[Q] Wifi issues with new 4.67.651.3 update

Ive looked around but havent found any answers yet.
Ive been noticing with my Wifi it will switch to 3g for a minute or so and then back to Wifi. no sure whats causing this.
Is anyone else having this problem or has someone found a fix that im not aware of.

I take it you're running a sense ROM? More details would help. :X

sense ROM yes
I was able to unlock the bootloader via HTCDEV and flashed a 4.67.651.3 DEODEXED sense ROM posted by brad560 in the DEV forum.
still looking to see if anyone is having this issue.

My dad'sphone is totally stock, and he has been complaining about the wifi not working right. I'll mess with it and let you know if I find anything out

I've been reading about the same issue over at Android Central.
According to one post if you change the WiFi settings to use a static IP but leave the fields blank the problem should go away.
I haven't upgraded my ROM yet so I have not experienced it myself.

Im having issues with my wifi also, n I dont no if its because of this new update.. I also updated the radio n pri. Does anyone else have this problem?
Sent from my PC36100 using xda premium

Wifi issues for me too
I also am experiencing the wifi dropping out for a few seconds. Luckily I had a backup I could reflash, but would love to know if there's a work around or a fix in the works.

Update : By changing the DHCP lease time on my router from forever to 48 hours, I do not experience the wi-fi drop issue anymore

its a known issue with the new update

Yeah, but at least there's a work around until they can get it fixed

I've only found this to happen with Belkin Routers so far. But the work around does work.
Sent from my PC36100 using xda premium

It was happening on my Linksys (flashed to ddwrt), but the fix for the Belkin routers worked in this case too. Haven't tried it elsewhere, such as public hotspots, but 99% of my wifi use is at home.

Phone call connection problem

Has anyone had an issue with connecting to phone calls with T-Mobile lately? I have tried 3 different radios on multiple ROM's with no luck.
Problem kind of goes like this. I'll make a call....phone will not ring and sometimes say call connected, sometimes it won't ever do anything. I'll hang up, call right back and it does ring. This doesn't happen every time but it happens enough to piss you off.
Any help would be great. Thanks community.

I have the exact same issue. Don't know what is causing it. I have also tried different radios and ROMS. Seems to only have been happening on Jelly Bean ROMS, but don't know if that is a cause, or just that I have only been on those ROMS for a while now.
What Radio/ROM are you using? I am on LiquidSmooth with the UVLH5 radio.

I'm currently on the UVLH radio and PACman latest release.
This is annoying, not disabling my phone but annoying at any rate.

Yeah. I have noticed it a lot when I call my girlfriend. It will say it's connected but I won't hear anything and usually it will disconnect. So if it starts doing that I have started hanging up and recalling and it rings from the start. I just found out today though that it is ringing on her end even though I am not hearing anything. She said most of the time I call it rings, I hang up, and then call right back, but to me, it seems like it's not connecting the first time.
Same thing happens sometimes when I receive calls, I will answer and hear nothing and have to hang up and call back. I wonder if its a T-Mobile thing in our area.

This is a typical issue with Samsung phones and T-Mobile and has been noted in multiple threads.

I haven't seen the problem anywhere before. Hopefully it will work itself out. Stock ICS I didn't have that problem. Just with JB.

Data problem on hellfire cm10 rom

I just flashed hellfire cm10 ROM two days ago its been running great, so much faster. Small problem I'm having is that it can take a few minutes to pick up the connection. Eventually will turn to 4g. I have a really good connection where I live and on stock jellybean or ICS rom. Picks up the connection instantly. I have latest cwm and I cleared everything necessary. And fixed permissions after flashing. Any help would be greatly appreciated. I have flashed all the at&t modems, makes no difference, although I wasnt sure that it would.
There's something I'm forgetting to add I'm sure. Its only an annoyance really but if I ever want to check my stuff online really quickly I can't', because it takes so long to connect. At work it becomes impossible to go online.

Check your imei in settings under status. By chance does it show 0 or unknown? Or something else? If it is correct then just ignore this post. If it's not, then you likely have a major problem on your hands. All is not lost though

[Q] d2usc - 4G issues

Hey all, I'm at my wits end trying to figure out what's going on with my phone/service. First off I hope this is the correct forum since none of them officially address the US Cellular version of the S3.
So what is happening is that my device seems to only want to connect to 3G. I am running the latest nightly for CM 10.1. It all started last week while I was in the twin cities on data roaming for a few days. On my drive back to Wisconsin I notice I would go in and out of 4G service.. by the time I hit home I was on solid 3G service. This was last Friday. I knew there was some work going on the towers in the area as my brothers 4G service started working on Sprint. I just assumed it was something to do with that.
By Sunday and still on 3G, I called tech and they did everything under the sun to try to get me back on 4G to no avail. They ended up sending me a new phone. When the new phone arrived on Tuesday I did a factory reset on the old phone just to clear everything before sending it to them and I noticed it went back on to 4G. This was on the stock ROM, rooted still.
So I switched the phone over to the new one and sure as hell, comes up in 4G. I replaced the recovery and restored a backup I had.. phone pops up.. 3G. :crying:
I did a factory reset a few times and nothing.. still would only come up in 3G mode. I then restored a backup I had for the stock ROM and what do you know.. 4G. Flashed a fresh download of the stable 4 snapshot.. 3G.. then I did a factory reset and what do you know .. 4G.. reboot the phone.. back on 3G.. Tried AOKP.. 3G..factory reset.. 3G.. Back to CM 10.1 nightly.. 3G.. factory reset.. 4G.. reboot.. 3G.
I cannot figure out what the hell is going on.. it clearly isn't hardware as it's now happened on two phones. I thought it might have had to do with being on data roaming for a few days so I waited until the data billing cycle finished (the 6th) but no luck.
I'm at wits end.. I will try anything at this point to get it working again with CM/AOKP.. doesn't matter.. just want my 4G back!

Your phone does not have 4G, It has HPSA.
On AOSP/AOKP, your connection will show up as 3G until it's being used. Let's see some speedtests.

Don't go by what it says in the ststus bar. What does it say inder Settings > About Device > Mobile Network type?
Now go start a large download, like a rom or something. While its downloading check again and post what you see.

Speeds
Thanks for the quick responses guys..
First thing was my status bar was showing 4G for about a year.. it was just recently I started having the issue. I used to get about 20Mb/sec down and now I'm getting about 800Kb-1.5Mb. It's clearly much slower than it was.
And the network type is CDMA - EvDo rev A:6

Try going under Settings, More Settings, Mobile Networks, and try a different network mode.
Sent from my SGH-T999L using xda premium

Its selected as LTE/CDMA/EvDo. The only other option is CDMA/EvDO. I think it's set correctly.

What about Network Operators? Have you tried checking or trying a different one?
Sorry, I just don't know much about the usc model.
What is the model# btw.

Not sure what you mean by network operators but the CDMA subscription is set to RUIM/SIM (which it should be) and the System Select is on Automatic and not Home Only.
Model is SCH-R530U

Under mobile networks you can manually search for and then select an operator.
Judging by your model number, you will likely find more and better help and probably others with your phone in the Verizon forum. (Possibly Sprints, but most likely Verizon)

Thanks. I think I found the answer.. some code in CM 10.1 was causing the NV to lose it's information. A code change was put in to prevent that from happening.. I just need to go back to stock and flash back to CM.
Thanks for the help guys!

Everything I've read involves going back to stock, factory reset, and reflashing. Is there any way to resolve this without reverting to stock? Or is that the only way? - Does it need to be unrooted? And also, one thing I was curious about, I have a stock backup, would flashing that, and then reflashing to a current CM backup do anything, or does it need to be a clean flash?

I would go totally back to stock and start over. It wouldn't even take more than an hour to do everything.

Yup, if you're having problems, taking shortcuts often result in more problems and more time involved than just starting over clean.

I was having the same exact issue on CM10.1 RC5 -- called US Cellular and eliminated everything but CM causing the issue. Flashing back to an earlier version of CM, trying RC2 first.

Do you have the SCH-R530U? If so, see my quoted post below.

I do have a SCH-R530U -- tried looking around for info about the SCH-R530U and 4g, didnt find anything. Do you have a link? Thanks!

Verizon has their own separate forum and you can get to it from the main forum page. Go into q&a and use the search this forum searchbox.
I'll try to get the link in a bit. Bout to leave for a while though.

Went the revert to stock and reflash route. Issue is resolved. I did have to do it twice, as after the first reboot with RC5, I lost 4G again, skipped it and am running the 6-19 Nightly and have had no further issues! Thanks for your help. You guys are awesome!

Losing service

I searched and didn't find anything. So my problem is I have a stock i317. I randomly lose service. Sometimes it's just data, I'll have 3 or 4 bars but no data. Other times it is everything just the no service symbol. I usually turn airplane mode on and off and everything comes back. Any idea what the problem could be ? I just updated ota to ucamh3. Hoping that would solve the problem but there is no change.

Some devices had internal antenna issues that required a repair /replacement ....
If a stock rom is used and the device has been factory wiped ...but you still get antenna issues ...
The device may have a problem ..
It's not uncommon ...
And if the device is truly stock and no tampering has occurred ...then the odds of a hardware issue certainly go up...g

I found what works with my phone is a quick smack to the thing. On the side or the back Im not sure I hit it a few times. Then it goes from not being able to find a network to having full signal strength. Im not hitting it hard enough to hurt it. I hope this continues to work for me.
(Update)
Upon further testing smacking it does not seem to make a difference. We are on Straight talks BYOP sim plan using AT&T towers. My wifes skyrocket does it sometimes and has Cyanogenmod Rom. And my note2 I just got and immediately flashed with Pac Man Rom does it a lot. Cyanogenmod Rom has some of Pac Man rom built in it hmm. My skyrocket never does it and it is still stock 2.3.6. Im thinking of doing a nandroid backup of my hard work setting up my Note2 and then flashing back to stock to see if it still does it. Or try to see if it only does it on a low charge. Or only wail plugged it. Or flashing a different radio, or different modem or baseband how ever you are supposed to say it.
Right now my Note2 is on baseband I317UCAMCE.
My working Skyrocket I727UCLD2.
Wifes Skyrocket I727UCLL3

Yea i have tried different roms now. It was official.tried a couple diff roms. Just did the new leak and sll having same problem.

Iam having a very similar issue with my Note 2(sgh-1317).
If you could please walk me through this. Permissive and Enforced are both greyed out using WanamSELinuxModeChanger. It is rooted(CF-AUTO-ROOT), os IS 4.3, IMEI under battery matches IMEI as listed under [SettingsAbout Device/Status] as well as that listed using Android System Info from play store. Radio is "UNKNOWN", KNOX status empty
This is the 4th phone, all note 2s, that I've had "No Mobile Network" issues with since I originally got this device last Christmas(2012).
the 1st 3 were replaced under warranty by AT&T. But now I'm on Straighttalk and rooted and the issue remains.There is an iPhone 4S in the house, also on Straighttalk, that has no network connection issues at all. I have verified APNs etc etc and am at a total loss.
Any help is much MUCH appreciated.
thanks
