Hi guys,
In December, I started having problems with my WiFi. When I go into Comm Manager and press the WiFi symbol, I get the WinMo6 "spinner" to let me know it is thinking and then nothing.
Since then I've tried 3 or 4 different ROMs and I am still having the same problem. Is it just time for a new phone? Does anyone have any helpful hints or things to try?
Thanks in advance.
I got this exact same problem too....
Does anyone have any idea how to fix this? I would really like WiFi back.
I have a similar problem but it will turn on, find the AP but not connect. I have a g-only router ang a b-only router (both unsecured) it will not connect to either, it'll try for a few seconds then stop. I have activate the connect to G router hack in the registry.
from will
As a note, I just turned on the Today Item "Wireless" and WiFi doesn't show up at all. Does that give anyone any clues?
my phone sometimes does this not-connecting-to-available-router-trick, then my usual procedure is to reboot the router.
Sometimes it shows the Icon as connected, but in reality won't even turn on the WiFi, even after a reboot. Then it's a bit more complex... I switch off the AP, then the wireless subsystem, reboot the phone, while it's booting reboot the AP, and THEN activate wireless. This usually shocks it back into sense and it connects just fine. This usually happens after I accidentally use the popup window to control the WiFi, or sometimes randomly. Small problem, but when it happens, pretty annoying...

Yep, sounds just like what happens to me sometimes...
I happened to have same problem with my jasjar for about a year,,,
i started to believe its a hardware problem ...
the thing is i have tried all available ROMS official and not....but sometimes it works most of the times it dowsnt...
well program conflict is not the answer coz even after formatting i still have same problem....
What radio version are you guys using? I think I have 1.18.00. I am using Laurentius26's 2.05.00 ROM.
Guys,
Get a copy of TaskManager and check in the devices tab and check the wlan, also check your services tab.
It is likely that you either
1 Have a bad flash
2 Have a corrupt/unsigned driver
3 A hardware fault
My guess would be 2
Thanks for the response, Beast.
I see this: $device\WWN0(WWN0 Status: Loaded. Startup Type: Automatic. Dll: wwan.dll. Reg Key: Drivers\BuiltIn\WWN
I can stop it and restart it but it doesn't seem to do anything... Any ideas?

check out ZCF1 (zero config) device.
is it okay/loaded? which dll it uses?
and is there any other device that's unloaded?

Mine would be 3. I'm using your ROM, so I trust you didn't include bad drivers
Although when fixed the way I said, it works A-OK...

ZCF1 is loaded and using WZCSVC.dll.
There are 4 unloaded devices: DSK3, DSK2, COM8 and MIX1.
Thanks for your help as well. I hope we can get to the bottom of this.
mzalan - your problem seems different then jrronimo's.
mzalan's problem seems somewhat like something i experienced 2 days ago - relating to the wpa-tkip fix.
although i think your problem has nothing to do with the router, i think rebooting your phone is what does the trick. am i wrong?
i've made a cab for the wpa fix. after installing it my problems were gone.
give it a try - couldn't hurt.
jrronimo - maybe you should give it a shot also?

Yes, you are wrong, I must say. You see, this only happens in the dormitory where stay during weekdays at school. There is one wireless AP there, a small Linksys unit, which only stops working if there are many connections through it(solved, since I limited the number of clients in the DHCP to 10, whit a 30min lease. The tech-man forgot to set a new admin password), or if the flow is too great. My tech-savvy roommate says it dies because the processor is too weak to handle the flow or the many connections, and the firmware hangs, that's why it needs to be reset.
The other thing supporting me is that those are the times when everyone with a laptop in the dorms comes running to me, or just yelling down the corridor for me to "do something about the net". So it can't be my phone only.
The second case, where the icon shows me as connected, however, is only the fault of my phone, but even then the router needs to be turned off before I reboot the phone to sort of "shock WiFi system back into life". Luckily, this does not happen often. But these are the times when everyone keeps asking why there was a drop in the service...

Well, I tried this and it didn't seem to help or hurt. I now see ZCF1: as having the driver wpatkip.dll but loaded or unloaded WiFi doesn't load.
A few times over the weekend, though, it WOULD load up (before I tried the .cab, I think)... but then it would turn itself off. Also, the page in the network settings where you would normally see a list of available access points is just sorta... gone.
sounds like your registry is corrupt. I would format the doc with mtty Task 28 55a and re-flash your rom mate.
That sounds scary but I'm certainly willing to try. The registry doesn't get overwritten when a new image is installed? Eesh.
So... what do I do? heh. I hate to be a noob about it but mtty is not something I've had to deal with before.

Firstly you need to download MTTY, it's floating around this Forum somewhere.
Secondly read the wiki http://wiki.xda-developers.com/index.php?pagename=Universal_Technical
This has details of all commands accseible through MTTY.
Yes the reg should be cleared when flashing, however it requires user input to "Clear Storage" after a flash, and it is possible that the DOC is corrupted.
If you still have questions after searching on MTTY, post back and we'll give more help.
This may be old news for many of you, but I just found this last night so I thought I would share. The flashable update .zip from the linked post worked wonders for my Captivates GPS.
Here is the original post: http://forum.xda-developers.com/showthread.php?t=782242
I flashed the file from clockworkmod recovery and my gps is markedly improved. It's not perfect but it is much better.
Just thought I would share this with those who didnt know about it.
I also attached the file that I used.
Just for references sake so that we are comparing apples to apples, I am using JH7, rooted with unhelpfuls 1.4.1 kernel.
my mistake. i reset the supl to auto config. I also realized that clockwork uses the internal SD as default so i was reinstalling my root update.zip i still had on the internal. I was trying to install without clockwork in the beginning so i just renamed it to update.zip and threw on my external 16gb but it was installing update.zip from my internal. It works great and i have a great lock within 6 seconds when I have never seen a lock on my device. I even rebooted a couple times to get my lock right away.
Thank you again!

Awesome! Glad I could help even a few people. I knew I couldnt be the only one who didnt know about this!
just an update. Overnight, the GPS magically stopped working again. I havent been able to get a lock at all and have a max of 4 sat. connected at once on a sunny clear day. Any ideas?

Is wifi on? Wifi on its way hard too lock. Or try the Ms based trick a few pages back or the thread itself .. if wifi was on, exit maps or GPS test completely and turn GPS off, then turn GPS back on and try again......

Mine stopped working as well as when I first flashed but still works much better.
I used the LbsTestMode hack to change to the supl.google.com settings and it helped it a little more. Like I said in the original post, this isnt perfect, but its still an improvement over stock and it gives me hope that this is correctable via software. I had all but convinced myself that the hardware and/or design was faulty.
-D
I dont remember what i did but the gps is now working again and it works great, even from inside sitting near a window. I know that it is a result from these files posted. I also set all my settings to :
Application Settings
session type: Tracking
Test Mode: S/W Test
Operation Mode: MS Based
Start Mode: Hot start
Gps Plus: On
Dynamic accuracy: on
accuracy : 100
skyhook: on
pc tool: off
SUPL/CP Settings
Server FQDN: auto config
SUPL Secure: On
AGPS Mode: SUPL
I hope these settings can help someone else. I dont know why my gps cut out before but after flashing the OP files and changing settings to these, I can get a lock indoors without WIFI on.
Also i never have wifi on unless I am in the house using youtube or downloading stuff.
Thank you again for the files! I was using my GPS all day with no issues. I owe you big time because my phone never saw a satellite lock before flashing these files.
---------------------------------------------------------------------
EDIT
---------------------------------------------------------------------
I was having issues again today and changed to supl.google.com with 7276 i believe and it works perfect now and has been all day. I lock within 5 seconds of opening google maps. I now dont care if they ever release a GPS fix because mine is perfect and I wouldnt change it.
Hey everyone
i'm pretty new to the whole nexus s scene, as i've had this device for about a week now. I've rooted my phone successfully and i'm running MIUI's latest ROM..1.8.5 i believe. Now for the problem..
For some odd reason I'm unable to connect to my 3G network at all (yes, data is enabled in the settings, and set to 3g prefered/2g/only 3g..still nothing). Usually there'd be that green "3G" on top bar of my screen, but it doesn't show up. Now i rely on wifi to go online, which isnt a problem...but it feels like my money's being cheated if i dont use my data in occasional situations. I've tried flashing it again and again, but no results. I've flashed my phone to the Oxygen ROM, and the little 3G icon appeared, indicating that data is enabled (i forgot to actually check if it worked LOL). I haven't found anyone else experiencing this problem with MIUI, but i've found threads on them having some sort of difficulty with their data. If anyone could help me out, or direct me to a thread that has a possible solution, i would really appreciate it ~ thank you in advance.
Also, I'm on Fido.....if that helps.
I'm on the latest miui and I don't have that issue try toggling the airline mode to see if it will kick it in. If not really download the Tom and do a clean install see if that works.
Sent from my Nexus S 4G using XDA Premium App
hey, i've tried toggling the airline and it doesn't help. also, what do you mean by "the Tom"?
What happens when you try to connect with just 3G (what type of error do you receive)? Miui's stock 3G icon is white
Also, I think the other gentleman meant to spell ROM

He meant rom, auto correct changes the word rom, I think you need to wipe and reflash the rom.
hey, i've just tried reflashing the rom...and still no 3g ): !
also, when i enable data, and set it to 3g..there's no error. there's simply no "3g" icon on the top, and i can't connect.
Did u try manually inputting your apn? Sometimes providers don't push the settings to you
what exactly would i put in for my apn? sorry, total noob here :/
Go to menu>settings>system>mobile network setting>access point names. Do u have an entry there? You should. If not, you need to check with your network provider for the settings.
i've just tried putting in the APN settings (copied the stuff from the APN settings when 3g works on the oxygen ROM). is there anything else i havent filled in and should? cuz....it still doesnt work
Not really. Create it, fill it, save it, choose it and restart. Should work, it always did for me
How's the battery life on that rom
Seems ok to me. 3g uses alot of juice since the service is crappy in my country. Otherwise, best rom I tried
dang :/ still nothing... i've noticed something though. when im on my oxygen rom and search for networks..the option "Fido" pops up. when im on MIUI, the option "Rogers Wierless" pops up in the place of "Fido" .___." that may have something to do with it...
Same problem here on desire s.
When I try to change the apn setting I get a force close.
Cheers, Cor

I am unable to get the GPS to lock on ANY Gingerbread ROM and I have tried at least 5 of them.
On GB I will pick up anywhere from 2 to 5 sats and not lock on any. As soon as I go back to FROYO I pick up 11 or 12 sats and lock on most all of them.
This is driving me nuts. I have tried every single trick I could find posted online but can never get the GPS to work in GB, only FROYO.
So did you try this fix??

You lost me there. First of all the link you posted doesn't mention anything about doing anything else other than changing the GPS.CONF.
Despite that, from doing this so many times I was aware of that, so after changing the CONF file I rebooted, then I cleared GPS DATA, then I cleared and downloaded GPS A-DATA.
Then what do I do in LBS mode that I haven't already done in angry gps? Isn't ANGRY.GPS basically the same as LBS mode?

And what is GPS data a? You can't run any.other GPS fix apps or it'll block configuration from working.
Follow the configuration instructions,don't have any other GPS fix apps installed.then reboot after you back other GPS file up and put new configuration file in, after you reboot go into settings, applications and clear GPS data. Then go into lbs mode into supl settings and make sure its on auto config. Then run lbs test until it locks. That's best I got bro that's what fixed mine and four of my friends and some on here as well. Like I said alleluia phones are different. Good luck and best wishes

Absolutely not. The "fix" only replaces the GPS.CONF. If you look at GPS.CONF in a text editor and remove all the notation("#") lines it is virtually identical to all the other "GPS FIX" attempts out there.
GPS.CONF file remains the same no matter what you do with the A-DATA (I have looked at the file and settings after clearing the A-DATA. The A-DATA (assisted GPS data) is what is downloaded from the web periodically to put your GPS in a "general area" so it will fix quicker. That is the same thing that is cleared when you use angry-gps. Believe me, I have tried it without doing that and with doing that with the same results.
This "fix" works great in Froyo as do the umpteen others out there. When I use it in Froyo my GPS locks super fast but for whatever reason there is some problem with my phone, GPS and GingerBread.
I'm going to order another Infuse just for the heck of it and see if has the same problem. That way I can put them side-by-side. Just the fact there are so many "GPS fixes and hacks" for Samsung phones out there says something in itself.
Well, I got it working.
I went back to the "stock" GPS.CONF that was in the Serindipity VII ROM and loaded GPSTEST. I set it on a chair in front of my house. After about 45-50 minutes it finally "found aka in-view" 12 sats and locked on 8,
One it "finds" sats (not locks, just finds) it will remember those 12 or whatever number of sats until or unless you "reset GPS A-DATA" or "clear data" with angry GPS. When I do that I have to go through the wait again. Even in my basement it now always shows those 12 sats as "IN VIEW" when obviously they are not What is "In View" is probably the cached A-DATA info because if you clear that they are gone. The "faster lock" is created because the GPS "knows" what specific sats to eventually lock on. As long as I don't delete the data again, or travel 1000 miles from here, I should have no problem.

Me too. However these GPS issues across all Samsung phones models have pretty much turned me off to this brand.
Good evening guys-
After updating from ICS to JellyBean, my gps cannot find or lock onto any satellites.
If I enable wifi, its accurate to 20meters.. If not, it won't lock even after 15 minutes.
Any help is greatly appreciated-
mine has been similar in PA2.00 and CM10.
It actually will lock after a long time. Sometimes up to 30 minutes.
Interested in any answers... I noticed in the gps.conf file agps appears to be off. I don't know if that is the issue.
Unfortunately searching for a fix just reveals too much information with a lot of supposed fixes, but no consensus so far as i can tell.

Actually agps was turned off to improve lock times...some people noticed no difference with it off, others noticed huge improvements with half the lock time
You can change it to true, then wipe cache and dalvic cache in recovery and see if it makes a difference

is that a 'go ahead and try it, it wont work, but go ahead and try it anyway' ?
It seems like a lot of people are having problems with GPS in jellybean, and some aren't. There's so many 'this worked for me' solutions, but I'm starting to think it's coincidence.
Someone mentioned installing and running copilot once. Did that. it didn't work. Without root permissions what could it really change to improve anything?
I ran Faster Fix. It edited my gps.conf file (which it doesn't tell you that it does) It didn't help. it might have made it slightly worse.
I found a few other gps.conf files for jellybean ROMs, but haven't tried those yet.
This is how we learn and share our info, by trying. Just make a back up of anything that you want to change or replace.
GPS works perfect on my PA Jelly Beaned Infuse. First I ran GPS Test, it took a good twenty minutes if not more for it's first lock.
But now, I get a lock in a few seconds.
GPS Test, is free in the market.
Planning my escape!
GPS Test has kicked my GPS in the butt and got it working with almost every ROM I've flashed. Once you get over that first delay (downloading satellite data?) the first time you run it, it locks on fairly well afterward. At least, that's been my experience

I've already done that. It helped the next time I ran maps. When i left work yesterday I had maps give me turn by turn directions home. It took a couple minutes to lock, but after that it was working.
Then this morning I tried again. It wouldn't lock at all on the way in to work this morning. (only a 15 minute drive)
I also tried editing my GPS conf file this morning. I tried using ES file explorer, root explorer, and flashing. All three resulted in an empty file. ES says it was successful. Root explorer gives an error message 'there was not enough free disk space to complete the paste operation'
Flashing says it was successful, but again, it ends with an empty file. 0 bytes.
The file i used for the flash attempt is here. http://forum.xda-developers.com/showthread.php?t=1817558
With the gps.conf file I'm going to go leave the phone out in my car with gps on and see if it locks.
I understand that developers do a lot of work on this. I'm not trying to be a jerk. I just see a lot of people having the same issue and no agreement on a solution or even what the actual problem is.

I believe this is because there is no solution. If you want to try to help solve the problem, "adb shell" in and start tinkering.
You'll quickly find that GPS is anything but an easy thing to fix. A good SUPL provider for you may be completely different for others.
I can't find the Answer that fixed it for me,
but what I did:
Plug phone in, disable wifi, leave phone near window, and let
https://play.google.com/store/apps/...251bGwsMSwyLDYsImNvbS5hbmRyb2lkLmdwc3Rlc3QiXQ..
that app run... :45 minutes later it locked (GPS icon on Status Bar stopped blinking and showed locked, solid) with 7 satellites.
waited, rebooted the phone, and it locked in about 3 minutes.
-hope this helps.
other than that, love this ROM!

I believe this is because there is no solution. If you want to try to help solve the problem, "adb shell" in and start tinkering.
You'll quickly find that GPS is anything but an easy thing to fix. A good SUPL provider for you may be completely different for others.

Now that is an actual answer.
I suppose part of the problem for us noobs sorting through 300 page threads is all the filler with people saying "great rom omgz so awesome" even when they are posting on the first page and the ROM hasn't even been up long enough to do much more than flash it and swipe through the home screen.
All through out the CM10 and PA threads there are people saying GPS is working flawlessly... and then other people saying they have some fix. I guess people aren't supposed to post frivolous stuff in the dev threads, but they do.
Anyway, I ended up going back to GB as GPS is something I really need.
Hey guy's, i've also been having allot of issues with GPS just not being what it used to be, and it's pretty obvioius that this is an issue across the board for all JellyBean roms. I think those who mention that "GPS works flawlessly" don't quite understand the issue with AGPS (Assisted GPS), or they are not quite testing it thoroughly enough to see the problem.
To get an understanding of what AGPS is, and how it helps improve initial lock times, have a read here: http://en.wikipedia.org/wiki/Assisted_GPS
Also, to gain a better understanding of what I mean by "cold start" as you read below, and how it differs from a warm or hot start please read the following: http://m.gsmarena.com/glossary.php3?term=gps
That being said, i have been doing allot of digging in the hopes that someone out there has a solution to the problem with AGPS on the CM10 based ROMs on our phone.
To clarify the problem: AGPS does not seem to work and Initial lock times from a cold start can take several minutes, (this is not normal if AGPS is doing it's job). To clarify further, no one is saying that GPS does not work, it does in fact work, it just takes it's sweet time to lock and it seems to rely on pure GPS to download ephemeris data from the actual GPS birds for satelite lock acquisition, rather then downloading AGPS data over the network to speed things up. After the initial lock though, GPS functions as it should. After this point, if you do not use the phone again for several day's, it seems that upon first firing it up again you will experience the long delay in first lock. This is especially true if you keep GPS services turned off ussually to conserve battery. Those who report GPS is fine are probably keeping GPS services on all the time, and your GPS is probably working in the background at times and obviously will start up allot faster then it would from a cold start. (This is where i believe all the conflicting info comes from!)
The only info i have been able to find that did actually have an impact on my lock times was the thread below.
http://forum.xda-developers.com/showthread.php?t=1881655
I just started testing this out yesterday and i have seen some positive results. But i would caution those of you out there, and say that this is probably not a "fix" per se, but it did help cut down lock times in my case and at the very least it is a very inoformative thread that everyone should read.
What i have realisticly been able to achieve from a cold start is about 75 seconds to lock at the fastest. i.e. GPS services were off, i turned them all on, and now i started up GPS Status or GPS Test to get a lock. After that, as long as I haven't rebooted my phone it takes only a few seconds to lock.
How i tested, i started GPS Status, I then went to Tools --> MANAGE A-GPS STATE -> RESET (This is important to ensure you are clearing previously cached data. We want to make sure your previous cached info does not skew the effects of your changes.
I then replaced the gps.conf with the one contained in that thread, and i also made the change that was suggested in the Notes section that suggested modifying or adding a line in your build.prop file to "ro.ril.def.agps.mode = 1". This change set's your gps to use AGPS in Mobile Station Based (MSB) mode. For reference, setting it to "2" would set your AGPS to function to Mobile Station Assisted (MSA) mode. (Mode 1 - gave me more accurate initial locks at the expense of a bit longer lock times, Mode 2 gave me slightly quicker initial lock times, but was rather flaky and my position drifted quite a bit until GPS was running for quite some time.)
If your curious what is the difference between the two modes, see here: http://en.wikipedia.org/wiki/Assisted_GPS#Modes_of_operation
After making the changes to gps.conf and build.prop i rebooted my phone. When phone reboots, i then go back into GPS Status app, select settings, Tools --> MANAGE A-GPS STATE -> RESET, and then back to settings, Tools --> MANAGE A-GPS STATE -> DOWNLOAD (This should force the phone to attempt an AGPS download, if it hasn't already done so upon launching the app).
I have seen this same gps.conf being used in the newer RemICS-JB build. However based on the lack of feedback in that thread, i don't know if this is the golden fix we have all been looking for.
Even though this may not fix all your issues, i hope at the very least it helps clear up what the actual problem is, and how AGPS is supposed to work.
** Important Notes: **
- The version of the config that i was using was the Download the Google Specific No-SSL v3.1
- If you use the SSL version, then it will also require that you download the certifcate file. It's best to just stick with NO SSL as is explained in the thread.
- You should also note that i have cleaned out all the live wall papers, face unlock, and allot of other crap that i don't use to free up space in the /SYSTEM partition. I now have aproximately 21MB free in this partition. I think at least part of the problem with certain ROM's is that they have the /SYSTEM partition filled to the max with virtually no free space at all. I'm no expert on the subject, but i'm guessing that the AGPS data get's downloaded to this partition some where. Obviously if there is no space, then that would cause issues. Several others have reported shortened initial lock times after making room in the /SYSTEM partition.
- Another mistake people are making when testing AGPS and reporting false info, is having their WIFI on when testing GPS. To isolate the issue guy's you need have wifi off and you need to use a tool like GPS Status or GPS Test that shows that actual lock to satelites. You cannot properly test this and see the issue by using WIFI and turning on Google maps. Google maps will look at your reported wifi position and to you it looks like bamm.. i just got a lock in 2 seconds to withing 50 meters, wow these guy's are nut's, my GPS is awesome. Guess what.. your wifi and google maps is awesome.. not your GPS.. lol
- If anyone is familiar with running log's, it would be great if you could do a comparison of before and after. Showing the log of a completely fresh JB build, that shows that the AGPS data is not being downloaded, and then another log after all the changes above (including freeing up space in /SYSTEM) and hopefully it will show that AGPS data is now being downloaded and utilized. I myself am not familiar with logging data on the infuse, so i cannot and will not call this a fix until someone can actually show with real log's that AGPS data is now being utilized after these mods.
Thankfully, I'm one of the lucky ones who have always had a working GPS. It worked great when I was running AT&T stock Froyo, really good while I was on XDA GB roms, and fair > good after I went to PA JB. By far Scott's latest release of PA JB has been the best in this respect, but I can't help but tinker now that I've turned into a Droid zombie Strictly speaking the stock GPS configuration included on Scott's PA JB ROM worked charmingly, but I still had an issue whenever the phone went into deep sleep (say overnight without using it) the GPS lock the next morning took almost as much time coming from a sleep state as a cold boot. So, Like DaMeatMan I decided to give http://forum.xda-developers.com/showthread.php?t=1881655 a go. I chose the flashable option, and like DMM also edited the prop file. I picked the Google "no SSL" version 3.1 instead of the AT&T specific version. I figured I would give that one a try.
I'll keep everyone posted, buy my first impression (could be placebo effect) is that this configuration file and modification actually does improve over the original PA JB configuration by a small margin. Reported accuracy is better (by 10ft on average). Satellites in view and actually locking are 1-2 better than before. My main hope is that I can actually fire up Navigation in the morning and get working directions without having to fire up GPS Test first and relock all the NA satellites. I travel a lot, both for business and outdoor sports (hunting and fishing), and I have come to rely pretty heavily on GPS. I got spoiled when I got my first GPS capable phone because that meant I could leave my handheld GPS at home most of the time and that was one less thing I had to carry.

I have been have many of the same problems as others in this thread but I tried the fix in the S3 thread quoted above and it seems to have helped for right now. The first time I ran GPS Test after rebooting it did take a while (5-8min), but after that I get a lock in few seconds. I used the Google "no SSL" package also. I will do some more testing tomorrow and see if its reliable.
