or stream music thats all. Battery isnt really a concern to me.

It will change to HSPA+ when the phone is sending or receiving data. So in reality HSPA+ is enabled all the time. If the icon is your only concern you can flash a framework change script or try disabling fast dormancy if your carrier allows it.

Very poor Wi-Fi strength

I'm experiencing very poor Wi-Fi speeds lately. It's not the router because my laptop is fine.
Also, when I try downloading an app from the play store, use Facebook or the browser, the Wi-Fi disconnects. I quit the app and it's back. The apps that need Wi-Fi in the background (like whatsapp,fb) work fine.
Is anyone else experiencing this? Or do you have a solution?
Setup: aokp + Franco
Thanks

I don't get slow speeds as mentioned I get poor reception , my router can reach across the street with a computer but with my phone , it gets 1bar upstairs like wtf?
Sent from my Galaxy Nexus using xda premium

That happens to me too.
But when I'm near the router and I have full bars, the Wi-Fi disconnects as soon as I go to an app that uses internet. It is the weirdest thing.

Anyone else tether for gaming?

Now that LTE has been accessible in my neighborhood Id like to try and play BF3 while on my tethered network.
However, Tmobile only allotted me 500 mb per month complementary. I still tether, but only with user agent switched.
Now when I go to play BF3, in battle log it says my computer must be windows vista or above. So its reading the user agent and not letting me play =[
any ideas?

Yeah, stop tethering your phone to play BF3. Buy home internet service.

I have to get internet through a satellite. Super slow speeds but I get Tmobile LTE and I get about 40megs down
Sent from my SGH-M919 using xda premium

Wow. I get 50mb down 10 up and TV for 50 on xfinity. I did use tether when the internet went down for around an hour because there was a really bad thunder storm and it messed with their signal. It was pretty good. My Nat was moderate though. And I only tried it on BO 2

I've had LTE in my area now for a month or so I would say. Used it the other day to tether my PS3 while I played Black Ops 2. Connection was great, NAT was open I believe, and my connection in the game was always green with 4 bars and zero lag. I eventually hit the free 500MB tethering limit with T-Mobile and upgraded to the 4GB option. It's good to have in a backup situation when the power goes out or I lose home internet.

If you're rooted you can try Wifi Tether:
https://code.google.com/p/android-wifi-tether/
I play BF3. The problem will be latency, not bandwidth. From what I've read using wifi tether no on has had a problem yet. Not sure how you're lag will be like. Try it out and let us know if it's playable.

Sorry for the late reply, i dont use wifo tether. Tried that and got some very strange cut outs when doing speed tests.
Usb tethering gives me constant speeds. I spent a good month toying with wifi tethering using different adapters and they all had the same results (even an expensive 5ghz 500mbps wireless ncard would give me inconsistent signal.)
I am rooted but didnt have the tethering mod installed until my 500 mb free ran out. Hoping that when it comes back next month i can try to play bf3 again.
