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.

I've tried to diagnose from the PC but keeps telling me I need to contact my service provider. It will connect but goes back and forth. Would anyone be of assistance. Please and thank you

When i used mobile AP it also gave me limited connectivity for a while so i turned it off and then back on and it worked fine... im not sure what the problem was though

are you using wired tether or wireless

Ok guys I'm using stock tethering with USB. I've tried disconnecting and reconnecting and it will give full connectivity then it will drop to local only then in a few more minutes it will drop to limited connectivity. I just don't get it. It will connect but just losses connection like crazy. I will try a few apps and report back, in the mean time any help or ideas on what to do are welcome.

I've only used Mobile AP and Tether app to do tethering, never had an issue on those. Best of luck.

are you letting your screen turn off, and are you running any battery saver apps that turn off moble web when the screen turns off.?

I dont think it matters if the phone is charging or the screen is off/on. I used to tether with the stock app all the time no problem while charging and screen off for a long time.

I just recently started getting limited connectivity. I only use our stock Mobile AP. I have never used the usb cable to tether. I wonder if it is a result of something we flashed..
If we can figure this out I will be very happy!

I agree. It would seem it is due to some unforeseen issue that I would not no anything about. It seems like when the phone goes to sleep that's when the trouble starts. I haven't been able to test this theory as I haven't had access to a PC for a day or two. Will report back with you guys cause I'm gonna try a few apps and see if keeping the screen constantly on will help if it does then we will know it is something to do with the phone sleeping while tethering. Thank you much for your guys input..

I always turned my screen off and never had an issue before. This is recent issue for me. I'm not running any battery saver apps..I did recently flash a ROM that came with Bali 3.3 uv.
I never uv and actually flashed Bali 3.3 (no uv) this AM. Could the under volting be causing it? The last time I tethered was two days ago so I don't know if I still have the issue with Bali 3.3
Thanks

Ok. I have done some testing and definitely have come up with a fix for us. Is it a temporary or permanent fix? I'm not sure just yet. This is what I did.
Turned on my Acer laptop/let it boot up.
Turned on our stock Mobile AP as a wireless tether. I got limited access.
I right clicked on the signal status bars icon.
I got a popup with 3 choices one of which was STATUS.
I clicked on STATUS and the limited connectivity icon (triangle with ! In it) almost immediately disappeared before my status window popped up.
I HAD FULL CONNECTIVITY.
I browsed a little.
I shutdown/started up my pc 3 times and had full connectivity each time.
I then, for40 mins, downloaded ROMS, Kernels, Mods ect from xda and rootzwiki using wireless Mobile AP with no issue our loss of connection. I worked it good!
I am now shutdown and waiting for an hour to pass (another 30min) to test if I will have full connectivity immediately on connection.
I'll check back in soon. Hopefully I'm on the right track!
**Also**
My phones screen was off the entire time.

No. Audiophile Funk in the trunk as of yesterday but I was getting it on Black Ice too. Just started happening 10-14 days ago

@GDofWR420
Ok. I started pc/let it boot up and run. I then turn on Mobile AP (wireless).
It showed connected but there were no bars and the blue wheel was spinning..still early in its connecting process I'm sure.
I got the limited connectivity icon on the signal status bars and it said Limited connectivity in the popup.
I right clicked the signal status bars and immediately got Full connectivity. I didnt even get The 3 option popup with the STATUS option.
I'm still fully connected as I write this. My phones screen off the entire time.
I'm going to shut down pc and reboot phone and see what happens...I'm sure it is something we flashed and when the devices "talk back and forth" something happens.
Forgive my noob speculations and non technical replies. I'm REALLY NOOB with pc's lol.
If all we will have to do is right click the signal status bars here and there that wont be to bad.
I'm going to Odin stock (probably not tonight) and see how that works for us also...
BTW; I have been using your CWM advance restore guide and I'm loving it! Wish you did it months ago! What a time saver! Thank you for that.

Can't regain signal without restarting

Completely stock phone... I never messed with it from day 1.
So here's the thing... everytime I take a subway and after the get out from underground the phone never regains the 4g data icons... the signals are there but it doesnt let me browse the web or use any apps that require a data signal.
Restarting the phone solves the problem...
But at work everytime I go to the basement and come out.. I completely lose the signal and do not automatically regain it once I'm out on the street... this made me miss many calls and incoming texts... I also switched my sum card 2 weeks ago for the newest 4g Sims... it helped for about 2 days.. but now same thing happens all over again..
Any tips?

Try toggling flight mode on then back off.
Sent from my SGH-T959V using xda premium

Did that... it rarely works... but either way... its not good when a phone can't regain a signal... because its in my jeans the whole time... and I get a lot of missed calls due to that... its horrible.
Does anyone else experience this problem with their galaxy s?

If its completely stock I would call in the warranty.
Sent from my SGH-T959V using xda premium

If you've always been using stock, then you should try your hand at flashing GB.
Try out some new modems too. It might solve your problem.

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.
Sent from my SCH-I535 using xda premium

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?

[Q] Wifi and Mobile Network keeps resetting

This problem with my phone just started yesterday. My phone will be fine and then out of no where the Wifi and Data are turned off. It will turn back on but this happens constantly and my battery is draining because of it. I have a wlan_wd_wake wakelock as well. I dont know if this is related.I'm trying to figure this out but I am stuck. I can take a Catlog as well if that will help. any help will be greatly appreciated.
