After I recently installed Pocketping 1.6, I noticed that even after I enabled WiFi on my Fuze, the IP address of my phone was not given from my local network. It was still based off of my 3G connection.
Question is, is there a way to change settings so that if I enable WiFi it will use that over the 3G without having to disable my Data Connection?
TIA -- and if this is in another thread, please point me in the right direction
Hello,
I have done a bit of a search about this but havent found an answer.
At work we have a network with wifi which is behind an authenticated proxy which the admins wont allow cell connection to. I have tried with various proxy apps but no luck. I need the wifi network to sync with the email server, which does work, however while on wifi I cant use the internet or receive txts from WhatsApp etc.
Basically I am just wanting to know if there is a way or an app, to enable 3G for a specific application while on Wifi, or to somehow enable both on request.
The dataplan I have at work is very restrictive, only 100 txt a month and 512mb Data a month on 3G. I therefore rely on WhatsApp to stay under this limit, but dont want my email app to sync to the server and download large emails while on 3G, only while on Wifi. And I need WhatsApp to use 3G as it cant get out via Wifi.
If anyone has suggestions or knows of something to get around this, I would really apprecitate it.
I am on a Galaxy S2 with Root.
Thanks
try droidwall- android firewall
Same issue
I have the same issue, only opposite, I use my phone at work to connect to a machine specific wifi router and vnc into the controls to control the machine. While I am on this connection without internet my 4g turns off and I get no data. Is there a way to force the 4g on while i am on a wifi without internet access so i can still access my email, pandora, etc?
I tried droidwall, but all that does is block the specific app from accessing the wifi connection, it still wont use the 4g connection while there is a wifi network connected, whether there is internet or not.
Oh yes, I am on a rooted Skyrocket on SKY ICS RC7.4 Speed (Great ROM BTW).
I'm guessing by the lack of response, nobody knows of a way to do what we are wanting, but I want to try refreshing this the once just to see if maybe the person who has the solution just missed the first time.
I did reflash my rom to SKy ICS 4.2A-8 if that helps. Im willing to use different roms, mods, hacks, whatever it takes to make this work.
I usually use WiFi or 2G. I noticed some sites don't load fully or stalls forever. So I wanted to change the mtu just like I did in my PC.
With wifi it is easy. "1460" >> sys/class/net/wlan0/mtu and an startup script to change it every time! It worked great.
It is easy to figure out wlan0 is for WiFi, one of them in the "net" directory. The thing is I can't get figure what is the interface for 2G network.
So what is it or is there another way?
Am I asking it in the wrong section?
Hello,
I'm having trouble using my phone in roaming. My home mobile provider is Vip net., in Croatia. I'm currently in England, and my phone is currently connected to Vodafone network, which a partner of Vip.
I'm unable to get mobile data connection unless I'm connected to Vodafone 4G network. When I do a manual scan of networks, I can see (most of the time) three instances of each network (4G/WCDMA/GSM). Whenever my phone decides to switch from 4G to WCDMA or GSM, I lose the mobile connection.
APN is of course set correctly since otherwise I wouldn't be able to connect to the network on 4G (I've even had my provider send me the APN configuration message to make sure that's correct - I also tried various modifications to settings of the same).
I've talked with my providers technical support and they haven't been able to provide me with a solution, so I'm wondering if anyone here might have a clue about what is happening?
I've tried doing some basic diagnostic with adb, but haven't been able to gather much from modem logs, which I've attached here, and I would be grateful if anyone would take a look.
Here is the log, please note that it starts with me turning on mobile data and ends with me turning it off:

The phone in question is LG G5, Android 7.0 Nougat, Stock rom. (I had the same issue on 6.0)
Thanks guys!
Hello XDA Community!
When my new phone (Huawei P9 Lite Mini) is on 3G/2G auto network mode, it consumes more battery than LTE/3G/2G auto mode even mobile data off.
I do not understand how this happens? For example, while 3G consumption at overnight is %10-15; LTE is only %2-3. This problem is the same in daytime too. Mobile data is off, unneccesary services/apps disabled, and no extra application installed while this happens. I tried all "wipe/factory reset/update firmware/factory reset/wipe/no app install" procedures, enabling all battery saving options, but it did not work. This is a problem for me when I'm in non-LTE areas.
This problem occurs the same result in different locations. There was no problem with my previous phone and I use same nano sim card.
I tried the following but it did not work:
- Wipe cache, factory reset, wipe cache,
- Wipe data/factory reset over recovery menu,
- Update latest firmware, wipe data etc. again.
How this happens and where am I doing wrong? Thank you for your help, best regards!
EDIT: PROBLEM SOLVED!
I changed my mobile carrier (provider) and the problem is gone. This is very interesting! I worked for hours and days to solve the problem, but this problem is neither caused by the phone nor by the software...
WCDMA (aka 3G with support for 2G/Edge) is in always-on mode on most phones, because that's how you receive and emit phone calls and, for most phones, SMS (in some more recent phones, LTE takes care of sending and receiving SMS/MMS), so if you're in an area where 3G/2G reception is poor, your phone has trouble locking on a cell with enough power to maintain contact, hence the battery drain.
4G/LTE only works for data, and voice if you have VoLTE (Voice over LTE) enabled, but works on a on-demand mode, even with cellular data constantly enabled. In other words, the 4G modem on your phone will memorize the latest position and IP address the nearest 4G tower/cell allocated it, and connect to it using the memorized settings when you need it to.
Not so with 3G, where DHCP doesn't exist, at least not the way it does in 4G: it uses PPP (Point-to-Point Protocol), where an ad-hoc IP address is attributed to each new connection, based on a pool of existing addresses allocated to the tower and its owner (carrier) by the authorities.

Thank you for your reply!
When I googled about 3G vs. LTE battery consumption, everyone says that LTE will consume more batteries. That's make sense on first thought. So what I've been through is very interesting to me.
I think about is there a problem with my phone's 3G antenna. (footnote: I don't know about that 3g and LTE antennas are same or seperate?)
But I understand that you say this is normal, right?
Edit: I found a forum that this problem may be due to the operator (carrier). I'm still investigating...
3G and 4G operate on basically the same principle: receiving and sending "information" via radio waves.
The difference lies in the frequencies each standard uses, the way the data sent over them is modulated and demodulated, and how handsets make and maintain connection, so if you stay in the same location, and set your phone to 3G-only, then switch Airplane mode on then off, it'll take your phone longer to reconnect to the 3G cell/tower with the strongest signal (not necessarily the closest to you), because it'll have to go through the whole getting-acquainted process again, whereas in 4G, it'll go straight to the "Hey, how do you do? Long time, no see".
Now, if your phone antenna has a problem, you could be standing a few feet from the tower, in line of sight, and still get a crappy to non-existent signal. How many bars are showing on your screen is just an indication of how well your phone is receiving the signal from the tower; it doesn't mean that this signal is consistent and steady, hence the bars coming and going in real time.
If I were you, I'd download and install the Hidden Settings app from the Play Store, and run it; there, you go to RadioInfo, and you'll get a lot of information about how your phone modem actually works. It's a bit technical, but it would give you an indication.
I will try and looking for a new carrier. Thank you again. See you.
