Wifi problems can't figure it out ideas would be much appreciated - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I'm on the skyrocket and I have ran just about every ROM on here at some point and a while back my wifi started acting up randomly. By acting up I mean it would shut off and either attempt to turn on and end up in error or it would turn on after much longer than normal and start scanning but never finding any network then turning wifi back off. I tried all the usual methods of fixing things wipe cache and dalvik reboot, some times would work. Reinstall ROM, kernal, modem...works every time...for a while. Now on ics thought everything was ok then it happened out of no where like always... No wifi. Upgraded to mhx superlite 4.0 and hoping for the best. Thanks in advance

Do you have logging enabled on your router? Seeing any logs that are happening while the router is on/the phone isn't connecting could be useful

I do not but I'll have it ready for next time my wifi stops again could be today could be a week it's very random

Actually three only logs I could find on my router were "event logs" and nothing showed up from my phone when it was last having wifi problems

I've been trying to avoid Odin a I'm not very familiar with it I've only used it once or twice but never in my skyrocket but if this problem doesn't stopthat's my last option I believe... I've been hoping it's not hardware but we will see

Odin CWM?
Hi, I'm facing wifi issues as well. I'm a very new android user. I'm running SKY ICS and it was running great until this morning. I have lost wifi. Nothing has changed with my phone to explain this change in behavior.
Behavior:
Wifi is turned off.
I go in to turn it on, it will show the "turning on..." message in settings and will then show checked. Wi-Fi networks will then show "Scanning" and then wi-fi shuts off.
I had Wefi Pro installed and uninstalled it thinking that app may have caused a problem, but the behavior persists.
I have found Darkside and Odin via search, but can't find Odin CWM. Can someone provide a link? Thanks!

I've noticed that my wifi issues are associated with Juice Defender. It works good for a while then starts acting up. I tweek it. It runs better then acts up. Then I reflash and start over. Need something other than Juice Defender. I suppose I could probably do the same power saving actions with Tasker... but it's more work than I feel like doing.

I use juice defender and never had a problem. Check the wifi settig inside the juice defender profile that's responsible for re trying wifi connection if it fails. That's probably what's set to a high number.
Also, for the OP... Do you have any other wifi devices on your network that behave this way? And do you use juice defender as well?

Tethering help

Ok so when I try to tether my phone to the PC(windows vista 32 bit) it will connect but only for like five minutes then it only gets limited connectivity. 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

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 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.

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.

Wifi won't shut off

The usual apologies if there's a thread here on this already. I couldn't find one.
I've tried two KK4 ROMs, and on both my wifi can't be configured to shut off when the phone sleeps. It's a pretty significant battery drain, as you might suspect. I have trouble believing that I'm the only one with this issue. I haven't seen it before on any of the other 2.1-2.2-2.3 ROMs.
I've tried the usual - reflashing the modem. I didn't have the phone plugged in at the times of the flashes. I hear that can cause issues. But the same issue has come up with both Serenity 6 and Legend 2.
Am I missing something simple in the settings?
I have ran a few of the Fasty ROMS on my Cappy and all of them were able to shut off wifi while screen off. I believe its something he did to his ROMs to allow that.
Im not sure if thats a KK4 issue or not I just know it works on his ROMS

Random reboots in Bryan's kernel

While there may be another issue underlying, one of the more prominant reboot causes on the phone is wifi.
I believe I may have found the cause of the problem, and with that a temporary fix.
The problem had me at a loss because some people had it and others didn't, so I concluded it to be caused by either wifi channel or security.
Doing some scanning I found my own wifi to be running on channel 3. Opening the router interface I found the channel setting, like most routers, was set to auto. I changed this setting to 6 and no more reboots.
The fix
If you are running your own wireless router, open the interface and use a standard channel (1,6,11, 6 is recommended if you use wireless N with 40mhz channel width). I will not help you set up your router as there are plenty of tutorials out there.
Sent from my SGH-T959V using xda premium
Unfortunately for me this is not the case. I've had my router set to channel 11 for some time. It does not change. Also, I've had the problem occur when wifi on the phone was not enabled.
After reading a thread in the Dev section on this kernel about it possibly being signal-strength related, I figured I would do some testing with different modems. I first went to the KD1 modem and it seemed fine for almost a day, then a reboot. Followed by a reboot soon thereafter. I switched to KG4 and the problem got worse. I do believe, however, that when it occurred my signal strength to T-Mobile (not via wifi) was weak/nonexistent.
I'm still on the KG4 modem despite the amount of issues I had with it last (one time it rebooted twice within the matter of a minute).
I think Bryan may be onto something provided in a log regarding the WM8994 module/code.
I'm glad you're still trying to figure out the issue as my time is limited these days. I hope we can narrow this issue down for the folks having the problem.
Thanks for your efforts and time!
Yes. As I said it appears there are 2 issues. My phone had started to reboot almost every 5 minutes when connected to wifi. There does also seem to be another issue causing reboots, but for some this may help.

I misread the first sentence. Sorry about that. Weird that wifi is causing that issue. I'm tempted to set my router to auto & see what happens. I set a channel for it long ago because I have a repeater to get the signal to the other side of the house and they would hang if both were set to auto.

I don't get great battery life as it is. I did notice yesterday or the day before, though, that when it reboots itself, the battery usage shows a sharp drop. I also noticed it's not a "full" reboot, but rather seems like a quick boot.
I agree with the half reboots and it also seems to me that they happen when the signal is low. I get a couple a day and usually while using data or wifi while indoors or while coverage is low. I don't know if these details help track it down or not but I wanted to leave my experiences.

Just an FYI. I set my router to n only channel 6 a few days ago. No reboots til this morning. Normally it's "hmmm there it goes again." This morning however I thought I had broken my ankle and was waiting for a call back on what to do. BAM, my blue tooth disconnected, I looked at the phone and saw the beats audio startup. Really bad timing for a reboot. Wifi wasn't on. Glad I didn't miss the call back. That would have really sucked.
Ive pretty.much given up on finding it. Im waiting for my sdcard to come in the mail to test that. If that doesnt fix it ill be redeeming my phone warranty this weekend.

Don't give up just yet.
I'm using my Hebrew Valhalla ROM and using Bryan's kernel I had no reboots for more than a month. It's basically Valhalla Final with Adrenaline Shot 14.1 with system mount on etc init.d scripts. I'm also on sidekick kd1 modem. You can try this ROM, if you don't change locality to Hebrew it's as English as any other ROM.

You may have something there. I really don't understand how all the various work together, but seemingly there's something between the kernel and the modem. Since the reboots can be random though, it's hard for me to even guess. I flashed SCOM a little bit ago which uses the KD1 Modem with KJ6-v0.1.1-rc2. So we'll see.
Idk. It seams heat related. Also Bryan said that he either tracked it to userspace errors or he thinks its caused by userspace errors.

for those of you having the random reboot, did you do the gremlin removal steps + the factory wipe without the sd card in the phone? i would highly recommend this. after you have successfully done the gremlin remover, remove and reformat the sd card on the computer. while this is formatting, go back into cwm and wipe data/cache/dalvik without the sd card in the phone. once this is done, let the phone sit for 15 min or and and shut down. put the sd card in and reboot. if you still have random reboots, try the kh2 kernel.
I was going through the same reboot issues with kernels newer than 2D for a while. Then a few weeks ago I flashed FB's version and everthing ran great for a week. I was running VB with no additional tweaks of any kind. The week of no random reboots got me feeling good enough to start adding some of the typical changes I make to my phone... the first being changing some SD apps over to System apps ( Netflix, Skype, TB, Plume, Ninesky, ES File Ex, Camera Zoom FX & a few others)...BAM! Random reboots 4 to 5 times a day. Converted apps back after 3 days but the reboots persisted. Reflashed VB from scratch, keeping kernel that is packed in Raver's VB ROM, left apps alone and so far no reboots in 4 days. The only logs I found were similar to those posted on another thread where Bryan then said he didn't need anymore, he just needed time to de-bug.
Has anyone tried using the kj2 modem? kd1from SCOM was giving me random reboots left and right and after flashing kj2 last night my phone has been up for a little over 17 hrs without any issues. I know its not alot of time but its better than random reboots every hour or so. Signal strength also went up a bit.

I usually do the whole gremlin thing before every flash regardless. Actually formatting my sd on the puter as we speak. Then I'll do gremlin again, then reformat, etc. The things you mentioned at the end though I've never seen before, so I'll add those into the mix. With the SCOM flash this morning, the phone rebooted within 3 hours. I'm glad to see Bryan's back and that he's on top of it.
I had this problem and added the system mount on init.d scripts and the modem and don't have it. Never used the gremlin remover. So if the gremlin remover won't work for you as well, try what I say.

Ok, this is something I don't understand. I am loving the SynergyROM so far, and the stock ROM wasn't bad either. However, with the stock ROM, with WiFi off, it would still notify me when in range of a remembered network, and suggest connecting automatically. It still does this with the Synergy ROM, despite turning it off in settings or using the notification screen widget.
Is WiFi really OFF if it still somehow knows whenever you're in range of a remembered network?? It blows my mind that you can't really turn some of this crap off despite really wanting to. We have 4G where I live now (finally!!) and it's over FIVE TIMES as fast as any internet I can get at my house. STOP trying to connect to inferior wifi, hahaha!! Never thought I'd be complaining about this, but there you have it.
How do you really shut off the wifi? I couldn't even do it with the phone completely stock and unrooted.

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.

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.

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.

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.

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.

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.

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?
