Wifi connectivity issues

Has anyone else been having issues with their wifi connectivity? When I go into a different room in my house, my phone fluctuates from 3 bars to 0 bars, and sometimes loses wifi connectivity. Anyone know of a way to fix this? Thanks.

I wanted to post an update on this. I have tried changing the channel on my router to reduce interference, and I increased its transmit power. Since my laptop gets a fine signal, I wonder if the WiFi on this phone is just wimpy.

I have a different issue on both my and my wife's phones. After sleeping the phone with wifi set to "never" sleep, when I wake it there is no connectivity. It still shows as connected but I have to disable/re-enable wifi to get connectivity back.
I have never had this happen with any other device.

There is an option under wifi settings to use Max Performance. Try that.
Go to your WiFi settings and hit the menu button and select advanced.

Ok ill try that out and see if that fixes it. Thanks.

Still having issues. I hope there is a fix in the next update.

Forcing Infuse to use edge network.

Hope this hasn't been asked yet but is there any widget or system setting to force the phone to use 2g? I'd like to keep my connection at work but avoid the drain of maintaining HSPA in a brick building.
Thanks.

Yup...turn it off or use WIFI

You're saying that the only options are on and off?

HSPA is just like running 3g. But if you call *#*#6767*#*# then after that reboot your phone you should be good

Search market for "curvefish", grab their 2g/3g - on/off widget and download it.....add it as a widget to your home screen and you can easily toggle between 2g/3g...

Power Options is also a good one. I have it and it acts as a double for the power control widget that comes stock with android. you can customize it as you like.

I use power widget so I can use the 2g/3g toggle and stay awake toggle and always on as well.

So has anyone actually tried these on their Infuse. The widgets just take you to the Network settings where AT&T has disabled the ability to turn off 3G. Any way to turn on this option with a rooted Infuse?

I didn't bother to reply but I have the same questions you do. The toggle is not 2G/3G but data on or off.

curvefish has a widget toggle for 2g/3g on/off and data on/off

@SSJ_Gomike,
Your signature shows you sent this reply from your Infuse. Have you tried that curvefish toggle? I have it installed and all it does it take you to the network settings where the 2g-3g setting has been disabled by AT&T. I have the setting on my Nexus One, so I know exactly where and what to look for. So far none of the suggestions work.
My battery life is suffering since the 3g signal is week at my office and it switches back and forth between Edge and 3G/faux G.

There are several posts for this I have web, going into an emulator and disabling hpsa, but why you want to. I can't see it would save much battery life. I've come to understand battery life on my phone is meant to go quickly.

I don't want to disable this permanently, just while I'm at work. Its not so much that edge would save battery, its the constant switching between edge and hsdpa that kills the battery. Even sitting on the same place on my desk, it will sit there and switch without me touching it. I have fairly strong 3G at home and in town. I was hoping to avoid going into debug menus to disable this functionality that's normally in a vanilla android ROM.

Exactly! I used to have the same issue with my iPhone 4 but even it had a 3G toggle. If this all boils down to AT&T again...

Does other Samsung Galaxy phones have the option to turn 3G on and off?
If they do not, how can ATT be at fault.
They allow it, on the iphone. I will go and say is a samsung thing.

Either AT&T being themselves or Samsung with their hands in the android settings. Because vanilla Android has the capability.

AT&T is known for disabling this capability on all their phones. When I used to use Nokias a lot, the ATT specific firmware did not allow you to change that setting either.
I just tried the *#*#4636#*#*, but for some reason it won't save the setting. Do I have to reboot for it to take effect? I didn't seen any way to confirm the change.

Anyone come up with a solution?

[Q] No mobile signal on AOKP?

Hey guys!
I recently flashed AOKP, but as my device turn on, i enter my pin code, but i still don't have signal. The signal meter in the upper right corner is blank, and it says "no service" on the notification dropdown. It works on every rom but not AOKP. Does anybody know a solution?

Check ROM control and look in power saving options, see if it is set to disable network at any time. Mine was set to disable after screen was off for a minute, however it kept disableing my network during active times! Once I disabled power saving option it never shut off again. But with it on, my network was getting shut off over and over during
Activity. This could be your issue. I could not figure out what kept causing my network fail, then I looked into that. That was causing my issue. Hope this helps you! Hopefully thats the reason for your issue. Take a look and see. Best of luck!

Any idea what's causing this

It's like my radio sleeps sometimes. This screen shot shows no data. Once I wake my phone data reconnects. I don't think this is caused by no signal.
Sent from my SCH-I535 using xda premium

Looks like you live in a so so signal area, the closer it is to green then the greater your signal is. I would think that's an issue with the towers in your area cuz as you know the signal fluctuates often even while sleep.
Sent from my SCH-I535 using xda app-developers app

Thanks. I don't understand why it shows no signal when there was signal. As soon as I woke the phone it reconnected to the tower. There's a delay when it switches from 4g, 3g and 1x....This long area of red was probably the phone stuck in the delay between switching? While trying to submit this post I just lost data in a strong 4G area..... I don't get it.

How often within a day/week does this occur? That's still odd behavior that you lose signal or notice signal degradation while sleeping.
Sent from my SCH-I535 using xda app-developers app

This happens once or twice per day. Seems to happen in areas with less than great signal, that's why I think it is maybe getting stuck in the transition between 3g and 1x. No idea why it stays stuck once I move to an area with better signal.... Seems like the radio is sleeping until I wake the device.
Sent from my SCH-I535 using xda premium

It happened to me before. Try to go to flight/airplane mode and back. It should reset everything. I also sometimes press and hold the home button , then remove all applications and go to ram memory and clear it.

That does work but we should not have to do that in the first place. Hopefully a update will fix the data problems.

Are you stock? if no, what ROM are you running? Are you rooted? what apps are installed.
If you have CWM recovery, i would try to wipe cache and reboot, see if it helps at all?? if you don't have much installed, i would say do a full system restore...

one other thing, are you losing data, ie; not getting text and or phone calls? Also, check to see if you have any battery savers checked. Might be just a method of saving battery by shutting off data until it is needed.

I am on stock not even rooted. Phone is a week and a half old.... I am willing to wipe data if you think it would help.

As far as I know I am not missing phone calls or texts. Power saver is turned off. I am basically running the phone the way it came brand new (not many apps, no root, no unlock.... Yet).
Thanks for the replies. Any chance a factory reset would help? My mute/vibrate functions in settings do not mute the phone either... Still get audible notifications and phone rings like normal. Unrelated to the data issue but still weird for a new stock phone.
Sent from my SCH-I535 using xda premium

I'm not going to lie. I don't know if it will help or not. But if you are stock and got nothing to lose it would give it a shot. Can't hurt? Also, as others have said, it sounds ds like it could be because of signal strength. A lot of variables though.
Sent from my SCH-I535 using xda app-developers app

Data wipe did not fix the mute problem. I am very annoyed. Will see how my radio acts today after the wipe.

Just found a post on Verizon's forum regarding this problem. Apparently I was right when I said there was a issue when switching from 4g/3g/1x.

Now before I say this I want to make it clear that I am not representing Verizon or Samsung in any way with this post, I am just updating the users on what I have identified from the test of my device on this reported issue.... So with that said you can take this accordingly..
Ok everyone about the reported connection issues reported, I recently have been able to duplicate the signaling issue reported on my S3 and it appears to be miner for me at the moment but I can say that it is present.. I recently attempted to isolate the bug and I learned that when I placed it in my test rig to monitor the device in the weakest area in my house the software would temporarily powers down the radio for a few seconds that causes the device to loose all connections (Wifi, Bluetooth, 4G and some times also the network connection), this only happens in a weak connection area and it does appear it could be a software related bug with how the radio drivers handles switching the connection from one connection to another.
From the test results this does not appear to be a hardware issue but I do agree that this could be a pain for a user on the border of a 3G and 4G connection because any connection change causes a crash or radio and force restart.
I have reported this to CS and it appears to be a situation that is being looked into and a solution is possibly in the works... Eventho this isnt a major issue for me at this time, I hope to see a update to address this soon.

check any settings you may have done in the "Profiles" option? is that on a option in settings on the stock rom, lol, cant really remember

What a joke. This really irritates me.
Sent from my SCH-I535 using xda premium

This is frustrating. I have lost signal now two times and needed a reboot to get it back. When I did, I was not only losing data, but phone also. I would get this barrage of texts and missed calls.
I am rooted and unlocked, so there in itself could lie a problem, but it comes without warning and the phone appears to be working. Would the SIM card really effect that?

WiFi disconnects

Does anyone else experience WiFi drops from this phone or is there probably just something wrong with my router.

Settings -> Wifi -> Advanced -> Keep wifi on during sleep... is that set to always?
What ROM, Kernel are you using?

Yes always on is set, I have the issues on cm m9 and paranoid android.

Could be router problems. Stock kernel?

Yeah I always use stock kernel

The only thing I can think of is it being a router problem. Do you have another device around? Use that device and connect to your wifi and see if you can reproduce your WiFi disconnects, if it disconnects then its your router.
If you cannot, go to a friend or familys house or public wifi and see if you can reproduce your WiFi disconnect problem.

One more to back your clame up it drops my WiFi and my nexus 5 is still connected. CM need to get to work. This phone has been out for a while and things like this should have been fixed by now.
Still love it but glad I still have my nexus. Not being a fan boy just being truthful.

Yeah i have the same issue, my phones wifi goes orange every time it goes into deep sleep. It's really annoying

Do you guys happen to be using Snapdragon Battery Guru? Or any battery saving applications?

It's the phone. Not the router.
Does it happen on your other devices? No? Then it's the phone.

Someone else was having the same problem and had BatteryGuru installed which was turning WiFi off when the phone screen is off to "conserve battery."
Check your user apps guys.

Well I was asking that because they can be using those apps which are conflicting with wifi being disconnected when screen is on. I personally am not a fan of battery conservation apps, they don't do much in my opinion. Handling wakelocks and allowing ur phone to deep sleep is more important.

I am a very straight forward guy so please don't take me the wrong way.

It doesn't even happen to me when its in deep sleep...its when I'm actively using the phone. My WiFi will drop and my network will disappear from the wifi list in settings, then 10-15 seconds later it reconnects.

That exactly what mine does. Sometimes I have to reboot to get it to recognize my network. It's annoying to say the least. I may try another ROM to see if it's any better

Using another rom will not resolve the problem, the wifi driver is within the kernel not rom. Try using other kernels instead.
